OpenWeather + Cursor
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:
- Sign up at https://openweathermap.org/users/sign_up (free tier: 60 calls/min, 1M/month).
- Go to https://home.openweathermap.org/api_keys → copy the default key OR create a new one labelled e.g.
mcp. - Wait ~10 minutes — new keys take time to activate on the free tier.
- Set
OPENWEATHER_API_KEY.
Authentication: every request takes appid=${OPENWEATHER_API_KEY} as a query string. The adapter injects it automatically — never include it in tool arguments.
…(continued in the in-app connector instructions)
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in Cursor
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
Cursor reads MCP servers from ~/.cursor/mcp.json. Add this entry:
{
"mcpServers": {
"anythingmcp": {
"url": "https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID",
"headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
}
}
}
- Get your MCP API key from AnythingMCP → MCP Servers → your server → API keys.
- Save the file and restart Cursor.
- Open Cursor → Settings → MCP to verify
OpenWeatheris listed and "Connected". - Start chatting — all
