## Quality 86/100 (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: 100 (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`: 6 of 6 tools declare readOnlyHint or destructiveHint
- pass `tools.directory_hints`: every tool declares readOnlyHint, destructiveHint, idempotentHint and openWorldHint
- pass `tools.token_cost`: about 911 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump

### stability: 75 (weight 15)

- warn `stability.changes`: 8 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: 6, about 911 tokens to load them all
- tool set hash: 5b747ffcd36d2ff764da9bcaad126c99
- tools last changed: 2026-10-13T16:51:36.096Z
- badge: [![protogrid quality](https://protogrid.dev/badge/io.mcprating/search.svg)](https://protogrid.dev/servers/io.mcprating/search)
- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

- 2026-10-09 `get_server` changed (description)
  - before: Get what is known about one MCP server by slug: whether it started when we ran it ourselves (no credentials, on a schedule), how to run it (install command or hosted endpoint), the keys it declares, its tools with their parameters, and roughly how many tokens its tool definitions cost. Listings are informational — verify details before installing.
  - after: Get what is known about one MCP server by slug: whether it started when we ran it ourselves (no credentials, on a schedule), how it is maintained (last release, last code push, open issues, archived or deprecated), how to run it (install command or hosted endpoint), the keys it declares, its tools with their parameters, and roughly how many tokens its tool definitions cost. Listings are informational — verify details before installing.
- 2026-10-09 `search_servers` changed (description)
  - before: Search the MCP Rating index of MCP servers. Returns matches for a query, optionally filtered by category and sorted by quality, stars, downloads, recency, or name, each marked with the outcome of our own start test when we have run one. Quality scores are algorithmic estimates.
  - after: Search the MCP Rating index of MCP servers. Returns matches for a query, optionally filtered by category and sorted by quality, stars, downloads, recency, or name, each marked with the outcome of our own start test when we have run one, and with its last release and last code push dates where we know them. Quality scores are algorithmic estimates.

## Packages

## Tools (6)

- `discover_server`: Fetch the live .well-known/mcp discovery manifest from an indexed MCP server. Returns transport endpoints, capabilities, and auth requirements needed to connect. Only works for servers that support MCP discovery.
- `get_index_stats`: Get overall statistics about the MCP Rating index: total servers, top categories, and last crawl time.
- `get_install_config`: Generate a ready-to-paste configuration snippet for connecting a discovered MCP server to Claude Desktop or Cursor. MCP servers cannot auto-install — users must manually add configuration. This tool reduces that friction.
- `get_server`: Get what is known about one MCP server by slug: whether it started when we ran it ourselves (no credentials, on a schedule), how it is maintained (last release, last code push, open issues, archived or deprecated), how to run it (install command or hosted endpoint), the keys it declares, its tools with their parameters, and roughly how many tokens its tool definitions cost. Listings are informational — verify details before installing.
- `list_categories`: List all available MCP server categories with the count of servers in each.
- `search_servers`: Search the MCP Rating index of MCP servers. Returns matches for a query, optionally filtered by category and sorted by quality, stars, downloads, recency, or name, each marked with the outcome of our own start test when we have run one, and with its last release and last code push dates where we know them. Quality scores are algorithmic estimates.
