n8n GraphRAG Nodes

The FalkorDB GraphRAG n8n community node connects n8n workflows to a FalkorDB GraphRAG-Server. It does not talk to FalkorDB directly. Instead, it uses the GraphRAG-Server REST API to ingest content into a knowledge graph and answer questions against that graph.

The package ships two nodes and one shared credential:

• FalkorDB GraphRAG: a regular pipeline node for ingest and question-answering steps.
• FalkorDB GraphRAG Tool: an AI Agent tool node that can be called autonomously.
• FalkorDB GraphRAG Server API: the credential that stores the server URL, API token, and request timeout.

Installation

Install @falkordb/n8n-nodes-graphrag from the n8n Community Nodes UI, or use npm in a self-hosted n8n instance:

npm install @falkordb/n8n-nodes-graphrag

After installation, the two nodes appear under the FalkorDB category in the node picker.

Setup

Create one credential under Credentials -> New -> FalkorDB GraphRAG Server API and reuse it across both nodes.

Field	Required	Description
Server URL	yes	Base URL of your GraphRAG-Server instance, for example http://localhost:8000.
API Token	no	Sent as Authorization: Bearer ... when the server requires authentication.
Request Timeout (Seconds)	yes	Per-request timeout for GraphRAG-Server calls.

When to use it

Use the pipeline node when you want to ingest documents, list documents, or answer questions as part of a workflow. Use the AI Agent tool when you want the agent to decide when to query the knowledge graph and fill the node parameters automatically.
