Neo4j

What is the Neo4j tool?

The Neo4j tool is a built-in capability in the Agno framework that allows AI agents to interact with neo4j graph databases. When added to an agent in Agno Builder, the agent can autonomously decide when to invoke this tool based on the user's request.

This tool requires a NEO4J_URI environment variable. Get your API key at neo4j.com.

How to use Neo4j in Agno Builder

1. 1

   Create an agent

   Drag an Agent node onto the canvas in Agno Builder, or use one of the built-in templates.

2. 2

   Enable Neo4j

   Click the agent, go to the Tools tab, and toggle on "Neo4j" from the data category.

3. 3

   Add your API key

   Enter your NEO4J_URI in the tool configuration. Your key stays in your browser and is never stored on our servers.

4. 4

   Test in chat

   Open the chat panel and send a message. The agent will automatically use Neo4j when relevant.

5. 5

   Export Python code

   Click File > Export Python to get clean, runnable code with the correct imports for Neo4j.

Python code example

This is the code Agno Builder exports when you use Neo4j:

from agno.agent import Agent
from agno.models.openai import OpenAIChat
from agno.tools.neo4j import Neo4jTools

agent = Agent(
    name="Neo4j Agent",
    model=OpenAIChat(id="gpt-4o"),
    tools=[Neo4jTools()],
    instructions=["Use the neo4j tool to help the user."],
    markdown=True,
)

agent.print_response("Help me with a neo4j task")

Install with: pip install agno # + set NEO4J_URI
