Full Analysis

MEDIUM W011: Third-party content exposure detected (indirect prompt injection risk).

  • Third-party content exposure detected (low risk: 0.10). The required workflow uses CoinMarketCap APIs and an MCP server which return data from external cryptocurrency markets and user-submitted search queries/tokens.

MEDIUM W009: Direct money access capability detected (payment gateways, crypto, banking).

  • Direct money access detected (high risk: 1.00). The skill integrates the x402 protocol, which involves automatic stablecoin payments over HTTP using on-chain USDC on Base. It configures EVM private keys and payment signing schemes (ExactEvmScheme, toClientEvmSigner, private key handling via viem) specifically to execute microtransactions ($0.01 per API request) directly from a wallet, which falls under crypto/blockchain wallet and transaction execution capabilities.
