---
Use the [Agent Client Protocol (ACP)](https://agentclientprotocol.com/) to build
clients that connect to goose's agent runtime, tools, extensions, and configured
models. These clients can be code editors, desktop, web, or mobile apps,
automated services, or other custom integrations.

For methods provided by goose in addition to the standard ACP methods, see the
[goose ACP Reference](https://goose-docs.ai/docs/gdk/acp/reference).

## Install

Choose one installation method based on how your ACP client runs goose.

### Install the goose CLI

Install the [goose CLI](https://funcoding.ai/agents/goose/getting-started/installation/) to configure a client
to launch `goose acp` or to run `goose serve` yourself.

### Install from the ACP Registry

Supported ACP clients can install and manage goose for you through the
[goose entry in the ACP Registry](https://agentclientprotocol.com/get-started/registry#goose).
This does not require a separate goose CLI installation.

## Run the agent

### Connect over stdio

Configure your ACP client to launch goose as a subprocess with this command:

```bash
goose acp
```

The client communicates with goose through stdin and stdout and manages the
process for the lifetime of the connection.

### Connect over HTTP or WebSocket

Run `goose serve` when your ACP client connects over HTTP or WebSocket:

```bash
GOOSE_SERVER__SECRET_KEY='a-long-random-secret' goose serve
```

`GOOSE_SERVER__SECRET_KEY` sets the secret your clients use to authenticate.
When you run `goose serve` directly, it listens on `127.0.0.1:3284` and exposes
the ACP endpoint at `/acp`. To use a different address, pass `--host` and
`--port`.

#### Authentication

HTTP clients authenticate with the `X-Secret-Key` header. WebSocket clients can
use the same header, but browser-based WebSocket clients must pass the secret in
the `?token=` query parameter. Requests without the correct secret receive a
`401 Unauthorized` response.

<div class="callout callout-warning">

**Local development only**

Passing `--dangerously-unauthenticated` starts `goose serve` without
authentication. Use it only when the server is isolated from untrusted traffic.

</div>

#### Browser origins

Most clients do not need to configure origins. Browser-based clients served from
a non-loopback origin must allow that origin when starting goose. To allow both
a local development client and a deployed web client, specify both origins:

```bash
GOOSE_SERVER__SECRET_KEY='a-long-random-secret' goose serve \
  --allowed-origin 'http://localhost:5173' \
  --allowed-origin 'https://app.example'
```

Specifying any `--allowed-origin` values replaces the default loopback origins,
so include every origin your clients need, including localhost origins used for
development. Origins must match exactly, including the scheme and port.

For remote deployment, TLS, and certificate setup, see
[Running a Remote goose Server](https://funcoding.ai/agents/goose/guides/remote-goose-server/).
Run `goose serve --help` for the complete list of options.

## ACP client examples

### Clients over stdio

Browse the [official ACP clients directory](https://agentclientprotocol.com/get-started/clients)
for clients that can run local ACP agents. For a worked example of installing
and configuring goose as a stdio agent, see the
[Zed setup example](https://funcoding.ai/agents/goose/gdk/acp/zed/).

### goose Desktop over WebSocket

[goose Desktop](https://github.com/aaif-goose/goose/tree/main/ui/desktop) is an
ACP client that uses WebSocket. It starts `goose serve` locally on an available
loopback port and connects to its `/acp` endpoint over WebSocket.
