adal-acp

ACP (Agent Client Protocol) bridge for AdaL CLI — enables AdaL as a coding agent inside Zed.

How it works

This bridge implements the Agent Client Protocol over stdio (newline-delimited JSON-RPC 2.0). When Zed sends a prompt, the bridge spawns adal -q "..." -o stream-json --yolo and translates AdaL's output events into ACP session updates.

Zed ←→ (stdio/JSON-RPC) ←→ adal-acp ←→ (spawn) ←→ adal CLI

Setup

Prerequisites

• Node.js ≥ 18
• AdaL CLI installed (npm i -g adal-cli or brew install adal)

Install

cd adal-acp
npm install

Configure Zed

Add to your Zed settings.json (cmd+,):

{
  "agent_servers": {
    "adal": {
      "type": "custom",
      "command": "node",
      "args": ["/Volumes/990Pro2TB/OtherProjects/adal-acp/index.mjs"],
      "env": {
        "ADAL_BIN": "/opt/homebrew/bin/adal"
      }
    }
  }
}

Or, if you npm link the package globally:

{
  "agent_servers": {
    "adal": {
      "type": "custom",
      "command": "adal-acp"
    }
  }
}
