Neo4j integration for AI agents

Sim's Neo4j integration adds 7 tools to the AI agents you build in Sim's visual workflow builder. Connect to Neo4j graph database.

You can query (MATCH), create Nodes/Relationships, merge (Find or Create), update properties (SET), and delete Nodes/Relationships with Neo4j in Sim, plus 2 more Neo4j tools listed on this page. Each runs as a tool inside an AI agent, so the agent can combine Neo4j with any other connected service and apply LLM reasoning between steps.

(1) Create a free account at sim.ai. (2) Create an agent in your workspace. (3) Drag a Neo4j block onto the workflow builder. (4) No authentication is needed, so the block works as soon as you drop it in. (5) Pick a tool such as "Query (MATCH)", wire up its inputs, and click Run.

Add a Neo4j block to your agent and select "Query (MATCH)" as the tool. Execute MATCH queries to read nodes and relationships from Neo4j graph database. For best performance and to prevent large result sets, include LIMIT in your query (e.g., "MATCH (n:User) RETURN n LIMIT 100") or use LIMIT $limit with a limit parameter. Fill in the required fields. Inputs can reference outputs from earlier steps, such as text generated by an AI block or data fetched from another integration.
