## Quality 88/100 (good)

### protocol: 75 (weight 25)

- warn `protocol.modern`: newest supported version is 2025-11-25; 2026-07-28 not supported, older versions are deprecated until 2027-07-28
- n/a `protocol.stateless`: only applies to 2026-07-28 servers
- pass `protocol.transport`: streamable HTTP
- n/a `protocol.list_ttl`: only applies to 2026-07-28 servers

### authorization: n/a (weight 15)

- n/a `auth.prm`, `auth.as_metadata`, `auth.cimd`: no remote uses OAuth
- 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
- pass `tools.annotations`: 3 of 3 tools declare readOnlyHint or destructiveHint
- warn `tools.directory_hints`: 1 of 3 tools declare all four hints; missing: search_servers (destructiveHint, idempotentHint); get_server (destructiveHint, idempotentHint)
- pass `tools.token_cost`: about 926 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: 3, about 926 tokens to load them all
- tool set hash: 5524a18c9648e21ece1f1c8142b33c9a

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

## Tools (3)

- `get_server`: Get one server by its exact name: its server.json manifest, its review status, and ready-to-use install snippets. Use it to check on a server you submitted; status is pending until a maintainer approves it.
- `search_servers`: Search the registry for MCP servers. Matches names, titles, descriptions, tags and the names of the tools each server exposes. Returns short summaries; call get_server for install instructions. Search before submit_server so you don't add a duplicate.
- `submit_server`: Add an MCP server to the registry. New submissions are reviewed by a maintainer before they appear in search; get_server shows their status meanwhile. Fill in what you know from the server's README or package metadata. If the result is an error, fix the fields it names and call again. Never include secrets: env_vars takes variable names only, not values.
