## Why get_market is rated Low

This tool queries and returns metadata about a market (e.g., 'HYPE', 'ETH'). It performs a read-only lookup with no ability to modify data, execute trades, delete data, or incur financial obligations. The blast radius of misuse is minimal—an agent could only retrieve information already publicly available on the DEX.

From the tool's own definition: "Tool name 'get_market' and description 'Get metadata for a single market by symbol' indicate a query operation that retrieves market information without side effects."

## Use case

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

## Recommended policy (PolicyLayer)
