Most of them run on all-or-nothing API keys. This is where the web was before OAuth 2.0 — and it's exactly as dangerous as it sounds. The Problem When you connect an AI agent to a real service — Stripe, Gmail, Salesforce — you typically give it an API key with full access. The agent can do anything the key allows. There's no scoping ("read emails but don't send"), no audit trail ("what did the agent do?"), and no revocation ("stop this agent NOW"). This was fine when agents were demos. It's not fine when they're in production. What We Need The web solved this 15 years ago with OAuth 2.0: users grant scoped, revocable access to applications. But OAuth was designed for human users clicking consent buttons.
