## Why close_all_positions is rated Critical

Closing all open positions is a financially destructive and irreversible market action. Once positions are closed at market price, the trades are executed and cannot be undone. Misuse by an AI agent could liquidate an entire portfolio instantly, causing significant financial loss, especially in unfavorable market conditions.

From the tool's own definition: "'Closes all open positions' - closes ALL open positions simultaneously with no filtering or partial selection"

## Use case

AI agents call close_all_positions to permanently remove resources in Alpaca MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)
