Build Preflight

If you haven’t already, clone and build the server:
git clone https://github.com/EthanAckerman-git/Preflight.git
cd Preflight
npm install
npm run build
2

Edit the MCP config file

Open ~/.codeium/windsurf/mcp_config.json, creating it if it doesn’t exist, and add the Preflight entry:
{
  "mcpServers": {
    "preflight": {
      "command": "node",
      "args": ["/path/to/Preflight/dist/index.js"],
      "env": {
        "PATH": "/opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin"
      }
    }
  }
}
Replace /path/to/Preflight/dist/index.js with the absolute path to the built server on your machine.
If you installed idb via pip, add your Python bin directory to PATH. For example: /opt/homebrew/bin:/usr/local/bin:/usr/bin:/bin:~/Library/Python/3.x/bin

Verify in Windsurf

  2. Open Settings → Cascade → MCP.
