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

org).

Setup: NO API KEY REQUIRED. Just install the connector. The base URL is https://nominatim.openstreetmap.org.

HOWEVER — usage policy you MUST respect (otherwise you'll get banned):

  1. Max 1 request per second per IP. The connector does NOT throttle for you — your agent must self-limit. For bulk usage, run a self-hosted Nominatim or use a paid Nominatim host.
  2. User-Agent header REQUIRED — every request must identify you. The connector pins User-Agent: AnythingMCP (https://anythingmcp.com) automatically.
  3. No heavy bulk geocoding — if you need >100 requests/hour, switch to MapTiler / OpenCage / Mapbox / Google.

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 Claude 中添加连接器

推荐路径 — 在 claude.ai web 上工作,无需触碰任何配置文件。

  1. 打开 claude.ai/customize/connectors
  2. 点击 "Add custom connector"
  3. 填入:
    • Name: Nominatim (OpenStreetMap)
    • URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → 粘贴你的 MCP API key (来自 AnythingMCP → Profile → MCP API Keys → New Key)
  4. 点击 Connect 授权。
