Why it matters
MCP servers concentrate authenticated tokens for many systems, so defenders must track what data flows through agent connections, not just harden authentication, since a stolen token used via MCP mimics ordinary API traffic.
Forcepoint's blog argues that MCP security discussions overlook data exposure risks, noting that a single compromised MCP server can expose every credentialed system it connects to (Salesforce, M365, Slack, code repos, finance DBs). It cites 30+ CVEs filed against MCP servers between January and February 2026, command-injection prevalence, and the postmark-mcp package that silently added a hidden recipient to exfiltrate copies of AI-agent emails.
