Connect Codex to Floxar

The Codex command line, the Codex IDE extension and the ChatGPT desktop app share one configuration, so you add Floxar once. Codex identifies itself to Floxar with its own Client ID Metadata Document, so you enter no client ID or secret.

Use Codex 0.151.0 or later; earlier releases do not present the identity Floxar recognises. Leave Codex's oauth_resource override unset.

Before you start, make sure MCP is on for your account and have your account URL ready. Connecting an AI client explains both, and what the sign-in and consent page show.

Add Floxar​

  1. Add the server from your terminal. Codex starts the sign-in at once and opens your browser.

    codex mcp add acme-floxar --url https://mcp.floxar.com/a/<account_id>

  2. If the browser did not open, run codex mcp login acme-floxar. Sign in to Floxar, confirm the account and allow the connection.

  3. In the ChatGPT desktop app, open Settings, then MCP servers, then Add server instead, choose Streamable HTTP and paste your account URL. Save it, select Restart, then Authenticate.

What the sign-in looks like​

The consent page shows Codex under Floxar's label for it. The command line runs on your computer, so the connection returns to a local address, and the consent page says so. Codex asks for the three capabilities and to stay connected.

Known limits​

  • Codex may use your ChatGPT connection. If the same account is also a ChatGPT connector on your ChatGPT account, Codex may route its calls through that connector, and the two share one connection: revoking it disconnects both.
  • codex mcp logout is local only. The connection stays active in Floxar until you or an account admin end it there (see "Disconnecting and revoking" in Connecting an AI client).
  • After a revocation, the server may silently disappear from a Codex session. Run codex mcp login acme-floxar to connect again.
  • Codex's own approval policy applies. In non-interactive runs, Codex's approval setting can refuse write tools before they reach Floxar; that is a Codex setting, not a Floxar one.
  • Adding access later means reconnecting. Run codex mcp login acme-floxar again; the new consent lists the capabilities the connection gets.
