​
Prerequisites

Before using OpenHands CLI with ACP, you must first install and configure the CLI:
  1. Install OpenHands CLI by following the CLI Mode installation instructions
  2. Configure your LLM settings using the /settings command
The ACP integration will reuse the credentials and configuration from your CLI settings.

​
What is the Agent Client Protocol (ACP)?

The Agent Client Protocol (ACP) is a standardized communication protocol that enables code editors and IDEs to interact with AI agents. ACP defines how clients (like code editors) and agents (like OpenHands) communicate through a JSON-RPC 2.0 interface. For more details about the protocol, see the ACP documentation.

​
ACP Support in OpenHands CLI

OpenHands CLI implements the Agent Client Protocol, allowing you to use OpenHands directly within your code editor. When you configure your editor to use openhands acp, it will communicate with OpenHands through the standardized ACP interface. OpenHands CLI currently supports the following ACP features: ✅ Implemented:
  • Initialization - version negotiation and capability exchange
  • Session Setup - creating new sessions and loading existing ones
  • Content - including embedded content and resources
  • Prompt Turns - sending prompts and receiving responses (permissions coming soon)
  • Tool Calls - executing tools and returning results
  • Agent Plan - sharing agent’s planned actions
🚧 Coming Soon:
  • Confirmation - user authorization for tool calls
  • Slash Commands - for changing confirmation mode
Feel free to open issues on the OpenHands-CLI repo if you have feature requests or encounter any problems.
