  "markdown": "# Bulgarian Law MCP Server\n\n<!-- ANSVAR-CTA-BEGIN -->\n> **The Bulgarian 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 Lex.bg 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/Bulgarian-law-mcp?style=social)](https://github.com/Ansvar-Systems/Bulgarian-law-mcp)\n[![CI](https://github.com/Ansvar-Systems/Bulgarian-law-mcp/actions/workflows/ci.yml/badge.svg)](https://github.com/Ansvar-Systems/Bulgarian-law-mcp/actions/workflows/ci.yml)\n[![Daily Data Check](https://github.com/Ansvar-Systems/Bulgarian-law-mcp/actions/workflows/check-updates.yml/badge.svg)](https://github.com/Ansvar-Systems/Bulgarian-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-17%2C103-blue)](docs/EU_INTEGRATION_GUIDE.md)\n\nQuery **1,997 Bulgarian statutes** -- from the Закон за защита на личните данни (ЗЗЛД) and Наказателен кодекс to the Граждански процесуален кодекс, Търговски закон, and more -- directly from Claude, Cursor, or any MCP-compatible client.\n\nIf you're building legal tech, compliance tools, or doing Bulgarian 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\nBulgarian legal research is scattered across Lex.bg, the Държавен вестник (State Gazette), and EUR-Lex. Whether you're:\n- A **lawyer** validating citations in a brief or contract\n- A **compliance officer** checking if a statute is still in force\n- A **legal tech developer** building tools on Bulgarian law\n- A **researcher** tracing legislative provisions across 1,997 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 Bulgarian law **searchable, cross-referenceable, and AI-readable**.\n\n---\n\n## Example Queries\n\nOnce connected, just ask naturally:\n\n- *\"Търсене 'защита на личните данни' -- какви задължения предвижда ЗЗЛД?\"*\n- *\"Действа ли Наказателният кодекс в актуалния му вид?\"*\n- *\"Намери разпоредби за търговски дружества в Търговския закон\"*\n- *\"Кои европейски актове са въведени чрез Закона за електронното управление?\"*\n- *\"Кои български закони прилагат GDPR?\"*\n- *\"Потвърди цитат: ЗЗЛД чл. 6, ал. 1\"*\n- *\"Изгради правна позиция относно задълженията за уведомяване при нарушения на сигурността\"*\n- *\"Съответства ли българското законодателство на изискванията на NIS2?\"*\n\n---\n\n## What's Included\n\n| Category | Count | Details |\n|----------|-------|---------|\n| **Statutes** | 1,997 statutes | Comprehensive Bulgarian legislation from parliament.bg |\n| **Provisions** | 17,103 sections | Full-text searchable with FTS5 |\n| **EU Cross-References** | Included | Directives and regulations linked to Bulgarian transpositions |\n| **Database Size** | 93 MB | Optimized SQLite, portable |\n| **Daily Updates** | Automated | Freshness checks against Lex.bg / Държавен вестник |\n\n**Verified data only** -- every citation is validated against official sources (parliament.bg, Lex.bg). Zero LLM-generated content.\n\n---\n\n## See It In Action\n\n### Why This Works\n\n**Verbatim Source Text (No LLM Processing):**\n- All statute text is ingested from official Bulgarian parliamentary and legislative sources\n- Provisions are returned **unchanged** from SQLite FTS5 database rows\n- Zero LLM summarization or paraphrasing -- the database contains statute text, not AI interpretations\n\n**Smart Context Management:**\n- Search returns ranked provisions with BM25 scoring (safe for context)\n- Provision retrieval gives exact text by statute + article/section reference\n- Cross-references help navigate without loading everything at once\n\n**Technical Architecture:**\n```\nparliament.bg / Lex.bg → Parse → SQLite → FTS5 snippet() → MCP response\n                            ↑                      ↑\n                    Provision parser        Verbatim database query\n```\n\n### Traditional Research vs. This MCP\n\n| Traditional Approach | This MCP Server |\n|---------------------|-----------------|\n| Search Lex.bg by statute name | Search by plain Bulgarian: *\"лични данни съгласие\"* |\n| Navigate multi-chapter statutes manually | Get the exact provision with context |\n| Manual cross-referencing between laws | `build_legal_stance` aggregates across sources |\n| \"Is this statute still in force?\" → check manually | `check_currency` tool → answer in seconds |\n| Find EU basis → dig through EUR-Lex | `get_eu_basis` → linked EU directives instantly |\n| Check multiple sites for updates | Daily automated freshness checks |\n| No API, no integration | MCP protocol → AI-native |\n\n**Traditional:** Search Lex.bg → Download PDF → Ctrl+F → Cross-reference → Check EUR-Lex for EU basis → Repeat\n\n**This MCP:** *\"Кои разпоредби на ЗЗЛД въвеждат чл. 9 от GDPR за специалните категории данни?\"* → Done.\n\n---\n\n## Available Tools (13)\n\n### Core Legal Research Tools (8)\n\n| Tool | Description |\n|------|-------------|\n| `search_legislation` | FTS5 full-text search across 17,103 provisions with BM25 ranking |\n| `get_provision` | Retrieve specific provision by statute + article/section reference |\n| `validate_citation` | Validate citation against database -- zero-hallucination check |\n| `build_legal_stance` | Aggregate citations from multiple statutes for a legal topic |\n| `format_citation` | Format citations per Bulgarian conventions (full/short/pinpoint) |\n| `check_currency` | Check if statute is in force, amended, or repealed |\n| `list_sources` | List all available statutes with metadata and data provenance |\n| `about` | Server info, capabilities, dataset statistics, and coverage summary |\n\n### EU Law Integration Tools (5)\n\n| Tool | Description |\n|------|-------------|\n| `get_eu_basis` | Get EU directives/regulations that underpin a Bulgarian statute |\n| `get_bulgarian_implementations` | Find Bulgarian laws implementing a specific EU act |\n| `search_eu_implementations` | Search EU documents with Bulgarian implementation counts |\n| `get_provision_eu_basis` | Get EU law references for a specific provision |\n| `validate_eu_compliance` | Check implementation status of Bulgarian statutes against EU directives |\n\n---\n\n## EU Law Integration\n\nBulgaria is an EU member state. Bulgarian legislation directly transposes EU directives and implements EU regulations, creating a traceable mapping between Bulgarian and EU law.\n\nKey areas of EU-Bulgarian law alignment:\n\n- **GDPR (2016/679)** -- implemented via the Закон за защита на личните данни (ЗЗЛД, amended 2019)\n- **NIS2 Directive (2022/2555)** -- transposed into Bulgarian cybersecurity legislation\n- **eIDAS Regulation (910/2014)** -- applicable directly; supplemented by the Закон за електронния документ и електронните удостоверителни услуги\n- **DORA (2022/2554)** -- financial sector digital resilience obligations\n- **AI Act (2024/1689)** -- EU regulation applicable directly across all member states\n- **AML Directives** -- implemented via Bulgarian anti-money laundering legislation\n\nThe EU bridge tools provide bi-directional lookup: find which Bulgarian statutes implement a given EU act, or find which EU acts underpin a given Bulgarian provision.\n\n| Metric | Value |\n|--------|-------|\n| **EU Member State** | Since 2007 |\n| **Legal System** | Civil law (continental European tradition) |\n| **Official Gazette** | Държавен вестник (dv.parliament.bg) |\n| **EUR-Lex Integration** | Automated metadata fetching |\n\nSee [EU_INTEGRATION_GUIDE.md](docs/EU_INTEGRATION_GUIDE.md) for detailed documentation.\n\n---\n\n## Data Sources & Freshness\n\nAll content is sourced from authoritative Bulgarian legal databases:\n\n- **[parliament.bg](https://www.parliament.bg/)** -- National Assembly of Bulgaria, official legislation database\n- **[Lex.bg](https://lex.bg/)** -- Consolidated Bulgarian legislation\n- **[Държавен вестник](https://dv.parliament.bg/)** -- Official State Gazette (primary legislative publication)\n- **[EUR-Lex](https://eur-lex.europa.eu/)** -- Official EU law database (metadata only)\n\n### Automated Freshness Checks (Daily)\n\nA [daily GitHub Actions workflow](.github/workflows/check-updates.yml) monitors all data sources:\n\n| Source | Check | Method |\n|--------|-------|--------|\n| **Statute amendments** | Lex.bg / parliament.bg comparison | All 1,997 statutes checked |\n| **New statutes** | Държавен вестник publications (90-day window) | Diffed against database |\n| **EU reference staleness** | Git commit timestamps | Flagged if >90 days old |\n\n---\n\n## Security\n\nThis project uses multiple layers of automated security scanning:\n\n| Scanner | What It Does | Schedule |\n|---------|-------------|----------|\n| **CodeQL** | Static analysis for security vulnerabilities | Weekly + PRs |\n| **Semgrep** | SAST scanning (OWASP top 10, secrets, TypeScript) | Every push |\n| **Gitleaks** | Secret detection across git history | Every push |\n| **Trivy** | CVE scanning on filesystem and npm dependencies | Daily |\n| **Docker Security** | Container image scanning + SBOM generation | Daily |\n| **Socket.dev** | Supply chain attack detection | PRs |\n| **OSSF Scorecard** | OpenSSF best practices scoring | Weekly |\n| **Dependabot** | Automated dependency updates | Weekly |\n\nSee [SECURITY.md](SECURITY.md) for the full policy and vulnerability reporting.\n\n---\n\n## Important Disclaimers\n\n### Legal Advice\n\n> **THIS TOOL IS NOT LEGAL ADVICE**\n>\n> Statute text is sourced from official Bulgarian legislative publications (parliament.bg, Lex.bg).
