MCP client configuration

Use an MCP client that supports Streamable HTTP and x402 MCP payments. Add the primary endpoint above, call catalog_service_info to inspect the current terms, and then call check_shopify_catalog_csv with csv_text. The SSE endpoint remains available for older clients.

An unpaid call returns an x402 payment requirement containing the exact amount, Base network, USDC asset, receiving address, and Bazaar discovery metadata. The client signs the payment authorization; this repository contains no wallet secret or signing key.
