With the rapid adoption of Model Context Protocol (MCP), security risks are becoming increasingly prominent. A developer posted on Reddit asking the community to share their MCP security "horror stories" from practice.
- 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.
