Frequently asked questions

How do I set up the Google Calendar API?

Create a project in the Google Cloud Console, enable the Google Calendar API, generate OAuth 2.0 credentials (web application), and set the redirect URI to `http://localhost:3000/oauth2callback`.

How do I fix "Permission denied" errors?

Use the built-in launcher (`node -e "require('child_process').spawn(...)"`) that does not rely on executable permissions, or manually fix permissions with `chmod`.

Delete the token file at `~/.mcp-google-calendar/token.json` and re-authenticate on the next run.

How do I run the server in debug mode?

Set the `DEBUG` environment variable to `true` when starting the server.

Node.js 16.x or higher is required.
