    Current German (Veranlagungszeitraum 2026) tax and social-insurance figures read from the consolidated statutes on gesetze-im-internet.de, the Bundesgesetzblatt and the BMG, DRV, BMAS, BMFSFJ and Minijob-Zentrale pages named in each figure's source — each with the German term and an English label, the quoted sentence, verifiedDate and the prior value where one exists. Categories: income-tax (Grundfreibetrag, § 32a tariff zones with their coefficients, Eingangssteuersatz, Spitzensteuersatz and Reichensteuer thresholds, Solidaritätszuschlag rate, Freigrenzen and Milderungszone), social-insurance (Beitragsbemessungsgrenzen RV/AV and KV/PV annual and monthly, Jahresarbeitsentgeltgrenze, Bezugsgröße, vorläufiges Durchschnittsentgelt, KV/RV/AV/PV Beitragssätze with employee and employer shares, durchschnittlicher Zusatzbeitrag, Kinderlosenzuschlag and Kinderabschlag, Sachsen split), minimum-wage (Mindestlohn 2026 and the fixed 2027 step), minijob (Geringfügigkeitsgrenze 2026 and 2027, Midijob upper limit), kindergeld, kinderfreibetrag (Kinderfreibetrag, BEA-Freibetrag, total per child), sparer-pauschbetrag, arbeitnehmer-pauschbetrag, entfernungspauschale.

The model (one brand, many focused servers)

There is no domain authority in MCP registries — discovery is per-listing. So this is NOT one mega-server (tool-list bloat kills those); it is one domain/repo/brand hosting separate, focused MCP endpoints, each listed individually under one namespace, cross-referencing each other:

Front door (2026-09): POST /api/mcp lists the five high-frequency tools directly plus whatchangedsince, coverage, catalogue, call. It is still not a mega-server — everything else stays behind call, capped at 9 listed tools by test. The focused servers remain live and listed.

The roadmap is ordered by (value to an AI agent) × (likelihood we can build it well). It deliberately includes the maintainer-Claude wishlist — this product is designed with Claude as the end user, by Claude:
