Docker PM: The Intern Installed an MCP Server, Then This Happened

Securing AI agents requires addressing the risks of unauthorized Model Context Protocol (MCP) servers and unintended autonomous actions. Real-world "horror stories," such as interns leaking sensitive data through unvetted tools or agents deleting critical work-in-progress code, highlight the urgent need for robust governance. A three-pillar defense strategy involves implementing an MCP gateway to act as a control layer for curated catalogs, authentication, and audit logging. Complementing this, Docker sandboxes provide OS-level isolation using containers and micro VMs to restrict file system and network access, ensuring security is enforced outside the agent's logic. Effective solutions must integrate seamlessly with existing identity providers, secret managers, and observability stacks across local or multi-cloud environments. By answering who is accessing which tools and monitoring the data flow, organizations can close the gap between permitted actions and intended outcomes.
