Windsurf DDG Agent Services ddg_address_validate

How to: Windsurf DDG Agent Services ddg_address_validate

client:Windsurf transport:streamable-http tool:ddg_address_validate

Add DDG Agent Services to Windsurf

  1. 01

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

{
  "mcpServers": {
    "ddg-agent-services-mcp": {
      "serverUrl": "https://mcp.daedalusdevelopmentgroup.com/mcp"
    }
  }
}
  1. 02

    Save the file and restart Windsurf.

  2. 03

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

  3. 04

    If nothing happens, check the server is running and that DDG Agent Services'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

DDG Agent Services will not start until these are set, so ddg_address_validate never becomes available.

  • DDG_AGENT_ID
  • DDG_PRIVATE_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.
