As developers use AI agents to generate Terraform configurations, ensuring compliance with internal policies becomes a critical challenge. This talk presents a new approach: Integrating an MCP (Model Context Protocol) server that connects AI agents with existing OPA (Open Policy Agent) policies. By querying these policies, the server extracts real-time constraints, such as allowed instance types, required tags or open ports, and feeds them back into the generation prompt. This allows developers to request infrastructure in natural language (“I need a server on AWS”) and receive compliant Terraform code by default. The session includes a prototype demo and explores how this pattern bridges policy, AI and Infrastructure as Code inside modern developer workflows.
