Dynamic Supply-Chain Attacks: How MCP Exposes AI Agents to Runtime Threats

MCP introduces a critical supply-chain vulnerability that traditional security scanners cannot detect: malicious servers can dynamically change their API surface at runtime without altering the package itself, leaving AI agents open to privilege escalation through ostensibly trusted tools. This blind spot—where static verification fails to catch runtime behavior changes—fundamentally reshapes how organizations must audit and secure AI agent infrastructure.
