   node src/index.js --token <your_token> --api-base-url https://app.plainsignal.com/api/v1

2. Set the API_BASE_URL environment variable:

   export API_BASE_URL=https://app.plainsignal.com/api/v1

3. Pass a custom API base URL to the constructor when instantiating the server programmatically:

   const server = new PlainSignalStdioServer(token, 'https://app.plainsignal.com/api/v1');

For Developers
