AgentAdmit is the authorization layer for the agent economy. It gives people a safe way to let an AI agent access their account: the user grants the agent specific, time-limited access, the credential is delivered to the user instead of flowing to the agent through an automated channel, and every grant is scoped, revocable, and auditable.
Why it exists
Most AI agent access today runs on API keys, OAuth redirects, or environment variables. Those channels move a credential with no human at the point of delivery, so a prompt injection or a misconfiguration can intercept it. AgentAdmit removes that automated path. The credential goes to the human, the human hands it to their agent, and the authorization decision happens outside the agent’s execution context, so an injected instruction has no way to escalate access.
What this blog is for
This is where we work through the real questions builders are asking: how to let an agent into a user account without handing over the keys, what user-mediated authorization means, how MCP security and prompt injection change the threat model, and how to keep the human in control. Practical and specific.
