CORPUS · JURISDICTIONS · SCOPES

What connects to your assistant

Scope	Coverage	Status
@eu	EU law via EUR-Lex — regulations, directives, treaties, case law; citation graph and in-force verification.	Active
@hr	Croatian legislation (Narodne novine) — consolidated texts with historical versions, official-gazette publications, law-area taxonomy, and court decisions.	Active
@fr	French codified law (Legifrance/LEGI) — available code titles with article-level retrieval.	Active
@de	German federal legislation (Gesetze im Internet); recorded consolidation snapshots.	Active
@si	Slovenian legislation (PISRS); available article versions and validity intervals.	Active
@nl	Dutch legislation (wetten.overheid.nl); available article versions.	Active

Capabilities differ by jurisdiction. EU document text is available in English; point-in-time EU article retrieval is not supported. Croatian, French, Slovenian and Dutch article retrieval supports historical versions where available. German snapshots do not establish past-date validity. Whole-document retrieval covers Croatia, Germany, Slovenia and the Netherlands; chapter retrieval is Croatian-only. Amendment history and citation relationships depend on the available source data. Use list_scopes to inspect current capabilities, and a scope parameter or scoped document URI to select a jurisdiction.

TOOLS AVAILABLE VIA MCP

Legal research tools

Document tools return available references in a sources array with titles and available authoritative links (EUR-Lex, Narodne novine, Legifrance) so your assistant can render clickable citations. Tools retrieve legal information; usage is counted against your existing account allowance. The full tool reference is generated from the live server.

How to connect

Microsoft 365 Copilot, Teams & Word

EULEX.AI is published as an agent on Microsoft Marketplace. You need a Microsoft 365 work or school account with Microsoft 365 Copilot or Microsoft 365 Copilot Chat, and a free EULEX account.

1. In the Microsoft 365 Copilot app (web or desktop), open Agents → All agents, search for EULEX.AI and select Add.
2. Open EULEX.AI and ask a legal question. The first time it looks something up, Copilot asks you to sign in — use your EULEX account.
3. Confirm when Copilot asks to use EULEX.AI. Answers link to the official sources (EUR-Lex, Narodne novine, Legifrance) where available.

Teams — EULEX.AI is one Microsoft 365 app, so the agent you added is also available in Copilot in Teams. To add it from Teams, use Add in Microsoft Teams or search for EULEX.AI in Apps and select Add.
Word & PowerPoint — on the Home tab select Copilot, open the menu at the top left of the Copilot pane → Get Agents, and add EULEX.AI. You can also type @EULEX.AI in the Copilot pane.

Seeing Request approval, or can't find the agent? Your organization controls third-party agents. A Microsoft 365 admin can allow it in the Microsoft 365 admin center (Agents → Settings → Agent and plugin access: allow agents built by external publishers; then Agents → All agents → EULEX.AI → Install or Unblock) and, for Teams, in the Teams admin center (Teams apps → Manage apps → allow EULEX.AI).

Claude (Connectors Directory)

1. Open the EULEX.AI listing in the Claude Connectors Directory, or in Claude go to Customize → Connectors, click + and search for EULEX.AI.
2. Select Connect and sign in with your EULEX account (free to create).
3. Ask a legal question — Claude uses EULEX.AI when relevant. Once connected, the connector is available in Claude on the web, desktop and mobile.

On Team and Enterprise plans, an Owner or Primary Owner first enables the connector for the organization (Organization settings → Connectors); each member then connects with their own EULEX account.

Other MCP clients

1. Register a free account at max.eulex.ai
2. Add https://mcp.eulex.ai/mcp in Claude, ChatGPT, Copilot Studio, or any MCP client
3. Authorize via the sign-in popup — your client handles the OAuth flow
4. Start querying EU and supported national law directly from your assistant

Per client

Claude (claude.ai) — use the Connectors Directory listing; to add the URL manually instead: Customize → Connectors → + → Add custom connector.
Microsoft Copilot Studio — Tools → Add a tool → Model Context Protocol → OAuth 2.0 → Dynamic discovery.
ChatGPT — Settings → Security and login → turn on Developer mode, then Plugins → + → enter a name and the server URL → Create. In Business/Enterprise workspaces an admin enables developer mode first.

Claude Code — run in your terminal, then sign in via /mcp:

claude mcp add --transport http eulex https://mcp.eulex.ai/mcp

Cursor — ~/.cursor/mcp.json or .cursor/mcp.json:

{
  "mcpServers": {
    "eulex": { "url": "https://mcp.eulex.ai/mcp" }
  }
}

VS Code — .vscode/mcp.json (or MCP: Open User Configuration):

{
  "servers": {
    "eulex": { "type": "http", "url": "https://mcp.eulex.ai/mcp" }
  }
}

Known limitations

Croatian case-law semantic recall grows as the decision-embedding backfill progresses. @fr currently covers codified law (articles of codes); French case law is not included yet. Responses are served in the language of the underlying corpus; the agent layer handles translation.

EULEX.AI provides search over EU and supported national legal sources for informational purposes. Always verify with official EUR-Lex, Narodne novine, and Legifrance sources. Not legal advice.
