  "markdown": "# Latvian Law MCP Server\n\n<!-- ANSVAR-CTA-BEGIN -->\n> **The Latvian law corpus is now served through the Ansvar Gateway.** Connect your AI assistant (Claude, Copilot, Cursor, custom MCP client) to `https://gateway.ansvar.eu/mcp` — one OAuth connection, free tier available, covering this corpus plus EU regulations, national law across dozens of audited jurisdictions (Europe + the US), and CVE/security intelligence, every result with a verbatim source citation. Start at https://ansvar.eu/docs/quickstart\n\n### Connect\n\n**Claude Code** (one line):\n\n```bash\nclaude mcp add ansvar --transport http https://gateway.ansvar.eu/mcp\n```\n\n**Claude Desktop / Cursor** — add to `claude_desktop_config.json` (or `mcp.json`):\n\n```json\n{\n  \"mcpServers\": {\n    \"ansvar\": {\n      \"type\": \"url\",\n      \"url\": \"https://gateway.ansvar.eu/mcp\"\n    }\n  }\n}\n```\n\n**Claude.ai** — Settings → Connectors → Add custom connector → paste `https://gateway.ansvar.eu/mcp`\n\nFirst request opens an OAuth signup flow (setup details: [ansvar.eu/docs/quickstart](https://ansvar.eu/docs/quickstart)). After signup, your client is bound to your account; tier (free / premium / team / company) determines fan-out, quota, and which downstream MCPs are reachable.\n\n---\n\n## Self-host this MCP\n\nYou can also clone this repo and build the corpus yourself. The schema,\nfetcher, and tool implementations all live here. What is not in the repo is\nthe pre-built database — TDM and standards-licensing constraints on the\nupstream sources mean we host the corpus on Ansvar infrastructure rather\nthan redistribute it as a public artifact.\n\nBuild your own: run this repo's ingestion script (entry-point varies per\nrepo — typically `scripts/ingest.sh`, `npm run ingest`, or `make ingest`;\ncheck the repo root).\n<!-- ANSVAR-CTA-END -->\n\n\n**The Latvijas Vēstnesis alternative for the AI age.**\n\n[![MCP Registry](https://img.shields.io/badge/MCP-Registry-blue)](https://registry.modelcontextprotocol.io)\n[![License](https://img.shields.io/badge/License-Apache_2.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)\n[![GitHub stars](https://img.shields.io/github/stars/Ansvar-Systems/Latvian-law-mcp?style=social)](https://github.com/Ansvar-Systems/Latvian-law-mcp)\n[![CI](https://github.com/Ansvar-Systems/Latvian-law-mcp/actions/workflows/ci.yml/badge.svg)](https://github.com/Ansvar-Systems/Latvian-law-mcp/actions/workflows/ci.yml)\n[![Daily Data Check](https://github.com/Ansvar-Systems/Latvian-law-mcp/actions/workflows/check-updates.yml/badge.svg)](https://github.com/Ansvar-Systems/Latvian-law-mcp/actions/workflows/check-updates.yml)\n[![Database](https://img.shields.io/badge/database-pre--built-green)](docs/EU_INTEGRATION_GUIDE.md)\n[![Provisions](https://img.shields.io/badge/provisions-57%2C679-blue)](docs/EU_INTEGRATION_GUIDE.md)\n\nQuery **2,249 Latvian statutes** -- from the Fizisko personu datu apstrādes likums and Krimināllikums to the Civillikums, Darba likums, and more -- directly from Claude, Cursor, or any MCP-compatible client.\n\nIf you're building legal tech, compliance tools, or doing Latvian legal research, this is your verified reference database.\n\nBuilt by [Ansvar Systems](https://ansvar.eu) -- Stockholm, Sweden\n\n---\n\n## Why This Exists\n\nLatvian legal research means navigating likumi.lv, the Latvijas Vēstnesis official gazette, and EUR-Lex for EU implementation status -- across a comprehensive system of codes and regulations. Whether you're:\n\n- A **lawyer** validating citations before the Augstākā tiesa (Supreme Court) or Satversmes tiesa (Constitutional Court)\n- A **compliance officer** checking GDPR implementation under Fizisko personu datu apstrādes likums or NIS2 requirements\n- A **legal tech developer** building tools on Latvian law\n- A **researcher** tracing EU directive transposition across 2,249 statutes\n\n...you shouldn't need dozens of browser tabs and manual cross-referencing. Ask Claude. Get the exact provision. With context.\n\nThis MCP server makes Latvian law **searchable, cross-referenceable, and AI-readable**.\n\n---\n\n## Example Queries\n\nOnce connected, just ask naturally:\n\n- *\"Ko nosaka Fizisko personu datu apstrādes likuma 25. pants par datu apstrādi?\"*\n- *\"Vai Krimināllikums ir spēkā?\"*\n- *\"Meklēt 'personas datu aizsardzība' Latvijas tiesību aktos\"*\n- *\"Kādi ES tiesību akti ir Darba likuma pamatā?\"*\n- *\"Kuri Latvijas likumi īsteno NIS2 direktīvu?\"*\n- *\"Ko paredz Civillikuma 1785. pants par saistību tiesībām?\"*\n- *\"Validēt citātu 'Fizisko personu datu apstrādes likums, 25. pants'\"*\n- *\"Salīdzināt datu aizsardzības prasības dažādās NIS2 Latvijas implementācijās\"*\n\n---\n\n## What's Included\n\n| Category | Count | Details |\n|----------|-------|---------|\n| **Statutes** | 2,249 statutes | Comprehensive Latvian legislation from likumi.lv |\n| **Provisions** | 57,679 sections | Full-text searchable with FTS5 |\n| **Premium: Case Law** | 127,042 decisions | Augstākā tiesa, Satversmes tiesa, Administratīvā tiesa (Premium tier) |\n| **Premium: Preparatory Works** | 29,516 documents | Saeima anotācijas and explanatory reports (Premium tier) |\n| **Database Size** | 131 MB | Optimized SQLite, portable |\n| **Daily Updates** | Automated | Freshness checks against likumi.lv |\n\n**Verified data only** -- every citation is validated against official sources (likumi.lv, Latvijas Vēstnesis).
