Get lists from Bandmate. Returns public lists, or if userId is provided, returns user
AI agents call get_lists to retrieve information from Bandmate 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 existing list data (public lists or user-specific lists when userId is provided). It performs no creation, modification, deletion, or execution of operations. The action is read-only, making it a Read category tool with low severity, as unauthorized access to lists carries minimal risk in the context of a music collaboration application.
From the tool's definition Tool name 'get_lists' and description 'Get lists from Bandmate. Returns public lists...' indicate data retrieval with no modification or side effects.
