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 | $0.00948 | $0.00948 |
| Opus 5.5 | $0.00379 | $0.00379 |
| Sonnet 5.5 | $0.00190 | $0.00190 |
| Haiku 4.5 | $0.00095 | $0.00095 |
Grade A, and why
mcp-server-trello 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Invariantes / regras criticas
- Credenciais (
TRELLO_API_KEY,TRELLO_TOKEN) so via env,.env, ou macOS Keychain -- nunca hardcoded, nunca comitadas. Ver.env.examplepara os nomes corretos. SKIP_PREPARE=truee obrigatorio nonpm installde dev para evitar build automatico dopreparehook.build/e gerado portsc+terser-- nao editar arquivos embuild/diretamente; a fonte e sempresrc/.- Rate limiter (
rate-limiter.ts) nao pode ser bypassado: a API Trello limita 300 req/10s por key e 100 req/10s por token; ultrapassar resulta em banimento temporario. - O binario
trello(CLI) e o servidor MCP (mcp-server-trello) compartilhamtrello-client.ts-- mudancas ali afetam ambas as superficies. - Toda nova ferramenta MCP deve ser registrada em
mcp-tools.tscom schema Zod completo e aparecer nos testes de paridade (parity.test.ts). ruvector.db(SQLite de embeddings) e gerado em runtime -- nao commitar.
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.
