Install Legal Data Hunter

Install the Legal Data Hunter MCP server and verify the connection. Legal Data Hunter provides access to 18M+ legal documents across 110+ countries — case law, legislation, and doctrine — via hybrid semantic + keyword search.

Step 1: Detect environment and install

Check if running inside Claude Code:

which claude 2\>/dev/null  

If Claude Code is available, run:

claude mcp add legal-data-hunter --transport http https://legaldatahunter.com/mcp  

If not Claude Code (Cursor, VS Code, Windsurf, JetBrains, Copilot, Lawvable), run:

npx legal-data-hunter --yes  

This auto-detects the client and writes the MCP config to the correct location. It supports: Cursor, VS Code, Lawvable, Windsurf, Copilot CLI, and JetBrains (Junie).

Step 2: Verify installation

After installing, confirm the MCP server is connected. In Claude Code, reconnect MCP servers and check that Legal Data Hunter appears with its tools. The server exposes 7 tools:

Tool	Purpose
discover\_countries()	List all 110+ indexed countries with document counts
discover\_sources(country)	List available sources for a country (e.g. "FR", "DE", "EU")
search(query, ...)	Hybrid semantic + keyword search across jurisdictions
resolve\_reference(citation)	Look up a specific citation — ECLI, CELEX, article number, case number
get\_document(id)	Retrieve the full text of a document by ID
get\_filters()	List available filter options (courts, document types, date ranges)
report\_source\_issue(...)	Report a problem with a data source or request a new one

Step 3: Getting started

Once connected, here are useful first queries to try:

Explore coverage:

• Call discover_countries() to see all indexed jurisdictions and their document counts
• Call discover_sources("FR") to see French court databases, legislation sources, and doctrine

Search across jurisdictions:

• search("unfair dismissal", country="DE", doc_type="case_law") — German case law on unfair dismissal
• search("artificial intelligence regulation", country="EU") — EU legislation on AI
• search("data protection breach notification", country="UK") — UK GDPR enforcement

Resolve specific citations:

• resolve_reference("ECLI:EU:C:2014:317") — look up a CJEU decision by ECLI
• resolve_reference("32016R0679") — look up the GDPR by CELEX number
• resolve_reference("Article 49 TFEU") — find Treaty provisions

Retrieve full documents:

• Use get_document(id) with an ID returned from search or resolve_reference to get the complete text

Tips

• Natural language works: The search engine understands legal concepts, not just keywords. "Can an employer fire someone for social media posts?" works as well as "dismissal social media misconduct".
• Cross-reference: Search one jurisdiction, then use the same query in another to compare legal approaches across borders.
• Citation chains: Use resolve_reference() to find a law, then search() with that law's name to find all court decisions that cite it.
• Filters narrow results: Call get_filters() first to see what filter options are available, then pass them to search().
• Missing a source? Use report_source_issue() to request a new legal source or report a problem. New sources can be indexed in under 48 hours.
