WHAT IT DOES

What list_deals does on :GT Protocol MCP Server

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

RISK

Why list_deals is rated Low

This tool retrieves and displays existing deal records without modifying, executing, or deleting any data. While the GT Protocol server context involves financial trading, list_deals itself only performs queries. It does not commit financial transactions, execute trades, or modify account state. The filtering capability is a standard read operation pattern.

From the tool's definition Tool name is 'list_deals' and description states 'List all deals (open and closed) with optional filters.' The verb 'list' and the function of retrieving/querying deal information with optional filters indicates data retrieval with no side effects.
