Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (5)

get_dataset_infoDataset metadata: entry counts, generation timestamp, source, and licensing terms for bulk or training use.
get_serverGet the full directory entry for one MCP server by id ('owner--repo', e.g. 'microsoft--playwright-mcp'). Includes install hint, license, stars, category, and editorial fields. Any install_hint is a best-effort guess from the repository language, not a verified command: relay the install_hint_caveat with it rather than presenting it as ready to run.
list_categoriesList all directory categories with slugs, names, and active-server counts.
list_topicsList the curated GitHub topics that have a directory page, with active-server counts. Topics are assigned by repository owners and imported verbatim, so the full dataset carries thousands of them; this returns only the curated subset. search_servers accepts any topic string, curated or not.
search_serversSearch the MCP server directory by keyword and/or filters. Keyword matches name, description, and GitHub topics. Returns active servers sorted by relevance then stars. Supply at least one of query, category, or topic — with no query, filters alone enumerate a whole category or topic by stars. Data refreshes nightly from the public GitHub API. Any install_hint is a best-effort guess from the repository language, not a verified command: relay the install_hint_caveat with it rather than presenting it as ready to run.

Schemas: list_tools.
