TL;DR: MCP supply chain security is becoming a governance problem because compromised tool definitions, context stores, and orchestration layers can steer AI outputs or trigger unsafe actions, according to Akto. The control gap is not just code integrity but lifecycle oversight across the MCP chain.
Editorial analysis by NHI Mgmt Group, based on content published by Akto: “MCP Supply Chain Security: Why It Matters Now”.
By the numbers:
- In 2024, over 183,000 customers were impacted by supply chain cyberattacks.
Key questions
Q: What breaks when MCP tool definitions change without re-approval?
A: What breaks is the assumption that a previously trusted tool still behaves the same way.
Q: Why do compromised MCP components create governance risk for AI systems?
A: Because MCP components can change what the model sees, which tools it can call, and what actions it can trigger.
Q: What are the signs that MCP context poisoning is happening?
A: Look for repeated policy violations, unusual tool choices, inconsistent outputs from the same task, or context that appears to survive longer than expected.
Practitioner guidance
- Map the full MCP trust chain Inventory tool definitions, connectors, context stores, update channels, and orchestration services that can influence agent behaviour.
- Apply provenance checks to context inputs Verify the origin and integrity of documents, metadata, and retrieved context before the model can reuse them in later sessions.
- Pin and audit tool versions Treat tool definition changes and package updates as privileged events.
Bottom line: MCP supply chain security should be treated as governance over the AI decision surface, because compromised tool and context layers can change model behaviour without touching the base model.

MCP supply chain security is now an AI governance problem, not just a software integrity problem. The article is right to frame tool definitions, context stores, and orchestration layers as control points that can alter the behaviour of the system itself. Once AI systems consume external inputs continuously, security has to govern the lifecycle of those inputs, not only the code that delivers them. Practitioners should treat MCP trust boundaries as part of AI governance.
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 organisations govern agentic AI supply chains across MCP workflows?
A: Assign ownership for every upstream component that can influence agent behaviour, then require approval, traceability, and monitoring for changes to those components. The goal is to manage delegated trust, not just application access. Governance should cover provenance, update control, runtime isolation, and offboarding of untrusted or stale integrations.
