Frequently asked questions
Which environment variables are required and where are they set?
`OPENWEATHERMAP_API_KEY`, `IPINFO_API_KEY`, `GOOGLE_API_KEY`, and `GOOGLE_CX`. Set them in the Cloudflare Dashboard (Workers & Pages → Settings → Variables), not in `wrangler.toml`.
Can I skip a service if I don’t have its API key?
Yes. If you omit an API key, that function will return an error but the worker still works for the other services.
How does Claude communicate with this worker?
The worker implements the Model Context Protocol (MCP) over HTTPS. Claude uses the deployed worker URL automatically based on your prompt.
Are there any usage limits or rate‑limiting?
The README does not specify any built‑in limits; however, third‑party APIs (OpenWeatherMap, ipinfo.io, Google Custom Search) may impose their own quotas.
