TL;DR: Enterprise MCP adoption is blocked less by model capability than by identity, transport, and governance gaps, according to Descope. The article argues that stdio-based servers, weak OAuth implementation, function-level permissions, and missing audit controls make production deployment harder than many teams expect.
Editorial analysis by NHI Mgmt Group, based on content published by Descope: “5 Enterprise Challenges in Deploying Remote MCP Servers”.
Key questions
Q: What breaks when MCP servers rely on local stdio transport in production?
A: You lose the operational controls that enterprises depend on, including network segmentation, centralized logging, load balancing, and consistent policy enforcement.
Q: Why do OAuth 2.1, PKCE and DCR become hard for MCP deployments?
A: They are hard because many teams have not operationalised the identity plumbing required to make MCP work with existing identity providers and runtime client registration.
Q: Where does function-level authorisation fail in enterprise MCP use?
A: It fails when organisations keep using application-level RBAC for tool actions that need narrower control.
Practitioner guidance
- Define production-ready MCP trust boundaries Separate local development servers from enterprise deployments, and require network segmentation, central logging and policy enforcement before any shared use.
- Align MCP auth flows with your identity provider Map OAuth 2.1, PKCE and dynamic client registration to existing identity provider capabilities before building custom auth logic into each server.
- Authorise tools at function level Create scopes for specific MCP tool actions, such as read, update and export, instead of granting broad application-level access.
Bottom line: Enterprise MCP is constrained by access governance, not by model capability alone.

Enterprise MCP adoption is now an identity governance problem disguised as an integration problem. The article shows that the blocker is not model connectivity but whether access can be authenticated, scoped and observed at enterprise scale. That shifts MCP from a developer convenience question into an IAM and NHI governance question. Practitioners should treat every MCP connection as a governed identity path, not a plug-in.
A few things that frame the scale:
- 96% of security operations teams report critical blind spots, most commonly in cloud infrastructure (74%) and identity and access behaviour (67%).
A question worth separating out:
Q: How should teams respond when an MCP deployment lacks audit logging and revocation?
A: They should treat the deployment as not yet production-ready for sensitive work. Without audit logging, user enumeration and selective revocation, teams cannot prove who used which tool or contain access cleanly during an incident. The result is governance debt that shows up first in audit, then in response.
