Wpf Visual Tree MCP server

WpfVisualTreeMcp

<!-- mcp-name: io.github.faze79/wpf-visual-tree -->

Let AI agents see, debug and drive running WPF apps. Snoop + Playwright for AI, exposed over the Model Context Protocol — visual tree, data bindings, screenshots, clicks, text input and keyboard, against any running WPF process, no source changes needed.

An AI agent queries controls by visible text, fills the form, selects a list item, clicks Submit — then explains why the Status box stayed empty by pulling the app's binding errors. Every step is one MCP tool call (or CLI command).

Quickstart (60 seconds)

1. Download and extract the latest release zip (requires the .NET 8 Desktop Runtime).
2. Register it in your MCP client — for Claude Code, add to .mcp.json:

{
     "mcpServers": {
       "wpf-visual-tree": {
         "command": "C:/path/to/WpfVisualTreeMcp.Server.exe",
         "args": []
       }
     }
   }

1. Ask your agent: "Look at my running WPF app and tell me why the Save button is disabled."

Prefer the terminal? The same exe is a full CLI: WpfVisualTreeMcp.Server.exe help.

Overview

WpfVisualTreeMcp is a Model Context Protocol (MCP) server that allows AI coding agents (Claude Code, Cursor, GitHub Copilot) to inspect and interact with running WPF applications. Think of it as giving your AI assistant the same capabilities as tools like Snoop WPF or Visual Studio's Live Visual Tree.

Why This Matters

Debugging WPF UI issues traditionally requires manual inspection with specialized tools. This project bridges that gap by exposing WPF inspection capabilities through MCP, enabling AI agents to:

• Understand UI structure during code reviews
• Diagnose binding errors automatically
• Suggest fixes for layout issues
• Assist with UI refactoring tasks
• Analyze visual tree hierarchies in real-time

Features

Core Inspection

• Process Discovery - List all running WPF applications available for inspection
• Visual Tree Navigation - Traverse the complete visual tree hierarchy
• Logical Tree Access - Navigate the logical tree structure
• Property Inspection - Read all dependency properties of any UI element

Binding & Resources

• Binding Analysis - Inspect bindings with converter, StringFormat, FallbackValue, MultiBinding support
• DataContext Inspection - View DataContext type, properties, INPC status, and inheritance chain
• Binding Error Detection - Automatically capture and report binding errors with classification
• Resource Enumeration - Browse resource dictionaries at any scope
• Style Inspection - View applied styles and templates

Search & Monitoring

• Element Search - Find elements by type, name, or property values
• Deep Search - Search entire tree including AdornerLayer and Popup elements
• Property Watching - Monitor property changes in real-time
