Get volume statistics for different timeframes (24h, 7d, 30d, all-time).
AI agents call get_market_volume 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 returns volume statistics—a read-only operation with no side effects on market state, user positions, or financial obligations. Despite being on a financial trading server, the tool itself performs data query/analysis only. The low severity reflects minimal risk even if called inappropriately by an agent, as it cannot execute trades, move funds, or alter positions.
