CLAUDE.md

windows-computer-use-mcp CLAUDE.md is an instructions file for Claude Code from betrayzl/windows-computer-use-mcp. It costs 718 tokens per session, scanned A, original, MIT.

Project instructions for a Windows automation server that lets an agent control a computer through the Model Context Protocol, a standard way for AI tools to connect to software.

In plain words
What is it for?
Use them when developing, compiling, or maintaining the Windows computer-use server.
Why use it?
They explain how to build and work on the project, including its Rust, TypeScript, and bundling steps.

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.

Security

Grade A, and why

windows-computer-use-mcp 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 9d 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.

Build Commands

The project uses a custom build process that involves compiling a Rust native module, compiling TypeScript, and bundling the output into a single executable package.

  • Full Build: node build.js
    • This runs the complete pipeline:
      1. Compile Rust native module: Runs napi build --platform --release in the native/ directory.
      2. Compile TypeScript: Runs npx tsc to generate JavaScript from TypeScript sources.
      3. Bundling: Uses @vercel/ncc to bundle the code in dist/index.js into the bundle/ directory.
      4. Finalize: Copies the compiled .node module into the bundle/ folder and renames it to win-cu-native.node.
  • TypeScript Compilation Only: npx tsc
  • Native Module Build Only: cd native && napi build --platform --release

Project Structure

This is a Model Context Protocol (MCP) server providing Windows automation capabilities.

  • src/: TypeScript source code.
    • index.ts: MCP server entry point; defines the server and all available tools.
    • executor.ts: Implementation of the ComputerExecutor interface; orchestrates calls to the native module.
    • native-loader.ts: Handles the logic for finding and loading the compiled .node binary.
    • types.ts: Core TypeScript interface definitions (e.g., ComputerExecutor, DisplayGeometry).
    • utils.ts: Helper functions for coordinate conversion (logical to physical) and DPI scaling.
    • Feature toggles and cross-instance mutual exclusion are planned but not yet implemented.
  • native/: Rust source code using napi-rs for high-performance Windows API interaction.
    • Provides core capabilities: Mouse/Keyboard simulation (enigo), Screen capture (dxgi), Window management (windows crate), and Clipboard access (arboard).
  • dist/: Compiled TypeScript output (gitignored).
  • bundle/: Production-ready output (gitignored) containing index.js and the .node module.
  • tests/: Test scripts and regression drivers.

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.
