WHAT IT DOES

What remove_from_watchlist does on Open Stocks MCP

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

RISK

Why remove_from_watchlist is rated Critical

Removing symbols from a watchlist is a destructive action: the association between the symbol and the watchlist is deleted. While not financially harmful, it is an irreversible data deletion (without an explicit undo/restore tool). Severity is medium because the blast radius is limited to watchlist management and does not directly affect trades or account holdings.

From the tool's definition 'Removes symbols from a watchlist' — the word 'removes' indicates an irreversible deletion of items from a watchlist.
