Gmail MCP Server

A Model Context Protocol (MCP) server for Gmail integration, built with FastMCP. This server provides AI assistants with the ability to interact with Gmail through a set of standardized tools.

Overview

This project implements an MCP server that allows AI assistants to perform various Gmail operations including:

• Fetching emails from your inbox
• Searching emails by subject
• Searching emails from specific senders
• Retrieving unread emails
• Sending emails to recipients

The server uses IMAP for email retrieval and SMTP for sending emails, all secured through Gmail's authentication system.
