Browse Kalshi events (an event groups related markets, e.g. an election or a game). Filter by status / seriesTicker; page with limit + cursor. Returns event ticker, series, title, category, and market count. Read-only (no Kalshi key needed).
AI agents call predict.kalshi-events to retrieve information from Mcp 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 public event data from Kalshi with no capability to modify, delete, execute commands, or transfer funds. It is a straightforward read operation with minimal security risk.
From the tool's definition Tool description explicitly states 'Read-only (no Kalshi key needed)' and lists browsing/filtering/pagination operations that retrieve event metadata (ticker, series, title, category, market count) with no side effects.
