Memgraph AI Toolkit

A unified mono-repo for integrating AI-powered graph tools on top of Memgraph.
This repository contains the following libraries:

1. memgraph-toolbox Core Python utilities and CLI tools for querying and analyzing a Memgraph database. The package is available on the PyPi

2. langchain-memgraph A LangChain integration package, exposing Memgraph operations as LangChain tools and toolkits. The package is available on the PyPi

3. mcp-memgraph An MCP (Model Context Protocol) server implementation, exposing Memgraph tools over a lightweight STDIO protocol. The package is available on the PyPi

4. agents An intelligent database migration agent that automates the process of migrating from MySQL or Postgresql to Memgraph. Features automated schema analysis, intelligent graph modeling with interactive refinement, and data migration with validation.

Usage examples

For individual examples on how to use the toolbox, LangChain, MCP, or agents, refer to our documentation:

• Langchain examples
• MCP examples
• SQL2Graph migration examples - Interactive MySQL to Memgraph migration workflow

Developing locally

You can build and test each package directly from your repo. First, start a Memgraph MAGE instance with schema info enabled:

docker run -p 7687:7687 \\
  --name memgraph \\
  memgraph/memgraph-mage:latest \\
  --schema-info-enabled=true

Once Memgraph is running, install any package in “editable” mode and run its test suite. For example, to test the core toolbox:

uv pip install -e memgraph-toolbox[test]
pytest -s memgraph-toolbox/src/memgraph_toolbox/tests

Core tests

To test the core toolbox, just run:

uv pip install -e memgraph-toolbox[test]
pytest -s memgraph-toolbox/src/memgraph_toolbox/tests

Langchain integration tests

To run the LangChain tests, create a .env file with your OPENAI_API_KEY, as the tests depend on LLM calls:

uv pip install -e integrations/langchain-memgraph[test]
pytest -s integrations/langchain-memgraph/tests

MCP integration tests

uv pip install -e integrations/mcp-memgraph[test]
pytest -s integrations/mcp-memgraph/tests

Agent integration tests

uv pip install -e integrations/agents[test]
pytest -s integrations/agents/tests

To run a complete migration workflow with the agent:

cd integrations/agents
uv run main.py

Note: The agent requires both MySQL and Memgraph connections. Set up your environment variables in .env based on .env.example.

If you are running any test on MacOS in zsh, add "" to the command:

uv pip install -e memgraph-toolbox"[test]"
