Why it matters
MCP servers are becoming a practical bridge between AI agents and external systems, so defenders must recognize that well-known AppSec bugs now become reachable through AI-controlled tool calls.
A comparative AppSec assessment examines how classic vulnerability classes—path traversal, command injection, and server-side request forgery (SSRF)—manifest in Model Context Protocol (MCP) servers that expose tools, files, and APIs to AI applications. The piece argues MCP does not create new categories of software failure but changes the context by placing familiar vulnerable sinks behind an AI-mediated execution path involving models, clients, and tool definitions.
