Tools
This server runs locally, so its tools are listed by your MCP client once it starts.
Environment variables
| Name | Description |
|---|---|
SCHEMASURE_API_URLOptional | Base URL of SchemaSure. Text has free V1 evaluation without a wallet; image extraction is V2-only and always requires a wallet. |
SCHEMASURE_TIMEOUT_MSOptional | Per-call request timeout in milliseconds. |
SCHEMASURE_PRIVATE_KEYOptional, secret | Optional EVM key for a dedicated spending wallet. Signs x402 Base or MPP Tempo payments locally; never sent to SchemaSure. |
SCHEMASURE_MAX_PRICE_USDOptional | Client-side spend cap in USD per call (paid mode). The client refuses to pay more than this, even if the server advertises a higher price. |
SCHEMASURE_PAYMENT_PROTOCOLOptional | Payment protocol: x402 (USDC on Base) or mpp (USDC.e on Tempo). Signing stays local. |
