TL;DR: MCP deployments need registry scoping because ungoverned tool access outpaces what existing IAM processes can see, according to Stacklok. Local registries, attestation, and runtime scoping are what keep delegated access traceable and bounded.
Editorial analysis by NHI Mgmt Group, based on content published by Stacklok: “How to build a local MCP registry your security team will actually approve”.
Key questions
Q: Why do MCP deployments create risk before production rollout?
A: Because the highest-risk controls are often still being designed when teams start experimenting.
Q: What signs show that MCP access is being governed properly?
A: You should be able to see per-request logs, known server ownership, explicit approval records, and a clear mapping from user to downstream credential.
Q: What breaks when MCP servers are added without registry scoping?
A: Tool exposure expands faster than governance can track it.
Practitioner guidance
- Define the MCP approval boundary Establish a registry-based approval workflow before any MCP server is allowed into production-facing workflows.
- Bind each tool call to user identity Replace shared credentials with per-request identity tokens so the downstream system can see the user context behind each action.
- Require provenance for every server Make source attestation, image signing, vulnerability scanning, and change control part of the onboarding gate for MCP servers.
Bottom line: Ungoverned MCP deployments create a delegated-access problem that existing IAM processes cannot see clearly enough to govern.

Local MCP without a registry is a governance failure, not a tooling choice. Once AI applications can invoke internal tools from mixed sources, the enterprise loses the basic ability to inventory, approve, and revoke access paths. That is an identity control problem first and a platform problem second. The practical conclusion is that MCP must be governed as an access layer, not adopted as an informal developer convenience.
A few things that frame the scale:
- The agentic AI market is already worth $5 billion and is projected to reach $50 billion by 2030.
A question worth separating out:
Q: Should security teams approve MCP servers from public package sources without attestation?
A: No. If a server reaches internal systems, provenance becomes a security requirement, not a preference. Teams should require attestation, signing, and change control before approval, because unverified code can embed hidden access paths and credential handling behaviour.
