A JupyterLab extension for Chat with AI supporting Model Context Protocol (MCP). This extension integrates AI and provides interactive tool usage capabilities through MCP servers.

• Seamless integration with AI models (Currently supported models are Anthropi. More models are coming soon. )
• Real-time streaming of responses with step-by-step reasoning
• Support for MCP server tools with interactive execution:
• Rich content display
• Interactive chat interface

• JupyterLab >= 4.0.0
• An Anthropic API key for Claude access
• Running MCP server(s) for tool integration (optional)

The extension supports multiple Claude models through the Anthropic API. You'll need to:

1. Obtain an Anthropic API key from Anthropic's website
2. Configure your models in JupyterLab's Settings Editor under the "MCP Chat" section
3. For each model, provide:
   • Name (e.g., "gpt-4")
   • API Key
   • Set as default (optional)

To install the extension, execute:

pip install mcp_client_jupyter_chat

To remove the extension, execute:

pip uninstall mcp_client_jupyter_chat

Note: You will need NodeJS to build the extension package.

The jlpm command is JupyterLab's pinned version of yarn that is installed with JupyterLab. You may use yarn or npm in lieu of jlpm below.

# Clone the repo to your local environment
# Change directory to the mcp_client_jupyter_chat directory
# Install package in development mode
pip install -e "."
# Link your development version of the extension with JupyterLab
jupyter labextension develop . --overwrite
# Rebuild extension Typescript source after making changes
jlpm build

You can watch the source directory and run JupyterLab at the same time in different terminals to watch for changes in the extension's source and automatically rebuild the extension.

# Watch the source directory in one terminal, automatically rebuilding when needed
jlpm watch
# Run JupyterLab in another terminal
jupyter lab

With the watch command running, every saved change will immediately be built locally and available in your running JupyterLab. Refresh JupyterLab to load the change in your browser (you may need to wait several seconds for the extension to be rebuilt).

By default, the jlpm build command generates the source maps for this extension to make it easier to debug using the browser dev tools. To also generate source maps for the JupyterLab core extensions, you can run the following command:

jupyter lab build --minimize=False

pip uninstall mcp_client_jupyter_chat

In development mode, you will also need to remove the symlink created by jupyter labextension develop command. To find its location, you can run jupyter labextension list to figure out where the labextensions folder is located. Then you can remove the symlink named mcp-client-jupyter-chat within that folder.

This extension is using Jest for JavaScript code testing.

To execute them, execute:

jlpm
jlpm test

This extension uses Playwright for the integration tests (aka user level tests). More precisely, the JupyterLab helper Galata is used to handle testing the extension in JupyterLab.

More information are provided within the ui-tests README.
