This one needs environment variables set before it will start: CHEAPERESIM_API_TOKEN (Optional read-only CheapereSIM API token. Without it the five plan-search tools work normally. With it, two extra tools can list the eSIMs on your account and their remaining data. Create one at https://cheaperesim.com/dashboard/api-tokens), CHEAPERESIM_API_BASE (Override the API base URL. Defaults to https://cheaperesim.com and only needs changing for local development.), CHEAPERESIM_TIMEOUT_MS (Per-request timeout in milliseconds. Defaults to 10000.). The author declared them in the registry entry; get the values from the project itself.
