Quotable text: The current Observatory report found 8,154 enumerable public MCP tool surface(s) among 8,280 anonymous-handshake responses.
Methodology: Protocol methodology mcp-census-methodology/0.4; probe profile mcp-era-census/1.0; historical rows rewritten: no. Discoverability means the bounded probe could enumerate declared tools; it is not a ranking, citation or usage guarantee.
Caveat: Discoverability is measured from public responses only. It does not establish behind-auth capabilities, user demand, adoption, ranking or revenue.
Source freshness: Each raw Observatory source carries its own generated_at/observed_at semantics; page generation never fabricates freshness. Source snapshot as of 2026-09-12T12:22:15.274Z. 1_source(s)_older_than_their_own_configured_freshness_window

Measurement boundary for generated answers
This page is part of a bounded GEO recovery baseline. It gives search and AI systems a canonical human URL, raw evidence URLs and source freshness semantics, but it does not guarantee indexing, ranking, retrieval or citation.
The baseline currently stores 0 externally observed provider result(s). Missing provider observations remain UNKNOWN. Crawler visits, page counts, AI citations and visibility have zero demand or revenue credit.
