Notion MCP Server

A Model Context Protocol (MCP) server that exposes the official Notion SDK, allowing AI models to interact with Notion workspaces.

Quick Start

1. Set up your Notion integration

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

2. Connect your Notion pages to the integration

For your integration to access Notion content, you need to explicitly share your pages or databases with it:

Navigate to the Notion page or database you want to access through the integration
Click the "Share" button in the top-right corner
In the "Add people, groups, or integrations" field, select your integration from the dropdown list
Click "Invite"
Repeat for each page or database you want to make accessible

Note: An integration only has access to pages and databases that have been explicitly shared with it. Child pages automatically inherit access from parent pages.

3. Add to your AI assistant

You can add this MCP server to Claude Desktop, Cursor AI, or Claude.ai using either of these configuration formats:

Command Line Format

npx @ramidecodes/mcp-server-notion@latest -y --api-key=your-notion-integration-key

JSON Configuration Format

{
  "mcpServers": {
    "Notion": {
      "command": "npx",
      "args": [
        "@ramidecodes/mcp-server-notion@latest",
        "-y",
        "--api-key=your-notion-integration-key"
      ]
    }
  }
}

Replace your-notion-integration-key with the API key from step 1.

Setup Instructions

Claude Desktop: Settings > Advanced > Model Context Protocol
Cursor AI: Settings > AI > MCP Servers
Claude.ai (Web): Profile > Settings > API & Integrations > Model Context Protocol

Available Tools

The server provides tools for interacting with Notion:

Search: Find pages or databases
Databases: Query and retrieve database entries
Pages: Create, retrieve, and update pages
Blocks: Manage content blocks (paragraphs, lists, etc.)
Users: List users and get user information
Comments: Create and list comments
Link Previews: Create link previews for URLs

Alternative Setup Methods

Using Environment Variables

Instead of passing the API key directly, you can use a .env file:

Create a .env file with:

NOTION_API_KEY=your-notion-integration-key

Run the server:

npx @ramidecodes/mcp-server-notion@latest -y

JSON Configuration with Environment Variables (for Claude Desktop)

You can also use environment variables in the JSON configuration format:

{
  "mcpServers": {
    "Notion": {
      "command": "npx",
      "args": [
        "@ramidecodes/mcp-server-notion@latest",
        "-y",
        "--api-key=your-notion-integration-key"
      ]
    }
  }
}

Command Line Options

OPTIONS:
  -h, --help              Show help message
  -v, --version           Show version information
  --verbose               Enable verbose logging
  --env-path <path>       Path to .env file
  --api-key <key>         Notion API key
  -y                      Skip confirmation prompts

Troubleshooting

If you encounter "Failed to create client" errors:

On Windows, try using cmd /c before the npx command
On macOS/Linux, try using the full path to npx
Test the command in a terminal before adding it to your AI assistant

Common Issues

"No access to resource" errors: Make sure you've shared the specific Notion page or database with your integration (see step 2)
Integration not appearing in share menu: Try refreshing the page or restarting your browser
Limited capabilities: Check that your integration has the appropriate capabilities enabled in the Notion integration settings

Features

Full Notion API support through the official SDK
MCP compliant for seamless AI integration
Comprehensive tools for all Notion operations
Robust error handling with detailed messages
Easy configuration with environment variables
