mcp-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.

eu_articleA
Read-onlyIdempotent

Pelny tekst artykulu (verbatim) po identyfikatorze regulacji i numerze artykulu, wraz z tytulem i rozdzialem. Bledy: out_of_scope (regulacja poza 6 ICP), missing_arg (brak article_number), not_found (artykul/regulacja nie ma w snapshot).

Inputs: regulation (required), article_number (required).

eu_check_applicabilityA
Read-onlyIdempotent

Ktore z 6 regulacji UE dotycza danego sektora (i opcjonalnie podsektora). Zwraca reguly stosowalnosci z poziomem pewnosci i artykulem-podstawa. To wskazowka ekspercka, nie wiazaca ocena prawna. Bledy: missing_arg (brak sector), corpus_error.

Inputs: sector (required), subsector.

eu_compareA
Read-onlyIdempotent

Porownanie tego samego zagadnienia w kilku regulacjach naraz. Dla kazdej regulacji zwraca najlepiej pasujacy artykul (snippet verbatim). Np. obowiazek zgloszenia incydentu w DORA vs NIS2 vs CRA. Bledy: empty_query, corpus_error.

Inputs: query (required), regulations.

eu_evidenceA
Read-onlyIdempotent

Artefakty dowodowe (audit) wymagane przez regulacje - jaki dokument/log/certyfikat udowadnia zgodnosc, dla jakiego artykulu, z pytaniami audytora. Opcjonalnie zawezone do jednego artykulu. Bledy: out_of_scope, corpus_error.

Inputs: regulation (required), article.

eu_searchA

Inputs: query (required), limit, regulations.

    TDQS

    A4.1/5.0

    Scored across 5 tools

    Disambiguation5/5

    Each tool has a clearly distinct purpose: eu_article retrieves a specific article by ID, eu_check_applicability determines which regulations apply to a sector, eu_compare compares topics across regulations, eu_evidence provides audit evidence, and eu_search performs full-text search. There is no ambiguity between them.

    Naming Consistency4/5

    All tools use the 'eu_' prefix, but the second part mixes verb and noun forms (e.g., eu_article vs eu_check_applicability). While readable and predictable, the pattern is not perfectly consistent, which lowers the score slightly.

    Tool Count5/5

    With 5 tools, the server is well-scoped for its purpose of querying EU compliance regulations. Each tool provides essential functionality without redundancy or unnecessary bloat.

    Completeness4/5

    The tool set covers key operations: retrieving articles, checking applicability, comparing regulations, obtaining evidence, and searching. Missing a tool to list all articles by regulation, but that can be approximated via search. Minor gap, but overall coverage is solid.
