TL;DR: Model Context Protocol standardises how AI applications connect to enterprise tools, but BigID’s analysis shows that the protocol also creates a new security boundary where excessive permissions, prompt injection, token misuse, and malicious servers can turn agent actions into real business risk. Treating MCP as part of identity, data, and AI governance is now essential.
Editorial analysis by NHI Mgmt Group, based on content published by BigID: “MCP Security: Risks, Architecture, and Best Practices”.
Key questions
A: Without governance, teams lose visibility into which agents are using which tools, whether shadow IT is present, and what actions were taken.
Q: Why do AI agents and MCP integrations increase IAM risk?
A: AI agents and MCP integrations increase IAM risk because they multiply the number of tool connections, service accounts, and tokens that can carry execution authority.
Q: What are the signs that an MCP deployment is being used unsafely by agents or downstream users?
A: Warning signs include unknown fields being accepted, risky write operations proceeding without approval, repeated retries creating duplicate actions, and tool calls reaching unexpected hosts or regions.
Practitioner guidance
- Define an approved MCP server inventory List every host, server, tool, and connected identity that can participate in production AI workflows, then assign an owner and review cadence for each.
- Separate read and write capabilities Split retrieval, query, and modification functions so agents do not inherit broad combined access that can turn a harmless query into an operational change.
- Bind credentials to audience and service Use short-lived, audience-bound tokens and separate downstream credentials so a server cannot reuse one token across multiple services or scopes.
Bottom line: MCP shifts AI connectors from simple integrations into governed access paths that can read, modify, and trigger enterprise actions.

MCP security is really identity governance for AI-driven action. Once agents can discover tools, request context, and invoke enterprise systems, the protocol becomes an access model, not just an integration standard. That means privilege design, entitlement scope, and approval boundaries matter as much as transport controls. Practitioners should treat MCP as part of the organisation's IAM and data governance fabric.
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: How should identity teams govern MCP compared with conventional API integrations?
A: MCP needs runtime identity governance because it is not just a transport layer for requests. Conventional integrations can often be reviewed at design time, but agentic workflows require control over context, delegated authority, and the lifecycle of the credentials that power each tool path.
