</h2>

```python theme={null}
Neo4jGraphCapability(query_engine: Neo4jGraphQueryEngine)
```

The Neo4j graph capability integrates Neo4j Property graph into a graph rag agent.<br />Ref: [https://neo4j.com/labs/genai-ecosystem/llamaindex/#\_property\_graph\_constructing\_modules](https://neo4j.com/labs/genai-ecosystem/llamaindex/#_property_graph_constructing_modules)

For usage, please refer to example notebook/agentchat\_graph\_rag\_neo4j.ipynb
