Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
REGION_FETCH_WALLET_PRIVATE_KEYOptional, 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_PAYMENTOptional | Per-payment ceiling, for example "$0.10". Use "off" to disable the cap. |
REGION_FETCH_BASE_URLOptional | Deployment origin. |
REGION_FETCH_PAYMENT_SIGNATUREOptional, secret | A single pre-made x402 authorization. Funds exactly one request, so this is for one-shot testing only; prefer the wallet key. |
