Google Workspace MCP Server

A Model Context Protocol (MCP) server that provides tools for interacting with Gmail and Calendar APIs. This server enables you to manage your emails and calendar events programmatically through the MCP interface.

Features

Gmail Tools

• `list_emails`: List recent emails from your inbox with optional filtering
• `search_emails`: Advanced email search with Gmail query syntax
• `send_email`: Send new emails with support for CC and BCC
• `modify_email`: Modify email labels (archive, trash, mark read/unread)

Calendar Tools

• `list_events`: List upcoming calendar events with date range filtering
• `create_event`: Create new calendar events with attendees
• The events below were removed from this server for security measures since Google Cloud Calendar API does not have a scope that allows creation but prevents deletion or updates.

• `delete_event`: Delete calendar events
