Field notes

The remote MCP endpoint accepts connections from Claude Code and other MCP clients, with tools organized around obligations by country and business activity. The listed checks include German invoice fields under § 14 (4) UStG, marketing consent, AI disclosure wording in four languages, and live VAT ID verification through VIES. The site says its free tier stores neither inputs nor results, while higher limits and a server-side audit log are planned for paid plans.
