Overview

What is Notion MCP Client?

Notion MCP Client is a Model Context Protocol (MCP) client for interacting with the Notion API, designed for use in AI tools like Claude that support MCP. It can also fall back to a standard HTTP API when MCP is not available.

How to use Notion MCP Client?

Install via pip install notion-mcp (or with MCP support: pip install notion-mcp[mcp]). Configure a .env file with your Notion token and root page ID. Run the CLI with notion-mcp or start the server with notion-mcp-server --host 0.0.0.0 --port 8000. You can also supply a JSON configuration file.

Key features of Notion MCP Client

  • Asynchronous API operations with retry logic
  • Concurrency control to respect Notion API rate limits
  • Environment-based and JSON-based configuration
  • Flexible server implementation with MCP support
  • Falls back to standard HTTP API when MCP is unavailable
  • Supports custom operations like fill_web_url

Use cases of Notion MCP Client

  • Use with Claude to manipulate Notion databases and pages via natural language
  • Automate filling URL fields across pages in selected databases
  • Integrate with any web framework using the NotionRequestHandler class
  • Run as a standalone HTTP server for custom clients

Frequently asked questions

1

What dependencies or runtime are required?

Python 3.x and the packages installed via pip. For MCP support, install with the `[mcp]` extra.

2

What API credentials are needed?

A Notion API token (`NOTION_TOKEN`) and a root page ID (`ROOT_PAGE_ID`) are required, set via environment variables or a JSON configuration file.

3

Where does data live?

Data remains in Notion. The client reads and writes to your Notion workspace through the Notion API; no data is stored locally beyond configuration.

4

What transport protocols are supported?

MCP (Model Context Protocol) when available; otherwise, the server falls back to a standard HTTP API that accepts POST requests at `/notion`.

5

Are there any known limits?

The client uses configurable concurrency limits and retry delays (e.g., `CONCURRENCY_LIMIT=5`, `RETRY_DELAYS=1,3,5`) to respect Notion API rate limits. Only one operation (`fill_web_url`) is documented; more are planned.
