Get clipboard contents
AI agents call execute_clipboard to retrieve information from Cobalt Strike MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool reads clipboard data from a compromised system. While 'Get' indicates a read operation with no direct side effects, the context (Cobalt Strike beacon control on a target system) makes this a significant privacy/security concern — clipboard contents may contain passwords, sensitive data, or credentials.
