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

Clone the repository:

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

Set up Python environment:

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

Create a Notion integration:
- Go to https://www.notion.so/my-integrations
- Create new integration
- Copy the API key
Share your database with the integration:
- Open your todo database in Notion
- Click "..." menu → "Add connections"
- Select your integration
Create a .env file:

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

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:

Directly from the command line:

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

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
