Server Details

Grade MCP servers A to F with the open behavioral litmus. npm: full toolset; hosted: lookups only.

The last two health checks of this connector failed. If this server requires authentication, missing or expired test credentials may be the cause. A test profile lets Glama authenticate for health checks and discover tools; it is separate from your personal connections.

If you are the author, claim ownership, then add or update a test profile under Admin → Test Profile.

TDQS

A4.6/5.0

Scored across 3 tools

Disambiguation5/5

Each tool has a distinct purpose: check_server queries a single server's grade, list_servers lists graded servers, and request_grade is a discontinued stub that clearly informs the user. There is no overlap or ambiguity between them.

Naming Consistency5/5

All three tools follow a consistent verb_noun pattern (check_server, list_servers, request_grade), making the API predictable and easy to reason about.

Tool Count5/5

With exactly three tools, the server is well-scoped for a read-only grading service. Each tool earns its place, and the count is neither too sparse nor bloated.

Completeness5/5

The domain is querying published server grades, and the set covers checking individual servers, listing all graded servers, and gracefully handling the discontinued request path. No essential operations are missing for the intended use case.

    Launches any MCP server as a real client would, running the handshake, inspecting every tool's schema and description, and deliberately making a bad tool call to test error handling. Returns one deterministic, evidence-backed score with named issues so servers can be verified before users' agents hit them in production.
