About SchemaSure — structured extraction

Extract schema-valid JSON from text/HTML or document images. Pay with x402 on Base or MPP on Tempo.

Configuration

Local server config is the same for every client. Copy it into your client’s MCP config file.

Environment variables to set
SCHEMASURE_API_URLBase URL of SchemaSure. Text has free V1 evaluation without a wallet; image extraction is V2-only and always requires a wallet.
SCHEMASURE_TIMEOUT_MSPer-call request timeout in milliseconds.
SCHEMASURE_PRIVATE_KEYSecretOptional EVM key for a dedicated spending wallet. Signs x402 Base or MPP Tempo payments locally; never sent to SchemaSure.
SCHEMASURE_MAX_PRICE_USDClient-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_PROTOCOLPayment protocol: x402 (USDC on Base) or mpp (USDC.e on Tempo). Signing stays local.

Local servers need a runtime on your machine (e.g. Node.js 18+). Config file locations differ by client; see your client’s docs.

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
