Notion MCP Server: Integrating AI Applications with Notion Workspaces

Overview: What is Notion MCP Server?

The Notion MCP Server serves as an adapter between AI applications and the Notion platform, enabling seamless integration of these tools within various workflows. By leveraging Model Context Protocol (MCP), this server facilitates a standardized way for AI-powered applications such as Claude Desktop, Continue, Cursor, and others to interact with Notion's rich content management capabilities.

🔧 Core Features & MCP Capabilities

The Notion MCP Server supports a suite of operations, including appending child blocks, retrieving block information, deleting blocks, updating pages, and managing databases. These features empower AI applications to perform a wide range of tasks such as adding, fetching, modifying, and querying content within Notion workspaces.

The following sections outline the core capabilities of this MCP server, detailing how each operation can be used in different AI workflows.

⚙️ MCP Architecture & Protocol Implementation

At the heart of the Notion MCP Server is Model Context Protocol (MCP), which defines a structured method for communicating between AI applications and data sources. The protocol flow involves:

1. AI Application (Claude Desktop, Continue, Cursor): This client communicates through an MCP framework.
2. Notion MCP Server: Acts as the intermediary that translates requests from the AI application to Notion’s API endpoints.
3. Notion Data Source/Tool: Processed and modified according to the requirements of the AI application.

The architecture ensures seamless interaction between the AI application and Notion, leveraging MCP to handle complex operations efficiently and effectively.

🚀 Getting Started with Installation

To get started with the Notion MCP Server, follow these steps:

1. Create a Notion Integration:

   • Visit Notion Integrations Page.
   • Click "New Integration" to create an internal integration token.
   • Assign necessary permissions (e.g., Read content and Update content).

2. Retrieve the Secret Key:

   • Copy the "Internal Integration Token" obtained from the integration setup.

3. Add the Integration to Your Workspace:

   • Open a page or database that needs to be integrated.
   • Navigate to the right corner to access the “Connect to” button and add your Notion integration.

4. Configure Claude Desktop:

   • Add the following configuration to your claude_desktop_config.json file:

     {
       "mcpServers": {
         "notion": {
           "command": "node",
           "args": ["your-built-file-path"],
           "env": {
             "NOTION_API_TOKEN": "your-integration-token"
           }
         }
       }
     }
     

💡 Key Use Cases in AI Workflows

Real-Time Collaboration and Content Management

AI applications can dynamically update Notion pages in real-time. For instance, an assistant could automatically track project progress by updating relevant sections of a Notion database.

Technical Implementation:

notion_update_database({
  database_id: "1234",
  properties: {
    Task: "Complete initial setup",
    Status: "In Progress"
  }
});

Custom Automation and Data Entry

Using triggers from AI applications, certain blocks can be automatically filled with relevant data, streamlining the content creation process.

Technical Implementation:

notion_create_database_item({
  database_id: "1234",
  properties: {
    Title: { rich_text: [{ text: { content: "New Project" } }] },
    Description: { rich_text: [{ text: { content: "Detailed project description." } }] }
  }
});

🔌 Integration with MCP Clients

The Notion MCP Server is fully compatible with popular MCP clients:

• Claude Desktop: Full support for all operations.
• Continue: Full support for most operations.
