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 flow at ansvar.eu/gateway. 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).

The Wetten.overheid.nl alternative for the AI age.

Query 3,251 Dutch statutes -- from the AVG and Wetboek van Strafrecht to the Burgerlijk Wetboek, Mededingingswet, and the full BWB corpus -- directly from Claude, Cursor, or any MCP-compatible client.

If you're building legal tech, compliance tools, or doing Dutch legal research, this is your verified reference database.

Built by Ansvar Systems -- Stockholm, Sweden

Why This Exists

Dutch legal research is scattered across Wetten.overheid.nl, Rechtspraak.nl, Kamerstukken, and EUR-Lex. Whether you're:

• A lawyer validating citations in a brief or contract
• A compliance officer checking AVG obligations or Mededingingswet requirements
• A legal tech developer building tools on Dutch law
• A researcher tracing legislative history from Kamerstukken to wet

...you shouldn't need dozens of browser tabs and manual PDF cross-referencing. Ask Claude. Get the exact provision. With context.

This MCP server makes Dutch law searchable, cross-referenceable, and AI-readable.

Quick Start

Dutch Law is reachable through the Ansvar MCP Gateway at https://gateway.ansvar.eu. The gateway terminates OAuth, fans queries out across the Dutch corpus, and returns citation-grounded answers. There is no public unauthenticated endpoint.

Connect via Ansvar Gateway

Sign up at gateway.ansvar.eu for a Premium / Team / Company tier account, then point your client at the gateway:

Claude Desktop -- add to claude_desktop_config.json:

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

Claude Code:

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

GitHub Copilot -- add to VS Code settings.json:

{
  "github.copilot.chat.mcp.servers": {
    "ansvar-gateway": {
      "type": "http",
      "url": "https://gateway.ansvar.eu/mcp"
    }
  }
}

The gateway authenticates via Keycloak OAuth 2.1 with Dynamic Client Registration. On first connect your client will open a browser tab for sign-in and consent.

Run Locally (Docker)

For development or air-gapped deployments, the GHCR image ships with the prebuilt SQLite database baked in:

docker run --rm -p 3009:3009 ghcr.io/ansvar-systems/dutch-law-mcp:latest

The image self-tests via the bundled HEALTHCHECK and exits non-zero if the database is missing. Watchtower-driven fleets get automatic rolling updates on every push to main.

Example Queries

• "Is de Mededingingswet artikel 24 over misbruik van machtspositie nog van kracht?"
• "Zoek bepalingen over gegevensbescherming in de Nederlandse wet"

See It In Action

Why This Works

Verbatim Source Text (No LLM Processing):

• All statute text is ingested from Wetten.overheid.nl official sources via the BWB API
• Provisions are returned unchanged from SQLite FTS5 database rows
• Zero LLM summarization or paraphrasing -- the database contains regulation text, not AI interpretations

Smart Context Management:

• Search returns ranked provisions with BM25 scoring (safe for context)
• Provision retrieval gives exact text by BWB identifier + chapter/article
• Cross-references help navigate without loading everything at once

Technical Architecture:

Wetten.overheid.nl BWB API → Parse → SQLite → FTS5 snippet() → MCP response
                                ↑                      ↑

Traditional Research vs. This MCP

| Traditional Approach | This MCP Server | | -------------------------------------------------- | ------------------------------------------------------ | | Search Wetten.overheid.nl by wet name | Search by plain Dutch: "persoonsgegevens verwerking" | | Navigate multi-boek statutes manually | Get the exact provision with context | | Manual cross-referencing between wetten | build_legal_stance aggregates across sources | | "Is this statute still in force?" → check manually | check_currency tool → answer in seconds | | Find EU basis → dig through EUR-Lex | get_eu_basis → linked EU directives instantly | | Check Kamerstukken.nl separately | Premium get_preparatory_works → linked documents | | No API, no integration | MCP protocol → AI-native |

Traditional: Search Wetten.overheid.nl → Open BWB page → Navigate articles → Check Kamerstukken → EUR-Lex for EU basis → Repeat

This MCP: "What EU law is the basis for AVG artikel 5 about data processing principles?" → Done.

EU Law Integration

Netherlands is a founding EU member state. Dutch law directly transposes EU directives across the full acquis communautaire.

| Metric | Value | | ---------------------- | ------------------------------------------------------------- | | EU Member State | Yes (founding member, since 1958) | | GDPR Status | Directly applicable; implemented by Uitvoeringswet AVG | | Key Implementation | AVG → Uitvoeringswet Algemene verordening gegevensbescherming | | Competition Law | Mededingingswet implements EU Treaty Articles 101-102 | | ePrivacy | Telecommunicatiewet transposes ePrivacy Directive |

Dutch Law and EU Directives

• AVG (GDPR) -- GDPR is directly applicable in the Netherlands. The Uitvoeringswet AVG implements the member-state derogations and supplements. The get_eu_basis tool links AVG provisions to the underlying GDPR articles.
• ePrivacy Directive -- transposed via the Telecommunicatiewet, governing electronic communications and cookie consent.
• Competition law -- Mededingingswet aligns with EU Treaty Articles 101 (cartels) and 102 (abuse of dominance) and Commission enforcement practice.
• Trade Secrets Directive -- implemented by Wet bescherming bedrijfsgeheimen (2018).
• Financial regulation -- Wet op het financieel toezicht (Wft) transposes MiFID II, the Capital Requirements Directive, and related EU financial services directives.

The EU bridge tools provide bi-directional lookup: start from a Dutch provision to find its EU basis, or start from an EU directive to find its Dutch implementation.

See [EUINTEGRATIONGUIDE.md](docs/EUINTEGRATIONGUIDE.md) for detailed documentation.
