Neo4j

Neo4jTools enables agents to interact with Neo4j graph databases for querying and managing graph data.

Prerequisites

The following example requires the neo4j library.

uv pip install -U neo4j

You will also need a Neo4j database. The following example uses a Neo4j database running in a Docker container.

docker run -d -p 7474:7474 -p 7687:7687 --name neo4j -e NEO4J_AUTH=neo4j/password neo4j

Make sure to set the NEO4J_URI environment variable to the URI of the Neo4j database.

    export NEO4J_URI=bolt://localhost:7687
    export NEO4J_USERNAME=neo4j
    export NEO4J_PASSWORD=password
    export OPENAI_API_KEY=xxx

Install dependencies

uv pip install -U neo4j openai agno

Example

The following agent can interact with Neo4j graph databases:

neo4j_tools.py

from agno.agent import Agent
from agno.tools.neo4j import Neo4jTools

agent = Agent(
    instructions=[
        "You are a graph database assistant that helps with Neo4j operations",
        "Execute Cypher queries to analyze graph data and relationships",
        "Provide insights about graph structure and patterns",
        "Help with graph data modeling and optimization",
    ],
    tools=[Neo4jTools()],
)

agent.print_response("Show me the schema of the graph database", stream=True)

Save the code above as neo4j_tools.py, then run:

python neo4j_tools.py
