Environment / auth

EVM_BASE_PRIVATE_KEY
secret
Base-mainnet private key holding a little USDC, used to pay per call. Leave unset to run in preview-only mode, where every paid tool returns the free preview and the exact price instead. Gas is sponsored by the facilitator, so the wallet needs USDC and no ETH. Use a throwaway key.
SCALPMCP_MAX_PRICE_USD
Refuse any single call quoted above this many dollars. Defaults to 0.10. Checked before anything is signed, so a refusal costs nothing.
SCALPMCP_BUDGET_USD
Refuse once this process has spent this many dollars in total. Defaults to 2.00.
