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.

​
Typical workflow

​
Installation

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

​
How to get an API token

Use these steps in GraphRAG-Server before configuring the n8n credential.

​
1. Open Settings and API Access

Open your graph in GraphRAG-Server, then go to Settings and keep the API Access tab selected. GraphRAG-Server Settings page with API Access selected

​
2. Add your LLM key

In Your LLM Keys, add a provider key if one is not already present. API tokens run on your own LLM key, so this step is required first. LLM key section in GraphRAG-Server Settings

​
3. Generate the client API token

In API Tokens, enter a token name (for example, n8n production), choose expiration, and click Generate. Copy the raw token value when shown and paste it into the n8n credential API Token field. API Tokens panel showing token generation controls

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.
