get_class_info
AI agents call get_class_info to retrieve information from DM20 Protocol without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool appears to retrieve class information from D&D 5e rules, which is a read-only operation with no side effects. No data is modified, deleted, or financial impact occurs. Even in the context of an AI agent, retrieving game mechanics poses minimal risk. The empty description slightly reduces confidence, but the name and server purpose strongly indicate this is a simple informational lookup.
From the tool's definition Tool name 'get_class_info' indicates a retrieval operation. Sibling tools like 'ask_books' and 'build_encounter_tool' suggest this server queries game data and rules.
