For developers & agents
Agentic-Firmenbuch is a standards-compliant MCP server, compatible with Claude, Claude Code, Cursor, VS Code and any MCP-capable AI tool. In Claude you connect in one click with no API key; for servers, CI and your own agents you use a key. The code is open source. Note: search answers respond in German.
How it works
Paste the MCP URL into Claude, Cursor or VS Code. In Claude a sign-in by email code is enough, no API key.
"Active GmbHs in Upper Austria with total assets above €5M." The agent translates that into a query across the right tools.
The matches with official figures, every row sourced from the Firmenbuch. Nothing invented.
Tools
Search the whole register by name, activity, industry, region and financial metrics; full result lists instead of single lookups.
Master data, management, multi-year balance sheet, P&L and ready-made ratios for a specific company.
Find comparable companies and benchmark one against its peer group; register events as deal signals.
Complete result lists as CSV, for CRM, pipeline or further analysis.
API key
Cursor, VS Code and Claude Code connect like Claude via an email code, with no key. An API key is only needed for CI/CD pipelines, servers, your own programs or several machines sharing one access. You create and manage keys in the web app: named, individually revocable, shown once.
