Skills

census_lookup

Get the live health verdict for one MCP server by its exact registry name (e.g. 'io.github.owner/name'). Returns stars, last-push recency, gone/archived/deprecated flags, name-collision count, and a fact-based health verdict (healthy | issues | unknown).

census_search

Search MCP servers by keyword or partial name (e.g. 'github', 'postgres'). Returns up to 20 matches ranked by GitHub stars, each with its health verdict. Use before choosing an MCP server to depend on.
