Use Arlet from Codex
OpenAI's coding agent (CLI and IDE extension). Authentication starts as soon as you add it.
Connect Arlet to Codex once and every service and public data source below becomes available from Codex. You connect to Arlet one time, not to each service.
How to connect Arlet to Codex
- 1
In your terminal, run codex mcp add arlet --url https://mcp.arlet.dev/mcp/ to add Arlet as an MCP server.
- 2
Codex detects OAuth support and opens your browser. Sign in with Google and click Allow on the consent screen.
- 3
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.
