## Why sellStock is rated Critical

Despite the empty description, the tool name 'sellStock' combined with the server context (Zerodha Kite API for buying/selling stocks) makes it highly evident this tool executes a stock sell order, which is a financial transaction. Selling stocks moves assets and commits financial obligations, placing it firmly in the Financial category with critical severity due to potential for significant monetary loss if misused.

From the tool's own definition: "Tool name 'sellStock' on a server described as allowing users to 'buy/sell stocks'; sibling tools include 'buyStock', confirming this is a stock trading operation."

## Use case

AI agents use sellStock to commit financial operations through Zerodha Kite MCP Server, usually the final step of a payment, billing, or trading workflow. A call moves real money.
