Retrieve key stock ratios for a given ticker symbol.
AI agents call get_Ratio to retrieve information from MCPServerDemo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves financial ratio data for a ticker symbol without creating, modifying, deleting, or executing operations. This is a straightforward read operation with minimal risk if misused by an AI agent, as it only fetches pre-calculated financial metrics.
From the tool's definition Tool name is 'get_Ratio' and description states 'Retrieve key stock ratios' — both indicate data retrieval with no modifications or side effects.
