MCP Beyond APIs: The New Security Contract Introduced by Agents
drhyrum · x · 2026-08-05
The article explores the new challenges in API security arising from the adoption of MCP (Model Context Protocol) and AI agents. The author notes that while MCP may appear to be just another JSON-over-transport API format, it introduces a new audience, universality, and an implied contract.
Traditional API security reviews often rely on existing experience, but agents straddle security boundaries and alter the original implied API contract. The article emphasizes that beyond the classic "confused deputy problem," the involvement of agents fundamentally changes the logic and expectations of API calls, meaning the security landscape is still very new and full of unknowns.
