JetBrains

​

Prerequisites

• A JetBrains IDE with the AI Assistant plugin and AI Chat available.

​

Setup

1

Open AI Chat

Click the AI Chat icon in the right-hand tool window bar.

2

Open the agent selector

Click the agent selector in the AI Chat footer to see the list of available agents.

3

Install Devin from the ACP Registry

Choose Install From ACP Registry…, search for Devin, and click Install. Devin is added to the list of available agents.

4

Log in to Devin (optional)

The first time you connect, you may be prompted to authenticate. Follow the prompt to log in to your Devin account.

5

Start chatting with Devin

Select Devin in the agent selector and send a message to start a session.

​

Manual setup (custom ACP)

​

Prerequisites

• Devin CLI installed and authenticated. If you haven’t installed it yet, follow the Quickstart, then run devin auth login.
• The absolute path to the devin binary. You can find it with:
  which devin
  
  This typically resolves to something like ~/.local/bin/devin.

1

Open AI Chat

Click the AI Chat icon in the right-hand tool window bar.

2

Add a custom agent

Click the three-dots menu in the top-right of the AI Chat panel, then choose Add Custom Agent. This opens the acp.json configuration file.

3

Configure the Devin agent

Add Devin to the agent_servers block in acp.json. Set command to the absolute path of your devin binary (from which devin) and pass acp as the only argument:

acp.json

{
  "default_mcp_settings": {},
  "agent_servers": {
    "devin": {
      "command": "/home/you/.local/bin/devin",
      "args": ["acp"]
    }
  }
}

Save the file. Devin now appears as a selectable agent in AI Chat.

4

Start chatting with Devin

Select devin as the agent in AI Chat and send a message to start a session. The first time you connect, you may be prompted to authenticate; Devin uses the credentials from devin auth login (or WINDSURF_API_KEY if set).

​

Managing the integration

• Reset ACP Authentication — clear stored ACP credentials and re-authenticate.
• Get ACP Logs — open the ACP logs, useful for debugging connection issues or inspecting what the agent is doing under the hood.

​

Notes and limitations

• Devin CLI’s terminal/shell output is surfaced through JetBrains AI Chat’s ACP rendering, which differs from the native Devin CLI terminal UI. Some richer interactions are only available in the standalone CLI.
• The devin acp subcommand is intended to be launched by an ACP-aware client (like JetBrains AI Chat) as a subprocess — it speaks JSON-RPC over stdio and is not meant to be run interactively. See devin acp in the command reference.
