A MCP server for agent-based research on Brazilian law

Brazilian Law Research MCP Server

🇧🇷 Leia em português

A MCP (Model Context Protocol) server for agent-driven research on Brazilian law using official sources.

Foreword

This server empowers models with scraping capacities, thus making research easier to anyone legitimately interested in Brazilian legal matters.

This facility comes with a price: the risk of overloading the official sources' servers if misused. Please be sure to keep the load on the sources to a reasonable amount.

Development

Tooling

The project uses:

• Ruff for linting and formatting.
• BasedPyright for type checking.
• Pytest for testing.

Language

Resources, tools and prompts related stuff must be written in Portuguese, because this project aims to be used by non-dev folks, such as lawyers and law students.

Technical legal vocabulary is highly dependent on a country's legal tradition and translating it is no trivial task.

Development related stuff should stick to English as conventional, such as source code.
