WHAT IT DOES

What all_watchlists does on Open Stocks MCP

AI agents call all_watchlists to retrieve information from Open Stocks MCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why all_watchlists is rated Low

This tool queries and returns existing watchlist data without creating, modifying, deleting, or executing any operations. It is a straightforward read operation that retrieves user data. While the server overall has Financial and Execute capabilities (implied by 'trading capabilities' and broker integrations), this specific tool only reads watchlist information, posing minimal risk.

From the tool's definition Tool name 'all_watchlists' and description 'Gets all user-created watchlists' indicate a retrieval operation with no modification or side effects.

RECOMMENDED RULE

The rule that runs all_watchlists safely

all_watchlists Allowed

all_watchlists is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
