Example Use Cases

1
Perform semantic or keyword search over uploaded documents using LightRAG's retrieval features.
2
Ingest, index, and track document processing (uploading files, inserting text, batch imports, and pipeline status).
3
Manage a knowledge graph (create/edit/delete entities and relations) and check LightRAG API health.

Description

LightRAG MCP Server acts as a bridge between the LightRAG API and MCP clients, enabling semantic and keyword document queries, document ingestion and indexing, and knowledge graph operations. It provides tools for uploading, scanning, and tracking documents, creating and editing entities and relations, and monitoring LightRAG API health. The server is intended to be run as an MCP server (configured via mcp-config.json) and requires a running LightRAG API instance.
