- Background: MCP adoption has far outpaced the industry's ability to refine its access controls and defense mechanisms.
- Scope: Includes real-world security incidents, research blogs, penetration testing findings, or highly dangerous misconfigurations.
- Current Status: Almost every week, new analysis reports reveal that certain MCP servers are inadvertently granted far more system access than intended.
