OpenPLZ Germany + Claude

Look up German postal codes, localities, and streets via the OpenPLZ API. Free, no authentication, based on the official Bundesanstalt für Kartographie und Geodäsie (BKG) datasets.

Voraussetzungen

Die vollständige Setup-Anleitung ist in den Connector eingebaut (im Store sichtbar, wenn du den Connector auswählst). Benötigte Umgebungsvariablen für diesen Connector:

(none — public API)

Schritt 1 — Zugangsdaten holen

This connector wraps the free OpenPLZ API for German administrative structure lookups. Useful for address validation, form autocomplete, and regional analytics.

Hierarchy: Germany → Federal state (Bundesland) → District (Kreis) → Municipality (Gemeinde) → Locality (Ort) + postal code (PLZ).

No authentication required. OpenPLZ is rate-limited (soft limit ~10 req/s) — for bulk work consider self-hosting.

Common flows:

  • Postal code → localities: openplz_lookup_postalcode
  • City + street autocomplete: openplz_search_streets
  • Full town info by AGS (Amtlicher Gemeindeschlüssel): openplz_get_locality

Schritt 2 — Adapter installieren

git clone https://github.com/HelpCode-ai/anythingmcp.git
cd anythingmcp && docker compose up -d
