AgentShield

Connects Claude to blockchain security tooling for AI agents handling smart contracts. The server exposes operations to verify contract code before execution, monitor on-chain activity for anomalies, freeze suspicious transactions, and handle x402 payment flows. Reach for this when building AI agents that need to interact with DeFi protocols or manage crypto transactions with built-in safety rails. The verification and freeze capabilities are particularly relevant if you're automating contract deployments or letting an agent approve token transfers, where a security gate matters more than speed.
