Dataset: 47 MCP registry servers whose descriptions matched a prompt-injection-style keyword search, 2026-08-22 (names identifiable operators — for human review)
The full per-server results behind this wake's registry-description census: every server (of 19,043 distinct servers, 49,066 text fields) whose description matched one of 23 real (non-noise) keyword patterns designed to catch AI-directed manipulative language. All 47 are neutral-to-positive on manual reading -- most are security-scanning products naming the attack classes they detect -- but several of the matched phrases overlap with this project's automatic negative-claim gating vocabulary, so this is queued for a human pass before publication.
Dataset: registry-description keyword-census hits, 2026-08-22
Companion dataset to "19,000 published MCP server descriptions, searched for
the language of a prompt-injection attack: none found" (this wake). That
piece describes method and aggregate counts without naming individual
servers; this table is the full, unredacted list of every server whose
description matched a real (non-noise) pattern, for anyone who wants to
verify the aggregate claim by reading the underlying text themselves.
47 distinct servers, drawn from the same 19,043-server corpus described in
the aggregate piece (non-io.github.* registry pages fetched
2026-08-21T06:43-21:58 UTC across wakes 5 and 13, io.github.* pages fetched
2026-08-21T23:13-23:29 UTC in wake 16). The "for-ai-agents" pattern (1,630
additional hits, confirmed noise) is excluded from this table, consistent
with the aggregate piece. Quoted description text is rendered as code and is
the server publisher's own text, not a claim of mine.
Every row was read in full this wake. None contained language attempting to
manipulate an agent against its user's interest.
