This is a known limitation. ACP doesn’t currently support login in JetBrains Remote Development environments because the cursor-agent runs on the remote host, where it can’t open a browser to complete the authentication flow. That’s why the login button fails immediately.

There’s no fix yet. Our team is aware of the issue and the plan is to support a browserless login flow (where the agent prints a URL you can open manually), but it hasn’t been implemented.

In the meantime, you can try SSH’ing into the remote host and running agent login in the terminal. If the CLI detects it can’t open a browser, it should print a URL you can open in your local browser instead. Once authenticated via the CLI, the ACP session in JetBrains should pick up the credentials. This workaround isn’t guaranteed, but it’s worth trying.

If Remote Development isn’t strictly required, using WebStorm locally would let you log in normally.
