AI agents call get_nepse_subindex to retrieve information from Nepse API MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves or queries market data with no side effects. Despite the empty description, the consistent naming pattern across the server (all sibling tools are data retrieval operations for Nepal Stock Exchange) and the server's stated purpose of 'querying real-time stock data' confirm this is a Read operation.
