Overview

What is Notion MCP Server?

Notion MCP Server is a Model Context Protocol (MCP) server implementation for Notion integration. It provides a standardized interface for interacting with Notion’s API and is compatible with Claude Desktop and other MCP clients.

How to use Notion MCP Server?

Install via Smithery (npx -y @smithery/cli install @ccabanillas/notion-mcp --client claude) or manually by cloning the repository, creating a virtual environment, installing dependencies (uv pip install -e . or pip install -e .), and setting a NOTION_API_KEY environment variable in a .env file. Run python -m notion_mcp to test. For Claude Desktop, configure claude_desktop_config.json with the full path to the Python executable and the -m notion_mcp argument.

Frequently asked questions

What does Notion MCP Server do?

It acts as a bridge between MCP clients (like Claude Desktop) and Notion’s API, allowing you to perform database queries, page operations, and workspace searches using a standardized protocol.

How do I get a Notion API key?

Go to https://www.notion.so/my-integrations, create a new integration with appropriate read/write capabilities, and copy the token. Then add it as `NOTION_API_KEY` in a `.env` file in the project root.

What runtime and dependencies are required?

You need Python (with `uv` or standard `venv`), httpx, Pydantic v2, and MCP 1.6.0. The server uses asynchronous HTTP requests via httpx.

Why am I getting connection or permission errors?

Check that your Notion API key is correct and that you have internet access. Also ensure you have shared the target databases with your integration from the database’s “Share” menu.

How does Notion MCP Server communicate with clients?

The server uses the Model Context Protocol (MCP) over standard input/output (stdio), as shown by the `command` and `args` configuration in `claude_desktop_config.json`.
