tropia.pl MCP server and API: Polish company data from KRS

Remote Model Context Protocol server and REST API by tropia.pl, the Polish company intelligence service built on the National Court Register (KRS).

• 1.2 million entities from KRS (913,000 active): companies, foundations, associations, cooperatives

• Current and historical connections: board members, supervisory boards, shareholders and proxies with dates from/to: who ran or owned a company in the past, not only today

• Registry change history from KRS and the Court and Economic Monitor (MSiG)
