Submit a feature request ($1 anti-spam fee, charged to the prepaid balance when funded). Auth required. Payment flow: call once without x_payment — a 402 reply lists the exact EIP-3009 requirements (amount, USDC asset, recipient, EIP-712 domain). Sign a transferWithAuthorization for them outside MCP (this server cannot sign), then call again with x_payment set to the base64 of {x402Version:1, scheme:'exact', network, payload:{signature, authorization}}.
