Read all Robinhood accounts, including account numbers and balances.
AI agents call get_accounts to retrieve information from Robinhood Agentic Trading without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation—it retrieves account information without modifying, deleting, or executing any actions. However, severity is high because the data retrieved (account numbers and balances across all accounts) is financially sensitive and could be misused by a compromised agent to identify targets for fraud, unauthorized transfers, or other financial crimes.
From the tool's definition Tool description states it 'Read[s] all Robinhood accounts, including account numbers and balances.' The verb 'Read' and the retrieval of account data (numbers, balances) clearly indicate a data query with no side effects.
