What is Notion Mcp

notion_mcp is a simple Model Context Protocol (MCP) server that integrates with Notion’s API, allowing users to manage a personal todo list through Claude.

Use cases

Use cases include managing daily tasks, tracking project milestones, and organizing personal to-do lists in a minimalist way.

How to use

To use notion_mcp, clone the repository, set up a Python environment, create a Notion integration, share your database with the integration, and configure Claude Desktop with your API key and database ID.

Key features

Key features include adding new todo items, viewing all todos, viewing today’s tasks, and checking off tasks as complete.

Where to use

notion_mcp can be used in personal productivity applications, task management systems, and any scenario where users want to manage tasks in Notion.

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.

Important Note

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

• Task (title)
• When (select with only two options: “today” or “later”)
• Checkbox (marks if completed)

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
• View all todos
• View today’s tasks
• Check off a task as complete

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:

   • Go to https://www.notion.so/my-integrations
   • Create new integration
   • Copy the API key

4. Share your database with the integration:

   • Open your todo database in Notion
   • Click “…” menu → “Add connections”
   • Select your 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”
• “What’s on my list for today?”
• “Add a todo for today: check emails”
• “Add a task for later: review project”

Limitations

• Only works with a specific Notion database structure
• No support for complex database schemas
• Limited to “today” or “later” task scheduling
• No support for additional properties or custom fields
• Basic error handling
• No advanced features like recurring tasks, priorities, or tags

Customization

If you want to use this with a different database structure, you’ll need to modify the server.py file, particularly:

• The create_todo() function to match your database properties
• The todo formatting in call_tool() to handle your data structure
• The input schema in list_tools() if you want different options
