Get E*TRADE OAuth authorization URL.
AI agents call etrade_get_auth_url to retrieve information from E*TRADE MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

While it is part of an authentication flow, it does not itself modify state, execute transactions, or access financial data. It is a prerequisite step that enables other tools but carries no independent side effects beyond returning a URL string.
From the tool's definition Tool name 'etrade_get_auth_url' and description 'Get E*TRADE OAuth authorization URL' indicate it retrieves/generates an authorization URL endpoint.
