All-in-One Google MCP is a unified, high-performance Model Context Protocol (MCP) backend powered by Google Apps Script (GAS). This innovative tool allows large language models (LLMs) such as Antigravity, Gemini, ChatGPT, and Claude to interact directly with Google Workspace services without any local overhead.

Key features include:

• Gmail: List threads, search emails, get details, send replies, archive, and delete.

• Drive: List files, search, create/update/delete files and folders, and share.

• Calendar: Manage events, search by date range, create/update/delete.

• Tasks: Unified task management (List, Create, Update, Delete).

• Sheets: Read, write, append, and clear spreadsheet data.

• Docs: Create, read, and append to Google Documents.

With seamless integration via mcp-remote, users can easily connect their LLM clients to this backend, making it compatible with various platforms including VS Code and other MCP-compatible clients. The tool is designed to enhance productivity by automating workflows across Google Workspace, offering a robust solution for developers and enterprises alike.
