Lahend MCP Server

lahend MCP — Estonian court decisions for AI assistants

Connect any MCP-compatible AI assistant (Claude, Cursor, ChatGPT, and more) to the full published case law of the Estonian courts — civil, administrative and criminal decisions from Riigi Teataja. Search the actual decision text, read a ruling in full, or pull every case involving a given company — in plain language, free, no API key, read-only.

Powered by lahend.ee, a free, ad-free court-decision search engine that indexes the Riigi Teataja corpus and links every ruling to the companies named in it (via the Estonian Business Register / nimistu.ee).

• Endpoint (Streamable HTTP): https://lahend.ee/api/lahend-mcp/mcp
• Free — no API key, no signup, read-only
• Full-text — searches the decision text, not just metadata
• Company-linked — every ruling ties to the companies it names

Why this over a Riigi Teataja API wrapper

Riigi Teataja publishes the decisions; lahend.ee makes them usable for an agent:

• Full-text search over the decision body, inflection-tolerant, with exact "quoted phrases" — not just title/metadata lookups.
• Company ↔ case-law join — rulings_by_company returns every decision naming a company by its 8-digit registry code, with each party's role (claimant / defendant). No other Estonian legal tool exposes this.
• Browsable structure — courts and areas of law with live counts, as filters.
• ChatGPT-compatible search + fetch, so the same server works across clients.
