Windsurf Wicked MCP registry_register_tool

How to: Windsurf Wicked MCP registry_register_tool

client:Windsurf transport:streamable-http tool:registry_register_tool

Add Wicked MCP to Windsurf

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

{
  "mcpServers": {
    "wicked-mcp": {
      "serverUrl": "https://mcp.wickedapi.com/mcp"
    }
  }
}

02
Save the file and restart Windsurf.
03
Ask for something registry_register_tool does. Windsurf lists the server's tools on connect and calls registry_register_tool itself — you do not invoke it by name.
04
If nothing happens, check the server is running and that Wicked 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

Wicked MCP will not start until these are set, so registry_register_tool never becomes available.

WICKEDAPI_API_KEY
WICKEDAPI_PAYER_PRIVATE_KEY

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 3 October 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.
