EU Regulations MCP Server

The EUR-Lex alternative for the AI age.

Query 37 EU regulations — from GDPR and AI Act to DORA, MiFID II, eIDAS, Medical Device Regulation, and more — directly from Claude, Cursor, or any MCP-compatible client.

If you're building digital products, financial services, healthcare tech, or connected devices for the European market, this is your compliance reference.

Built by Ansvar Systems — Stockholm, Sweden

Why This Exists

EU compliance is scattered across EUR-Lex PDFs, official journals, and regulatory sites. Whether you're:

• A developer implementing GDPR data rights or NIS2 incident reporting
• A product team navigating AI Act risk assessments or Medical Device conformity
• A compliance officer mapping ISO 27001 to DORA requirements
• A legal researcher comparing PSD2 authentication vs. eIDAS trust services

...you shouldn't need a law degree and 47 browser tabs. Ask Claude. Get the exact article. With context.

This MCP server makes EU regulations searchable, cross-referenceable, and AI-readable.

Why This Works

Verbatim Source Text (No LLM Processing):

• All article text is ingested from EUR-Lex/UNECE official sources
• Snippets are returned unchanged from SQLite FTS5 database rows
• Zero LLM summarization or paraphrasing — the database contains regulation text, not AI interpretations
• Note: HTML-to-text conversion normalizes whitespace/formatting, but preserves content

Smart Context Management:

• Search returns 32-token snippets with highlighted matches (safe for context)
• Article retrieval warns about token usage (some articles = 70k tokens)
• Cross-references help navigate without loading everything at once

Technical Architecture:

EUR-Lex HTML → Parse → SQLite → FTS5 snippet() → MCP response
                  ↑                    ↑
           Formatting only      Verbatim database query

Example: EUR-Lex vs. This MCP

| EUR-Lex | This MCP Server | |---------|-----------------| | Search by CELEX number | Search by plain English: "incident reporting timeline" | | Navigate 100+ page PDFs | Get the exact article with context | | Manual cross-referencing | compare_requirements tool does it instantly | | "Which regulations apply to me?" → research for days | check_applicability tool → answer in seconds | | Copy-paste article text | Article + definitions + related requirements | | Check 37 sites for updates | Daily automated freshness checks | | No API, no integration | MCP protocol → AI-native |

EUR-Lex example: Download DORA PDF → Ctrl+F "incident" → Read Article 17 → Google "What's a major incident?" → Cross-reference NIS2 → Repeat for 5 regulations

This MCP: "Compare incident reporting requirements across DORA, NIS2, and CRA" → Done.

⚠️ Important Disclaimers

Legal Advice

🚨 THIS TOOL IS NOT LEGAL ADVICE 🚨

Regulation text is sourced verbatim from EUR-Lex and UNECE (official public sources). However:

• Control mappings (ISO 27001, NIST CSF) are interpretive aids, not official guidance
• Applicability rules are generalizations, not legal determinations
• Cross-references are research helpers, not compliance mandates

Always verify against official sources and consult qualified legal counsel for compliance decisions.

Token Usage

⚠️ Context Window Warning

Some articles are very large (e.g., MDR Article 123 = ~70,000 tokens). The MCP server:

• Search tool: Returns smart snippets (safe for context)
• Get article tool: Returns full text (may consume significant tokens)
• Recommendation: Use search first, then fetch specific articles as needed

Claude Desktop has a 200k token context window. Monitor your usage when retrieving multiple large articles.

ISO Standards Copyright

No copyrighted ISO standards are included. Control mappings reference ISO 27001:2022 control IDs only (e.g., "A.5.1", "A.8.2"). The actual text of ISO standards requires a paid license from ISO. This tool helps map regulations to controls but doesn't replace the standard itself.
