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

Schritt 3 — Connector in Gemini hinzufügen

Gemini CLI liest MCP-Server aus ~/.gemini/settings.json (oder %APPDATA%\gemini\settings.json unter Windows). Hinzufügen:

{
  "mcpServers": {
    "anythingmcp": {
      "httpUrl": "https://cloud.anythingmcp.com/mcp",
      "headers": { "Authorization": "Bearer YOUR_MCP_API_KEY" }
    }
  }
}
  1. Hole deinen MCP API Key aus AnythingMCP → Profil → MCP API Keys → Neuer Key.
  2. Speichern und gemini neu starten.
  3. /mcp in Gemini CLI ausführen — OpenPLZ Germany sollte als verfügbar gelistet sein.
  4. Vertex AI Studio: https://cloud.anythingmcp.com/mcp im tools-Array der Anfrage mit demselben Bearer-Header übergeben.
