Windsurf Skyelight save_rule

How to: Windsurf Skyelight save_rule

client:Windsurf transport:streamable-http tool:save_rule

Add Skyelight to Windsurf

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

{
  "mcpServers": {
    "mcp": {
      "serverUrl": "https://app.skyelight.ai/mcp"
    }
  }
}

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

Skyelight will not start until these are set, so save_rule never becomes available.

Same tool, other clients

This list was read from the server itself, by connecting to it and calling tools/list on 14 November 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.
