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

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

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"
        }
    }
}

Cursor

Open Settings → MCP
Click Add new MCP server
Fill in:
- Name: winbridgeagent
- Type: http
- URL: http://<windows-ip>:35182

Or edit .cursor/mcp.json in your project root:

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

Windsurf

Edit ~/.codeium/windsurf/mcp_config.json:

{
    "mcpServers": {
        "winbridgeagent": {
            "serverUrl": "http://<windows-ip>:35182"
        }
    }
}

OpenClaw

Open Settings → MCP Servers
Click Add
Set:
- Name: winbridgeagent
- Transport: HTTP
- URL: http://<windows-ip>:35182

Cherry Studio

Open Settings → MCP Servers
Click Add Server
Select Streamable HTTP type
Set URL to http://<windows-ip>:35182

Cline (VS Code)

Edit cline_mcp_settings.json in your VS Code settings:

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

Generic MCP Client

Any MCP client that supports HTTP transport can connect using:

Server URL: http://<windows-ip>:35182
Transport: HTTP (Streamable HTTP)
Protocol Version: 2024-11-05

HTTP API

The server listens on the configured port (default 35182).

Open-source edition: No Bearer Token authentication required. All API endpoints are directly accessible.

If you have multiple computers with WinBridgeAgent installed on your LAN, configure your MCP client to manage them:

```json
{
    "mcpServers": {
        "winbridge-test": {
            "url": "http://192.168.31.3:35182",
            "description": "Test PC"
        },
        "winbridge-office": {
            "url": "http://192.168.31.4:35182",
            "description": "Office PC"
        }
    }
}

See Multi-Computer Setup Guide for details.

Configuration

A config.json file is auto-generated on first run:

    "auto_port": true,
    "listen_address": "0.0.0.0",
    "language": "en",
    "auto_startup": false,
