Using goose in ACP Clients

Client applications that support the Agent Client Protocol (ACP) can connect natively to goose. This integration allows you to seamlessly interact with goose directly from the client.

Experimental Feature

ACP is an emerging specification that enables clients to communicate with AI agents like goose. This feature has limited adoption and may evolve as the protocol develops.

How It Works​

After you configure goose as an agent in the ACP client, you gain access to goose's core agent functionality, including its extensions and tools.

The client manages the goose lifecycle automatically, including:

  • Initialization: The client runs the goose acp command to initialize the connection
  • Communication: The client communicates with goose over stdio using JSON-RPC
  • Multiple Sessions: The client manages multiple concurrent goose conversations simultaneously
Session Persistence

ACP sessions are saved to goose's session history where you can access and manage them using goose. However, these sessions aren't persisted in ACP clients, so you'll need to start a new conversation each time you restart the client.

Setup in ACP Clients​

Any editor or IDE that supports ACP can connect to goose as an agent server. Check the official ACP clients list for available clients with links to their documentation.

Example: Zed Editor Setup​

ACP was originally developed by Zed. Here's how to configure goose in Zed:

1. Prerequisites​

Ensure you have both Zed and goose CLI installed:

  • Zed: Download from zed.dev

  • goose CLI: Follow the installation guide

    • ACP support works best with version 1.14.2 or later - check with goose --version.

    • Temporarily run goose acp to test that ACP support is working:

      ~ goose acp
      Goose ACP agent started. Listening on stdio...

      Press Ctrl+C to exit the test.

2. Configure goose as a Custom Agent​

Add goose to your Zed settings:

  1. Open Zed
  2. Press Cmd+Option+, (macOS) or Ctrl+Alt+, (Linux/Windows) to open the settings file
  3. Add the following configuration:
{
  "agent_servers": {
    "goose": {
      "command": "goose",
      "args": ["acp"],
      "env": {}
    }
  },
  // more settings
}

You should now be able to interact with goose directly in Zed. Your ACP sessions use the same extensions that are enabled in your goose configuration, and your tools (Developer, Computer Controller, etc.) work the same way as in regular goose sessions.

3. Start Using goose in Zed​

  1. Open the Agent Panel: Click the sparkles agent icon in Zed's status bar
  2. Create New Thread: Click the + button to show thread options
  3. Select goose: Choose New goose to start a new conversation with goose
  4. Start Chatting: Interact with goose directly from the agent panel

Advanced Configuration​

By default, goose will use the provider and model defined in your configuration file. You can override this for specific ACP configurations using the GOOSE_PROVIDER and GOOSE_MODEL environment variables.

The following Zed settings example configures two goose agent instances. This is useful for:

  • Comparing model performance on the same task
  • Using cost-effective models for simple tasks and powerful models for complex ones
{
  "agent_servers": {
    "goose": {
      "command": "goose",
      "args": ["acp"],
      "env": {}
    },
    "goose (GPT-4o)": {
      "command": "goose",
      "args": ["acp"],
      "env": {
        "GOOSE_PROVIDER": "openai",
        "GOOSE_MODEL": "gpt-4o"
      }
    }
  },
  // more settings
}
