## Why polymarket_get_markets is rated Low

This tool queries public market data without side effects. It performs a straightforward data retrieval operation typical of financial market data APIs. While financial data is involved, the tool itself does not move money, execute trades, or commit financial obligations—those are handled by sibling tools like polymarket_create_order and polymarket_cancel_order.

From the tool's own definition: "Tool retrieves market data (questions, end dates, token information) and explicitly states 'No authentication required.' The verb 'Get list' and absence of any creation, modification, deletion, or execution capability confirm read-only data retrieval."

## Use case

AI agents call polymarket_get_markets to retrieve information from Polymarket MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
