Google Drive MCP Server

A Model Context Protocol (MCP) server that provides AI agents with efficient access to Google Drive documents. The server downloads files locally, converts them to markdown, and offers selective content extraction to optimize context window usage.

Features

• Document Processing: Convert Google Docs, PDFs, and Word documents to markdown

• Selective Content Extraction: Extract specific sections, page ranges, or keyword-based content

• Intelligent Caching: Local caching with LRU eviction and TTL-based expiration

• Advanced Search: Search files by name, type, content, and metadata

• Permission Management: Respect Google Drive permissions and sharing settings

• MCP Protocol Compliance: Full integration with MCP-compatible AI agents
