nteract 2.0.3a202603201118

Bring AI to Jupyter notebooks. MCP server for Claude, ChatGPT, Gemini, OpenCode and any agent.

nteract/nteract

What's going on?

If you're here looking for the Electron-based nteract desktop app, you can view the source in this repo. That desktop app is not actively maintained.

We're actively developing the spiritual successor to the nteract desktop app in the nteract/desktop repo.

The New Desktop App

We're actively developing the spiritual successor to the nteract desktop app in the nteract/desktop repo.

The new app is a native desktop app with instant startup and intelligent environment management.

Bringing Agents in the Loop

We're in the preliminary stages of hooking up the realtime system from nteract/desktop to any agent of your choice. Collaborate with agents in notebooks, render interactive elements, and explore data together.

Quick Start

Claude Code

# Stable desktop 1.4.x / stable MCP
claude mcp add nteract -- uvx nteract

For desktop nightly / the upcoming 2.x transition, use the prerelease MCP package and nightly socket:

claude mcp add nteract-nightly -- env RUNTIMED_SOCKET_PATH="$HOME/Library/Caches/runt-nightly/runtimed.sock" uvx --prerelease allow 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:

1. Connect to a notebook session
2. Write and execute code
3. Generate visualizations
4. 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.

Installation

Stable line for desktop 1.4.x:

uvx nteract

Prerelease line for desktop nightly / 2.x transition:

uvx --prerelease allow nteract

Claude Code Setup

Add stable nteract as an MCP server:

claude mcp add nteract -- uvx nteract

Or manually add to your Claude configuration:

{
  "mcpServers": {
    "nteract": {
      "command": "uvx",
      "args": ["nteract"]
    }
  }
}

Using with Nightly

If you're using nteract desktop nightly builds, point at the nightly socket and allow prereleases:

claude mcp add nteract -- env RUNTIMED_SOCKET_PATH="$HOME/Library/Caches/runt-nightly/runtimed.sock" uvx --prerelease allow nteract

Release Tracks

• main publishes prerelease nteract builds for the 2.x transition and tracks runtimed 2.x prereleases.
• release/1.9.x is the stable maintenance line for desktop 1.4.x and stays on runtimed 1.9.0.

• 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:

1. AI connects via MCP and runs code
2. Human opens the same notebook in nteract desktop
3. Changes sync instantly via CRDT
4. 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
