WinBridgeAgent

中文文档

WinBridgeAgent is an open-source Windows local capability service that implements the Model Context Protocol (MCP) standard, providing traceable Windows system operations for AI assistants such as Claude Desktop, OpenAI, etc.

WinBridgeAgent Pro (Free Download)

In addition to the open-source edition, WinBridgeAgent Pro is now available as a free download.

The Pro edition is designed for users who need a more complete Windows Agent/Node experience, with ongoing improvements toward a more production-ready Windows node (closer to the OpenClaw Node experience).

Key enhancement areas (ongoing) include:

• Stronger media capabilities: camera photo/video capture and screen recording
• Deeper system integration: notifications, location, audio, and related OS features
• More powerful automation: expanded shell command execution with permission/safety controls
• Better production readiness: timeout handling, resource cleanup, error handling, and stability work

Quick Start

Install from MCP Registry

WinBridgeAgent is published on the MCP Registry as io.github.codyard/winbridgeagent. MCP clients that support the registry can install it directly.

Manual Install

1. Download the latest release from GitHub Releases
2. Run WinBridgeAgent-x64.exe (64-bit) or WinBridgeAgent-x86.exe (32-bit)
3. The program appears in the system tray
4. Configure your MCP client (see below)

For OpenClaw + Windows node setup, see windows-node-install.en.md.

MCP Client Configuration

WinBridgeAgent works with any MCP-compatible client. Below are setup instructions for popular clients.

Note: Replace <windows-ip> with the IP address of the Windows PC running WinBridgeAgent (e.g. 192.168.1.100). Use localhost only if the MCP client runs on the same Windows machine.

Claude Desktop

Edit claude_desktop_config.json:

• Windows: %APPDATA%\Claude\claude_desktop_config.json
• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

{
    "mcpServers": {
        "winbridgeagent": {
            "url": "http://<windows-ip>:35182",
            "transport": "http"
        }
    }
}

        },
        "winbridge-office": {
            "url": "http://192.168.31.4:35182",
            "description": "Office PC"
        }
    }
}

See Multi-Computer Setup Guide for details.
