Search for prediction market events by keyword. Events group related markets together. This is useful for finding markets on specific topics.
AI agents call search_events to retrieve information from Polymarket 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 and queries data (searches events) with no side effects, modifications, or state changes. It falls squarely into the Read category. Severity is low because unauthorized search queries on prediction markets pose minimal risk - they expose only public market information without enabling harmful actions.
From the tool's definition search_events searches for prediction market events by keyword with no mention of creating, modifying, or deleting data. The description states it is 'useful for finding markets on specific topics' - a pure query operation.
