Notion MCP Server: Integrating AI Applications with Notion

Overview: What is Notion MCP Server?

Notion MCP Server is a specialized implementation of the Model Context Protocol (MCP) infrastructure designed to integrate AI applications, specifically with Notion, a versatile knowledge management platform. This server acts as a bridge, enabling seamless communication between AI tools like Claude Desktop and the comprehensive databases within Notion. By adhering to MCP standards, this server ensures that various AI applications can efficiently interact with Notion's API, providing a unified interface for complex data operations.

🔧 Core Features & MCP Capabilities

Notion MCP Server includes several core features and MCP capabilities:

1. List and Query Databases: Users can list all available databases within the Notion workspace and query specific records based on custom filters.
2. Create and Update Pages: The server supports creating new pages or updating existing ones in Notion, ensuring data is always up-to-date.
3. Search Across Workspace: A powerful search functionality allows users to find critical information faster by filtering through all content within the workspace.
4. Get Database Details and Block Children: Detailed database metadata and block children support streamline data management and retrieval processes.

In terms of MCP capabilities, Notion MCP Server incorporates:

• Full Async/Await Support with httpx: Ensures smooth, non-blocking interactions that optimize performance.
• Type-Safe with Pydantic v2 Models: Provides robust type validation for data structures, ensuring minimal errors in the interaction process.
• Proper Error Handling with Detailed Logging: Enables comprehensive logging to aid debugging and maintain system reliability.

⚙️ MCP Architecture & Protocol Implementation

Notion MCP Server is built around a modular architecture that adheres strictly to the Model Context Protocol (MCP). This protocol defines how AI applications can interact with data sources, ensuring compatibility across various tools. At its core:

1. Client Initialization: The client initiates a connection by communicating with Notion's API using MCP-defined messages.
2. Async/Await Handling: Uses httpx for asynchronous requests, maintaining performance and reliability.
3. Error Resolution: Detailed error logging and handling mechanisms ensure that issues are accurately identified and resolved.

🚀 Getting Started with Installation

To install and run Notion MCP Server, follow these steps:

1. Clone the Repository:

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

2. Create a Virtual Environment and Install Dependencies (using uv):

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

Alternatively, using standard venv:

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

3. Create a .env File: Add your Notion API key to this file in the root directory.

🛠️ Advanced Configuration & Security

MCP Configuration Sample

Below is an example of how to configure the Notion MCP Server in your claude_desktop_config.json:

{
    "mcpServers": {
        "notion-mcp": {
            "command": "/Users/username/Projects/notion-mcp/.venv/bin/python",
            "args": ["-m", "notion_mcp"],
            "cwd": "/Users/username/Projects/notion-mcp"
        }
    }
}

Security Considerations

Ensure that your Notion API key is securely stored and not exposed in any public repositories. Regularly update the server to maintain compatibility with new MCP versions.
