As enterprise AI agent adoption scales, the absence of centralized, organization-level tool infrastructure is producing compounding costs. When adoption is built around optimizing for deployment speed, enterprises expose themselves to a combination of risks: duplicated engineering effort, security exposure, and operational opacity.

Every enterprise needs its own shared tool registry, one that reflects its specific regulatory environment, security posture, and operational conventions. To be clear, this is not an argument for a public package manager, something like npm, PyPI, or Maven. The infrastructure each enterprise needs is internal; scoped to its own teams, its own data, its own policies, its own domain. Trying to expand the scope beyond the confines of individual organizations would be premature standardization in a fast-moving, nascent space.

A shared enterprise tool registry is not an optimization or a nice-to-have. It is foundational infrastructure as agent deployments scale beyond early experiments. The case for it rests on two pillars: reducing coordination cost and enabling risk management, both for the humans building with agents and for the agents themselves.

AI agents depend on tools that retrieve data, write records, trigger workflows, and call external APIs. According to McKinsey, in most large organizations, these tools are built by individual teams in an ad hoc fashion: undocumented, ungoverned, and invisible to the rest of the organization. This pattern is familiar to most engineering leaders, and the fragmentation it creates compounds with every new agent deployment. Teams rebuild what already exists elsewhere, security reviews miss tools that were never registered, and when something breaks, no one has a complete picture of what is running or why.

A coordination failure at infrastructure scale

The software industry solved an analogous problem decades ago with package managers. Centralized registries gave teams a way to discover, depend on, and govern shared code. The learning was clear: preventing duplication and inconsistency is an infrastructure problem, not a discipline problem.

The agent era presents the same problem in a new domain. When Kong launched its enterprise MCP Registry in February 2026, they explicitly called out the problems of manual MCP configuration, hardcoded and managed tool isolation across teams, fragmented integrations, and limited organization visibility.

Fragmented tool development is not a consequence of poor engineering practice. Rather, it is the predictable outcome of asking teams to solve an infrastructure problem at the application layer.

The visibility problem

Gravitee's The State of AI Agent Security 2026 survey quantifies what happens when agent tooling is invisible to the people responsible for securing it. The survey found that only 14.4% of teams with agents beyond the planning phase have full security approval, and 88% of organizations had an agent-related security incident this year. Bad practices like shared API keys are endemic, with only 22% of organizations treating agents as independent identities. This governance gap transforms agents from productivity boosters into high-velocity liabilities capable of executing unauthorized actions or leaking sensitive data before a human can even intervene.

The story is clear: adoption is outpacing governance, and in a race for speed, old lessons are having to be retaught. The majority of deployed agents (and the MCP servers powering them!) are operating without any security sign-off. This is not primarily a resourcing failure, and it is not something a registry alone solves. Security teams cannot review what they cannot discover, and without a registry, discovery is manual, incomplete, and stale. A registry does not make tools inherently secure; rather, it makes security work possible by ensuring tools exist not as transitory, ad hoc shims, but rather as inventoried artifacts that audits and policy can attach to.

It is worth revisiting public package managers here. These registries have not been able to eliminate a number of security problems, issues such as typosquatting, malicious packages, and dependency confusion, showing clearly that centralization alone is not a security solution. But they also show the converse: a registry is a precondition for security. Numerous community responses to breaches in these ecosystems demonstrate the power centralization provides. Centralization does not guarantee security, but decentralization forfeits the means to coordinate it.

Governance requires shared context

The default posture in most agent deployments is permissive: tools are available unless explicitly blocked. AgilityFeat's analysis of enterprise AI guardrails identifies the structural risk this creates, since an architecture not built on deny-by-default increases risk and creates upkeep costs.

Allow-by-default, replicated across dozens of independent agent deployments, produces an attack surface that scales with adoption. Inverting this requires a coordination point, a shared, organization-wide context. The registry itself isn’t a governance layer, but it is what makes governance possible. When every tool an agent can use is registered with ownership, version, and review status, the governance layer has something concrete to enforce against. Without that context, policy has to be reimplemented by every consuming team, and consistency becomes impossible. 

Frontegg's framework for AI agent governance describes what that policy layer looks like operationally: agent actions mapped to explicit, granular guardrails that define the operational boundaries for what any agent can attempt or execute. These guardrails live outside the registry, but they depend on it. A guardrail that references a tool the security team has never heard of cannot be written in the first place.

What a production-grade tool catalog requires

A mature enterprise tool registry has two core functions, discovery and versioning, and serves as the foundation for two others: certification metadata and access control. Think of it as an Internal Developer Portal (IDP) built for the agent era, solving the same coordination problem that IDPs solved for service teams, but one layer up.

Discovery allows any team building an agent to search for existing tools before writing new ones. With ownership metadata, version history, and usage metrics centralized, duplication is reduced not through mandate but through reduced friction. A well-designed catalog goes further than a flat list: tools should be grouped hierarchically by functional domain so that both humans and agents can find relevant capabilities quickly. 

Versioning closes a gap that neither discovery nor access controls address: when agent behavior changes, why did it change? A tool registry that tracks versions gives enterprises the visibility to answer that question. Was it the model? A tool prompt update? An underlying API change? Without proper versioning, finding the answer goes from a simple diff comparison to a time-consuming, manual investigation.

Certification status (things like security approval, API contract validation, PII handling checks) is metadata that the registry surfaces, not a boundary that the registry itself enforces. The actual review work happens through the security organization’s existing tooling. The registry’s contribution is making the result of that review visible at the moment a team is deciding whether to adopt a tool, ensuring the review actually informs the decision it was meant to inform.

Access control works the same way. A policy layer enforces authorization scoped to agent identity, team, environment, and action type, reading from the registry to know what tools exist and who owns them. The registry’s centralization lets access control be applied consistently, rather than forcing each team to come up with something bespoke.

None of this is achievable when each team maintains its own isolated tooling stack. Platform teams already understand why IDPs exist. The value of the paradigm in the agent context is no different.

The compounding cost of inaction

The cost of inaction is direct, not merely operational and security-related. Without a searchable, well-organized catalog of tools, teams continually reinvent the wheel, since it is easier to generate a tool than to find one that already exists. Duplication means redundancy and technical debt. A registry, by making tools discoverable and reusable, converts that redundant spend into capacity for actual work.

For platform engineering teams, the trajectory is clear. Agent adoption is increasing, tool duplication is increasing with it, and the shims that worked at small scale will not hold as the number of agents and tools grows. The security exposure documented in the Gravitee survey will widen, not narrow, without structural intervention.

The organizations that build centralized tool infrastructure now will be able to onboard new agents quickly, govern them consistently, and audit them when something goes wrong. Those that defer will rediscover, the hard way, what platform teams learned a decade ago: coordination problems do not resolve themselves at the application layer. They compound there.
