PromptArmor breaks down how WebMCP works and its security risks
What happened
On October 6, PromptArmor published an analysis of how WebMCP works and the security risks around it, describing how websites offer tools to AI agents through WebMCP. The report says this differs from traditional MCP integration and from agents clicking through a browser to get things done: WebMCP tools are supplied by the webpage and run through site code inside a session where the user is already logged in. The analysis also lays out the governance, prompt injection and web security risks tied to that setup, focused on website-provided tools and how they execute in a logged-in session.
