Colombian Law MCP Server

The Secretaría del Senado alternative for the AI age.

Query Colombian legislation -- from Ley 1581 de protección de datos and the Código Penal to the Código Civil, Código de Comercio, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Colombian legal research means navigating secretariasenado.gov.co, funcionpublica.gov.co, and the Diario Oficial's sprawling archive. Whether you're:

• A lawyer validating citations before the Corte Suprema de Justicia or Corte Constitucional
• A compliance officer checking Ley 1581 (data protection) or SIC obligations
• A legal tech developer building tools on Colombian law
• A researcher tracing legislative history across Colombia's comprehensive code system

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

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

What's Included

Initial release: The statute database is currently being populated. Premium data is available now.

Category	Count	Details
Statutes	Initial release	Ingestion from secretariasenado.gov.co and funcionpublica.gov.co in progress
Provisions	Initial release	Full-text search will be available as corpus expands
Premium: Case Law	29,284 decisions	Corte Constitucional, Corte Suprema, Consejo de Estado (Premium tier)
Premium: Preparatory Works	119,424 documents	Gaceta del Congreso, exposiciones de motivos (Premium tier)
Premium: Agency Guidance	31,809 documents	SIC, SFC, ANE circulares and conceptos (Premium tier)
Database Size	Pre-built SQLite	Optimized, portable

Verified data only -- every citation is validated against official sources. Zero LLM-generated content.

The premium dataset is one of the richest in the fleet: 180,517 documents covering decisions from Colombia's three high courts plus 31,809 regulatory guidance documents from the SIC, SFC, and ANE. The free statute tier is under active ingestion.

---

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from secretariasenado.gov.co and funcionpublica.gov.co official sources
• 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 law number + article
• Cross-references help navigate without loading everything at once

Technical Architecture:

secretariasenado.gov.co / funcionpublica.gov.co --> Parse --> SQLite --> FTS5 snippet() --> MCP response
                                                     ^                        ^
                                              Provision parser         Verbatim database query

Traditional Research vs. This MCP

Traditional Approach	This MCP Server
Search secretariasenado.gov.co by ley number	Search by plain language: "protección datos personales"
Navigate multi-article codes manually	Get the exact provision with context
Manual cross-referencing between laws	build_legal_stance aggregates across sources
"¿Está vigente esta ley?" -- check manually	check_currency tool -- answer in seconds
Find international alignment -- dig through external sources	get_eu_basis -- linked frameworks instantly
No API, no integration	MCP protocol -- AI-native

Traditional: Buscar en secretariasenado.gov.co --> Navegar el código --> Ctrl+F --> Cruzar referencias --> Repetir

This MCP: "¿Qué obligaciones impone la Ley 1581 a los responsables del tratamiento de datos?" --> Done.

International Law Alignment

Colombia is not an EU member state, but several Colombian laws have significant international alignment:

• Ley 1581 de 2012 (Habeas Data / data protection) draws from GDPR principles and the APEC Privacy Framework. The SIC (Superintendencia de Industria y Comercio) has adopted adequacy-like frameworks for international data transfers
• Ley 527 de 1999 (e-commerce) aligns with UNCITRAL Model Law on Electronic Commerce
• AML/CFT legislation aligns with FATF standards and the Egmont Group
• Colombia is an OECD accession candidate -- domestic legislation increasingly aligns with OECD privacy and competition standards

Colombia participates in OAS (Organisation of American States) legal frameworks, the Andean Community (CAN) supranational legal order, and Pacific Alliance trade agreements. CAN decisions have direct effect in Colombian law -- similar in structure to EU secondary legislation.

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

Note: Cross-references reflect alignment and treaty relationships. Colombia adopts its own legislative approach shaped by its civil law tradition, constitutional framework (particularly the Corte Constitucional's tutela jurisprudence), and participation in CAN and OAS frameworks.

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Colombian government sources. However:

• This is a research tool, not a substitute for professional legal counsel
• Court case coverage in the free tier is not yet included -- consult the Corte Constitucional, Corte Suprema, and Consejo de Estado directly for case law
• Verify critical citations against primary sources before filing
• Departmental and municipal legislation is not included -- this covers national legislation only
• Initial release: statute coverage is being expanded; not all national laws may yet be present

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. Consult Consejo Superior de la Judicatura guidelines on AI use in legal practice.

About Ansvar Systems

We build AI-accelerated compliance and legal research tools for the global market. This MCP server started as our internal reference tool -- turns out everyone building compliance tools has the same research frustrations.

So we're open-sourcing it. Navigating Colombia's comprehensive code system shouldn't require a law degree.
