WHAT IT DOES

What subscription_fees does on Open Stocks MCP

AI agents call subscription_fees 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 subscription_fees is rated Low

This tool retrieves subscription fee data from Robinhood—a read-only query with no side effects. While it relates to financial information, it does not move money, commit financial obligations, or execute trading actions. The 'gets' verb confirms data retrieval rather than modification or execution. Exposure risk is low because misuse would only expose fee information, not enable unauthorized transactions.

From the tool's definition Tool name 'subscription_fees' and description 'Gets Robinhood Gold subscription fees' indicate a query operation that retrieves financial information without modifying or executing any transactions.
