Environment variables
  • K_DATA_PRIVATE_KEYrequiredsecretPrivate key of a dedicated wallet holding USDC on Base. Each tool call spends from it. No ETH needed - x402 settles off-chain and the facilitator pays gas.
  • K_DATA_MAX_SPEND_USDHard cap on cumulative spend for the session. The server refuses any call that would exceed it.

A starting point — check the repository for exact arguments and setup. Restart your client after editing the config.
