AI agents call get_holdings to retrieve information from Turtlestack Lite without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing portfolio data. It performs no write operations, does not execute code or external operations, and does not delete or move money.

As a read operation with no destructive, financial, or execution implications, it is categorized as Read with low severity.

"version": "1",
"default": "deny",
"tools": {
"get_holdings": {}
}
