## Quality 92/100 (strong)
### protocol: n/a (weight 25)
- n/a `protocol.modern`, `protocol.stateless`, `protocol.transport`, `protocol.list_ttl`: no remote answered a protocol handshake (not probed yet, unreachable, or local-only)
### authorization: 83 (weight 15)
- pass `auth.prm`: Protected Resource Metadata (RFC 9728) published
- pass `auth.as_metadata`: authorization server metadata reachable
- warn `auth.cimd`: only Dynamic Client Registration, deprecated in 2026-07-28 in favour of CIMD
- n/a `auth.secret_in_url`: no templated URL
### tool hygiene: 93 (weight 30)
- pass `tools.descriptions`: every tool has a description
- pass `tools.description_length`: descriptions are concise
- pass `tools.schemas`: every tool has an object input schema

- warn `tools.directory_hints`: 25 of 26 tools declare all four hints; missing: get_status (destructiveHint, idempotentHint)
- pass `tools.token_cost`: about 6,209 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
### stability: 100 (weight 15)
- pass `stability.changes`: no tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
### dependencies: n/a (weight 15)
- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package
- tools: 26, about 6,209 tokens to load them all
- tool set hash: 6a1c608bd54fa3eb127690dfe8a020d8
- badge: [](https://protogrid.dev/servers/com.cofferdock/cofferdock)
