computer-agent-mcp

A black-box desktop automation MCP server — give it a task, it handles the screenshots, coordinates, and clicks internally, and returns the result.

中文说明

How It Works

Unlike typical computer-use tools that expose raw screenshots to the host agent, computer-agent-mcp runs the entire vision loop server-side:

1. Captures the current screen

2. Sends the screenshot + task context to an internal vision model

3. Receives observations, action plans, and coordinate mappings

4. Executes actions locally with visible mouse trajectories

5. Repeats until the task is done — then returns a structured result

The host agent never sees a screenshot. It just sends a task and gets back a result.

Features

• Task-level API — one call to complete a desktop task, no multi-turn screenshot protocol

• Server-side vision loop — screenshots, coordinate mapping, and action execution all handled internally

• Human override detection — stops immediately when a real user touches the keyboard or mouse

• Step-by-step debug recording — full event timeline, screenshots, and model request/response logs

• Works with any OpenAI-compatible vision model — bring your own endpoint and model

Quick Start

Prerequisites

• Windows

• Python >= 3.11

• An OpenAI-compatible API key

Install & Run

The quickest way to start:

uvx computer-agent-mcp \
  --api-key sk-... \
  --base-url https://api.openai.com/v1 \
  --model gpt-5.4

Or install via pip:

pip install computer-agent-mcp
computer-agent-mcp \
  --api-key sk-... \
  --base-url https://api.openai.com/v1 \
  --model gpt-5.4

MCP Host Configuration

Add to your MCP client config (e.g. Claude Desktop, Cursor, etc.):

{
  "mcpServers": {
    "computer-agent": {
      "command": "uvx",
      "args": [
        "computer-agent-mcp",
        "--base-url",
        "https://api.openai.com/v1",
        "--model",
        "gpt-5.4"
      ],
      "env": {
        "COMPUTER_AGENT_OPENAI_API_KEY": "sk-..."
      }
    }
  }
}

Tools

computer_use_task

Run a stateless black-box desktop task.

Returns structured result with status (completed / blocked / failed), summary, result, memory, and trace.

computer_list_displays

List available displays. Useful for multi-monitor setups.

Configuration

All CLI parameters can also be set via environment variables:

Enable debug recording with COMPUTER_AGENT_DEBUG=1. See REFERENCE.md for the full configuration reference and detailed runtime semantics.

Development

pip install -e .[dev]
pytest

Platform Support

Currently Windows only. The server will start on other platforms but desktop tool calls will fail.
