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 | $0.01067 | $0.01067 |
| Opus 5.5 | $0.00427 | $0.00427 |
| Sonnet 5.5 | $0.00213 | $0.00213 |
| Haiku 4.5 | $0.00107 | $0.00107 |
Grade A, and why
Unofficial-VS-MCP CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
プロジェクトメモ
StdioProxy デプロイに関する注意
VsMcpPackage.DeployStdioProxy() はソースとターゲットの FileVersion を比較し、同じならコピーをスキップする。
開発中はアセンブリバージョンを変えずにコード修正することが多いため、ビルド後に手動コピーが必要：
Copy-Item 'src\VsMcp.StdioProxy\bin\Debug\net8.0\VsMcp.StdioProxy.dll',
'src\VsMcp.StdioProxy\bin\Debug\net8.0\VsMcp.StdioProxy.exe',
'src\VsMcp.StdioProxy\bin\Debug\net8.0\VsMcp.StdioProxy.deps.json',
'src\VsMcp.StdioProxy\bin\Debug\net8.0\VsMcp.StdioProxy.runtimeconfig.json',
'src\VsMcp.StdioProxy\bin\Debug\net8.0\VsMcp.Shared.dll',
'src\VsMcp.StdioProxy\bin\Debug\net8.0\Newtonsoft.Json.dll' `
-Destination "$env:LOCALAPPDATA\VsMcp\bin\" -Force
StdioProxy オフライン応答アーキテクチャ
VS未起動でも StdioProxy が即終了せず、ローカル応答を返す仕組み：
VS起動時: Claude Code → StdioProxy → VS Extension HTTP → 全リクエスト中継
VS未起動時: Claude Code → StdioProxy → ローカル応答(initialize/tools/list/ping)
→ tools/call は "VS未起動" エラー

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.
- 2mo ago First seen · 63 lines · 1,067 tokens per session scan A 8aba0d391e0f
Unofficial-VS-MCP CLAUDE.md is an instructions file published in the GitHub repository dhq-boiler/Unofficial-VS-MCP (20 stars, last pushed 8d ago), licensed MIT. It adds 1,067 tokens to every session, about $0.0043 per session on Opus 5.5. 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.
