Get recent market trades.
AI agents call trades to retrieve information from Aster Finance MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves market trade information and has no side effects. It falls squarely into the Read category as it queries existing data without creating, modifying, deleting, or executing operations. The blast radius is minimal—an AI agent could only gain market information.
