Get YARA rules available for backup scanning.
AI agents call GetYaraRules to retrieve information from Veeam VBR v13 MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of YARA rule metadata or configuration within the Veeam backup system. It has no side effects—it does not create, modify, execute, delete, or move any data. The blast radius of misuse is minimal since an agent could only retrieve information about available rules, which poses no risk to the infrastructure or data.
From the tool's definition GetYaraRules retrieves or queries YARA rules available for backup scanning. The verb 'Get' and the passive retrieval nature indicate this tool reads existing configuration data without modifying, executing, or deleting anything.
