What is WPFVisualTreeMcp CLAUDE.md?

A project instruction file for WPFVisualTreeMcp, a .NET tool that lets an AI agent inspect the visible control hierarchy of running Windows desktop applications.

Use it when building, testing, publishing, or running the WPFVisualTreeMcp server and its sample desktop application.

It gives contributors the project commands, architecture, and test steps needed to build and verify the tool.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.05111	$0.05111
Opus 5.5	$0.02044	$0.02044

Security

Grade A, and why

WPFVisualTreeMcp CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Project Overview

WpfVisualTreeMcp is an MCP (Model Context Protocol) server that enables AI agents to inspect running WPF applications in real-time. It exposes WPF visual tree inspection capabilities similar to Snoop WPF or Visual Studio's Live Visual Tree through the MCP protocol.

Build Commands

# Build solution
dotnet build WpfVisualTreeMcp.sln

# Build for Release
dotnet build -c Release WpfVisualTreeMcp.sln

# Run tests
dotnet test WpfVisualTreeMcp.sln

# Run sample WPF app for testing
dotnet run --project samples/SampleWpfApp

# Publish MCP Server executable (same exe also runs as the CLI)
dotnet publish src/WpfVisualTreeMcp.Server/WpfVisualTreeMcp.Server.csproj -c Release -o ./publish

# Run as CLI (any subcommand switches from MCP server mode to CLI mode)
dotnet run --project src/WpfVisualTreeMcp.Server -- list
./publish/WpfVisualTreeMcp.Server.exe help

# Package the C# SDK and test the installed package against fresh WPF apps
dotnet pack src/WpfVisualTreeMcp.Automation -c Release -o artifacts/packages
python scripts/test_automation_package.py --packages artifacts/packages
# Add --gestures on an unlocked desktop to exercise real drag/touch and replay

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
