Paraguayan Law MCP Server

The Digesto Jurídico Paraguayo alternative for the AI age.

Query Paraguayan statutes -- from Ley 6534/2020 on data protection and the Código Penal to the Código Civil, Código del Trabajo, and more -- directly from Claude, Cursor, or any MCP-compatible client.

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

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Paraguayan legal research is scattered across digesto.senado.gov.py, bacn.gov.py, and congreso.gov.py. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking obligations under Ley 6534/2020 on data protection or MERCOSUR agreements
• A legal tech developer building tools on Paraguayan law
• A researcher tracing legislative history through 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 Paraguayan law searchable, cross-referenceable, and AI-readable.

Quick Start

Use Remotely (No Install Needed)

Connect directly to the hosted version -- zero dependencies, nothing to install.

Endpoint: https://mcp.ansvar.eu/law-py/mcp

Claude Desktop -- add to claude_desktop_config.json:

{
  "mcpServers": {
    "paraguayan-law": {
      "type": "url",
      "url": "https://mcp.ansvar.eu/law-py/mcp"
    }
  }
}

GitHub Copilot -- add to VS Code settings.json:

{
  "github.copilot.chat.mcp.servers": {
    "paraguayan-law": {
      "type": "http",
      "url": "https://mcp.ansvar.eu/law-py/mcp"
    }
  }
}

Use Locally (npm)

Claude Desktop -- add to claude_desktop_config.json:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "paraguayan-law": {
      "command": "npx",
      "args": ["-y", "@ansvar/paraguayan-law-mcp"]
    }
  }

      "command": "npx",
      "args": ["-y", "@ansvar/paraguayan-law-mcp"]
    }
  }

Example Queries

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

• "¿Qué dice la Ley 6534/2020 sobre protección de datos personales respecto al consentimiento?"
• "Buscar disposiciones sobre delitos informáticos en el Código Penal paraguayo"
• "¿Está vigente el Código del Trabajo en Paraguay?"
• "Buscar artículos sobre contratos en el Código Civil"
• "¿Qué establece la Ley de Sociedades Comerciales sobre responsabilidad de directores?"
• "Buscar legislación sobre inversión extranjera en Paraguay"
• "Validar la cita Ley 6534/2020 artículo 5"
• "What does Paraguayan data protection law 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 Paraguayan sources. Use list_sources to see current coverage, and about for the latest statistics.

Verified data only -- every citation is validated against official sources (Digesto Jurídico, BACN, Congreso Nacional). Zero LLM-generated content.

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from official Paraguayan government sources (digesto.senado.gov.py, bacn.gov.py)
• 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:

digesto.senado.gov.py / bacn.gov.py --> 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 obligaciones impone la Ley 6534/2020 a los responsables del tratamiento de datos?" -> Done.

Available Tools (13)

Core Legal Research Tools (8)

International Law Integration Tools (5)

International Law Alignment

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

• MERCOSUR -- Paraguay is a full MERCOSUR member; MERCOSUR decisions and resolutions have direct applicability
• OAS frameworks -- Organization of American States conventions and model laws
• Ley 6534/2020 aligns with international data protection principles including GDPR adequacy concepts; the get_eu_basis tool maps these for cross-reference
• Código del Trabajo aligns with ILO conventions and MERCOSUR social and labour declarations

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

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

Data Sources & Freshness

All content is sourced from authoritative Paraguayan legal databases:

• Digesto Jurídico Paraguayo -- Official consolidated law digest maintained by the Senate
• Biblioteca y Archivo Central del Congreso (BACN) -- Congressional library and archive
• Congreso Nacional -- National Congress records

Data Provenance

Automated Freshness Checks

A GitHub Actions workflow monitors Paraguayan legal sources for changes:

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

Important Disclaimers

Legal Advice

THIS TOOL IS NOT LEGAL ADVICE

Statute text is sourced from official Paraguayan 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

Client Confidentiality

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