This release is a pre-release and may not be stable for production use.
nteract
A convenience wrapper that finds and launches runt mcp — the MCP server shipped with the nteract desktop app.
Download the nteract desktop app — you'll need it to see notebooks, collaborate with agents, and manage environments.
The recommended way to add the MCP server is
runt mcpdirectly. This PyPI package is a convenience for users who preferuvx.
Quick Start
The MCP server ships with the desktop app. After installing, use runt mcp directly:
Claude Code
# Stable
claude mcp add nteract -- runt mcp
# Nightly
claude mcp add nteract-nightly -- runt-nightly mcp
Manual JSON config
{
"mcpServers": {
"nteract": {
"command": "runt",
"args": ["mcp"]
}
}
}
Via this PyPI package
If runt isn't on your PATH, this package finds it in the app bundle:
claude mcp add nteract -- uvx nteract
That's it. Now Claude can execute Python code, create visualizations, and work with your data.
What is this?
nteract is an MCP (Model Context Protocol) server that connects AI assistants like Claude to Jupyter notebooks. It enables:
- Code execution: Run Python in a persistent kernel
- Real-time collaboration: Watch the AI work in the nteract desktop app
- Shared state: Multiple agents can work on the same notebook
- Environment management: Automatic Python environment setup
Example
Ask Claude:
"Help me visualize my log data"
Claude will:
- Connect to a notebook session
- Write and execute code
- Generate visualizations
- Show you the results
You can open the same notebook in the nteract desktop app to see changes in real-time and collaborate with the AI.

CLI Flags
| Flag | Description |
|---|---|
--version |
Print version and exit |
--nightly |
Use runt-nightly (nightly daemon and app) |
--stable |
Use runt (stable daemon and app, default) |
--legacy |
Use the built-in Python MCP server instead of runt mcp |
By default, nteract finds and exec's the installed runt (or runt-nightly) binary. The --legacy flag falls back to the built-in Python MCP server.

- nteract (this package): MCP server for AI assistants
- runtimed: Low-level daemon and Python bindings (docs)
- nteract desktop: Native app for humans to collaborate with AI
Real-time Collaboration
The magic of nteract is that AI and humans share the same notebook:
- AI connects via MCP and runs code
- Human opens the same notebook in nteract desktop
- Changes sync instantly via CRDT
- Both see the same kernel state
This enables workflows like:
- AI does initial analysis, human refines
- Human writes code, AI debugs errors
- Multiple AI agents collaborate on complex tasks
Development
# Clone
