webMCP Isn't the New Accessibility Layer—It's a New Attack Surface: A governance-grade reframing of a playful demo
A recent article reframes webMCP, a tool designed to expose structured website actions, not as an accessibility layer but as a significant new attack surface. The author argues that unlike accessibility metadata, webMCP's actions are executable functions, posing risks such as unbounded action exposure, agent overreach, and protocol brittleness. The integration of webMCP into browsers exacerbates these issues, potentially leading to session hijacking and cross-site orchestration, necessitating robust authorization, auditing, and safety measures before widespread adoption.
