Windows-MCP is an MCP server that lets AI agents operate Windows computers through actions such as navigating files, opening applications, controlling windows, and interacting with user interfaces. It is used for desktop automation, software testing, and other tasks that require an agent to use Windows.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01930 | $0.01930 |
| Opus 5 | $0.00965 | $0.00965 |
| Sonnet 5 | $0.00386 | $0.00386 |
| Haiku 4.5 | $0.00193 | $0.00193 |
Grade A, and why
Windows-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 6d 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
Windows-MCP is a Python MCP (Model Context Protocol) server that bridges AI LLM agents with the Windows OS, enabling direct desktop automation. It exposes 20 tools via FastMCP:
| Group | Tools |
|---|---|
| Capture | Screenshot, Snapshot, Scrape, DisplayInventory |
| Input | Click, Type, Scroll, Move (also drag-and-drop via drag=True), Shortcut, MultiSelect, MultiEdit |
| Timing | Wait, WaitFor |
| System | App, PowerShell, FileSystem, Registry, Process, Clipboard, Notification |
Tool names are defined by the name= argument of each @mcp.tool(...) in src/windows_mcp/tools/; that directory is the source of truth. Note the shell tool is registered as PowerShell, not Shell. Any subset can be removed at startup with --disable-tools (e.g. --disable-tools PowerShell,Registry).
Build & Development Commands
uv sync # Install dependencies
uv run windows-mcp # Run the MCP server
ruff format . # Format code
ruff check . # Lint code
ruff check --fix . # Lint and auto-fix
pytest # Run all tests
pytest tests/test_foo.py # Run a single test file
Package manager: UV (not pip). Python: 3.13+. Build backend: Hatchling.
Architecture
The codebase follows a layered service architecture under src/windows_mcp/:
Entry point — __main__.py: Builds the FastMCP server, parses CLI flags, and selects the transport. Tool registration is delegated to tools.register_all(); an async lifespan initializes the Desktop, WatchDog, and Analytics singletons, which tools resolve lazily through the get_desktop / get_analytics callables.
Tools layer — tools/: One module per tool group, each exposing register(mcp, *, get_desktop, get_analytics). tools/__init__.py holds the module list and register_all(). Tool functions are thin — they normalize arguments and delegate to a service package. The @with_analytics decorator wraps each one for telemetry, making it the existing precedent for cross-cutting concerns at the tool boundary.
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.

Windows-MCP CLAUDE.md is an instructions file published in the GitHub repository CursorTouch/Windows-MCP (6,910 stars, last pushed yesterday), licensed MIT. It adds 1,930 tokens to every session, about $0.0097 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
