TL;DR: MCP servers expand AI agent access to files, commands, APIs, and workflows, yet most are deployed from public sources without formal vetting, creating hidden supply-chain and privilege risks, according to Knostic. The governing problem is not just unsafe code, but a trust model that approves elevated runtime access before legitimacy, scope, and behavior are verified.
Editorial analysis by NHI Mgmt Group, based on content published by Knostic: “How to Vet and Monitor MCP Servers in the Enterprise”.
Key questions
Q: What breaks when MCP servers are not vetted before use?
A: When MCP servers are not vetted, the enterprise loses control over privileged tool access inside AI workflows.
Q: Why do unvetted MCP servers create more risk than normal integrations?
A: Unvetted MCP servers can inherit broad tool reach while hiding what data they read, what they transmit, and what decisions they influence.
Q: How do teams know an approved MCP server is drifting out of scope?
A: Teams know an approved MCP server is drifting out of scope when runtime behaviour changes, new permissions appear, or the server begins touching files, commands, or APIs that were not part of the original review.
Practitioner guidance
- Vet MCP server provenance before installation Confirm repository ownership, contributor history, and release integrity before any server is admitted into developer workflows or internal catalogs.
- Audit server permissions against declared purpose Map each requested file, shell, network, and API capability to a documented use case, and reject any scope that is broader than the task requires.
- Scan dependencies for tampering and typosquats Review transitive packages from registries and flag suspicious naming, hidden scripts, or unexpected network behaviour before approval.
Bottom line: MCP servers create a governance problem because they can inherit privileged access into agent workflows before their legitimacy is confirmed.

MCP server vetting is now a supply-chain control, not a developer preference: The article shows that the approval moment is the governance moment, because an MCP server can inherit privileged runtime access before anyone validates legitimacy or scope. That shifts the control problem from post-deployment detection to pre-deployment trust qualification. Practitioners should treat MCP server approval as a security decision with identity impact, not a convenience choice.
A few things that frame the scale:
- 24,008 unique secrets were exposed in MCP configuration files in 2025 alone, the protocol's first year of widespread adoption, according to the State of Secrets Sprawl 2026.
A question worth separating out:
Q: Should organisations treat MCP servers like ordinary plugins or like privileged identities?
A: Organisations should treat MCP servers like privileged identities, because they are not passive extensions. They execute inside trusted workflows, make file and API access possible for agents, and can widen the blast radius of a compromise if their permissions are not tightly scoped and continuously revalidated.
