AI agents call get_stock_info to retrieve information from MaverickMCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns static financial information about stocks without creating, modifying, deleting, executing code, or moving money. It is a pure read operation with no side effects. The low severity reflects minimal risk even if misused—returning public financial data poses no direct harm.

PolicyLayer is an MCP gateway — it sits between your AI agents and MaverickMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for get_stock_info:
{
"version": "1",
"default": "deny",
"tools": {
"get_stock_info": {}
}
