Tools

This server runs locally, so its tools are listed by your MCP client once it starts.

Environment variables

Name	Description
`K_DATA_PRIVATE_KEY` Required, secret	Private 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_USD` Optional	Hard cap on cumulative spend for the session. The server refuses any call that would exceed it.
`K_DATA_BASE_URL` Optional	Point at a different K-Data deployment.
