get_event_by_slug
AI agents call get_event_by_slug to retrieve information from Polymarket without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves event data by slug identifier from Polymarket's public API. Following the established pattern of other tools on this read-only server, it queries and returns data without modifying, deleting, or executing operations. The 'get_' prefix and slug-based lookup confirm it is a read operation with minimal blast radius.
From the tool's definition Server is explicitly described as 'read-only interface' and sibling tools (get_activity, get_book, get_market_by_slug, get_price, etc.) are all retrieval operations.
