Using MCP to Control Your Feature Flags

The Model Context Protocol (MCP) is a framework that facilitates the integration of AI applications with external systems, offering promising capabilities such as feature flag control directly from an IDE. Despite its growing adoption and impressive download statistics, MCP presents significant security risks if used for autonomous feature management in production environments. The protocol's vulnerabilities, notably tool poisoning and high attack success rates, underscore the need for strict control measures, such as OAuth 2.1 authentication and human-in-the-loop approval processes, to prevent unauthorized changes. MCP's primary value lies in managing tool discovery and administration workflows, while standards like OpenFeature govern runtime evaluation. Instead of relying on AI for production-level decisions, teams should leverage MCP tools for reducing technical debt by identifying and removing stale feature flags. This approach emphasizes the importance of structured workflows, where AI assists in cleanup and governance tasks under strict supervision, ensuring secure and efficient continuous delivery without exposing infrastructure to critical vulnerabilities.
