This extension is composed of a Python package named `jupyter_mcp_tools`
for the server extension and a NPM package named `@datalayer/jupyter-mcp-tools`
for the frontend extension.

It enables the use of JupyterLab commands as MCP tools.

This extension is used by [jupyter-mcp-server](https://github.com/datalayer/jupyter-mcp-server) to enable JupyterLab commands such as opening notebooks through MCP tools.

## Execution Modes

The extension supports two execution modes for JupyterLab commands:

### Local Mode

- **Direct Execution**: Commands are executed directly within the JupyterLab frontend using the built-in command registry
- **No Network Required**: Immediate execution without WebSocket communication
- **Use Case**: Testing commands and direct UI interaction within JupyterLab itself
- **Implementation**: Calls `app.commands.execute()` directly in the browser

### Remote Mode

- **WebSocket Communication**: Commands are sent via WebSocket to the backend server extension
- **External Access**: Enables external MCP clients to execute JupyterLab commands remotely
- **Use Case**: Integration with AI agents and MCP clients like [jupyter-mcp-server](https://github.com/datalayer/jupyter-mcp-server)
- **Implementation…
