feat(mcp): send the client's identity on lookups and grade requests#91
Merged
Conversation
The lookup tools called polygraph.so anonymously; only request_grade carried the caller's name/version. Now all three (check_server, list_servers, request_grade) attribute the connected client, so polygraph.so's aggregate per-agent usage counters see MCP clients as themselves rather than as a generic runtime User-Agent. - client-id.ts: clientAgent(server) — name/version plus whatever the initialize handshake declared (title, websiteUrl, description, capability keys such as sampling/roots). Software metadata only; nothing about the user is read or sent. - api.ts: postCheck/postGradeRequest carry source/agent_id/agent_meta in the body; getList via query params. - both servers bind the tool handlers with the connected client's identity, as request_grade already did. All fields are optional server-side — older deployments ignore them.
