Could you build this?
Partial The MCP API directory is buildable, but credential-proxying, x402 USDC payment settlement, and onchain ERC-8004 identity lookups need security-sensitive and blockchain-specific engineering that vibe coding alone may not get right.
What it would actually take: The stack would be an MCP server and registry, a gateway that proxies provider APIs while keeping upstream keys server-side, and an x402 payment flow that gates calls and settles in USDC on Arc. The hard parts are secure key custody, correct payment verification and refunds, and reliable reads of ERC-8004 registry contracts. This requires backend security expertise and familiarity with payment and smart-contract tooling.
