OpenPLZ Germany + ChatGPT

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.

前提条件

完整的设置说明已内置在连接器中 (在 store 中选择连接器时可见)。所需环境变量:

(none — public API)

步骤 1 — 获取凭证

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

步骤 2 — 安装 adapter

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

步骤 3 — 在 ChatGPT 中添加连接器

ChatGPT 通过 Connectors 功能 (Plus / Pro / Team / Enterprise 套餐) 支持 MCP 服务器。免费套餐不支持自定义连接器。

打开 ChatGPT → Settings → Connectors (或点击 composer 中的 🔧 图标 → Manage connectors)。
点击 "Add custom connector"。
填入:
- Name: OpenPLZ Germany
- MCP server URL: https://cloud.anythingmcp.com/mcp
- Authentication: Bearer token → 粘贴 MCP API key
点击 Connect。
