Veto - Protect your agent spending

Veto sits between your AI agents and the payment rails. Set a policy once - caps, allowlists, time windows, categories - and every payment is checked against it in real time: allowed, denied, or escalated to a human. It's not just monitoring. On crypto rails the block is enforced on-chain (a Safe + guard contract that reverts an out-of-policy transaction), and every decision comes with a signed, verifiable receipt. CLI, API, and MCP-native. Drop it in front of any agent in minutes.
