AgentShield stops AI agents from draining wallets
AgentShield is an open-source, locally hosted FastAPI gateway and Redis vault designed to physically block AI agents from overspending. By intercepting tool calls and requiring pre-approved vouchers for HTTP 402 Machine Payments, it provides a "budget shield" that prevents expensive autonomous loops.
// ANALYSIS
AgentShield solves the "infinite loop" financial risk by moving budget enforcement from soft system prompts to hardened local infrastructure.
- –Uses atomic Redis Lua scripts to prevent replay attacks and ensure double-spending protection during payment handshakes
- –Employs a two-plane architecture separating the LangGraph "Brain" from a high-speed FastAPI "Gateway" to minimize latency
- –Integrates with the Tempo network (USDC.e) to settle real-value transactions via the Machine Payment Protocol
- –Local-first design keeps sensitive budget controls and API keys within the user's controlled environment
- –Addresses a critical bottleneck for agentic commerce: the fear of unconstrained financial liability from autonomous agents
