What is GraphRAG MCP Server?
GraphRAG MCP is a server that integrates Neo4j (graph database) and Qdrant (vector database) to provide a hybrid retrieval system for large language models (LLMs). It follows the Model Context Protocol (MCP) specification, allowing seamless integration with MCP-enabled clients.
How to use GraphRAG MCP Server?
To use GraphRAG MCP, clone the repository, install dependencies using uv, configure database connections in the .env file, and run the server. Then, add the server to your MCP configuration file (e.g., ~/.cursor/mcp.json) and restart your MCP client. You can then use the provided tools like search_documentation and hybrid_search within your LLM context.
