BuildingAPOA — Open Source authorization for AI agents

About

Electrical engineer by training, product builder by craft, founder by instinct.

The question I keep coming back to lately: how an agent gets authority to act on someone's behalf, and how that authority stays scoped, logged, and revocable. Most agent demos end with an API key and hope. That's the gap APOA is trying to close, as an open-source layer on top of MCP.

Notes

May 2026

The Burrito Problem (a solution)

Kyle Kingsbury joked an AI agent might get talked into a $950 grandmother burrito by El Farolito's chatbot. I think he was being optimistic. So I built a working prototype where the boundaries live in a signed token between the LLM and the execution layer, not in the prompt.

Two OpenClaw agents negotiate a YC SAFE with Agentic Power of Attorney

I gave an AI agent access to act on my behalf a few months ago. Within ten minutes I was scared of it. Not because it did anything wrong. Because I had no way to guarantee it wouldn't. The entire trust model was a system prompt and vibes. I built APOA as my take on a solution.
