OpenWeather + Claude

Query OpenWeather (current weather, forecasts, air quality, geocoding) from any AI agent. 6 tools, API-key auth.

前提条件

完全なセットアップ手順はコネクタ自体に組み込まれています (ストアでコネクタを選択すると表示)。必要な環境変数:

OPENWEATHER_API_KEY

ステップ 1 — 認証情報を取得

This connector wraps the OpenWeather REST API (api.openweathermap.org).

Setup:

  1. Sign up at https://openweathermap.org/users/sign_up (free tier: 60 calls/min, 1M/month).
  2. Go to https://home.openweathermap.org/api_keys → copy the default key OR create a new one labelled e.g. mcp.
  3. Wait ~10 minutes — new keys take time to activate on the free tier.
  4. Set OPENWEATHER_API_KEY.

Authentication: every request takes appid=${OPENWEATHER_API_KEY} as a query string. The adapter injects it automatically — never include it in tool arguments.

…(continued in the in-app connector instructions)

ステップ 2 — アダプターをインストール

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

ステップ 3 — Claude にコネクタを追加

推奨ルート — 設定ファイルを触らずに claude.ai web で動作します。

  1. claude.ai/customize/connectors を開きます。
  2. "Add custom connector" をクリック。
  3. 入力:
    • Name: OpenWeather
    • URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → MCP API キーを貼り付け (AnythingMCP → Profile → MCP API Keys → New Key)
  4. Connect をクリックして認可。
