SnoopWPF.Agent

An MCP (Model Context Protocol) server for WPF applications. Enables AI agents (Claude Code, Claude Desktop) to inspect the visual tree, read properties, diagnose binding errors, and capture screenshots of your running WPF app.

Requires .NET 8.0+. For older targets, use the injection-mode snoop-mcp.exe.

Quick Start

1. Add the package

<PackageReference Include="SnoopWPF.Agent" />

2. Start the agent

// App.xaml.cs
using SnoopWPF.Agent.Server;

protected override void OnStartup(StartupEventArgs e)
{
    base.OnStartup(e);
    SnoopAgent.StartCoLocated(); // stdio transport by default
}

3. Configure your MCP client

{
  "mcpServers": {
    "snoop": {
      "command": "dotnet",
      "args": ["run", "--project", "MyApp/MyApp.csproj"]
    }
  }
}

Options

SnoopAgent.StartCoLocated(new SnoopAgentOptions
{
    Transport      = TransportMode.Stdio,  // or TransportMode.Pipe
    EnableMutation = false,                // set true to allow wpf_set_property
    EnableRedaction = true,                // redact sensitive properties
    TimeoutMs      = 5000,                // per-operation Dispatcher timeout
});
