Dominican Law MCP Server

Dominican Republic Law MCP Server

The Senado de la República Dominicana alternative for the AI age.

Query Dominican Republic statutes -- from Ley 172-13 on data protection and the Código Penal to the Código de Trabajo and Código Civil -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Dominican legal research is scattered across senado.gob.do, camaradediputados.gob.do, and consultoria.gov.do. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking whether a statute is still in force
• A legal tech developer building tools on Dominican law
• A researcher tracing legislative developments across the Congreso Nacional

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

This MCP server makes Dominican Republic law searchable, cross-referenceable, and AI-readable.

Example Queries

Once connected, just ask naturally (in Spanish or English):

• "¿Qué dice la Ley 172-13 sobre protección de datos personales respecto al consentimiento?"
• "Buscar disposiciones sobre protección de datos personales en la legislación dominicana"
• "¿Está vigente el Código Penal Dominicano?"
• "Buscar artículos sobre contrato de trabajo en el Código de Trabajo"
• "¿Qué establece el Código Civil sobre obligaciones?"
• "Buscar legislación sobre sociedades comerciales en República Dominicana"
• "Validar la cita Ley 479-08 sobre Sociedades Comerciales"
• "What does the Personal Data Protection Law (172-13) say about data subject rights?"

What's Included

Note: This server is in active ingestion. The database infrastructure is deployed and operational. Statute content is being populated from authoritative Dominican sources. Use list_sources to see current coverage, and about for the latest statistics.

Verified data only -- every citation is validated against official sources (consultoria.gov.do, Senado, Cámara de Diputados). Zero LLM-generated content.

---

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from official Dominican government sources (consultoria.gov.do, senado.gob.do, camaradediputados.gob.do)
• Provisions are returned unchanged from SQLite FTS5 database rows
• Zero LLM summarization or paraphrasing -- the database contains statute text, not AI interpretations

Smart Context Management:

• Search returns ranked provisions with BM25 scoring (safe for context)
• Provision retrieval gives exact text by statute identifier + article number
• Cross-references help navigate without loading everything at once

Technical Architecture:

consultoria.gov.do / senado.gob.do --> Parse --> SQLite --> FTS5 snippet() --> MCP response
                                         ^                        ^
                                  Provision parser         Verbatim database query

Traditional Research vs. This MCP

Traditional: Search portal -> Navigate HTML -> Ctrl+F -> Cross-reference between statutes -> Repeat

This MCP: "¿Qué dice la Ley 172-13 sobre el derecho de acceso a los datos personales?" -> Done.

International Law Alignment

The Dominican Republic is not an EU member state. The international alignment tools cover the frameworks that matter for Dominican law practice:

• OAS frameworks -- Organization of American States conventions and model laws (including the OAS Model Law on Data Protection)
• CAFTA-DR -- Dominican Republic-Central America-United States Free Trade Agreement obligations
• CARICOM observer -- Caribbean Community frameworks and alignment
• Ley 172-13 aligns with international data protection principles; the get_eu_basis tool maps these to GDPR-equivalent provisions for cross-reference
• Código de Trabajo aligns with ILO conventions and CAFTA-DR labor chapters

The international bridge tools allow you to explore alignment relationships -- checking which Dominican provisions correspond to international requirements, and vice versa.

Note: International cross-references reflect alignment and treaty obligations, not transposition. The Dominican Republic adopts its own legislative approach, and these tools help identify where Dominican and international law address similar domains.

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Dominican government 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 before court filings
• International cross-references reflect alignment relationships, not formal transposition
• Database is in active ingestion -- use list_sources to verify current coverage before relying on a specific statute

Before using professionally, read: DISCLAIMER.md | SECURITY.md

Client Confidentiality

Queries go through the Claude API. For privileged or confidential matters, use on-premise deployment.
