Notion MCP Server: Integrating AI Applications with Personal Todo Lists through Model Context Protocol (MCP)

Overview: What is Notion MCP Server?

The Notion MCP Server is a specialized implementation that bridges the gap between AI applications and personal task management systems, specifically integrating with Notion's API to manage a minimalist todo list. This server acts as an intermediary, adhering to the Model Context Protocol (MCP) which allows for seamless interaction between AI tools like Claude Desktop and targeted data sources or tools. By utilizing this MCP-compliant server, developers can enrich their applications with real-time updates from Notion databases, thereby enhancing the productivity and automation capabilities of their AI workflows.

🔧 Core Features & MCP Capabilities

The Notion MCP Server offers a robust set of features tailored to manage personal todo lists efficiently. Key functionalities include:

• Adding New Todo Items: Users can easily add tasks directly through CLI commands or predefined prompts.
• Viewing Todos: Comprehensive tools for retrieving all todo items, filtering them by completion status or time relevance (today/later).
• Task Completion: Mark tasks as completed with real-time updates to Notion's backend.
• Advanced Feature Integration: The latest release includes enhanced descriptions of tasks, providing richer context for each action item.

By complying with the MCP protocol, this server ensures compatibility and interoperability across various AI clients such as Claude Desktop, Continue, and Cursor. This integration is designed to streamline personal productivity, making it easier for users to manage their daily tasks directly from popular AI applications.

This sequence diagram details the comprehensive process from receiving an MCP request, parsing it to understand what action is needed (fetching data, updating a task), and then executing those actions via Notion's API.

🚀 Getting Started with Installation

Installing the Notion MCP Server involves the following steps:

1. Cloning Repository:

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

2. Setting Up Python Environment:

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

3. Creating Notion Integration:

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

4. Sharing Database with Integration:

   • Open your todo database in Notion, click on "..." menu → “Add Connections,” and select your integration.

5. Creating Environment File (.env):

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

6. Configuring Claude Desktop:

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

7. Running the Server:

   • Directly from command line:

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

   • Through Claude Desktop (recommended), ensuring it starts and stops automatically with Claude.

💡 Key Use Cases in AI Workflows

The Notion MCP Server is particularly useful for developers aiming to integrate personal task management directly within their AI workflows. By leveraging this server, users can:

1. Automate Task Management: Ensure that daily tasks are automatically synchronized between the Notion database and popular AI tools like Claude Desktop.
2. Enhance Productivity: Easily manage and track todos without leaving the interface of an AI application.

Use Case 1: Daily Routine Scheduling

Using an AI assistant, users can efficiently schedule their daily routines by simply stating commands:

"Add a task for today: check emails"

The server then updates Notion with this task details, ensuring that it remains up-to-date and easily accessible via the MCP protocol.

Use Case 2: Complex Todo Lists Management

For more complex todo lists, developers can use advanced features to manage multiple tasks across different days or categories:

"Add a task for tomorrow: prepare presentation"

The server processes this command, scheduling the task appropriately in Notion's respective database, ensuring seamless interaction between AI applications and Notion.

🔌 Integration with MCP Clients

This server supports integration with the following MCP clients:

MCP Client	Resources	Tools	Prompts	Status
