"Gmail MCP server" splits three ways: community OSS repos you self-host (GongRzhe, taylorwilsdon, shinzo-labs), Anthropic's first-party Gmail connector inside Claude.

"IMAP MCP server" is the catch-all for self-hosted connectors that speak IMAP/SMTP — anything from Gmail to ProtonMail Bridge to your own mail server.

Make.
