## Why chart_set_symbol is rated Medium

This tool writes a new symbol to the chart configuration, changing what is displayed. It is reversible (you can change the symbol back), so it falls under Write rather than Destructive. Misuse could cause confusion or disrupt ongoing analysis workflows, hence medium severity.

From the tool's own definition: "'Change the chart symbol' — modifies the chart's displayed symbol/instrument"

## Use case

AI agents use chart_set_symbol to create or update resources in TradingView MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TradingView MCP Server environment.
