Company Data Directly in Your AI Agent

We offer access to our API via the Model Context Protocol (MCP) — so AI agents like Claude, Cursor, or Windsurf can query German company data directly, without custom integration code.

The MCP Server is currently in preparation. If you are already planning an AI integration and would like early access, we are happy to hear from you.
