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.

While we limit the scope of Notion API's exposed (for example, you will not be able to delete databases via MCP), there is a non-zero risk to workspace data by exposing it to LLMs. Security-conscious users may want to further configure the Integration's Capabilities.

For example, you can create a read-only integration token by giving only "Read content" access from the "Configuration" tab:

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

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

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"

You may also reference content ID directly

Get the content of page 1a6b35e6e67f802fa7e1d27686f017f2
