## FAQ

### How do I authenticate the Timebook MCP server?

Run `timebook login` in your terminal once to authenticate via your browser; the MCP server will then reuse the saved token.

### Can the AI delete or edit my time entries?

Yes, but an API token can only modify or delete entries that it created itself; invoiced entries are locked.
