Install Halal Terminal in ECA

What you need first

• ECA, installed.
• Nothing else: the server runs on its publisher's machines and ECA connects to it.
• Your own value for YOUR_X_API_KEY.

Steps

1. Open ~/.codex/config.toml, or create it. The Codex CLI, its IDE extension and the ChatGPT desktop app share this file.
2. Add this table at the end of the file.

{
  "mcpServers": {
    "mcp": {
      "url": "https://mcp.halalterminal.com/sse",
      "headers": { "X-API-Key": "YOUR_X_API_KEY" }
    }
  }
}

3. Replace YOUR_X_API_KEY with your own value.
4. Save the file and restart ECA.

Check it worked

Ask ECA: List the tools of mcp.

If it does not start

401 Unauthorized

The endpoint wants a sign-in or a key. Sign in when ECA asks, or check the value in place of the placeholder.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
