WHAT IT DOES

What authenticate does on Zerodha Trading Bot - MCP Server

AI agents invoke authenticate to trigger actions in Zerodha Trading Bot - MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why authenticate needs a policy

Authentication is not a simple read operation; it executes an external API call that creates a privileged session granting access to financial trading operations. Misuse could allow an AI agent to establish unauthorized access to a live trading account, enabling subsequent order placement, portfolio manipulation, or financial transactions.

From the tool's definition 'Authenticate with Zerodha using request token' — triggers an external authentication operation against Zerodha's API, establishing a session that enables trading capabilities
