Windsurf Arclan MCP Registry query_registry

How to: Windsurf Arclan MCP Registry query_registry

client:Windsurf transport:streamable-http tool:query_registry

Add Arclan MCP Registry to Windsurf

  1. 01

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

{
  "mcpServers": {
    "registry": {
      "serverUrl": "https://arclan.ai/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

    Ask for something query_registry does. Windsurf lists the server's tools on connect and calls query_registry itself — you do not invoke it by name.

  3. 04

    If nothing happens, check the server is running and that Arclan MCP Registry'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

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.
