# agent-gui-server
|
|
|
|
Desktop GUI automation MCP server — text-based Agents (claude-code, qimingcode) call it via MCP protocol to perform screenshot recognition + keyboard/mouse simulation.
|
|
|
|
## Features
|
|
|
|
- **14 MCP Tools**: 13 atomic operations + 1 high-level `gui_execute_task`
|
|
- **Dual Transport**: Streamable HTTP (primary) + stdio (backup)
|
|
- **Agent Loop**: pi-mono Agent with three-layer memory management
|
|
- **Multi-Model Coordinate Support**: Anthropic, OpenAI, Google (Gemini yx auto-swap)
|
|
- **Safety**: Hotkey blacklist, audit log, stuck detection
|
|
- **Cross-Platform**: macOS, Windows, Linux
|
|
|
