Get real-time stock price data for a specific CSE ticker symbol. Use search_company first to find the correct symbol.
AI agents call get_stock_data to retrieve information from CSE MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only queries and retrieves existing stock market data without any side effects, modifications, or code execution. It is a straightforward read operation that presents publicly available market information. The low severity reflects minimal risk even if misused by an AI agent, as it cannot modify markets, execute trades, or cause harm—it merely displays data.

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