navigate_section · FreeTaxUSA MCP Server MCP: Risk & Policy

WHAT IT DOES

What navigate_section does on FreeTaxUSA MCP Server

AI agents invoke navigate_section to trigger actions in FreeTaxUSA 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 navigate_section needs a policy

While the tool itself only navigates the UI rather than modifying tax data, it is an Execute operation because it triggers browser actions within a financial/tax-processing context. The severity is high because misuse could allow an AI agent to navigate to unintended tax sections, trigger premature filings, or access sensitive tax information.

From the tool's definition Tool automates browser navigation within a tax filing system (FreeTaxUSA). Description states it 'Jump[s] to a specific tax section by name' and is part of a suite that includes form filling and filing operations.
