The Notebook MCP

A Model Context Protocol (MCP) server that enables AI agents to interact with Jupyter Notebook (.ipynb) files. Designed to overcome limitations with Cursor's AI agent mode, this tool allows AI assistants to directly manipulate notebook cells and structure through a secure, well-defined API.

Current Version: 0.9.0 - See the CHANGELOG.md for details on recent changes.

Why Use This?

• For Cursor Users: Enables AI assistants to properly edit, create, and manipulate Jupyter notebooks.
• For Data Scientists: No more copy-pasting AI output manually into your notebooks.
• For Developers: Create complex notebook workflows with AI assistance while maintaining proper notebook structure.

Although originally designed for Cursor, this MCP server can be used with any MCP-compatible AI assistant tool, such as Claude Code.

Quick Start (no install)

# Run (minimal example)
uvx the-notebook-mcp --allow-root /path/to/your/notebooks

# Too see command options...
uvx the-notebook-mcp help

Video Walkthrough

Cursor Jupyter Notebook MCP Server Tutorial demonstrates:

• Installation and configuration
• Creating notebooks from scratch
• Using editing tools (edit, split, duplicate cells)
• Working with notebook metadata
• Exporting notebooks to Python

Features

The server provides the following MCP tools:

File Operations

• notebook_create: Creates a new, empty notebook file
• notebook_delete: Deletes an existing notebook file
• notebook_rename: Renames/moves a notebook file from one path to another
• notebook_export: Exports the notebook to another format (python, html, etc.)
• notebook_validate: Validates the notebook structure against the nbformat schema

Reading Operations

• notebook_read: Reads an entire notebook and returns its structure as a dictionary
• notebook_read_cell: Reads the source content of a specific cell
• notebook_get_cell_count: Returns the total number of cells
• notebook_get_info: Retrieves general information about the notebook
• notebook_get_outline: Generates a structural outline of the notebook (headings, definitions)
• notebook_search: Searches for a string within all notebook cells

Cell Manipulation

• notebook_add_cell: Adds a new code or markdown cell
• notebook_edit_cell: Replaces the source content of a specific cell
• notebook_delete_cell: Deletes a specific cell
• notebook_move_cell: Moves a cell to a different position
• notebook_change_cell_type: Changes a cell's type (code, markdown, or raw)
• notebook_duplicate_cell: Duplicates a cell multiple times
• notebook_split_cell: Splits a cell into two at a specified line number
• notebook_merge_cells: Merges a cell with the one immediately following it
• notebook_execute_cell: Executes a code cell and returns its outputs
  • Note: Requires an active Jupyter server
  • Example: notebook_execute_cell('/path/to/notebook.ipynb', 1, server_url='http://localhost:8888', token='your-token')
  • Kernel state is preserved between calls, allowing variables defined in earlier cells to be accessed in later cells

Metadata and Outputs

• notebook_read_metadata: Reads the top-level notebook metadata
• notebook_edit_metadata: Updates the top-level notebook metadata
• notebook_read_cell_metadata: Reads the metadata of a specific cell
• notebook_edit_cell_metadata: Updates the metadata of a specific cell
• notebook_read_cell_output: Reads the output list of a specific code cell
• notebook_clear_cell_outputs: Clears the outputs and execution count of a specific cell
• notebook_clear_all_outputs: Clears outputs and execution counts for all code cells

Requirements

Python Dependencies

• Python Version: ≥ 3.10

• Core Dependencies: (automatically installed)

  • fastmcp ≥ 2.3.3
  • nbformat ≥ 5.0
  • nbconvert ≥ 6.0
  • ipython
  • jupyter_core
  • loguru ≥ 0.7.3

• SSE Transport: (install with uv pip install "the-notebook-mcp[sse]")

  • uvicorn ≥ 0.20.0

External System Dependencies

For exporting to certain formats, you may need:

• Pandoc: Required for many non-HTML export formats (installation instructions)
• LaTeX: Required for PDF export (installation instructions)

Installation

No Install!

You can run the server directly with

uvx the-notebook-mcp --allow-root $PWD

But if you prefer to install it...

# Basic installation (stdio transport only)
uv tool install the-notebook-mcp

# Using pip
pip install the-notebook-mcp

Development Installation

1. Clone the repository:

   git clone https://github.com/svallory/the-notebook-mcp.git
   cd the-notebook-mcp
   

2. Create and activate a virtual environment:

   uv venv
   source .venv/bin/activate  # On Windows use `.venv\Scripts\activate`
   

3. Install in development mode:

   uv pip install -e ".[dev]"
   

4. Set up pre-commit hooks (recommended):

   pre-commit install
   

   See Pre-commit Hook Setup for details.

Running the Server

Basic Usage

# stdio transport (default)
the-notebook-mcp --allow-root /path/to/notebooks

# SSE transport
the-notebook-mcp --transport sse --allow-root /path/to/notebooks --host 0.0.0.0 --port 8889

Development Mode

Use one of these methods when working with the source code:

# Using poethepoet tasks
uv run poe start

# Using the Python module
python -m the_notebook_mcp.server --allow-root /path/to/notebooks

Available Tasks (poethepoet)

The project includes these predefined tasks:

• start: Start the server with default settings
• check-help: Show help information
• check-version: Show version information
• test: Run the test suite

Example:

# Show help
uv run poe check-help

# Run tests
uv run poe test

Command-Line Arguments

• --allow-root: (Required) Path to a directory where notebooks are allowed (can be used multiple times)
• --transport: stdio (default) or sse
• --host: Host for SSE transport (default: 0.0.0.0)
• --port: Port for SSE transport (default: 8889)
• --max-cell-source-size: Maximum bytes for cell source (default: 10MB)
• --max-cell-output-size: Maximum bytes for cell output (default: 10MB)
• --log-dir: Directory for log files (default: ~/.the_notebook_mcp)
• --log-level: DEBUG, INFO (default), WARNING, ERROR, CRITICAL

Cursor Integration

To configure Cursor to use this server, add settings to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project-specific).

No-Install stdio Transport

[!IMPORTANT] Cursor will expand the "." argument, but it does not expand "./some/folder".

{
  "mcpServers": {
    "the-notebook-mcp": {
      "command": "uvx",
      "args": [
        "the-notebook-mcp",
        "start",
        "--allow-root",
        "."
      ]
    }
  }
}

stdio Transport

{
  "mcpServers": {
    "the-notebook-mcp": {
      "command": "the-notebook-mcp",
      "args": [
        "start",
        "--allow-root",
        "."
      ]
    }
  }
}

SSE Transport (Recommended)

[!NOTE] You'll need to run the server separately

{
  "mcpServers": {
    "notebook_mcp": {
      "url": "http://127.0.0.1:8889/sse"
    }
  }
}

Limitations and Security

• Security Measures:
  • Paths are restricted to allowed root directories
  • Size limits on cell sources and outputs
  • Input validation for file extensions and types

Development & Testing

# Setup
uv venv
source .venv/bin/activate
uv pip install -e ".[dev]"
pre-commit install

# Testing
uv run poe test

Known Issues

• UI Refresh Issues: Some operations may succeed at the file level, but the Cursor UI might not update immediately. To fix, close and reopen the notebook or choose "Revert" when prompted.
