Unleashing Developer Creativity through Model Context Protocols
The discourse surrounding the infrastructure of the Model Context Protocol (MCP) predominantly revolves around the governance of numerous AI tools and the monitoring of MCP servers. While these are foundational questions, they somewhat limit the broader possibilities. A more expansive inquiry would be: how can we leverage MCP to foster developer creativity from a reliable foundation?
From Static Catalogs to Dynamic Playgrounds
The initial question often results in a static compilation of controlled and curated resources. However, a more progressive approach envisions an AI environment where agents and developers can interact and learn collaboratively. Imagine transforming private catalogs of MCP servers into dynamic playlists that promote the mixing, reshaping, and numerous combinations of tool calls. This transformation requires viewing MCP catalogs as OCI artifacts rather than mere databases.
In the realm of cloud-native computing, feedback loops have transformed infrastructure into code, made deployments declarative, and turned operational knowledge into shareable artifacts. MCP catalogs need to embrace a similar evolution. OCI artifacts, with immutable versioning and container-native workflows, offer a model that harmonizes trust with creative growth.
Building Trust and Learning Boundaries
Consider the evolution from iTunes, which served as a store, to Spotify, which added algorithmic discovery, playlist sharing, and evolving taste profiles. Similarly, private MCP catalogs could enable a similar advancement. Currently, they serve as curated and verified collections, but in the future, they could form the foundation for self-improving discovery systems.
At present, thousands of MCP servers are dispersed across platforms like GitHub, registries, and forums. Community registries such as mcp.so, Smithery, Glama, and PulseMCP are striving to organize this ecosystem, but issues of provenance and quality remain. Private catalogs with stricter access controls can offer centralized discovery, enhanced security through vetted servers, and insights into the tools developers actually utilize. Organizations can create curated subsets of approved servers, integrate proprietary internal servers, and selectively draw from community registries, effectively addressing the "phone book" problem.
Transforming Output into Input
The real potential emerges when the work done by agents results in shareable artifacts and automatic organizational learning. For instance, an agent tackling a complex issue like customer churn analysis across multiple data sources could generate a profile encapsulating the tools, API keys, sequence of operations, and documentation of successful strategies. This profile could then be stored as an OCI artifact in a registry.
Subsequently, another team facing a similar issue could use this profile as a starting point, adapt it, and then enhance it. For instance, a customer success team could create a churn profile using data warehouse connectors, visualization tools, and notification servers. The sales team might then import this profile, add CRM connectors, and use it to strategize renewals, eventually publishing their enhanced version back to the catalog. Through this process, teams move from rebuilding identical solutions to reusing or remixing existing ones, capturing, sharing, and refining knowledge.
Advantages of OCI in MCP
Treating catalogs as immutable OCI artifacts allows agents to pin to specific versions or profiles. For instance, production agents might use catalog version 2.3, while QA might use version 2.4, preventing unwanted drift. Without this approach, an agent could fail unexpectedly if a crucial database connector was silently updated with breaking changes. This setup also simplifies audit trails, allowing for clear proof of which tools were available during any particular incident. OCI-based catalogs are the only approach that treats catalogs and agents as first-class infrastructure, fully manageable with GitOps tools.
OCI with containers offers two significant benefits for MCP. Firstly, containers provide hermetic but customizable security boundaries rich in context. An MCP server operates within a sandboxed container with explicit network policies, filesystem isolation, and resource limits. Secrets are injected through standard mechanisms, with no credentials in prompts, crucial if MCP servers execute arbitrary code or access the filesystem.
Secondly, containers and the associated OCI versioning seamlessly integrate reusable governance tools, aligning with other governance tools in the general container stack and workflow. Because catalogs are OCI artifacts, image scanning works identically. Signing and provenance are managed using Cosign on catalogs, akin to images. Registries like Harbor and Artifactory already have sophisticated access controls. Policy enforcement through OPA applies to catalog usage just as it does to container deployments. Thus, FedRAMP-approved container registries can handle MCP catalogs as well, without the security team needing to learn new tools.
Evolving from Static to Intelligent Platforms
Organizations have the potential to evolve into dynamic discovery systems within trust boundaries. An MCP gateway permits agents to query the catalog at runtime, select the appropriate tool, and instantiate only the necessary components. With Docker’s Dynamic MCPs in the MCP Gateway, agents can call built-in tools like mcp-find and mcp-add to search curated catalogs, pull and start new MCP servers on demand, and discard them when they’re no longer needed. This prevents the hard-coding of tool lists and configurations. Dynamic MCPs ensure that unused tools remain out of the model’s context, reduce token bloat, and allow agents to assemble just-in-time workflows from a vast pool of MCP servers.
The longer-term vision extends even further. The gateway captures semantic intelligence about how users interact with MCPs, learns which tools work well together, and suggests relevant servers based on past problem-solving experiences. Teams learn from and contribute to this feedback loop. Private catalog users discover new MCPs, creatively mix them, and develop novel methodologies, inspired by their insights and suggestions from the MCP gateway. This process also provides live reinforcement learning, imparting wisdom and context to the system, benefiting all users of the gateway. This represents organizational memory as infrastructure, emerging from the actual work of agents that blends human and machine intelligence in limitless ways.
Conclusion: A Secure Foundation for AI Innovation
The container-native approach using private catalogs, dynamic MCP for runtime discovery, profiles as OCI artifacts, and sandboxed execution constructs a composable, secure foundation for a future AI playground. How can we unleash MCP to drive developer creativity from a trusted foundation? By treating MCP like containers but granting it the privileges that AI deserves as agentic, intelligent systems. Private MCP catalogs, enhanced with semantic intelligence and context understanding, built on OCI versioned infrastructure, and operating in secure agent sandboxes, represent the first step toward this vision.
