Arlet makes Todoist's official MCP server available from the AI client you already use. Signing in completes the connection.

The AI can search, add, complete and reschedule tasks, manage projects and sections, add comments and reminders, and read productivity stats. The available tools are those provided by Todoist's official server, which is available on the Beginner, Pro and Business plans.

How to connect Todoist to Codex

  1. 1

    In the Arlet dashboard, open Integrations → Add an integration and choose Todoist. Sign in with Link Todoist, 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.
