TL;DR: MCP servers standardise how LLMs reach tools and data, but they also widen the identity and authorisation surface by letting AI assistants trigger deployments, query databases, and update documentation across GitHub, Vercel, Supabase, Notion, Box, and Firebase, according to Descope. The practical issue is not connectivity, but whether access scopes, session controls, and auditability keep pace with cross-tool AI workflows.
Editorial analysis by NHI Mgmt Group, based on content published by Descope: “The 7 Best MCP Servers for Developers”.
Key questions
Q: What breaks when MCP servers are exposed without identity controls?
A: Without identity controls, anyone with a link, key, or copied credential can reach tools and data outside policy.
Q: Why do AI tool chains increase authorisation risk in development environments?
A: Because the assistant can combine small, legitimate permissions into a larger delegated act.
Q: How should teams implement session elevation for MCP-based workflows?
A: Use read-only sessions by default, then require explicit approval for writes that affect users, flows, deployments, or records.
Practitioner guidance
- Govern each MCP server as a discrete access surface Inventory every server, its tools, and its exposed resources before enabling it in the IDE.
- Split read and write permissions by session state Start all AI-assisted sessions in read-only mode and require explicit elevation for any action that changes users, flows, deployments, data, or documentation.
- Review chained workflows as one delegated act Assess combinations such as code review plus deployment, or documentation updates plus database queries, as a single authority chain.
Bottom line: MCP servers reduce integration friction, but they also turn AI-assisted development into a delegated identity problem across multiple systems.

MCP has turned tool integration into an identity governance problem. The protocol’s value lies in standardising how models reach external systems, but that also standardises how privilege can be delegated across many services at once. Once an AI assistant can touch code, data, and deployment from the same workflow, IAM cannot stay app-specific. Practitioners should treat MCP as a control-plane issue, not an integration convenience.
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 connectors like ordinary integrations?
A: No. MCP connectors often carry delegated access into multiple tools and data stores, which makes them part of the identity control plane. They should be registered, scoped, monitored, and offboarded like any other privileged machine identity, otherwise a compromise in one connector can expand into broader system access.
