OpenWeather + Claude

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

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

OPENWEATHER_API_KEY

Step 1 — Get credentials

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)

Step 2 — Install the adapter

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

Step 3 — Add the connector in Claude

Recommended path — works on claude.ai web without editing any config file.

  1. Open claude.ai/customize/connectors.
  2. Click "Add custom connector".
  3. Fill in:
    • Name: OpenWeather
    • URL: https://cloud.anythingmcp.com/mcp
    • Authentication: Bearer token → paste your MCP API key (from AnythingMCP → Profile → MCP API Keys → New Key)
  4. Click Connect to authorize.
