Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
EVM_BASE_PRIVATE_KEYOptional, 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_USDOptional | Refuse any single call quoted above this many dollars. Defaults to 0.10; 0 turns spending off. Checked before anything is signed, so a refusal costs nothing. |
SCALPMCP_BUDGET_USDOptional | Refuse once this process has spent this many dollars in total. Defaults to 2.00; 0 turns spending off. |
SCALPSTREAM_STATUS_TOKENOptional, secret | For ScalpStream managed-trading subscribers only: the status token from the enrolment page (st-...), read by my_engine_status. It reads that one engine's status and can do nothing else. Leave unset otherwise. |
