get_markets
AI agents call get_markets to retrieve information from Meridian Edge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves market data from the prediction market aggregator with no side effects. It does not create, modify, delete, or execute operations. The empty description reduces confidence slightly, but the server's stated purpose and naming convention of all tools (get_X, search_X patterns) confirm this is a read-only retrieval operation.
From the tool's definition Tool name 'get_markets' combined with server context describing 'Real-time prediction market consensus data' and sibling tools like 'get_consensus', 'get_movers', 'search_markets' indicate data retrieval.
