[![Database](https://img.shields.io/badge/database-pre--built-green)](https://github.com/Ansvar-Systems/argentine-law-mcp)

Query **Argentine federal legislation** — from Ley 25.326 (protección de datos personales) and the Código Penal to the Código Civil y Comercial, leyes de ciberseguridad, defensa del consumidor, and more — directly from Claude, Cursor, or any MCP-compatible client.

If you're building legal tech, compliance tools, or doing Argentine legal research, this is your verified reference database.

Built by [Ansvar Systems](https://ansvar.eu) -- Stockholm, Sweden

---

## Why This Exists

Argentine legal research is scattered across InfoLEG, SAIJ, the Boletín Oficial, and individual ministerial sites. Whether you're:
- A **lawyer** validating citations in a brief or contract
- A **compliance officer** checking obligations under Ley 25.326 or Ley 27.078
- A **legal tech developer** building tools on Argentine law
- A **researcher** tracing the legislative history of a ley nacional

...you shouldn't need a dozen browser tabs and manual PDF cross-referencing. Ask Claude. Get the exact provision. With context.

This MCP server makes Argentine law **searchable, cross-referenceable, and AI-readable**.

> **Initial release:** The Argentine law database is actively being populated from InfoLEG (servicios.infoleg.gob.ar) and SAIJ (saij.gob.ar). Coverage will expand with each release. See the roadmap below.
