Critic-MCP AGENTS.md

Project instructions for Critic-MCP, an MCP server that acts as a second reviewer for code written by other AI coding assistants. It exposes one read-only review tool and covers its Node.js, TypeScript, model, configuration, and testing rules.

In plain words
What is it for?
Use it when developing or maintaining Critic-MCP and its `review_code` tool.
Why use it?
It keeps code review focused on inspection, with no permission to write files, while defining how inputs, model access, errors, and large code samples should be handled.

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.

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

Critic-MCP AGENTS.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 2d 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.

Critic-MCP — Proje Anayasası

Amaç

Diğer AI kodlama asistanlarının (Cursor, OpenCode vb.) yazdığı kodu salt okunur olarak denetleyen, "İkinci Göz / Eleştirmen" rolünde açık kaynak bir MCP sunucusu. Tek tool: review_code. Kesinlikle dosyaya yazma yetkisi yoktur.

Teknoloji Yığını

  • Node.js >= 20 (ESM, "type": "module") ve TypeScript (NodeNext çözünürlük)
  • @modelcontextprotocol/sdk — tek tool: review_code (stdio transport)
  • zod — girdi şema doğrulaması (sonraki aşamada handler'a eklenecek)
  • LLM: @google/genai (Gemini) veya openai paketleri (OpenAI / DeepSeek uyumlu)
  • Yetkilendirme: critic-mcp auth CLI akışı → ~/.critic-mcp.json (0600); env anahtarları dosyaya önceliklidir, asla hardcode değil

Klasör Yapısı

src/index.ts   -> MCP sunucu (tools/list + tools/call), zod doğrulama, hata yönetimi, `auth` argv yönlendirmesi
src/schema.ts  -> review_code zod girdi şeması (tek geçerli kaynak)
src/prompt.ts  -> Kritic sistem promptu ve kullanıcı promptu birleştirici
src/llm.ts     -> LLM istemci katmanı (gemini | openai | deepseek), zaman aşımı koruması
src/chunker.ts -> Satır-sonu bazlı kod parçalama (chunking) — varsayılan sınır 30.000 karakter
src/config.ts  -> Global yapılandırma (~/.critic-mcp.json) + kimlik çözümleme (env → dosya)
src/cli.ts     -> İnteraktif yetkilendirme akışı (`critic-mcp auth`)
tests/         -> Vitest birim testleri (validation.test.ts, llm.test.ts, chunking.test.ts, config.test.ts, cli.test.ts)
dist/          -> Derleme çıktısı (git'e girmiyor)
examples/      -> Manuel test: bad_code.js (SQLi+XSS+N+1) ve intent.txt
.env.example   -> Çevresel değişken şablonu (tümü isteğe bağlı)

Standartlar

  • Değişken/fonksiyon/dosya adları İngilizce; açıklama ve yorumlar Türkçe.
  • Yalnızca istenen işlevi yaz (YAGNI); gereksiz soyutlamadan kaçın.
  • Read-only prensibi: Sunucu hiçbir dosyaya yazamaz, sadece string rapor döner. Tek istisna: auth komutunun ~/.critic-mcp.json'a yazması (0600 izni, MCP sunucusu başlatılmadan).
  • LLM çıktısı standart metin olarak MCP istemcisine geri döner.
  • Her derleme/değişiklik öncesi npm run typecheck çalıştırılmalıdır.

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.
