Windsurf Claidex MCP query_package_registry

How to: Windsurf Claidex MCP query_package_registry

client:Windsurf transport:streamable-http tool:query_package_registry

Add Claidex MCP to Windsurf

01
Open ~/.codeium/windsurf/mcp_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "failure-intelligence": {
      "serverUrl": "https://app.claidex.com/api/mcp"
    }
  }
}

02
Save the file and restart Windsurf.
03
Ask for something query_package_registry does. Windsurf lists the server's tools on connect and calls query_package_registry itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that Claidex MCP's identifier in your config matches the one above exactly.

Global only — Windsurf has no per-project MCP config. Refresh Cascade after saving. Windsurf docs

Set these first

Claidex MCP will not start until these are set, so query_package_registry never becomes available.

CLAIDEX_MCP_URL
CLAIDEX_MCP_API_KEY

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 24 September 2026. It is what the server actually exposes, not what its listing claims.

Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
