Agent Passport

Agent Passport이란?

Agents call APIs, spend money, and talk to other agents on your behalf. But who said they could? Agent Passport gives every AI agent a cryptographically signed token proving what it's allowed to do — scoped permissions, spend limits, time windows, and delegation chains that can only narrow, never escalate. One npm install. Three lines of code. Works with MCP, LangChain, and any agent framework.
