AI agents call overseerr_get_available_libraries to retrieve information from Overseerr without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves existing configuration data (server IDs and names) without modifying, executing operations, or causing any side effects. It is a straightforward read operation that queries system configuration.
From the tool's definition Tool description states it 'Get[s] the configured Sonarr (TV) and Radarr (Movie) server IDs and names from Overseerr.' The verb 'get' and the action of retrieving configuration data indicates a read-only query operation.
