AI agents call list_group_bonuses to retrieve information from TDC MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and lists existing group bonus data from the True Dungeon Card (TDC) system. It performs a read-only query operation similar to sibling tools like 'get_bonuses_for_token' and 'list_rulebook_pages'. There is no indication of data creation, modification, deletion, code execution, or financial impact.
From the tool's definition Tool name is 'list_group_bonuses' and description states it 'List[s] all True Dungeon group bonuses with their tier effects.' This is a retrieval operation with no modification or side effects.
