Eu Compliance

MCP server exposing an offline corpus of EU law (EUR-Lex, full text) in local SQLite FTS5, with compliance tools. Snippets returned verbatim from the database (zero-LLM) - each with a CELEX id and EUR-Lex URL. Anti-hallucination by mechanism, not by trust in the model.

Scope (14 regulations, digital/data/cyber): GDPR, AI Act, DORA, NIS2, eIDAS 2.0, CRA, DSA, DMA, Data Act, DGA, LED, ePrivacy, Cybersecurity Act, CER.

Complementary to mcp-eu-sparql: that one discovers acts live (SPARQL Cellar), this one provides verbatim text + offline compliance analysis (no network at runtime).

Installation

npm install            # Node 22.5+ (node:sqlite built-in)
npm run fetch-corpus   # downloads regulations.db (~36 MB) from Ansvar (Apache-2.0)
npm run build
npm start

Configuration in the MCP client (e.g. mcp-servers.json):

{
  "name": "eu-compliance",
  "command": "node",
  "args": ["/path/to/mcp-eu-compliance/dist/index.js"]
}

Tools

Tool	Description
eu_search(query, regulations?, limit?)	Full-text (FTS5) across articles, verbatim snippets.
eu_article(regulation, article_number)	Full article text + title + chapter + CELEX.
eu_compare(query, regulations?)	The same topic across several regulations at once (e.g. incident reporting DORA vs NIS2 vs CRA).
eu_check_applicability(sector, subsector?)	Which of the 14 regulations apply to a sector, with confidence level and basis article.
eu_evidence(regulation, article?)	Evidence artifacts (audit) - which document/log/certificate proves compliance.

Each tool returns structuredContent.citations (regulation, CELEX, EUR-Lex URL, snapshot).

Examples

• "Compare incident reporting timelines across DORA, NIS2, and CRA" -> eu_compare
• "What does GDPR Article 33 require?" -> eu_article
• "Which EU regulations apply to a bank?" -> eu_check_applicability(sector=financial, subsector=bank)
• "What audit evidence does DORA Article 17 require?" -> eu_evidence

Disclaimers

• Snapshot, not the authentic source. The authentic version = Official Journal of the EU. The connector returns a point-in-time snapshot; verify currency in EUR-Lex (CELEX). Freshness -> mcp-eu-sparql (live).
• Applicability rules are expert guidance, not a binding legal assessment. Sector-specific realities may require your own analysis.
• Reference material, not legal advice.
