Headless CLI client for stateful Agent Client Protocol (ACP) sessions
openclaw/acpx is a headless command-line client for the Agent Client Protocol, a standard interface for communicating with compatible coding agents. Agents, orchestrators, and developers use it to manage persistent or one-off sessions, permissions, and machine-readable output across tools such as Codex, Claude Code, Gemini CLI, and OpenClaw, with the catalogue containing agents and instructions for those workflows.
This repository also configures its own agents. See what acpx tells them →
