Q: What is MCP (Model Context Protocol)? A: MCP is an open protocol that standardizes how applications provide context to Large Language Models (LLMs).

Q: How do I authenticate with Google for the Gmail MCP Server? A: You need to enable the Gmail API and Google Calendar API in your Google Cloud Platform project, configure the OAuth consent screen, create OAuth 2.0 credentials, and add your email as a test user.

Q: How do I configure Claude Desktop to use the Gmail MCP Server?

Check that the token file exists, verify your Google Cloud Console project has the correct redirect URI, and ensure that all required scopes are added to your OAuth consent screen. Double check the Client ID and Secret.

Q: What if I have issues with the Calendar API? A: Make sure you’ve enabled the Calendar API in Google Cloud Console, granted all the necessary scopes during authentication, and that CALENDAR_API_ENABLED is set to true in your environment variables. You may need to re-authenticate by deleting tokens.json.
