🇸🇰 Slovak Business Registers — MCP Server

An MCP (Model Context Protocol) server providing AI agents with direct access to official Slovak business register data. Query company information, ownership structures, and business activities from the Register právnických osôb (RPO) — Slovakia's central register of legal entities.

Why this exists

AI agents answering questions about Slovak companies 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.
