The Austrian company register in your AI tool
Official company and balance-sheet data from the Austrian Firmenbuch – directly in Claude, Cursor, VS Code, GitHub Copilot and any MCP-capable AI assistant. Ask for company data in plain language and get verified, source-backed answers – no hallucinations.
Firmenbuch in Claude
Fastest with Claude Cowork: add the connector https://mcp.agentic-firmenbuch.at/mcp and sign in by email – no API key needed. Or in Claude Desktop / claude.ai under Settings → Connectors → Add custom connector, use the same URL. Then ask, e.g.: “Find active Austrian GmbHs in Upper Austria with a balance-sheet total above €5 million, sorted by revenue.”
Firmenbuch in Cursor
Add an HTTP MCP server to Cursor’s config (~/.cursor/mcp.json) – URL https://mcp.agentic-firmenbuch.at/mcp, header X-API-Key: YOUR_API_KEY (get a free key by email). Then query Austrian company data, ratios and peers right in the editor.
Firmenbuch in VS Code & GitHub Copilot
VS Code and GitHub Copilot (agent mode) support MCP servers. Add the remote MCP https://mcp.agentic-firmenbuch.at/mcp with the X-API-Key header – and run company research right next to your code.
Firmenbuch in ChatGPT
A ChatGPT app for the ChatGPT App Directory is in preparation. Until then, access works through MCP-capable tools like Claude, Cursor, VS Code and GitHub Copilot. Start for free and be notified when the ChatGPT app goes live.
