Notion MCP Server

This project implements an MCP server for the Notion API.

Installation

1. Setting up Integration in Notion:

Go to https://www.notion.so/profile/integrations and create a new internal integration or select an existing one.

2. Adding MCP config to your client:

Add the following to your .cursor/mcp.json or claude_desktop_config.json (MacOS: ~/Library/Application\ Support/Claude/claude_desktop_config.json)

{
  "mcpServers": {
    "notionApi": {
      "command": "npx",
      "args": ["-y", "@notionhq/notion-mcp-server"],
      "env": {
        "OPENAPI_MCP_HEADERS": "{\"Authorization\": \"Bearer ntn_****\", \"Notion-Version\": \"2022-06-28\" }"
      }
    }
  }
}

Don't forget to replace ntn_**** with your integration secret. Find it from your integration configuration tab:

3. Connecting content to integration:

Ensure relevant pages and databases are connected to your integration.

To do this, you'll need to visit that page, and click on the 3 dots, and select "Connect to integration".

Examples

1. Using the following instruction

Comment "Hello MCP" on page "Getting started"

AI will correctly plan two API calls, v1/search and v1/comments, to achieve the task

2. Similarly, the following instruction will result in a new page named "Notion MCP" added to parent page "Development"

Add a page titled "Notion MCP" to page "Development"

3. You may also reference content ID directly
