$npx -y regionfetch-mcp@0.1.1 REGION_FETCH_WALLET_PRIVATE_KEY · secret — Private key of a funded Base wallet. The server signs one fresh x402 authorization per tool call. Keep it in the host's env block; it is never a tool argument.
REGION_FETCH_MAX_PAYMENT — Per-payment ceiling, for example "$0.10". Use "off" to disable the cap.
REGION_FETCH_BASE_URL — Deployment origin.
REGION_FETCH_PAYMENT_SIGNATURE · secret — A single pre-made x402 authorization. Funds exactly one request, so this is for one-shot testing only; prefer the wallet key.
