Notion MCP Server

A Model Context Protocol (MCP) server that provides AI assistants (Claude, Cursor, etc.) with a comprehensive interface to the Notion API. Supports both static API keys and OAuth2 authentication.

Overview

notion-mcp allows your AI assistant to directly interact with your Notion workspace. It enables powerful natural language queries like:

• "Search for all pages mentioning 'Q2 roadmap'."
• "Show me the contents of our team wiki page."
• "Query the 'Tasks' database for items assigned to me."
• "List all users in the workspace."

Features

• OAuth2 Support: Browser-based OAuth flow with automatic token refresh, powered by @vineethnkrishnan/oauth-core.
• Static Token Support: Use a Notion integration token for simple setups.
• Modular Architecture: Built with clean layered design for high maintainability.
• Type-Safe: Fully implemented in TypeScript with Zod schema validation.
• Comprehensive Coverage: Full access to Pages, Databases, Search, and Users.

Installation

Using npx (Recommended)

No installation required. Run directly:

npx -y @vineethnkrishnan/notion-mcp

Global Install

npm install -g @vineethnkrishnan/notion-mcp
notion-mcp

From Source

git clone https://github.com/vineethkrishnan/mcp-pool.git
cd mcp-pool
npm install
npm run build

Configuration

To use this server with an MCP client like Claude Desktop, add to your MCP client configuration file:

| Platform | Config file path | |----------|-----------------| | macOS | ~/Library/Application Support/Claude/claude_desktop_config.json | | Windows | %APPDATA%\Claude\claude_desktop_config.json | | Linux | ~/.config/Claude/claude_desktop_config.json |

Using a Static API Key

{
  "mcpServers": {
    "notion": {
      "command": "npx",
      "args": ["-y", "@vineethnkrishnan/notion-mcp"],
      "env": {
        "NOTION_API_KEY": "ntn_..."
      }
    }
  }
}

Using OAuth2

{
  "mcpServers": {
    "notion": {
      "command": "npx",
      "args": ["-y", "@vineethnkrishnan/notion-mcp"],
      "env": {
        "NOTION_CLIENT_ID": "abc12345-...",
        "NOTION_CLIENT_SECRET": "secret_abc12345..."
      }
    }
  }
}

Then run the OAuth setup:

notion-mcp auth login

This will:

1. Open a browser window where you'll log in to Notion and authorize the app
2. After you approve, the browser will show a success message
3. Your tokens are saved locally at ~/.mcp-pool/notion/ and refresh automatically

Environment Variables

| Variable | Required | Default | Description | |----------|----------|---------|-------------| | NOTION_API_KEY | No* | - | Static Notion integration token. | | NOTION_CLIENT_ID | No* | - | OAuth2 client ID. | | NOTION_CLIENT_SECRET | No* | - | OAuth2 client secret. | | NOTION_VERSION | No | 2022-06-28 | Notion API version. |

*Either NOTION_API_KEY or both NOTION_CLIENT_ID and NOTION_CLIENT_SECRET must be provided.

Getting Your Credentials

Option A: Integration Token (Simpler)

1. Go to notion.so/my-integrations
2. Click New integration
3. Give it a name, select your workspace, and click Submit
4. Copy the Internal Integration Secret (starts with ntn_)
5. In Notion, share the pages/databases you want to access with your integration

Option B: OAuth App

1. Go to notion.so/my-integrations
2. Create an integration and enable Public integration under Distribution
3. Copy the OAuth client ID and OAuth client secret
