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 | $0.03437 | $0.03437 |
| Opus 5 | $0.01718 | $0.01718 |
| Sonnet 5 | $0.00687 | $0.00687 |
| Haiku 4.5 | $0.00344 | $0.00344 |
Grade A, and why
mcp-firefly-iii 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 10d 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 — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Firefly III MCP Sunucusu
Kişisel bir Firefly III örneğini yapay zekâ asistanlarına açan bir MCP sunucusu. Tek bir canlı örnek için geliştiriliyor; bu yüzden burada genellik değil, gerçek finansal veri üzerinde doğruluk önemli.
Proje dili Türkçe: dokümantasyon ve bu dosya Türkçe yazılır. Kod içi docstring ve yorumlar İngilizce kalır.
Komutlar
make test # tüm testler, mock'lu, ağa çıkmaz (~3sn)
make check # canlı örneğe karşı salt-okunur sağlık kontrolü
make run # sunucuyu stdio üzerinden çalıştır
make coverage # kapsam raporu (kapı yok, isteğe bağlı)
make inspector # tarayıcıda interaktif araç gezgini
Her şey Node.js/npm üzerinden çalışır. Testler .env.test, run, check ve
parity ise .env dosyasını okur.
Mimari
src/
entities/ entity operations and Firefly request mapping
schemas/ hand-written strict Zod input schemas
registry operation registration, validation, read-only gate, projection
firefly HTTP client and Firefly error translation
Operasyonlar defineOperation ile tanımlanır ve meta-araçlar üzerinden sunulur
— çoğu MCP istemcisi ~40 aracın üzerinde bozulduğu için. Çalıştırma riske göre
üçe bölünmüştür (firefly_query, firefly_mutate, firefly_destructive),
yanına firefly_list_operations ve firefly_get_schema gelir. Bölme
Registry.execute içinde uygulanır: yanlış yüzeyden çağrılan bir operasyon
WrongAccessSurfaceError ile reddedilir, yoksa tool annotation'ı sunucunun
tutmadığı bir iddia olurdu.
Operasyon ekleme
src/schemas/— strict input schemasrc/entities/<varlık>.ts—defineOperationile operation ve HTTP mappingsrc/server.ts— yeni module kaydıtest/— mocked request/response and validation tests
İki şeyi atlamak kolay:
Her operasyonu read, write veya destructive diye etiketleyin.
Üç çalıştırma yüzeyi ve OAuth kapsamları bu etiketlere bakar.
destructive, çağıranın geri alamayacağı alt kümedir: kaydı siler, ya da tek
çağrıda çok kaydın bir alanını yeniden yazar. Kapı tek bir yerde, permits ile
seviye karşılaştırarak çalışır — etiketi tamamen unutulmuş bir operasyonu
yakalayacak ikinci bir isim listesi yok, ama access zorunlu alan olduğu için
eksik etiket derleme hatası olur.
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.
