In this episode of the Security Repo Podcast, we welcome Srajan Gupta, a security engineer exploring the evolving security implications of Model Context Protocol (MCP) servers. Shrojan breaks down how MCPs act as AI connectors to external systems and the alarming rise in attack surfaces, including tool squatting and indirect prompt injections. The conversation dives into emerging threats, authorization challenges, and how securing MCPs mirrors early API and cloud security lessons.Srajan Gupta is a security engineer and builder focused on uncovering how systems fail — not just through vulnerabilities, but through the architecture itself. With a background in application security, platform engineering, and threat modeling, Srajan works at the intersection of usability and risk, helping teams identify and address design-level security flaws before they become incidents.Srajan is passionate about building practical security tools, automating guardrails, and making threat modeling an everyday engineering skill.Blog - https://srajangupta.substack.com/BSides LV talk - https://www.youtube.com/watch?v=Wld0VVRMN4c&t=21977shttps://www.linkedin.com/in/srajan-gupta/Their research often explores trust boundaries, secure defaults, and the hidden assumptions baked into the applications and infrastructure. They are especially interested in how attackers exploit the gray areas between platforms, automation, and access controls — and how defenders can close those gaps without slowing down delivery.
