NotionMCP — AI-Powered Notion Assistant via MCP

NotionMCP is a Modular Context Protocol (MCP) server that exposes advanced Notion search, reading, summarization, and emotion-analysis tools to any MCP-compatible LLM client such as Claude Desktop.

This project turns your Notion workspace into an intelligent, queryable knowledge system, giving your AI assistant the ability to:

• Search pages and databases with precision
• Read and extract block-level content
• Summarize large or complex Notion pages
• Analyze sentiment/emotion of page text
• Build AI workflows on top of your Notion data
• Operate securely using the MCP standard

It is built for:

• Developers
• Researchers
• Data science teams
• Knowledge-intensive organizations
• Anyone wanting an AI agent deeply integrated with Notion

Configuring Claude Desktop

Add the following to:

claude_desktop_config.json

{
  "mcpServers": {
    "NotionMCPServer": {
      "command": "uv",
      "args": [
        "--directory",
        "your-own-server-file-directory",
        "run",
        "server.py"
      ]
    }
  }
}

Restart Claude Desktop. You should now see all Notion tools available under the MCP Tools menu.

Environment Variables

Create a .env file or export environment variables:

NOTION_API_KEY=secret_notion-api
HTTP-TIMEOUT=60

Your Notion integration must be shared with the pages or workspace you want to read.

Usage Examples

Ask Claude:

• “Search Notion for pages about convolution.”
• “Summarize the Deep Learning page in 200 words.”
• “Extract the first 20 lines of the Metrics page.”
• “Analyze the emotional tone of the Vision page.”

Claude will automatically call MCP tools such as:

• search
• iter_search
• get_page_text
• summarize_page_text
• get_page_sentiment
