MCP QUEEN

The Graded Registry

Every remote server in the official MCP registry, probed live and graded with receipts β€” the only MCP index where every grade shows its evidence.

Methodology

Each server is probed live over streamable HTTP: reachability (25) β€” does initialize succeed; auth-gated servers earn partial credit only if they advertise WWW-Authenticate so clients can discover OAuth. protocol (15) β€” valid JSON-RPC handshake; deprecated SSE transport is penalized. tooling (35) β€” tools/list works, share of tools with descriptions and fully-typed input schemas, median description depth. latency (10) β€” initialize round-trip. provenance (15) β€” registry metadata completeness and whether the reverse-DNS namespace actually matches the serving domain. Scores scale to what is verifiable; unverifiable dimensions mark the grade provisional rather than guessing. Every point carries the verbatim observation that earned it. No stars, no votes, no pay-to-rank β€” probes only.
