lahend.ee MCP server
Free, no-API-key MCP server for Estonian law: court decisions, legislation
paragraph by paragraph, and EU law in Estonian - with the citation index that
links them to each other.
https://lahend.ee/api/lahend-mcp/mcp (streamable HTTP)
https://lahend.ee/api/lahend-mcp/sse (SSE)
No key, no sign-up, no rate limit worth mentioning. Data comes from Riigi
Teataja, EUR-Lex and HUDOC; company links come from the Estonian Business
Register via nimistu.ee.
What it can do
Legislation is served in full, not just case law - each paragraph is
addressable on its own, with every ruling that has ever cited it. That link is
the point of the server: 3.05 million citations extracted from the decision
texts, so you can ask what a statute means in practice rather than what it
says.
The corpus is 564,503 rulings. Citations were extracted from 324,968 of
them - the rest either cite no statute or state it in a form the extractor does
not resolve. Two further coverage limits are worth knowing before you rely on a
negative result:
- Companies are linked on ~19% of rulings. Parties are matched by registry
code found in the decision text, and many judgments name a company without
ever stating its code. An empty
companies array means no code was found -
not that no company was involved.
- ~26% of rulings carry no
asja_kategooria. Filtering search_rulings by
category silently excludes them; list_categories reports the
uncategorised count alongside the per-category totals.

Any client that takes a remote MCP URL works the same way. search and
fetch are present so the ChatGPT and Claude connector UIs work out of the
box; the named tools above are better when you know what you want.
