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.

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 | $0.00040 | $0.00810 |
| Opus 5 | $0.00020 | $0.00405 |
| Sonnet 5 | $0.00008 | $0.00162 |
| Haiku 4.5 | $0.00004 | $0.00081 |
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 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.

Context
This plugin bundles the Windows MCP Server for Windows-only desktop automation. The server is strongest when you let Windows expose semantic UI information instead of guessing from screenshots.
Preferred workflow
- Use
window_managementto find or activate the target window. - Use
ui_find,ui_read,ui_click, andui_typefor normal controls. - Use
ui_read_tableto extract a grid, table, or details-view list into structured rows + headers in one call instead of scraping cells with repeatedui_read. - Use
file_savefor Save / Save As flows andfile_openfor Open flows instead of sending raw keyboard shortcuts. - Use
clipboard(get/set/clear) for fast bulk text IO — pair it with copy/paste hotkeys. - Use
ui_batchto run a multi-step sequence in one call, andui_macroto save that sequence by name and replay it later. - Only fall back to
screenshot_control,mouse_control, orkeyboard_controlwhen the UI Automation tree is missing or the target is a custom canvas.
Patterns
Semantic-first automation
- Prefer element names, control types, automation IDs, and window handles over screen coordinates.
- Re-check the UI tree after dialogs, page changes, or tab switches.
- Treat screenshots as discovery or fallback tools, not the primary control surface.
Screenshot fallback
- Use
screenshot_controlwhen the app is a game, canvas, OpenGL surface, or other custom-drawn UI. - If you need coordinates, get them from the annotated screenshot output first.
- Expect coordinate-based automation to be more fragile across DPI, layout, and monitor changes.
Multi-monitor and DPI
- Use monitor-aware tools instead of assuming the primary display.
- Negative coordinates are normal on virtual desktops with monitors positioned left or above the primary display.
- Keep work window-relative when possible to avoid DPI and layout drift.
Browsers and signed-in sessions
- Treat Edge and Chrome page content like any other semantic UI surface: start with
window_management, then useui_find,ui_click,ui_type, andui_readagainst visible text or ARIA labels. - To read the readable content of a web page, call
ui_readwithformat: "article": it returns the main article text only (navigation chrome, breadcrumbs, and "in this article" rails removed, inline link URLs stripped, headings/lists as markdown) — far more token-efficient than the raw document dump. Reading the live signed-in window this way also works for authenticated/internal pages an HTTP fetch cannot reach. - For authenticated or SSO-only sites, reuse an existing signed-in browser window/session first before launching the URL again.
- Do not interpret a Chromium launcher helper exiting immediately as a failed launch until you check whether the existing browser session already opened or focused the target page.
- Keep browser chrome (address bar, tabs, profile menus, extension flyouts) as best-effort; page content is the strong path.
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-automation is a skill published in the GitHub repository sbroenne/mcp-windows (91 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 810 once invoked, about $0.0002 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.
