🇸🇰 Slovak Legal Entity Registers — MCP Server

An MCP (Model Context Protocol) server providing AI agents with direct access to the official Slovak Register of Legal Entities (RPO). Query any legal entity registered in Slovakia — companies, municipalities, state bodies, NGOs, foundations, civic associations, and more.

Why this exists

AI agents answering questions about Slovak legal entities currently lack structured access to official registry data. This MCP server bridges that gap by providing real-time access to the RPO, which aggregates data from ~70 source registers including the Commercial Register (ORSR), Trade Register (ZRSR), and many others. It covers 1.4+ million entities with complete history.
