AI agents call mcpretentious-screenshot to retrieve information from MCPretentious without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

However, severity is elevated to medium rather than low because: (1) it provides visibility into potentially sensitive terminal content (credentials, API keys, private data may be visible on screen), and (2) it is part of a terminal control system where…
