hi @DavidLiu and welcome to Cursor Forum.

You should be able to use ACP in the lastest CLI version: 2026.03.11-6dfa30c

Please update agent with agent update and then try to see if agent help acp works.

The output should then be

Usage: agent acp [options]

Start the Cursor Agent as an ACP (Agent Client Protocol) server

Options:
  -h, --help  Display help for command

ok, very good
