Windsurf

​

Install Steps

1. Open the mcp_config.json file. This can be found at a path like ~/.codium/windsurf/mcp_config.json or by opening Cascade Chat and clicking the Customizations icon (looks like a packing box) in the top right then clicking the settings button.
2. Update mcp_config.json as follows:

{
  "mcpServers": {
    "Ref": {
      "command": "npx",
      "args": ["ref-tools-mcp@latest"],
      "env": {
        "REF_API_KEY": "<YOUR_API_KEY>"
      }
    }
  }
}
