How it works.

1. Open chatgpt.com/plugins in a browser on your computer.
2. Tap +, then Add custom MCP server.
3. Name it CarBit and, under Connection, paste the address above into the URL field.
4. For authentication choose OAuth or no authentication, not just OAuth. That way you try it without an account and only sign in when you publish; with plain OAuth, ChatGPT shows you nothing until you sign in.
5. Read the warning, tap I understand and want to continue, then Create as a plugin.
6. Install CarBit from your list of plugins. In a new conversation type @, pick CarBit and send your first message.

Access depends on your account and workspace. Setup help (opens in a new tab)

2. Tap + Add, then Add custom connector.
3. Name it CarBit, paste the address above as the URL and tap Continue.
4. Under Authentication choose Sign in when needed, leave the rest as it is and tap Add. That way you try it without an account and only sign in when you publish.
5. In a new conversation, tap + at the bottom left, then Connectors, turn CarBit on and write your first message.
