windows-automation

windows-automation is a skill for Claude Code, Codex from sbroenne/mcp-windows. It costs 37 tokens per session (1,244 once invoked), scanned A, original, MIT.

Guidance for automating Windows desktop applications through the Windows MCP server, which gives an agent structured access to windows and interface controls. It covers normal controls, files, tables, screenshots, keyboards, mice, and display scaling.

In plain words
What is it for?
Use it to find windows, read or click controls, enter text, open and save files, copy clipboard data, work with tables, replay action sequences, and handle DPI or multi-monitor issues.
Why use it?
It helps automation target named interface elements instead of guessing screen positions. It also explains when screenshots or mouse and keyboard control are needed for custom interfaces.

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-automation 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

Use this skill with a configured Windows MCP Server in any compatible host. Let Windows expose control names, state, and IDs instead of guessing from screenshots. The skill itself does not install or configure the server.

Preferred workflow

  1. Use window_management to find or activate the target window.
  2. Discover with ui_find or ui_snapshot; pass the returned IDs to ui_read, ui_click, and ui_type.
  3. Use ui_read_table to extract a grid, table, or details-view list into structured rows + headers in one call instead of scraping cells with repeated ui_read.
  4. Use file_save for supported Save / Save As dialogs and file_open for Open flows. After failure or confirmation_required, inspect the existing dialog and choose the next action explicitly. These helpers do not approve overwrites, dismiss errors, or retry dispatched actions.
  5. Use clipboard (get/set/clear) for fast bulk text IO — pair it with copy/paste hotkeys.
  6. Use ui_batch to run a multi-step sequence in one call. Keep reusable steps in project files.
  7. Only fall back to screenshot_control, mouse_control, or keyboard_control when the UI Automation tree is missing or the target is a custom canvas.

Patterns

Semantic-first automation

  • Discover using names, control types, and automation IDs; act using the returned opaque elementId.
  • Click, double-click, type, select, table reads, and state waits require IDs. Selection values still identify option text, while the ID identifies the containing control.
  • Selectors are only for discovery and appear/disappear waits. Removed action selectors are errors.
  • Read an element with its ID; omit the ID only for an explicit whole-window read. Element reads never widen to window OCR.
  • Stale IDs require rediscovery. IDs belong to one owner and never transfer between MCP instances or the CLI daemon.
  • Batch $prev requires one unambiguous immediately preceding result. Reusable batches should discover fresh controls on every run.
  • Each batch step requires its matching enabled tool (key: keyboard_control; mouse/polyline: mouse_control). Forbidden steps reject the whole batch before it starts, even with stopOnError=false. withSnapshot=true requires enabled ui_snapshot before any action. Never route around disabled tools.
  • Re-check the UI tree after dialogs, page changes, or tab switches.
  • Treat screenshots as discovery or fallback tools, not the primary control surface.
