Tools

Tool	Description	Behaviour
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.	Not declared
get_index_stats	Get overall statistics about the MCP Rating index: total servers, top categories, and last crawl time.	Not declared
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.	Not declared
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 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.	Not declared
list_categories	List all available MCP server categories with the count of servers in each.	Not declared
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. Quality scores are algorithmic estimates.	Not declared
