Lightrag MCP Server
LightRAG API integration for document retrieval, graph management, and status monitoring.
Data last scanned last week · Reviewed last month
Overview
LightRAG MCP Server functions as a bridge, enabling direct communication between the LightRAG API and MCP-compatible AI clients. It exposes core RAG functionalities, including semantic and keyword-based document searching, document indexing, and knowledge graph entity relationship management. The server supports both stdio and streamable-http transport modes, allowing for flexible deployment options within your existing local infrastructure. Users can configure host, port, and authentication credentials through command-line arguments to sync the server with an active LightRAG API instance.
Our verdict
This project holds a high risk level with a security score of 32/100, largely because it lacks an open-source license and is community-maintained rather than vendor-backed. Given these legal and maintenance uncertainties, it is recommended only for development or testing environments, rather than mission-critical workflows, until the licensing is clarified and further editorial or security reviews are performed.
- Supports both stdio and streamable-http transport protocols
- Provides direct control over knowledge graph and indexing operations
- Features a minimal implementation with zero direct dependencies
- No license detected, creating legal ambiguity for users
- Community-maintained without official vendor oversight
- Authentication methods have not yet undergone security review
