Use Kuro in Codex: add the MCP server and sign in

Codex connects to Kuro as a remote MCP server. You add the endpoint once, sign in once in the browser, and Codex can then call Kuro’s tools. Everything it makes lands in your Kuro library.

Add the server

Run this in a terminal:

codex mcp add kuro --url https://api.meetkuro.com/mcp

There is no API key to paste. Kuro signs in with OAuth, and Codex registers itself with Kuro automatically, so there is no client ID either.

If a browser opened on Kuro after the command, go to step 2. If not, start the sign-in yourself:
```
codex mcp login kuro
```
On a machine with no browser, add --no-browser: Codex prints the sign-in address, and you paste back the address you land on.
On Kuro, sign in (or create an account), review what Codex may do, and approve the connection.
Start Codex:
```
codex
```

Check it worked

codex mcp list shows kuro with OAuth as its auth. Inside Codex, /mcp lists the servers it has active. Then ask for something that costs nothing:

How many Kuro credits do I have left?

One setup, three places

Codex keeps MCP servers in ~/.codex/config.toml. The command above writes this entry, which you can also type by hand:

[mcp_servers.kuro]
url = "https://api.meetkuro.com/mcp"

OpenAI’s documentation states that the ChatGPT desktop app, the Codex CLI and the Codex IDE extension share this configuration, so adding Kuro in one makes it available in the others.

A first job

Three vertical images of a charcoal running shoe on a cracked salt flat at dawn. Cheapest model that does it well. Price it first.

Kuro tells Codex to name the format, the model and the price before it spends, and to read a model’s guide before its first use. Codex starts the images, checks on them until they are ready, and gives you a link to each one in Kuro.

Remove it

codex mcp remove kuro

codex mcp logout kuro clears the stored sign-in and keeps the server. To cut every agent off at once, revoke the connection in Kuro under Settings → Connections.

The commands and the config format come from OpenAI’s Codex MCP documentation and from codex mcp --help.

Everything here runs in the studio.

Every model named on this page is one you can pick from the composer.
