## What it does

Jus MCP provides a single HTTP connection at `https://api.mcp.ai/jus` to query Brazilian legal databases. It finds lawsuits using court numbers, party names, or taxpayer identifiers (CPF and CNPJ). The tool retrieves DJEN gazette notices and TCU court rulings alongside tender specifications from the PNCP platform.

The server also includes sixteen legal calculation routines. It indexes overdue debts through benchmarks like IPCA and computes rental arrears. For background vetting, it issues clearance certificates like CNDT and flags matches across public sanction registries.

Getting started requires no credentials. Public queries run immediately, while premium calls draw from prepaid credits.
