EU Regulations MCP Server

⚰️ RETIRED — folded into ansvar-mcp-fleet (2026-07-07)

This standalone repo is archived. The eu-regulations corpus now lives at Ansvar-Systems/ansvar-mcp-fleet under mcps/eu-regulations/ (fold: fleet PR #594; cutover: deploy PR #653, live 2026-07-07). Production serves the fleet-built image ghcr.io/ansvar-systems/eu-regulations with the CI-published eu-regulations-data-v2 data image — including the 7 MDR/IVDR delegated + implementing acts and the 14 robotics instruments (#109).

All new content and fixes go to the fleet monorepo (seeds in mcps/eu-regulations/seed/, build via scripts/build-chassis-db.ts). Open PRs at archive time, for the record: #110 (rail EU-law spine — port its instruments to fleet seeds), #113 (README banner, superseded by this notice), #111 (dependabot), #57 / #4 (stale). The gateway endpoint below still works — it now serves from the fleet deployment.

The EU regulations 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

Connect

Claude Code (one line):

claude mcp add ansvar --transport http https://gateway.ansvar.eu/mcp

Claude Desktop / Cursor — add to claude_desktop_config.json (or mcp.json):

{
  "mcpServers": {
    "ansvar": {
      "type": "url",
      "url": "https://gateway.ansvar.eu/mcp"
    }
  }
}

Claude.ai — Settings → Connectors → Add custom connector → paste https://gateway.ansvar.eu/mcp

First request opens an OAuth signup flow (setup details: 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.

Self-host this MCP

You can also clone this repo and build the corpus yourself. The schema, fetcher, and tool implementations all live here. What is not in the repo is the pre-built database — TDM and standards-licensing constraints on the upstream sources mean we host the corpus on Ansvar infrastructure rather than redistribute it as a public artifact.

Build your own: run this repo's ingestion script (entry-point varies per repo — typically scripts/ingest.sh, npm run ingest, or make ingest; check the repo root).

MCP server providing structured access to full-text EU regulations via Claude, Cursor, and other MCP-compatible clients.

Query EU regulations — from GDPR and AI Act to DORA, Chips Act, MiFID II, eIDAS, Medical Device Regulation, MDCG cybersecurity guidance, 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.

Example Queries

Once connected, just ask naturally:

• "What are the risk management requirements under NIS2 Article 21?"
• "How long do I have to report a security incident under DORA?"
• "Compare GDPR breach notification with NIS2 incident reporting"
• "Does the EU AI Act apply to my recruitment screening tool?"
• "What are the essential cybersecurity requirements under the Cyber Resilience Act?"
• "Which regulations apply to a healthcare organization in Germany?"
• "Map DORA ICT risk management to ISO 27001 controls"
• "What is an EU Digital Identity Wallet under eIDAS 2.0?"
• "What are my data access rights under the Data Act?"

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 64-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 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.

Directory Review Notes

Testing Account and Sample Data

This server is read-only and does not require a login account for functional review. For directory review, use the bundled dataset and these sample prompts:

• "What does NIS2 Article 21 require?"
• "Compare DORA and NIS2 incident reporting obligations."
• "Map ISO 27001 controls to DORA requirements."

Remote Authentication (OAuth 2.0)

The default server runtime is read-only and can be deployed without authentication. If you deploy a remote authenticated endpoint, use OAuth 2.0 over TLS with certificates from recognized authorities.

⚠️ 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.

Branching Strategy

This repository uses a dev integration branch. Do not push directly to main.

feature-branch → PR to dev → verify on dev → PR to main → deploy

• main is production-ready. Only receives merges from dev via PR.
• dev is the integration branch. All changes land here first.
• Feature branches are created from dev.
