Connect Notion to Codex

Search, read and write Notion from Codex. Arlet links the two through one MCP connection and takes care of keys and authentication.

Enable Notion in ArletCodex connection guide (docs)

Arlet makes Notion's official MCP server available from the AI client you already use. There is no integration to create on the Notion side. Signing in completes the connection.

Beyond searching and reading pages, the AI can create pages, update databases and leave comments. The available tools are exactly those provided by Notion's official server.

How to connect Notion to Codex

  1. 1

    In the Arlet dashboard, open Integrations → Add an integration and choose Notion. Sign in with Link Notion, name the connection and click Create.

  2. 2

    In your terminal, run codex mcp add arlet --url https://mcp.arlet.dev/mcp/ to add Arlet as an MCP server.

  3. 3

    Codex detects OAuth support and opens your browser. Sign in with Google and click Allow on the consent screen.

  4. 4

    Once connected, both the CLI and the IDE extension can call Arlet tools (the configuration is shared).

If the browser does not open, run codex mcp login arlet to redo the authentication.
