Armadilhas

Treating output as legal advice — This is a triage tool. Anything material goes to licensed counsel.

Picking a winner on every clause without context — Ask Claude to call 'similar' explicitly when the diff is immaterial

Ferramentas

O que este MCP expõe

Ferramenta	Entradas	Quando chamar	Custo
Clause classification	contract_path: str	First pass on any contract	Claude tokens (high for long contracts)
Risk flagging	classified contract, jurisdiction?	After classification	Claude tokens
Redline generation	flags	When you intend to push back	Claude tokens
Comparison	contracts: list	Multi-vendor evals	Claude tokens
Counsel brief	flags	Before handing off to counsel	Claude tokens

Custo e limites

O que custa rodar

Cota de API: None
Tokens por chamada: 20-100k tokens per contract (long docs are expensive)
Monetário: Free (consumes Claude subscription)
Dica: Chunk long contracts by section; don't re-analyze unchanged sections on each pass.

Segurança

Permissões, segredos, alcance

Armazenamento de credenciais: No credentials. Contracts stay local except for Claude inference.

Saída de dados: Contract text is sent to Anthropic for inference. Confidential contracts should use a workspace with data retention disabled.

Not a substitute for licensed legal counsel. Do not sign anything material based solely on this output.
CUAD benchmarks are US-skewed. Non-US jurisdictions need explicit framing.

Solução de problemas

Erros comuns e correções

PDF text extraction garbled

Convert to markdown first with a tool like marker or pandoc; image-based PDFs need OCR.

Redlines touch boilerplate the other side will reject

Ask skill to distinguish 'must-have' from 'nice-to-have' and drop the latter
