| Category | Count | Details |
|---|---|---|
| Statutes | Ingestion in progress | Laws from SPIJ (spij.minjus.gob.pe) and El Peruano |
| Provisions | Ingestion in progress | Full-text searchable with FTS5 |
| Language | Spanish | Peru's official language |
| Daily Updates | Automated | Freshness checks against SPIJ |
Coverage note: The Peruvian law database is actively being built. The MCP server infrastructure is production-ready. Provision counts will be updated as ingestion completes. The remote endpoint is live and returns available data.
Verified data only -- every citation is validated against official sources (SPIJ / El Peruano). Zero LLM-generated content.

| Traditional Approach | This MCP Server |
|---|---|
| Buscar en SPIJ por número de ley | Buscar en español: "protección de datos consentimiento" |
| Navegar artículos manualmente | Obtener la disposición exacta con contexto |
| Referencias cruzadas manuales entre leyes | build_legal_stance agrega de múltiples fuentes |
| "¿Está esta ley vigente?" -- verificar manualmente | check_currency -- respuesta en segundos |
| Buscar marcos internacionales -- revisar textos de la CAN | get_eu_basis -- instrumentos internacionales vinculados |
| Sin API, sin integración | Protocolo MCP -- nativo para IA |
Tradicional: Buscar en SPIJ --> Descargar PDF --> Ctrl+F --> Verificar en El Peruano --> Repetir
This MCP: "¿Cuáles son los derechos de los titulares de datos bajo la Ley 29733?" --> Done.

Peru is a member of the Andean Community (CAN) and the OAS, with significant multilateral treaty obligations that shape domestic legislation.
| Framework | Relevance |
|---|---|
| Andean Community (CAN) | Peru participates in Andean legal harmonization -- Decisions of the Andean Commission are directly applicable |
| OAS Conventions | Peru has ratified inter-American conventions on corruption, human rights, and mutual legal assistance |
| OECD Accession | Peru is in OECD accession discussions -- governance, anti-corruption, and data protection modernization |
| USMCA/Trade Agreements | Peru has trade agreements with the US, EU, and others containing IP, digital trade, and data governance provisions |
Peru's data protection law (Ley 29733) aligns with APEC Privacy Framework principles and draws on international standards. The international bridge tools help identify where Peruvian law aligns with these frameworks.
Note: Peru is not an EU adequacy jurisdiction under GDPR. The international tools reflect alignment relationships, not binding mutual recognition. For cross-border data transfers from the EU to Peru, appropriate safeguards under GDPR Article 46 apply.

THIS TOOL IS NOT LEGAL ADVICE
Statute text is sourced from SPIJ (official Peruvian legal publications). However:
- This is a research tool, not a substitute for professional legal counsel
- Court case coverage is not included -- do not rely solely on this for case law research
- Verify critical citations against primary sources (SPIJ / El Peruano) for court filings
- International cross-references reflect alignment relationships, not binding obligations
- Andean Community Decisions are directly applicable in Peru -- verify CAN instruments separately
