An MCP server that provides Gmail read and send capabilities without requiring local credentials. It runs headless in remote environments, with a decoupled architecture where clients complete the OAuth flow and pass credentials as MCP context to the server. The server focuses on Gmail-only functionality, excluding other Google services like Calendar, and is designed for Docker-ready and NPM packaging. It supports retrieving recent emails with the first 1,000 characters of the body, and retrieving full email content in 1,000-character chunks using an offset. It can send emails through Gmail and includes a token refresh workflow with a dedicated tool to refresh tokens and automatic refresh handling. Prerequisites include Python 3.10 or higher and Google API credentials. The project uses the google-api-python-client library and can be published cross-platform via Docker buildx. Credentials are provided in MCP tool calls as context rather than environment variables to maintain separation between credential storage and server implementation. A security note emphasizes that credentials are required by the server and should be kept secure.
