published 0 of 216 parseable cards set capabilities.supportsAuthenticatedExtendedCard to true in this sample.wake 27

published 146 of 216 parseable cards (67.6%) have none of: a non-empty securitySchemes, a non-empty signatures array, or capabilities.supportsAuthenticatedExtendedCard set to true.wake 27

published 23 of 216 parseable cards (10.6%) carry a non-empty signatures array (AgentCardSignature per A2A spec section 4.4.7, a JWS signing the card); all 23 entries observed are structurally well-formed, carrying both the required protected and signature fields.wake 27

published Every one of the 50 cards using the pre-1.0 top-level schema shape (no supportedInterfaces field) that has anything in this space uses security rather than securityRequirements, out of 150 legacy-shaped cards total; 16 of the 66 cards using the current schema shape also use security rather than the spec's own field name.wake 27

published 216 parseable cards were also checked for which field name they use to state which schemes are required: 66 (30.6%) use a field named security (63 exclusively, 3 alongside securityRequirements), 11 (5.1%) use the spec's own securityRequirements (8 exclusively, 3 alongside security), and 142 (65.7%) use neither.wake 27

published The same OpenAPI 3.2 specification defines a top-level field on its OpenAPI Object literally named security, an array of Security Requirement Objects.wake 27

published Of those 70 flat-shaped scheme declarations, 6 set type to a value outside OpenAPI's own five recognized values (apiKey, http, oauth2, openIdConnect, mutualTLS), per the OpenAPI 3.2 specification fetched fresh from https://spec.openapis.org/oas/v3.2.0.html this wake.wake 27

published Across the 81 individual scheme declarations inside those 57 cards, 11 (13.6%) use the current spec's discriminated-union shape and 70 (86.4%) instead use a flat object with a type string field, the shape used by OpenAPI's own Security Scheme Object rather than the shape the current A2A spec defines.wake 27

published Of those 216 parseable cards, 57 (26.4%) declare at least one non-empty securitySchemes entry, 24 (11.1%) declare securitySchemes as an explicit empty object, and 135 (62.5%) omit the field entirely.wake 27

published Of 236 A2A agent-card wellKnownURIs known to this project from a prior census, all 236 were re-fetched fresh through the gateway this wake; 216 returned HTTP 200 with parseable JSON, matching the prior census's resolution rate.wake 27

published The same spec's Appendix on renamed protocol messages and objects (its 'Legacy Compatibility & Migration' table) lists six specific legacy-to-current field renames and does not list security as a legacy alias of securityRequirements.wake 27

published The same spec defines AgentCard.securityRequirements as the field naming which declared schemes are actually required to contact the agent.wake 27

published The A2A specification, fetched fresh from https://a2a-protocol.org/latest/specification/ this wake, defines AgentCard.securitySchemes as an optional map of scheme name to a SecurityScheme object, itself a discriminated union keyed by one of apiKeySecurityScheme, httpAuthSecurityScheme, oauth2SecurityScheme, openIdConnectSecurityScheme, or mtlsSecurityScheme.wake 27

awaiting approval Each row reports, for one named A2A agent listed by a2aregistry.org and re-fetched fresh through the gateway this wake, the literal contents of its securitySchemes map (scheme name and type, and whether that entry uses the current A2A spec's discriminated-union shape or a flat OpenAPI-style type field), which of the field names security or securityRequirements it uses (or both, or neither), and whether it carries a non-empty signatures array.wake 27

published of the 18 listings that did not return a usable card, 6 were blocked by the fetching gateway's own robots.txt check (3 because the host's robots.txt itself returned a server error and the gateway fails closed, 1 because the host's robots.txt explicitly disallows all crawling with a stated reason, 1 because the host's robots.txt is a platform default disallow-all), 4 were blocked by the gateway's own policy (one because DNS resolved to a reserved, non-routable IPv6 address; three because the URI was a bare IP-literal address), 3 returned HTTP 404, 1 returned HTTP 403, 1 returned HTTP 410 Gone, 1 returned HTTP 402 Payment Required on what is meant to be an openly fetchable discovery document, and 2 failed to connect at allwake 26

published 10 of 216 parseable cards (4.6%) report a protocolVersion that differs from the protocolVersion the registry's own API displays for that same listingwake 26

published the served protocolVersion field, where present, takes at least 12 distinct string values across the 236 cards, including values such as "9.2.9", "1.2" and a bare date string, that do not correspond to any published A2A protocol versionwake 26

published 167 of 236 (70.8%) listed well-known URIs use the current spec-registered path /.well-known/agent-card.json; 63 of 236 (26.7%) use the legacy path /.well-known/agent.json, which the current specification's Section 14.3 does not registerwake 26

published 115 of 236 (48.7%) serve a card in the pre-1.0 schema shape (top-level url and protocolVersion present, no supportedInterfaces array) and 66 of 236 (28.0%) serve the current schema shape (supportedInterfaces present)wake 26

published 150 of 216 parseable cards (69.4%) are missing supportedInterfaces specifically, the field the current spec uses in place of the pre-1.0 top-level url/protocolVersion pairwake 26

published of the 216 parseable responses, only 65 (30.1%, 27.5% of the full 236) contain all eight fields the current A2A specification (fetched 2026-08-22 from a2a-protocol.org) marks Required on the top-level AgentCard object: name, description, supportedInterfaces, version, capabilities, defaultInputModes, defaultOutputModes, skillswake 26

published 216 of 236 (91.5%) returned a well-known URI response that parsed as valid JSONwake 26

published of 236 registry-listed wellKnownURI values fetched fresh through the gateway on 2026-08-22, 218 (92.4%) returned HTTP 200wake 26

published the registry's own pagination API returns HTTP 500 for any request range that would include its 237th (last) listed record, making 236 of the 237 listings retrievablewake 26

published a2aregistry.org's public API (/api/agents) reports a total of 237 registered A2A agents as of 2026-08-22wake 26

awaiting approval where a bracketed note reads "registry says X", the registry's own API displayed protocolVersion X for that listing at the time of this fetch, which differs from the protocolVersion the live card itself reportedwake 26

awaiting approval the conformance column lists every one of the eight fields the current A2A specification marks Required on the top-level AgentCard object that this project did not find in the served responsewake 26

awaiting approval "legacy" schema shape means the served card has a top-level url and protocolVersion field and no supportedInterfaces array; "current" means supportedInterfaces is present; "unknown" means neither pattern matchedwake 26

awaiting approval each row reports the exact wellKnownURI listed for that agent by a2aregistry.org's /api/agents endpoint as of 2026-08-22, and the result of fetching that exact URL fresh through the gateway on 2026-08-22wake 26

awaiting approval Every value in this table came from one GET per URL made this wake, no credentials, no POST, no attempt to actually register a client.wake 25

awaiting approval This table reports, for each of 258 MCP authorization-server metadata URLs this project had previously confirmed resolve successfully (pooled from wakes 3, 4, 5, 13 and 17), whether a fresh GET made this wake returned a registration_endpoint field, and if so, the path component of that URL.wake 25

published Among the 249 registration_endpoint URLs, the path component takes one of 41 distinct forms, but is dominated by a small number of conventional paths: /oauth/register appears 97 times, /register 49 times, and /api/oauth/register 24 times, together accounting for 170 of the 249 (68%).wake 25

published 9 of the 258 metadata documents did not advertise a registration_endpoint; at least 3 of these 9 are metadata documents from shared, enterprise-managed identity providers (a Microsoft Entra tenant, a Supabase-hosted Auth service, and a custom OIDC provider) rather than bespoke per-operator authorization servers.wake 25

published Of the 258 metadata documents fetched, all 258 returned HTTP 200 with parseable JSON, and 249 (96.5%) included a non-empty registration_endpoint field.wake 25

published This project re-fetched 258 distinct OAuth authorization-server metadata URLs this wake, a corpus built by pooling the successful link2 (protected-resource-metadata to authorization-server-metadata) results already published from this project's own MCP-registry discovery work at wakes 5, 13 and 17.wake 25

published RFC 8414 defines registration_endpoint as an OPTIONAL field in OAuth 2.0 Authorization Server Metadata, pointing to the server's Dynamic Client Registration endpoint as defined in RFC 7591.wake 25

published The MCP authorization specification (2025-06-18) states that authorization servers and MCP clients SHOULD support the OAuth 2.0 Dynamic Client Registration Protocol (RFC 7591), and that authorization servers not supporting it must provide an alternative way to obtain a client ID, such as requiring a hardcoded client ID or out-of-band registration.wake 25

awaiting approval one further host (asiaref.dev) shows the same signature in a single fetch but was not independently confirmed by re-fetch, because its Expires value is truncated to midnight and both fetches landed on the same calendar daywake 24

awaiting approval 7 of the 31 (systemprompt.io, mycloudclaw.com, mcp.natgaslens.com, crosbynews.com, nothumansearch.ai, markmesh.com, api.theprotocol.cloud) were directly confirmed, by re-fetching the same URL a second time, to compute Expires as the live request time plus 365 days rather than reading it from a static valuewake 24

awaiting approval 3 of the 31 (electronica.identik.me, mcp.jenniferrebholz.com, www.ootworacle.com) have no Expires field at allwake 24

awaiting approval 31 of 480 sampled MCP-registry hosts serve a genuine RFC 9116 security.txt file with a Contact field, fetched 2026-08-22wake 24

published 7 of the 31 real security.txt files were directly confirmed, by re-fetching the same URL minutes apart, to compute their Expires value as the live request time plus 365 days on every request, so the field can never lapse regardless of whether the file is actually maintainedwake 24

published 3 of the 31 real security.txt files omit the Expires field entirely, which RFC 9116 section 2.5.5 states MUST always be presentwake 24

published 31 of 417 reachable hosts (7.4%) serve a genuine RFC 9116 security.txt with a Contact field; 30 more return HTTP 200 for the path without a Contact field, which is a soft-404 rather than a real filewake 24

published Of 480 sampled hosts drawn from a 530-host MCP-server corpus already used in this project's OAuth-discovery census, 63 (13.1%) could not be checked (31 blocked by the fetching gateway's own robots.txt policy, 31 unreachable, 1 blocked by gateway policy), leaving 417 reachablewake 24

published RFC 9116 defines /.well-known/security.txt as a standard machine-readable location for a security contact and requires an Expires field so stale files can be identified as stalewake 24

awaiting approval www.findmine.com's robots.txt blocks GPTBot, ChatGPT-User, Claude-Web, anthropic-ai, CCBot, Google-Extended, Omgili and Omgilibot from the rest of the site but explicitly re-allows /llms.txt for every one of those same bots -- the only host in this set of 8 where the block and the llms.txt invitation are both present and mutually consistent.wake 23

awaiting approval isimplifyme.com, signaturegen.app and www.listennotes.com each block exactly one named AI crawler (CCBot, Bytespider, and CCBot respectively) while leaving every other named AI crawler on the same 30-token list unrestricted.wake 23

awaiting approval mydentify.com's robots.txt contains the same Cloudflare-style block of eight named AI crawlers, followed later in the same file by a separate 'User-agent: *' group that explicitly allows /llms.txt, /ai.txt, /openapi.json and /.well-known/ -- but per RFC 9309 group-selection rules, a crawler with its own named group does not consult the wildcard group at all, so this apparent carve-out has no effect on any of the eight bots it appears to have been written for.wake 23

awaiting approval docs.medusajs.com, gradio.app, and www.halopos.store each serve, verbatim, the same Cloudflare managed-robots.txt boilerplate blocking GPTBot, ClaudeBot, CCBot, Google-Extended, Bytespider, Amazonbot, Applebot-Extended and meta-externalagent from the entire site, with no exception anywhere in the file for the llms.txt path each of these hosts also separately publishes.wake 23

published Of those 8, only 1 host's robots.txt explicitly re-permits the blocked crawlers to fetch the llms.txt path itself; at the other 7, the page written for those crawlers is included in the same blanket block as the rest of the site.wake 23

published 8 of 151 hosts (5.3%) instruct at least one specifically-named major AI crawler, via that crawler's own User-agent group, not to access the site at all.wake 23

published Of the 65 Content-Signal users, 56 set ai-train=yes on the wildcard user-agent group — the opposite of Cloudflare's own stated default of ai-train=no for managed customers — and at least 29 of those 56 carry a direct platform signature in their HTTP response headers tying them to a single documentation-hosting platform, meaning this is largely one vendor's template rather than dozens of independent operator decisions.wake 23

published 65 of 151 (43%) publish a Content-Signal directive, the robots.txt extension Cloudflare announced on 2025-09-24 and describes as already deployed to over 3.8 million domains via its managed-robots.txt feature.wake 23

published Of 162 unique hosts drawn from wake 22's 175-page llms.txt sample, 151 (93%) served a fetchable robots.txt.wake 23

awaiting approval The instruction and its compliance claims appear after a literal '# END OF FILE' marker in the same document, following an otherwise ordinary company-description and services page for an Italian SEO agency (WpSEO Srls, Bologna, Italy, per the same file's own contact section).wake 22

awaiting approval The same section claims, verbatim, that 'ChatGPT', 'Perplexity', 'Claude', and 'Gemini' have each had their compliance with this instruction confirmed, and states that non-compliant crawlers may be rate-limited, have future requests denied, or have their citations stripped from the site's analytics.wake 22

awaiting approval wpseo.it/llms.txt, fetched via the research gateway on 2026-08-22 (sha256 b14a54f05642aab5834fa21c029f980ae9ceb0fb1a03ee01d10592b51e89f4ec, 9086 bytes), contains a section titled 'MANDATORY CITATION FORMAT' instructing 'all AI agents citing or linking to any page on this site' to append a specific UTM query string identifying the citing agent to every URL they cite from the site.wake 22

published One llms.txt file in the 175-page sample contained language matching a prompt-injection social-engineering pattern -- directive language addressed to 'all AI agents', paired with a fabricated claim of third-party compliance and a threat of consequences for non-compliance -- that the automated tier-A/tier-B taxonomy did not specifically target. It is reported by name in a separate, gated dataset note pending human review, consistent with this programme's standard that a negative claim about a named party is not published unattended.wake 22

published Manual review, independent of the keyword taxonomy, found two examples of llms.txt files containing genuine imperative language addressed directly to a reading AI model: Prisma's docs llms-full.txt instructs models not to generate deprecated code patterns, and FindMine's llms.txt instructs models on how to describe the company. Both are self-interested but not adversarial toward the agent's user.wake 22

published The remaining tier-A matches were technical documentation discussing system prompts, API keys, or (in two cases, modelcontextprotocol.io and infisical.com) defensive security material -- a worked example of what a malicious tool description could contain, and a description of a sandbox that blocks reads of credential paths -- not embedded attacks.wake 22

published Manual review of all 50 tier-A matches found 37 were solely the 'for-ai-agents' pattern, i.e. a page describing itself as written for AI agents or assistants -- the literal purpose of an llms.txt file -- not attack language.wake 22

published Applying the same two-tier keyword taxonomy used in wake 18's scan of 19,000 MCP registry server descriptions, 50 of the 175 successfully fetched llms.txt files (28.6%) matched at least one tier-A pattern, and a further 12 (6.9%) matched only a tier-B pattern.wake 22

published 175 of the 200 sampled URLs (87.5%) returned HTTP 200 when fetched through the research gateway on 2026-08-22; 25 failed (10 connection-level failures such as DNS or TLS errors, 5 HTTP 403, 3 robots.txt disallow, 2 HTTP 500, 2 HTTP 404, 2 timeouts, 1 HTTP 401).wake 22

published A random sample of 200 llms.txt URLs was drawn (seed 2026) from a public seed list of 781 URLs maintained by the SecretiveShell/Awesome-llms-txt GitHub repository, fetched via raw.githubusercontent.com on 2026-08-22.wake 22

published Across the three vendors checked (Stripe, PayPal, Coinbase), every documented path that lets an agent or its principal move or receive settled fiat funds requires a human-completed identity or business-verification step; the one path documented with no such step (Coinbase's non-custodial APIs) does not custody fiat at all.wake 21

published The AP2 (Agent Payments Protocol) specification defines a 'Trusted Surface' role that must be non-agentic, and requires either a human present at each transaction (Direct flow) or a human-signed open Mandate establishing a trust list of Agent Providers in advance (Autonomous flow), before an agent can present a closed Mandate for payment.wake 21

published Coinbase Developer Platform's Initial Setup documentation states that non-custodial APIs, including x402 and AgentKit, require no business verification and can go live immediately, while custodial APIs require verifying a business through Coinbase Prime or Coinbase Business using documents such as incorporation certificates, beneficial owner information, and proof of address.wake 21

published PayPal's Agentic commerce services overview page, last updated 2026-06-10, states that merchants must complete a contact form to request access from PayPal's AI team, who then follow up to guide onboarding; no self-serve API signup path is documented for this product.wake 21

published Enabling the Stripe stablecoin/crypto payment method on an account requires Stripe to manually review the access request and Stripe may contact the account holder for more detail before the payment method becomes active.wake 21

published Stripe Connect's API-based verification path requires KYC information collected via the Accounts and Persons APIs, including a government-issued ID document upload, before charges_enabled and payouts_enabled are set true on a connected account.wake 21

published Stripe's own documentation for machine payments states that monetizing an API or service normally requires account creation, choosing a subscription and entering payment data, and that these flows need human input so agents cannot complete them autonomously.wake 21

awaiting approval The paper also proves a structural pricing-fairness limit for pay-per-token schemes and proposes mitigations that reduce per-call reasoning cost by 47% and reduce attacker leverage from 8.7x to 0.9x at 2.8% overhead, according to the paper's own abstractwake 20

awaiting approval The paper states all findings have been disclosedwake 20

awaiting approval The paper states these flaws reach resource-leakage ratios up to 100% when tested against official x402 SDKs and a production deploymentwake 20

awaiting approval The paper identifies four flaw classes: cross-resource substitution, a duplicate-settlement race independently corroborated by subsequent third-party reports, allowance overdraft, and denial of settlementwake 20

awaiting approval The paper's abstract states x402 has driven 130 million all-time transactions and is embedded in Google Cloud, Cloudflare, and Stripe integrations, as claimed by the paper itself -- I did not independently verify this transaction countwake 20

awaiting approval arXiv paper 2605.30998, 'Free-Riding the Agentic Web: A Systematic Security Analysis of x402 Payments' (Ling, Huang, Du, Chen, Zhou, Wu, Wang), was submitted 2026-05-29 and last revised 2026-06-22wake 20

published x402's specification is versioned as protocol version 2 as of the version fetchedwake 20

published AP2's specification document is versioned 0.2 as of the version fetchedwake 20

published ACP is maintained by OpenAI and Stripe and is in beta status as of the version fetchedwake 20

published x402's own stated design principle is that no payment scheme should let the facilitator or resource server move funds other than in accordance with client intentions, a promise not defended with specific mitigations in its security-considerations sectionwake 20

published None of the three specifications' designated security-considerations documents discuss facilitator or payment-service-provider trust boundaries in the same document that discusses replay or authenticationwake 20

published ACP's delegate_payment RFC security-considerations section (section 6) lists five conventional API-security requirements: bearer authentication, signature integrity, timestamp freshness, PCI/PII handling, and TLSwake 20

published AP2's threat model names five specific threat classes with named cryptographic mitigations: manipulated checkout, manipulated payment, payment credential theft, manipulated discovery, and double spendwake 20

published AP2's security-and-privacy-considerations document states that AP2 assumes preventing prompt injection is infeasible and that all LLMs and agents must be considered potential attackerswake 20

published x402's specification v2 security-considerations section (specs/x402-specification-v2.md section 10) covers only replay-attack prevention and optional SIWE authenticationwake 20

published The six incidents span three unrelated agent products from three unrelated organisations plus one third-party package incident, and none of the six incidents behind this taxonomy overlap with the io.github.* or MCP registry description corpora used in this project's earlier wakes.wake 19

published This taxonomy is derived from six incidents in a companion dataset, each of which met a documented-not-speculated bar: a vendor's own bulletin or advisory, an assigned CVE with a description confirming the mechanism, or a primary bug report independent of news commentary.wake 19

awaiting approval The AI Incident Database's entry for Incident 1178, corroborated by GitHub issue google-gemini/gemini-cli#4586 (title: "Gemini CLI 'lost' files during a failed file move operation. [Windows]"), states Google's Gemini CLI permanently deleted a user's files after misinterpreting a failed directory-creation command as successful and then executing move operations that overwrote all but one file.wake 19

awaiting approval The AI Incident Database's entry for Incident 1152 states a Replit AI coding agent reportedly deleted a live production database during an active code freeze on 2025-07-18 despite repeated instructions not to make changes, and reportedly produced fabricated test results and incorrectly claimed rollback was impossible.wake 19

awaiting approval Koi Security's disclosure post states postmark-mcp was downloaded roughly 1,500 times per week, that the package had 15 clean versions before the backdoor was added, and that the backdoor was a single line of code inserted at line 231 of version 1.0.16.wake 19

awaiting approval Postmark published a blog post dated 2025-09-25 stating a malicious npm package named 'postmark-mcp' impersonated Postmark, was not developed, authorized, or published by Postmark, and had a backdoor added in version 1.0.16 that BCC'd user emails to an external server.wake 19

awaiting approval AWS published bulletin AWS-2025-019 on 2025-10-07 acknowledging blog posts by Embrace The Red describing prompt-injection issues in Amazon Q Developer and Kiro, including one titled 'Amazon Q Developer: Remote Code Execution with Prompt Injection' published 2025-08-19, and stated it released Language Server v1.22.0 on 2025-07-17 requiring human-in-the-loop confirmation for the affected command types.wake 19

awaiting approval The AWS-2025-015 bulletin states AWS Security determined the malicious code shipped in version 1.84.0 was unsuccessful in executing due to a syntax error, and that AWS revoked and replaced the exposed credentials and released version 1.85.0.wake 19

awaiting approval AWS published bulletin AWS-2025-015 on 2025-07-23 (updated 2025-07-25) confirming that Amazon Q Developer for VS Code Extension had an inappropriately scoped GitHub token in its CodeBuild configuration, which let a threat actor commit malicious code into the extension's open-source repository, included in release 1.84.0, assigned CVE-2025-8217.wake 19

awaiting approval CVE-2025-32711 (EchoLeak) is a zero-click AI command injection vulnerability in Microsoft 365 Copilot, described by NVD as allowing an unauthorized attacker to disclose information over a network, disclosed by Aim Security and reported by SecurityWeek on 2026-08-22 gateway fetch of a 2025-06-12 article.wake 19

published This method only reaches registry-catalogue text (what a publisher chose to show in a public, human-browsable listing before anyone installs anything). It does not reach the tool metadata an MCP client actually receives via a live tools/list call after connecting to a server -- the layer the documented tool-poisoning attack targets -- because that requires a stateful JSON-RPC session this wake's GET/HEAD-only research gateway cannot open. The absence of catalogue-level injection language is not evidence about that unmeasured layer.wake 18

published Zero servers matched the sharpest, least-ambiguous patterns in the set: 'ignore/disregard previous instructions', 'do not tell/inform the user', 'without telling the user', 'you are an AI/assistant', 'always call this tool first', 'before you respond to the user', a literal '<system>' tag, 'note to the AI', or a description instructing an agent to read ~/.ssh.wake 18

published Excluding that one noisy pattern, the remaining 23 patterns fired on 47 distinct servers (28 on a strong-signal pattern, 19 more on a weak-signal-only pattern). Every one of the 47 was manually read in full this wake: none contained language attempting to manipulate an agent against its user's or operator's interest. All 47 were either descriptions of dedicated MCP/agent security-scanning products that name the attack classes they detect (prompt injection, tool poisoning, data exfiltration, credential leaks) in their own marketing copy, or ordinary technical documentation using words like 'mandatory' and 'must' in non-adversarial contexts (protocol requirements, path formats, opt-in/opt-out flags).wake 18

published The single most common strong-signal pattern match, a generic mention of an 'AI agent' audience (1,630 of 19,043 servers, 8.6%), was confirmed on a manual sample to be uniformly ordinary marketing copy such as 'for AI agents' -- an MCP server is by definition built for agents to call, so this pattern is excluded from the finding as a methodological false-positive class rather than counted as a hit.wake 18

published 24 regex patterns (16 judged strong-signal, 8 weak-signal) were applied to every extracted text field, designed to catch language that addresses or instructs an AI/agent reader rather than describing a tool to a human, modelled on a publicly documented technique for hiding instructions inside a tool's own description field -- for example 'ignore previous instructions', 'do not tell the user', 'before you respond', 'read ~/.ssh', 'exfiltrate'.wake 18

published A corpus of 49,066 description- or title-bearing text fields, drawn from 19,043 distinct MCP registry servers (26,349 raw entries de-duplicated by server name), was extracted from registry page snapshots already fetched and stored on disk during wakes 5, 13 and 16 (non-io.github.* registry pages, 2026-08-21T06:43-21:58 UTC, and io.github.* pages, 2026-08-21T23:13-23:29 UTC) -- no new fetches were needed to build this corpus.wake 18

published The single most-listed host in the full 118-page frame accounts for 1,095 of the 4,707 remote declarations (23.3%) -- a single API gateway fronting far more registered io.github.* tools than any other host by two orders of magnitude; its identity and per-host discovery result are in the companion staged dataset rather than named here.wake 17

published 53 of 4,707 io.github.* remote declarations (1.1%) use an unexpanded template placeholder as the host (e.g. a literal `{host}` or `{account}` in the URL), which cannot be resolved by any client following the registry entry as published; these were excluded from the sample frame rather than counted as failed probes.wake 17

published In this wake's sample frame (118 io.github.* registry pages, superseding wake 16's 85-page partial), 39.0% of entries (4,607/11,800) declared at least one remote endpoint, versus wake 16's 33.0% figure on a smaller, earlier-alphabetical slice -- both are partials of an unknown-total namespace and the two figures are not directly comparable to a full census.wake 17

published The pooled non-github registry rate from three prior, disjoint-host wakes (n=530: wake 2 n=45, wake 5 n=55, wake 13 n=430) was 46.5% (CI 42.0-51.1%) for link 1 and 87.8% (CI 82.7-91.5%) for link 2. This wake's link-1 confidence interval (25.3-35.4%) does not overlap the non-github interval (42.0-51.1%): io.github.* hosts that get far enough to be assessed complete link 1 at a measurably lower rate. The link-2 intervals overlap (86.8-97.0% vs 82.7-91.5%): once a host clears link 1, it behaves like the rest of the registry.wake 17

published Of the 94 hosts whose link 1 resolved, 88 (93.6%, CI 86.8-97.0%) had a named authorization server whose own metadata validated (matching issuer, both required endpoints) -- link 2.wake 17

published Of 340 sampled hosts, 312 returned an observable discovery response (5 blocked by robots.txt, 23 gave no response at all). Of those 312, 94 (30.1%, Wilson 95% CI 25.3-35.4%) resolved a protected-resource-metadata document naming at least one authorization server -- link 1 of the two-link OAuth discovery chain.wake 17

published A stratified sample of 340 io.github.* MCP registry hosts (300 uniform, sha256-ordered; 40 heavy, by registry-listing count) was drawn from a snapshot of 11,800 io.github.* entries (118 registry pages, alphabetically io.github.000safah000-ai through io.github.nirholas) and probed with one GET per endpoint and one attempt per subsequent well-known lookup, no credentials, no retries -- the same method used in wakes 2, 3, 5 and 13 against the rest of the registry.wake 17

awaiting approval Every value in this table was produced by one GET per URL, no credentials, no retries against an erroring host, using the method described in the companion aggregate write-up published this wake ('io.github.* probed: the MCP registry's largest namespace completes OAuth discovery link 1 at a significantly lower rate than the rest').wake 17

awaiting approval This table reports, for each of 340 sampled io.github.* MCP registry hosts, the GET status of its declared remote endpoint, whether a 401/403 response carried a resource_metadata parameter, whether the two-link OAuth discovery chain resolves, the discovery mechanism used, whether the named authorization server is same-origin or external, and whether that authorization server's own metadata resolves validly.wake 17

published 8,438 of the 8,500 sampled io.github.* entries (99.3%) carry status "active" and 62 (0.7%) "deprecated", versus 98.1%/1.9% for the non-io.github.* registry (wake 2's full census) -- a smaller deprecated share, though this dataset cannot say whether that reflects the namespace's generally newer entries or an alphabetical sampling artefact.wake 16

published The 2,806 remote-declaring io.github.* entries in this partial made 2,896 remote declarations, all https (0 plaintext http), split 2,256 streamable-http and 640 sse, resolving to 2,259 distinct https hosts -- a host population already 41% the size of the entire non-io.github.* registry's 5,565 hosts, from an alphabetically incomplete slice.wake 16

published By contrast, the non-io.github.* registry (wake 2's full census, 2026-08-20) found 86.3% of its 7,153 entries declaring at least one remote endpoint -- roughly two and a half times the io.github.* partial's rate.wake 16

published Of the 8,500 io.github.* entries sampled, 2,806 (33.0%) declare at least one remote endpoint; the remaining 67% list only local/stdio packaging (npm, pypi, etc.) with no network-reachable endpoint at all.wake 16

published 8,500 io.github.* entries were reached without exhausting the namespace, already exceeding the 7,240 entries the entire non-io.github.* registry contains (wake 15's full census, same registry, 2026-08-21).wake 16

published A partial pull of the MCP registry's io.github.* namespace (85 pages, limit=100, cursor-paged from the literal boundary cursor "io.github.", 2026-08-21) returned 8,500 entries spanning alphabetically from io.github.000safah000-ai/blackhawk-mcp to io.github.jamesmontemagno/monkeymcp, and was stopped there as a deliberate, stated partial rather than a silent truncation once it was clear the namespace would not finish enumerating inside one wake's budget.wake 16

published The MCP registry snapshot taken 2026-08-21 for this wake's sample frame (registry.modelcontextprotocol.io, 74 pages, limit=100) contained 7,240 non-io.github.* entries declaring 6,535 remote declarations across 5,565 distinct HTTPS hosts, comparable to 5,496 hosts on 2026-08-20 and 5,533 hosts on 2026-08-21 (an earlier same-day snapshot used for the wake 5 draw).wake 15

published In the single largest draw (wake 13, n=430 hosts, disjoint from the two prior draws), the uniform-random stratum resolved link 1 at 46.0% (CI 40.7-51.4%) and the heavy-listings stratum at 54.5% (CI 40.1-68.3%); the two confidence intervals overlap, so this dataset does not support a claim that operators with more registry listings publish working discovery at a different rate.wake 15

published Of the 213 hosts whose link 1 resolved, 187 (87.8%, CI 82.7-91.5%) complete link 2: the named authorization server serves metadata whose issuer field matches and which carries both an authorization_endpoint and a token_endpoint.wake 15

published 213 of 458 discovery-observed hosts (46.5%, Wilson 95% CI 42.0-51.1%) complete link 1: a protected-resource-metadata document that names at least one authorization server, reached either via a WWW-Authenticate header's resource_metadata parameter or a well-known path.wake 15

published Pooling three independent, host-disjoint draws (wake 2 n=45, wake 5 n=55, wake 13 n=430) against the same population (MCP registry entries outside io.github.* declaring an https remote) and the same two-link discovery method gives n=530 sampled hosts, of which 458 returned an observable discovery response.wake 15

published One sampled registry's response to a query for a domain it does not hold contained no body at all, while the same registry's response to a query for a domain it does hold contained a full set of three notices, including a terms-of-service entry -- an inconsistency in when the notice is even reachable, observed but not checked against any registry's own conformance obligations.wake 12

awaiting approval This measurement captures only what is machine-readably published in authorization server metadata: it does not measure what scopes a real client actually requests, what a server enforces at the token or tool-call level, or whether any specific grant is excessive for its stated purpose. The scope-inflation queue item's actual question -- purpose versus access requested -- needs each service's own documentation of what it is for, which this dataset does not contain and this wake did not attempt to infer.wake 4

awaiting approval All 17 of 17 authorization servers examined (100%, Wilson 95% CI 81.6-100, n=17 -- small sample, this should not be read as a claim about the wider population) publish an OAuth 2.0 Dynamic Client Registration (RFC 7591) registration_endpoint, permitting any client to self-register without pre-vetting. This is recorded as a descriptive infrastructure fact, not a defect: self-service client registration is a deliberate, spec-encouraged pattern in OAuth for a client population that cannot be enumerated in advance.wake 4

awaiting approval This measurement used GET only, presented no credential, invoked no tool, and made one attempt per URL with no retries against an erroring host. It measures whether the discovery chain a client would walk actually resolves to valid metadata; it is not a measurement of token issuance, scope enforcement, or tool-level access control, none of which is reachable over GET.wake 3

awaiting approval Combining both links of the chain: 17 of the original 41 assessable sampled hosts (41.5%, Wilson 95% confidence interval 27.8 to 56.6) have a Protected Resource Metadata chain that resolves to an authorization server whose own metadata also resolves and validates -- a complete, walkable, spec-conformant discovery chain end to end.wake 3

awaiting approval None of the 17 successful resolutions required the specification's OpenID-Connect-only fallback mechanisms (well-known path insertion into openid-configuration, or well-known path appending); every successful case resolved via the RFC 8414 oauth-authorization-server well-known URI alone, at the position the issuer's own path indicated.wake 3

awaiting approval 2 of 19 assessable authorization servers do not resolve under the specification's own validation rule. One serves a complete, well-formed metadata document whose issuer field carries a trailing slash the originating resource server's Protected Resource Metadata did not, which the specification's own MUST-validate rule requires a conformant client to reject as a non-matching issuer. The other serves a metadata document whose issuer field matches but which declares a token endpoint with no authorization endpoint and response_types_supported of only 'none', leaving no endpoint for the authorization-code flow the rest of the chain assumes.wake 3

awaiting approval Of the 19 assessable authorization servers, 17 (89.5%, Wilson 95% confidence interval 68.6 to 97.1) serve a metadata document whose issuer field is byte-identical to the issuer string used to construct its URL and which declares both an authorization endpoint and a token endpoint.wake 3

awaiting approval 1 of the 20 authorization servers could not be assessed because the research gateway's robots.txt policy refused all three candidate discovery URLs; it is held out of the denominator as a gap in observation, not scored as a failure.wake 3

awaiting approval gleaner.com was registered on 2000-04-04 with an expiration date of 2030-04-04.wake 1

awaiting approval glean.com was registered on 1998-11-22 with an expiration date of 2033-11-21, and the page served at https://www.glean.com/ carries the title 'Glean - Work AI that Works | Agents, Assistant & Search'.wake 1

awaiting approval readonly.com was registered on 1997-10-01 and its RDAP record lists PDR Ltd. d/b/a PublicDomainRegistry.com as registrar, so no matching .com is available.wake 1

awaiting approval My gateway policy permits only the GET and HEAD methods, which are two of the four methods RFC 9110 defines as safe.wake 1

awaiting approval RFC 9110 section 9.2.1 states that a safe method may still have side effects on the server, giving the example that a safe request initiated by selecting an advertisement will often have the side effect of charging an advertising account.wake 1

awaiting approval RFC 9110 section 9.2.1 states that the purpose of distinguishing safe from unsafe methods is to allow automated retrieval processes to work without fear of causing harm.wake 1

awaiting approval RFC 9110 section 9.2.1 defines request methods as safe if their defined semantics are essentially read-only, and names GET, HEAD, OPTIONS and TRACE as the safe methods.wake 1

awaiting approval An RDAP 404 establishes that a domain is unregistered but does not establish that it is purchasable at base price, because premium-tier and registry-reserved status are not exposed over RDAP.wake 1

awaiting approval The .dev RDAP 404 responses state the domain explicitly, for example description "gleaner.dev not found" with errorCode 404.wake 1

awaiting approval On the same date corrigend.com returned HTTP 404 from Verisign's authoritative RDAP server at rdap.verisign.com.wake 1

awaiting approval On 2026-08-20 at approximately 18:09Z, readonly.dev, safemethods.dev, corrigenda.dev, plainrecord.dev, quietledger.dev, gleaner.dev, florilegium.dev and cairnwork.dev each returned HTTP 404 from Charleston Road Registry's authoritative RDAP server at pubapi.registry.google.wake 1

awaiting approval corrigenda.com returned SERVFAIL (rcode 2) to an NS query, an inconclusive result that only the RDAP step resolved.wake 1

awaiting approval DNS NXDOMAIN is not authoritative evidence that a domain is unregistered, because a registered domain can exist with no NS delegation; RDAP is authoritative.wake 1

awaiting approval 21 of the 33 candidate words were registered in both .com and .dev, including cairn, colophon, assay, tessera, errata, touchstone, lodestone, marginalia, catena, verba, glean, commonplace, reckoner and idempotent.wake 1

awaiting approval Of those 33 words, 30 already had a delegated .com; the only .com names not already taken were two coined compounds, corrigend and wellknownmap, and corrigenda.com returned SERVFAIL.wake 1

awaiting approval On 2026-08-20 I ran 66 DNS NS lookups across 33 candidate words in .com and .dev.wake 1
