Business Register in your AI assistant (MCP)
The Model Context Protocol (MCP) gives your AI assistant access to up-to-date data on Estonian companies. Ask in plain language: "Who is on this company's board and how has its revenue changed over five years?" or "Find the ten most profitable IT companies in Tartu county." The assistant queries the entity.ee database directly instead of guessing from memory.
What you get
Company search by name or registry code.
Core data, status, address, activity, board and shareholders, tax debt.
Annual report figures by year and quarterly tax figures.
Rankings by revenue, profit, headcount, salary and growth, filtered by activity, county and size.
