Connect Codex - Allocait

Codex uses the same MCP server and the same sign-in as ChatGPT. You add the server from a terminal, then sign in to your Allocait account in your browser.

Add the server

1

Add the server

codex mcp add allocait --url https://api.allocait.app/functions/v1/mcp

2

Sign in

codex mcp login allocait

Codex opens your browser to Allocait’s sign-in and consent screens. Choose Read only or Read and change, then select Allow. See Access for what each allows.

For what the consent screen shows and what to do if a request expires, see Connect ChatGPT. If the sign-in doesn’t start, run codex mcp login allocait --oauth-client-registration dcr. To see the server and its tools, see OpenAI’s Codex guide to MCP servers.

Use a config file

You can also add the server to ~/.codex/config.toml:

[mcp_servers.allocait]
url = "https://api.allocait.app/functions/v1/mcp"

Timeouts

Codex sets its own timeouts for starting a server and for a tool call. See OpenAI’s Codex guide to MCP servers to change them. For what a timeout or sign-in message means, see ChatGPT errors.
