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 | $0.01703 | $0.01703 |
| Opus 5.5 | $0.00681 | $0.00681 |
| Sonnet 5.5 | $0.00341 | $0.00341 |
| Haiku 4.5 | $0.00170 | $0.00170 |
Grade A, and why
mcp-windows copilot-instructions.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 28d 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 — 130 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copilot Instructions for mcp-windows
Language and documentation
- Use simple, jargon-free English in replies, README files, website pages, and other documentation written for users.
- Write for someone who is new to the project. Explain what it does, how to install it, and how to complete a first useful task before giving technical details.
- Use everyday words and short, direct sentences. Explain any necessary technical term when it first appears. Keep exact command names and options unchanged.
- Describe the current product, not its development history or rejected experiments. Keep release history in the changelog, not in getting-started guides.
- Put detailed settings, test methods, and implementation details in the relevant reference pages rather than the README introduction.
- Say "MCP or the command line (CLI)" in introductory copy. Explain
winclias the program's name only where installation steps or exact commands need it. - Keep the website's user guides separate from developer manuals, agent instruction files, and release history. Do not paste those references into beginner pages.
Code Review

Sister Projects
mcp-windows is one of a family of Windows-only MCP-server repos maintained by the same author
(sbroenne). The family also includes:
mcp-server-excel(sbroenne/mcp-server-excel) — Excel COM automation. This is the authoritative architectural template for the family's general server-side patterns: layered architecture (Core → Service → CLI/MCP Server), the "two equal entry points" (MCP Server + CLI) principle, Unified Service Architecture (shared daemon/session registry), and its support/audit scripts (scripts/*.ps1) and CI Gate workflow.mcp-windowsis UI-automation-focused (FlaUI/ pywinauto patterns) rather than COM/Office-interop-focused, so not every Excel pattern applies directly — but when solving a cross-cutting problem (session lifecycle, CLI/MCP parity, daemon process management, pre-commit audit tooling), check how Excel solved it first.mcp-server-powerpoint(sbroenne/mcp-server-powerpoint) — PowerPoint COM automation, structurally mirrorsmcp-server-excel.
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.
