SCVD General Store MCP server

This is a remote helper that lets your AI talk to scvd.store, a small online store and checking service for AI agent payments. It is handy if you work with AI agents that pay for things online and you want to check a payment door before money moves, or read a signed receipt afterward. You do not install anything and you do not need an API key.

What this MCP server does

You ask your AI something like whether a payment door is ready or whether a receipt is real. The AI sends that request to this helper, which talks to scvd.store over the internet. The store checks the endpoint or the signature and sends back a verdict. Your AI then shows you the answer in the chat, with the details and any gaps the store did not see.

Try asking your AI

• “Check if this x402 endpoint is ready to accept payments”
• “Verify this signed receipt and tell me if the signature is valid”
• “Read the latest corpus observations about x402 endpoints”
• “Buy a settlement attestation for this transaction on Base”

What it gives back to you

You get back a structured verdict or receipt, signed and dated, shown as text in your chat. For a preflight check, that means what was observed, what was not, and any gaps. For a conformance check, it means whether the signature and schema passed. For a purchase, you get a signed artifact you can verify later at a public link.
