WHAT IT DOES

What schwab_quotes does on Open Stocks MCP

AI agents call schwab_quotes 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 schwab_quotes is rated Low

This tool retrieves real-time stock price quotes from the Schwab broker API. It is a simple read operation that queries existing market data and returns it to the caller. There are no side effects, no data modification, no code execution, and no financial transactions involved. The severity is low because quote data is public market information with no blast radius if misused by an AI agent.

From the tool's definition Tool name 'schwab_quotes' and description 'Get current quotes for multiple stock symbols from Schwab' indicate data retrieval without modification or execution.

RECOMMENDED RULE

The rule that runs schwab_quotes safely

schwab_quotes Allowed

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

The button opens the PolicyLayer dashboard: create your workspace, connect Open Stocks MCP, apply this rule, and every schwab_quotes call is checked against it from then on.
