LightRAG

Indexes your documents into a knowledge graph and answers agent questions with local, global, hybrid, or mix retrieval modes.

What it provides

Knowledge graphRAG queriesDocument ingest

Connect an existing HTTPS deployment, with a scoped token where the service requires one. Heavy jobs stay on that service instead of using bot memory.

Connection requirements

A LightRAG API server (default port 9621) published through HTTPS. Start it with LIGHTRAG_API_KEY set, keep X-API-Key selected, and paste the same key below. Send either X-API-Key or an account bearer token, never both: LightRAG validates the bearer token first and rejects the request if that one is invalid. Indexing, embeddings, and the graph store stay on the LightRAG host.

Where to add it

Open Dashboard Tools, select a running OpenClaw or Hermes instance, then use the card’s Install or Connect action. External services may require an HTTPS endpoint and credentials; the dashboard shows those fields before anything is saved.
