ActionGate

xyz.actiongate.api/actiongate

This is a safety middleware that sits between AI agents and blockchain wallets to validate transactions before execution. It implements the x402 protocol over MCP to let you define spending limits, approve transaction patterns, and block risky operations before your autonomous agent can drain a wallet. You'd reach for this if you're building agents that need to handle crypto payments or DeFi interactions but want a human-in-the-loop failsafe or programmatic guardrails. The streamable HTTP transport means it works with remote agents, not just local tooling. Think of it as a sanity check layer so your Claude-powered trading bot doesn't accidentally approve a six-figure swap.
