get_markets
AI agents call get_markets to retrieve information from Polymarket Predictions MCP 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 market data from Polymarket without modifying, deleting, or executing external operations. It is a read-only data retrieval operation consistent with other Read-category tools on the server. The lack of side effects and alignment with predictable data access patterns make this low severity.
From the tool's definition Tool name 'get_markets' and server context (Polymarket Predictions MCP) suggest retrieval of market data. Sibling tools include 'get_events' and 'search_events', which are clearly Read operations.
