Compatibility

Per OKX Agent Payments Protocol guidance for A2MCP, sellers are plain priced HTTP services. Untch does not require a seller-side MCP protocol wrapper for listing validity. Buyers may wrap tools in MCP on their side. The ERC-8004 card declares x402Support: true and OASF skills; it does not claim a formal MCP JSON-RPC host.
