Get recovery capability of a time machine
AI agents call get_time_machine_capability to retrieve information from NDB MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries information about a time machine's recovery capabilities without modifying, executing, or deleting anything. It is a pure read operation that returns metadata about database backup/recovery features. The low severity reflects minimal risk from misuse—exposure of recovery capability information does not directly compromise systems or data.
