Get the Stock Market holdings of the user on Zerodha
AI agents call get-zerodha-holdings to retrieve information from Zerodha MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is fundamentally a Read operation: it queries and retrieves user holdings data without side effects. Severity is elevated to 'high' rather than 'low' because the returned data is highly sensitive (reveals portfolio composition, asset allocation, and financial position), which could be misused if exposed to unauthorized parties or logged insecurely.
From the tool's definition Tool name and description explicitly state 'Get the Stock Market holdings' — a retrieval operation with no modification or execution. However, the data retrieved contains sensitive financial information (stock positions, quantities, valuations).
