WHAT IT DOES

What tab_list does on TradingView MCP Server

AI agents call tab_list to retrieve information from TradingView 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 tab_list is rated Low

This tool only retrieves and displays information about currently open tabs. It performs no mutations, does not execute code or commands, does not delete or modify data, and does not involve financial operations. The blast radius of misuse is minimal—an AI agent querying this information could only learn what tabs are open, which poses no security or operational risk. This is a straightforward Read operation.

From the tool's definition Tool name is 'tab_list' and description states it will 'List all open TradingView chart tabs' — a pure query operation that retrieves information about UI state with no side effects or modifications.
