Draw Neo4j graph data models with an AI assistant

Connect the AI assistant you already use, and it can turn a description, a document, a spreadsheet, or a database schema into a graph data model. The model lands in your toro4n account, laid out and ready to edit. Ask for changes while you have it open, and you'll see them as they happen. toro4n works with any assistant that can connect to a remote Model Context Protocol (MCP) server.

Server address

https://toro4n.com/mcp

Assistants work only with models you've saved online, so you'll need to sign in to toro4n, with Google or with a code we email you.

Connecting

Claude (claude.ai and the desktop and mobile apps): go to Customize › Connectors › Add custom connector. Paste the address, add the connector, and choose Connect. Then, in any chat, use the + button to turn it on.
ChatGPT: in Settings, under Apps, turn on developer mode. Then create an app, paste the address, and choose OAuth for authentication. Developer mode isn't available on every ChatGPT plan.
Claude Code: claude mcp add --transport http toro4n https://toro4n.com/mcp
Antigravity CLI, which replaced Gemini CLI: add toro4n to ~/.gemini/config/mcp_config.json: {"mcpServers": {"toro4n": {"serverUrl": "https://toro4n.com/mcp"}}}
VS Code with Copilot, Cursor, and other MCP clients: add the address as a remote HTTP MCP server.

The first time you connect, your assistant sends you to toro4n to sign in and click Allow. It can't reach your models until you do.

What to ask

"Sketch a graph model of our order system from this document." "Draw the schema in this spreadsheet as a Neo4j model." "Add invoices to my bookstore model." The assistant replies with a link that opens the model in toro4n.

The six tools

list_models – every model you've saved online or that's been shared with you, with your role on it and the folder you've filed it in.
get_model – a model's nodes, relationships, notes, and layers.
create_model – a new model from nodes, relationships, and notes, laid out automatically.
edit_model – a list of changes, applied together or not at all: add, change, and remove nodes, relationships, properties, and notes, and remove and rename layers.
list_versions and restore_version – list a model's earlier versions and restore one.

The assistant follows the same rules you do: no two nodes with the same labels, Neo4j's naming conventions, and property types from the Type list. If a change breaks a rule, toro4n tells the assistant what to fix. The assistant can do only what your role on a model allows.

Staying in control

Before an assistant changes a model, we save a version, so you can go back if you don't like the result. In Version history, the assistant's changes appear under your email address and the assistant's name, for example "you@example.com via Claude". To see which assistants are connected, or to disconnect one, go to Account › AI assistants.

Anything your assistant reads from your models goes to the company that runs it, under that company's terms. toro4n never contacts an AI provider itself.

Questions

Which AI assistants work with toro4n?

Any assistant that can connect to a remote MCP server: Claude (claude.ai and its apps), ChatGPT in developer mode, Claude Code, Antigravity, VS Code with Copilot, Cursor, and others. Connect it to https://toro4n.com/mcp.

Can the assistant delete my models?

No. It can list, read, create, and edit models, and restore earlier versions, but only where your role allows. It can't delete or share a model. If you don't like a change it made, open Version history and restore the version from just before it.
