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 | $0.01296 | $0.01296 |
| Opus 5 | $0.00648 | $0.00648 |
| Sonnet 5 | $0.00259 | $0.00259 |
| Haiku 4.5 | $0.00130 | $0.00130 |
Grade A, and why
MCP_for_Windows 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 8d 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 16 tools (App, Shell, Screenshot, Snapshot, Click, Type, Scroll, Move, Shortcut, Wait, Scrape, MultiSelect, MultiEdit, Clipboard, Process, Notification) via FastMCP.
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 (if tests/ exists)
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: Registers all 15 MCP tools on a FastMCP server instance. Uses an async lifespan to initialize Desktop, WatchDog, and Analytics services. Each tool function delegates to Desktop methods. The @with_analytics decorator wraps tools for telemetry.
Desktop service — desktop/service.py: High-level orchestrator. Manages window operations (launch, resize, switch), screenshots, mouse/keyboard actions, and clipboard. Interfaces with Tree service for UI element discovery. desktop/views.py defines data models: DesktopState, Window, Size, BoundingBox, Status.
Tree service — tree/service.py: Captures the Windows accessibility tree from active and background windows. Identifies interactive elements and scrollable areas. Uses ThreadPoolExecutor for multi-threaded UI traversal. tree/views.py defines TreeElementNode, ScrollElementNode, TreeState. tree/config.py has control type configurations.
UIAutomation wrapper — uia/: Low-level abstraction over the Windows UIAutomation COM API via comtypes. core.py wraps the main automation object, controls.py has control-specific logic, patterns.py wraps UIAutomation patterns, enums.py has COM enumerations, events.py handles event subscriptions.
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.
