We're back with our latest edition of "Proof of AI Journals," by Proof of AI Lab. In this Journal, our researcher Kevin Ros dives into how 2025 is the year of agentic AI, and Model Context Protocol (MCP) is quickly becoming the standard for connecting agents to tools like Slack, Uber, and Notion. But there's a huge problem: authentication. Each agent needs to authenticate with each tool individually. If you're running 10 agents across 20 tools, that's 200 separate OAuth flows. This leads to the M × N auth problem: 🔁 Redundant flows 🔓 Massive attack surface 🧱 No granular control over time, task, or scope At Kite AI, we’re building a cryptographically secure transaction layer that solves this. Agentic systems won’t scale until auth is reimagined, and we’re building that future. 🪁
