MCP Rating MCP server

• discover_serverFree

  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_statsFree

  Get overall statistics about the MCP Rating index: total servers, top categories, and last crawl time.

• get_install_configFree

  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_serverFree

  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.

• list_categoriesFree

  List all available MCP server categories with the count of servers in each.

• search_serversFree

  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.
