Gets comprehensive account details including buying power and cash balances.
AI agents call account_details to retrieve information from Open Stocks MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves financial account information (buying power, cash balances) without modifying or executing transactions. It is a Read operation. However, severity is high rather than low because the data retrieved is sensitive financial information that could be exploited if an AI agent leaks or misuses it (e.g., disclosing account balances, enabling social engineering).
From the tool's definition Tool name 'account_details' and description 'Gets comprehensive account details including buying power and cash balances' indicate data retrieval with no modification. The word 'Gets' confirms read-only operation.

PolicyLayer is an MCP gateway — it sits between your AI agents and Open Stocks MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for account_details:
{
"version": "1",
"default": "deny",
"tools": {
"account_details": {}
}
}account_details is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
