# PageIndex MCP (MCP server)

> PageIndex MCP is an MCP server that adds search and knowledge tools to AI assistants such as Claude Desktop, Claude Code and Cursor. Reasoning-based RAG system for chatting with long PDFs. It has 399 GitHub stars, is released under the MIT license and runs locally with npx -y @pageindex/mcp.

If you find this repo useful, please also star our main PageIndex repo ⭐ 📘 PageIndex is a vectorless, reasoning-based RAG system that represents documents as hierarchical tree structures. It enables LLMs to navigate and retrieve information through structure and reasoning, not vector similarity — much like a human would retrieve information using a book's index.
