Notion MCP Integration

A simple Model Context Protocol (MCP) server that integrates with Notion's API to manage my personal todo list through Claude. This is a basic implementation tailored specifically for my minimalist todo list setup in Notion.

> This project is based on danhilse/notion_mcp, which is available under the MIT license.

Important Note

This is a personal project designed for a very specific use case: my simple Notion todo list that has just four properties:

• Task (title)
• Checkbox (marks if completed)
• Description (additional details)
• Link (URL or reference)

Example Notion Database

While you can use this as a starting point for your own Notion integration, you'll likely need to modify the code to match your specific database structure and requirements.

Features

• Add new todo items with descriptions and links
• View all todos
• Check off tasks as complete
• Link external resources to tasks

Prerequisites

• Python 3.10 or higher
• A Notion account
• A Notion integration (API key)
• A Notion database that matches the exact structure described above (or willingness to modify the code for your structure)

Setup

1. Clone the repository:

git clone https://github.com/yourusername/notion-mcp.git
cd notion-mcp

2. Set up Python environment:

python -m venv .venv
source .venv/bin/activate  # On Windows use: .venv\Scripts\activate
uv pip install -e .

3. Create a Notion integration:

4. Share your database with the integration:

5. Create a `.env` file:

NOTION_API_KEY=your-api-key-here
NOTION_DATABASE_ID=your-database-id-here

6. Configure Claude Desktop:

{
  "mcpServers": {
    "notion-todo": {
      "command": "/path/to/your/.venv/bin/python",
      "args": ["-m", "notion_mcp"],
      "cwd": "/path/to/notion-mcp"
    }
  }
}

Running the Server

The server can be run in two ways:

1. Directly from the command line:

# From the project directory with virtual environment activated
python -m notion_mcp

2. Automatically through Claude Desktop (recommended):

• The server will start when Claude launches if configured correctly in `claude_desktop_config.json`
• No manual server management needed
• Server stops when Claude is closed

Note: When running directly, the server won't show any output unless there's an error - this is normal as it's waiting for MCP commands.

Usage

Basic commands through Claude:

• "Show all my todos"
• "Add a todo: check emails"
• "Add a todo: review project docs, with link: https://example.com/docs"
• "Mark todo [ID] as complete"

Limitations

• Only works with a specific Notion database structure
• No support for complex database schemas
• Basic error handling
• No support for additional properties or custom fields
• No advanced features like recurring tasks, priorities, or tags
