- Built-in name:
mux - Default command:
npx -y mux acp - Upstream: https://mux.coder.com/integrations/acp
acpx mux starts coder/mux through its ACP stdio bridge (mux acp). mux acp auto-starts an in-process mux server, so a separate mux server is not required.
Configure at least one model provider before prompting (for example ANTHROPIC_API_KEY, OPENAI_API_KEY, or OPENROUTER_API_KEY); see https://mux.coder.com/config/providers. To target a remote mux server, override the command with mux acp --server-url <url> --auth-token <token> (or set MUX_SERVER_URL / MUX_SERVER_AUTH_TOKEN).
