Notion MCP — Knowledge Base Server for AI Agents

What it is

Notion MCP is a Model Context Protocol server that connects AI agents like Claude Code to Notion workspaces. It enables searching pages, reading content, creating documents, and managing databases through natural language commands. Once configured, your AI agent can query your entire Notion knowledge base as context for its work.

It is designed for developers and teams who store documentation, specs, and knowledge in Notion and want their AI tools to access that context directly.

How it saves time or tokens

The token estimate for this workflow is 2,400 tokens. Instead of manually copying Notion content into prompts, the MCP server lets your agent pull the relevant pages on demand. This keeps context fresh and avoids stale copy-paste. The search functionality means the agent finds the right page without you specifying exact URLs.

How to use

1. Create a Notion integration at notion.so/my-integrations and get your API key
2. Share relevant pages with your integration
3. Add the MCP server config to your .mcp.json
4. Restart your AI tool

Example

{
  "mcpServers": {
    "notion": {
      "command": "npx",
      "args": ["-y", "@anthropic/mcp-notion"],
      "env": {
        "NOTION_API_KEY": "ntn_your_integration_token"
      }
    }
  }
}

Once configured, ask your agent:

'Search my Notion for the API design spec'
'Create a new page in the Engineering database with today\'s standup notes'
'Read the onboarding checklist and summarize the steps'

Common pitfalls

• Pages must be explicitly shared with your integration; the agent cannot access pages that have not been shared
• The integration token has workspace-level scope; do not share it in public repositories
• Large Notion databases with thousands of rows may hit API rate limits; use filters to narrow queries
