Check if the FreeTaxUSA session is active and which tax year/section is loaded.
AI agents call get_session_status to retrieve information from FreeTaxUSA MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only check of session status and tax year/section information. It has no side effects, does not modify any data, does not execute code or commands, and does not involve financial transactions. While the broader server context involves tax filing (a financial domain), this specific tool merely queries current session state, placing it squarely in the Read category with low severity.
From the tool's definition Tool name 'get_session_status' and description 'Check if the FreeTaxUSA session is active and which tax year/section is loaded' indicate a query operation that retrieves session state without modifying data or triggering external effects.
