Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: mentions CLAUDE.md.

This is lab-dados/juscraper-mcp's own configuration. It tells Claude Code how to work on juscraper-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything juscraper-mcp configures →

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

juscraper-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 7d 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 — 51 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CLAUDE.md

Servidor MCP público do juscraper (consultas a tribunais brasileiros sem autenticação), deployado em Azure Container Apps. Segue os padrões do repo irmão ../escritorio-servicos (ver o CLAUDE.md de lá). O pacote consumido é ../juscraper (instalado via git+https no build).

Comandos

Python é gerido exclusivamente por uv. Nunca pip install. O uv.lock não é commitado (resolvido no build da imagem).

uv sync
uv run uvicorn main:app --reload --port 8080
uv run pytest
uv run ruff check . && uv run ruff format .
uv run python scripts/smoke_client.py [url] [--real]

Estrutura

  • main.py — entrypoint ASGI (main:app).
  • juscraper_mcp/server.py — FastMCP (stateless + json_response, obrigatório para scale-to-zero), instructions, /health.
  • juscraper_mcp/tools.py — tools MCP. Regras invioláveis:
    • toda chamada ao juscraper passa por _executar (semáforo + thread + timeout);
    • filtros None não são repassados (os schemas do juscraper têm extra="forbid");
    • erros viram ToolError com mensagem em português que oriente o modelo a corrigir.
  • juscraper_mcp/registry.py — catálogo de tribunais. Para adicionar um tribunal novo, adicione a entrada aqui (e nada mais, se o juscraper já o suporta via jus.scraper(sigla)). Critério de entrada: funciona sem autenticação e sem captcha (TJMG e JusBR ficam fora).
  • juscraper_mcp/serialize.py — DataFrame → JSON truncado (limites em settings.py).
  • infra/ — Terraform que reusa o RG/CAE/ACR do escritorio-servicos. Não criar recursos de custo fixo. Orçamento do projeto: R$ 200/mês (budget alert já configurado); max_replicas=20 existe para uso em sala de aula, mas min_replicas=0 e 0.25 vCPU são decisões de custo — não aumentar sem discutir.

Testes

Os testes não acessam tribunais: tests/test_tools.py usa sessão MCP em memória (mcp.shared.memory) com _get_scraper monkeypatchado. Ao corrigir um bug, adicione um teste que falhe no código antigo. Verificação real contra tribunais: só via scripts/smoke_client.py --real, manualmente.

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.
