Get list of all market groups
AI agents call get_market_groups to retrieve information from EVE Tycoon 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 market group data from the EVE Tycoon API without any side effects. It is a simple query/list operation that reads static reference data about market structure. There is no capability to modify, delete, or execute external operations. The blast radius of misuse is minimal—an agent could only retrieve market data that is already public.
From the tool's definition Tool name is 'get_market_groups' and description states 'Get list of all market groups' — a retrieval operation with no modification, deletion, or execution of commands.
