Why you need an MCP registry, and who should own it

An MCP registry is a critical component in managing the approved servers and tools within an organization's infrastructure, ensuring that only necessary and safe tools are accessible to developers and AI agents. The text argues that while security teams are responsible for approving the list of MCP servers, maintaining the registry is a platform engineering responsibility. This involves organizing the registry by job rather than by vendor, limiting access to only the tools needed for specific tasks, which reduces the cognitive load on developers and curtails the potential for over-scoping issues. The platform team initially manages the registry, but as workflows mature, team leads may take over to tailor logical MCPs to their specific needs, ensuring that both human and machine agents can operate efficiently and safely. By focusing on job-based organization and least-privilege access, the registry can minimize risks and enhance the functionality of both developers and agents in a controlled environment, with tools like Port offering a centralized platform to manage these processes effectively.
