This project implements anMCP server for theNotion API.

Go tohttps://www.notion.so/profile/integrations and create a newinternal 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'sCapabilities.

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

Ensure relevant pages and databases are connected to your integration.

To do this, visit theAccess tab in your internal integration settings. Edit access and select the pages you'd like to use.

Alternatively, you can grant page access individually. You'll need to visit the target page, and click on the 3 dots, and select "Connect to integration".

Cursor & Claude:

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

Option 1: Using NOTION_TOKEN (recommended)

{"mcpServers":{"notionApi":{"command":"npx","args":["-y","@notionhq/notion-mcp-server"],"env":{"NOTION_TOKEN":"ntn_****"}}}}

Option 2: Using OPENAPI_MCP_HEADERS (for advanced use cases)

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

Zed

Add the following to yoursettings.json

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

There are two options for running the MCP server with Docker:

Add the following to your.cursor/mcp.json orclaude_desktop_config.json:

Using NOTION_TOKEN (recommended):

{"mcpServers":{"notionApi":{"command":"docker","args":["run","--rm","-i","-e","NOTION_TOKEN","mcp/notion"],"env":{"NOTION_TOKEN":"ntn_****"}}}}

Using OPENAPI_MCP_HEADERS (for advanced use cases):

{"mcpServers":{"notionApi":{"command":"docker","args":["run","--rm","-i","-e","OPENAPI_MCP_HEADERS","mcp/notion"],"env":{"OPENAPI_MCP_HEADERS":"{\"Authorization\":\"Bearer ntn_****\",\"Notion-Version\":\"2022-06-28\"}"}}}}

This approach:

• Uses the official Docker Hub image
• Properly handles JSON escaping via environment variables
• Provides a more reliable configuration method

You can also build and run the Docker image locally. First, build the Docker image:

docker compose build

Then, add the following to your.cursor/mcp.json orclaude_desktop_config.json:

Using NOTION_TOKEN (recommended):

{"mcpServers":{"notionApi":{"command":"docker","args":["run","--rm","-i","-e","NOTION_TOKEN=ntn_****","notion-mcp-server"]}}}

Using OPENAPI_MCP_HEADERS (for advanced use cases):

{"mcpServers":{"notionApi":{"command":"docker","args":["run","--rm","-i","-e","OPENAPI_MCP_HEADERS={\"Authorization\": \"Bearer ntn_****\", \"Notion-Version\": \"2022-06-28\"}","notion-mcp-server"]}}}

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

To install Notion API Server for Claude Desktop automatically viaSmithery:

npx -y @smithery/cli install @makenotion/notion-mcp-server --client claude

The Notion MCP Server supports two transport modes:

The default transport mode uses standard input/output for communication. This is the standard MCP transport used by most clients like Claude Desktop.

# Run with default stdio transportnpx @notionhq/notion-mcp-server# Or explicitly specify stdionpx @notionhq/notion-mcp-server --transport stdio

For web-based applications or clients that prefer HTTP communication, you can use the Streamable HTTP transport:

# Run with Streamable HTTP transport on port 3000 (default)npx @notionhq/notion-mcp-server --transport http# Run on a custom portnpx @notionhq/notion-mcp-server --transport http --port 8080# Run with a custom authentication tokennpx @notionhq/notion-mcp-server --transport http --auth-token"your-secret-token"

When using Streamable HTTP transport, the server will be available athttp://0.0.0.0:<port>/mcp.

The Streamable HTTP transport requires bearer token authentication for security. You have three options:

Option 1: Auto-generated token (recommended for development)

npx @notionhq/notion-mcp-server --transport http

The server will generate a secure random token and display it in the console:

Generated auth token: a1b2c3d4e5f6789abcdef0123456789abcdef0123456789abcdef0123456789abUse this token in the Authorization header: Bearer a1b2c3d4e5f6789abcdef0123456789abcdef0123456789abcdef0123456789ab

Option 2: Custom token via command line (recommended for production)

npx @notionhq/notion-mcp-server --transport http --auth-token"your-secret-token"

Option 3: Custom token via environment variable (recommended for production)

AUTH_TOKEN="your-secret-token" npx @notionhq/notion-mcp-server --transport http

The command line argument--auth-token takes precedence over theAUTH_TOKEN environment variable if both are provided.

All requests to the Streamable HTTP transport must include the bearer token in the Authorization header:

# Example requestcurl -H"Authorization: Bearer your-token-here" \     -H"Content-Type: application/json" \     -H"mcp-session-id: your-session-id" \     -d'{"jsonrpc": "2.0", "method": "initialize", "params": {}, "id": 1}' \     http://localhost:3000/mcp

Note: Make sure to set either theNOTION_TOKEN environment variable (recommended) or theOPENAPI_MCP_HEADERS environment variable with your Notion integration token when using either transport mode.

1. Using the following instruction

Comment "Hello MCP" on page "Getting started"

AI will correctly plan two API calls,v1/search andv1/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

Get the content of page 1a6b35e6e67f802fa7e1d27686f017f2

Build

npm run build
