FAQ from Gmail IMAP MCP Server
How do I authenticate a Gmail account?
Use the authenticate-gmail tool with your email address. An OAuth2 flow will open in your browser; after granting permission, the server stores the token for future sessions.
What are the prerequisites?
Python 3.12 or higher, a Google Cloud Project with the Gmail API enabled, and OAuth 2.0 Client ID credentials (download as client_secret.json).
How do I start the server and connect it to Claude Desktop?
Run python -m gmail_imap_mcp.server to start the server. Then in Claude Desktop, navigate to Settings and configure the MCP server endpoint.
Where are credentials stored?
OAuth credentials and tokens are stored in ~/.gmail_imap_mcp_credentials/ — separate token files per account (format token_{email}.json). This location is user‑specific and persists across sessions.
What is the email ID format?
Email IDs follow the pattern email://message/{account}_{mailbox}_{id}, where account is the Gmail address, mailbox is the label, and id is the IMAP unique ID.
