Notion MCP Server

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

1. Go to https://www.notion.so/my-integrations
2. Create a new integration
3. 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:

1. Navigate to the Notion page or database you want to access through the integration
2. Click the "Share" button in the top-right corner
3. In the "Add people, groups, or integrations" field, select your integration from the dropdown list
4. Click "Invite"
5. 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:
