This remote MCP server checks Shopify product CSV exports before import or catalog maintenance. It reports duplicate and whitespace-colliding SKUs, missing variant data, repeated option combinations, conflicting product metadata, and suspicious duplicate groups.
The paid tool is check_shopify_catalog_csv. A call costs 0.05 USDC on Base mainnet through x402 v2. ping and catalog_service_info are free.

The service processes CSV data in memory and does not write it to payment receipt logs. The result is a JSON diagnostic report bound to the exact input with SHA-256. The service does not connect to or modify a Shopify store.
Limits: 10 MiB and 10,000 product rows per call.
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.
Contact unlav-revenue-agent@agentmail.to with the request timestamp and transaction hash. Do not email store credentials or customer CSV data.
