As organisations accelerate their adoption of AI technologies, a new category of externally reachable services is emerging — including Model Context Protocol (MCP) servers. These services enable powerful automation and integration across your environment, but they can also introduce unmonitored, internet‑facing entry points that traditional security tools struggle to detect.
These blind spots matter. If MCP services are deployed without visibility or governance, they can expose sensitive operations, allow over‑privileged automation, or introduce pathways that attackers can exploit long before anyone notices.
To help you stay ahead of this evolving risk, NCC Group’s Managed External Attack Surface Management (eASM) service now includes continuous discovery, classification, and exposure insight for MCP services. This enhancement is designed to give you the clarity and control you need as AI‑driven capabilities scale across your organisation.
What does this mean for you?
Find the AI‑related assets you didn’t know you had
AI services often appear across your digital footprint in unexpected places, spun up by teams experimenting, vendors, pilots, or automated deployment workflows. With integrated MCP discovery, you gain immediate visibility of any MCP servers exposed to the public internet, including those outside approved patterns or missed by existing inventories.
Bring AI services into a governed inventory
Newly identified MCP services are automatically added to your external asset inventory, allowing you to manage them like any other internet‑facing asset. This ensures nothing remains hidden and everything is subject to unified monitoring and governance.
Understand the real risk behind each service
Not all MCP services present equal risk. You’ll receive clear context around:
• How each service is reachable
• What operations it exposes
• Where controls or access paths may introduce vulnerability
This enables risk‑based prioritisation, helping you focus effort where it matters most.
Actionable guidance integrated into your existing workflows
MCP exposure data seamlessly feeds into your established eASM workflows, supported by NCC Group analysts who interpret the findings and provide next‑step recommendations to inform intelligent action. The result? Clear, human‑validated direction, rather than another stream of raw technical data.
Why does this matter now?
Industry analysis shows that AI is reshaping the attack surface faster than governance models can adapt. MCP and similar integration layers can unintentionally expose powerful capabilities externally, creating complex, fast‑moving challenges for security teams.
Independent experts highlight the risk of:
• Sensitive data exposure
• Unauthorised automation
• Privilege escalation
• Governance bypasses
This expanded visibility is essential to avoid AI‑related blind spots becoming tomorrow’s breach pathways.
How does the technology work?
The capability is powered by leading external attack surface discovery technology that continuously scans the internet for exposed assets associated with your organisation.
When it identifies externally reachable MCP services, it enriches them with contextual risk insights and feeds them into your managed workflows, giving you actionable visibility backed by expert human analysis.
The benefits?
• No more hidden AI services — MCP assets become visible and governed
• Stronger, faster decision‑making — exposure context highlights real risk
• Consistent governance — AI‑related services align with your broader security controls
• Expert support — NCC Group analysts help interpret findings and guide remediation
The bottom line
As AI services proliferate across your organisation, your attack surface is growing in new and unexpected ways. This enhancement ensures you maintain full visibility and control, so you can innovate with AI confidently, without introducing unmanaged risk.
