Megent launches a policy enforcement layer that intercepts AI agent tool calls before execution to control what agents can access and do.

Megent catches every tool call an AI agent makes before it executes, checks it against a policy file, and returns ALLOW, STOP_TOOL, or HUMAN_IN_THE_LOOP decisions in under a millisecond.

The system includes sensitive-data detection that identifies risky fields when agents call data, an identity layer using signed JWT passports to verify agent trust levels, and budget-limiting policies to set spend caps by agent, workflow, or day.

Teams can wrap third-party agents they did not write—vendor plugins, marketplace agents, open-source bots—and enforce their own rules regardless of what's inside the black box, addressing supply chain risk when deploying agents with unknown behavior.
