The Notion MCP Server acts as a bridge between your Notion workspace and ChatGPT, enabling AI models to interact with your Notion content through a Model Context Protocol (MCP) server. It allows users to define exactly which Notion pages ChatGPT can access, ensuring privacy and control. The server exposes two primary tools: 'search' for finding relevant Notion pages and 'fetch' for retrieving their full content, including blocks. Built with FastMCP and supporting OAuth, it offers a secure and efficient way to integrate your Notion knowledge base directly into AI workflows.
