Frequently asked questions
**Do you need a login or an account? No, not to start. Public sources answer the first question. Only paid queries require an account with a credit balance.
**Does it cost more than installing the MCPs separately? No. Each query costs exactly the same as it would in the standalone MCP — the bundle is discovery convenience, not extra markup.
What is free? Court cases and case updates (CNJ/DataJud), publications and court notices (DJEN), jurisprudence, CNPJ/CPF data, transparency, municipal gazettes, the 16 court calculations, PNCP bidding and TCU decisions.
**Does it retrieve cases under judicial secrecy? No. Only what is public in the official databases.
**Does it download the case documents/decisions? PUBLIC DECISIONS: yes — rulings and full records, downloaded from the court and already converted to text, with a temporary PDF link. The full court record, including motions, depends on an attorney credential on the court system, we don’t do that.
**Is the server open source? The server is proprietary (hosted). This repository is the public wrapper with manifests, docs, and skills, all MIT.
