# Firmenbuch — AI Connector Firmenbuch publishes 13 MCP tools to Claude. Marketplace availability, tool surface, verification tier, and what Node8 measured against the live endpoint. Source: https://node8.ai/ai-connectors/finance/firmenbuch/ --- [AI Connectors](https://node8.ai/ai-connectors/) · [Finance](https://node8.ai/ai-connectors/finance/) # Firmenbuch Austrian company register data with annual accounts and ratios Listed in Claude · 13 published tools · Community-listed [Claude connector docs](https://www.agentic-firmenbuch.at/onboarding.html) [agentic-firmenbuch.at](https://www.agentic-firmenbuch.at/) Overview ## What Firmenbuch does The Firmenbuch is Austria's official company register, and this connector reaches both the registration data and the annual accounts filed against it. Companies can be searched and ranked by name, location, ONACE industry code, legal form, size class or financial ratio. A full profile returns year-by-year balance sheet, profit and loss, and calculated ratios. From there a company can be compared against peers in the same size class, or aggregated cohort statistics built. A daily change feed tracks management changes, capital increases and registered office moves. The listing is written in German. Community tier, documentation published. ### Who it is for Analysts and researchers working with Austrian company filings and financials. ### Tool surface The endpoint asks for credentials first, so thirteen is the listing's count. Company search and ranking, full profiles with accounts, peer comparison, cohort statistics and a daily change feed are the groupings described. Availability ## Where Firmenbuch is listed Firmenbuch is listed in the Claude connectors directory only. Agentic-Firmenbuch has no app under the same domain in the ChatGPT directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them. The MCP server behind a Claude connector is usually the same server a ChatGPT app would need, so the absence is a distribution decision rather than a technical one. Claude listing ## In the Claude connectors directory Firmenbuch publishes 13 tools to Claude. That is a mid-sized surface: 54.3% of the 1,253 Claude-listed connectors expose fewer. The median Claude-listed connector filed under Finance publishes 12, so this one runs one tool above its bucket's median and ranks 69th of 159 by tool count. It falls in the 11-20 tools band, which holds 22.5% of the Claude directory. Firmenbuch publishes a remote MCP endpoint. Claude connects to it over HTTP; there is nothing to install locally. Every connector in the Claude directory is remote, all 1,253 of them, so transport is not a differentiator there. Publisher Agentic-Firmenbuch Verification Community-listed (61.5% of the Claude directory) Filed under Financial Services Endpoint `https://mcp.agentic-firmenbuch.at/mcp` Documentation [Publisher setup docs](https://www.agentic-firmenbuch.at/onboarding.html) Published tools 13 · 11-20 tools band Depth rank in Finance 69 of 159 Snapshot August 2026 Firmenbuch is community-listed in the Claude directory, the tier 770 of 1,253 connectors sit in (61.5%). It is the default for a self-published server, and says nothing either way about quality.
