WHAT IT DOES

What schwab_accounts does on Open Stocks MCP

AI agents call schwab_accounts 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_accounts is rated Low

This tool retrieves account information (balances and positions) without creating, modifying, deleting, or executing any financial transactions. It is a read-only query of account state. The severity is low because while exposure of account details carries some confidentiality risk, the tool itself performs no irreversible actions or fund movements.

From the tool's definition Tool name 'schwab_accounts' and description 'Get all Schwab linked accounts with balances and positions' indicate data retrieval only. Verbs 'Get' and 'with' (indicating passive data presentation) show no modification, deletion, or execution of trades.

schwab_accounts Allowed
