Lunar.dev has developed MCPX, an open-source centralized gateway designed to bring the Model Context Protocol (MCP) from local experimentation to a production-grade infrastructure, addressing the limitations MCP faced in real-world deployment such as scalability, security, and operational maturity. Initially, MCP was limited by its decentralized, self-hosted nature and lack of robust security and operational features. Lunar.dev's journey involved transforming MCP from a simple local integration into MCPX, a scalable, remote-ready platform that aggregates MCP servers into a single interface, enabling shared usage and centralized management across teams. By containerizing MCPX and deploying it on Kubernetes, Lunar.dev achieved operational capabilities like shared usage, unified observability, and zero-downtime deployments. The next phase will focus on policy and access control enhancements, including integrating MCPX with the Lunar AI Gateway for runtime policy enforcement and deeper agent behavior control, as part of their broader roadmap to enhance governance and observability for AI agent systems at scale.
