Notion MCP Server

A Model Context Protocol (MCP) server that connects Claude and other AI assistants to your Notion workspace. This integration allows AI assistants to interact with your Notion databases, pages, and blocks.

What is this?

This tool acts as a bridge between AI assistants (like Claude) and your Notion workspace. It allows the AI to:

• View and search your Notion databases
• Create and update pages
• Manage content blocks
• And much more!

Step-by-Step Setup Guide

Prerequisites

• Node.js (version 14 or higher)
• A Notion account
• Claude Desktop app (if using with Claude)

1. Getting Your Notion API Key

1. Go to https://www.notion.so/my-integrations

2. Click the blue "+ New integration" button

3. Fill in the details:

4. Click "Submit"

5. On the next page, find the "Internal Integration Token" section

6. Click "Show" and copy the token (it starts with `secret_`)

2. Setting Up This Server

Download the Repository

Option A: Download as ZIP (Recommended for beginners)

1. Go to the GitHub repository: https://github.com/Sjotie/notionMCP/

2. Click the green "Code" button at the top right

3. Select "Download ZIP"

4. Once downloaded, extract the ZIP file to a location on your computer

Option B: Clone with Git (For users familiar with Git)

1. Open a command prompt or terminal

2. Navigate to where you want to store the repository

cd path/to/desired/location

3. Clone the repository

git clone https://github.com/Sjotie/notionMCP/

Navigate to the Project Directory

After downloading or cloning, you need to navigate to the project folder using the `cd` (change directory) command:

If you downloaded the ZIP (Option A):

1. Open a command prompt or terminal

2. Use the `cd` command to navigate to where you extracted the ZIP file:

cd path/to/extracted/folder/notionMCP

For example:

If you cloned with Git (Option B):

1. The repository should have been cloned into a folder named "notionMCP"

2. If you're still in the same terminal window after cloning, simply type:

cd notionMCP

How to know you're in the right directory:

• After using the `cd` command, you can check your current location:
  • On Windows: Type `dir` and press Enter - you should see files like `server.js`
  • On Mac: Type `ls` and press Enter - you should see files like `server.js`

Install Dependencies

Once you're in the notionMCP directory, install the required dependencies:

npm install

This will install all the necessary Node.js packages. You should see a progress bar and eventually a message indicating the installation is finished. It might say something along the lines of "X Packages are looking for funding" - this is completely normal and means it worked.

3. Connecting to Notion Pages

For security, Notion requires you to explicitly grant access to each page or database:

1. Open Notion and navigate to a page or database you want the AI to access

2. Click the "•••" (three dots) in the top-right corner

3. Select "Add connections"

4. Find and select the integration you created earlier

5. Repeat for any other pages or databases you want to make accessible

4. Connecting to Claude Desktop

1. Locate your Claude Desktop configuration file:

(Type this path in File Explorer address bar)

(In Finder, press Cmd+Shift+G and paste this path)

2. Open the file in a text editor. If it doesn't exist, create it with the following content:

{
     "mcpServers": {
       "notion": {
         "command": "node",
         "args": [
           "C:\\path\\to\\notion-mcp-server\\server.js"
         ],
         "env": {
           "NOTION_API_KEY": "your_notion_api_key_here"
         }
       }
     }
   }

3. Replace:

4. Save the file and restart Claude Desktop

5. Testing the Connection

1. Start a new conversation in Claude

2. Ask Claude to interact with your Notion workspace, for example:
