The MCP Google Email Service implements a Gmail-based email service using the Model Context Protocol. It provides a standardized interface for Gmail integration across applications, reducing boilerplate when interfacing with Gmail API. It supports flexible authentication methods: Service Account via GOOGLE_APPLICATION_CREDENTIALS or GOOGLE_CREDENTIALS_CONFIG, OAuth 2.0 using credentials.json and token.json, and Application Default Credentials. It supports environment-based configuration via environment variables, making it suitable for development, staging, and production. The service leverages MCP to provide consistent context and state management across MCP-compliant services, enabling scalable integration with other MCP components. Core capabilities include sending and receiving emails, listing messages with search capability, replying to messages, and retrieving today's messages. Usage examples demonstrate initializing FastMCP("GMail"), listing unread messages, sending messages, retrieving today's messages, and replying to messages. Requirements include Python 3.11+, google-api-python-client, google-auth-httplib2, google-auth-oauthlib, mcp, pydantic, and python-dotenv. This design supports automated email handling, Gmail functionality integration, logging, and real-time email processing in contexts such as LLM-enabled applications.
