Analyze working capital changes and efficiency
AI agents call working_capital_analysis to retrieve information from Excel Finance MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool 'analyzes' working capital changes and efficiency, which is a read/query operation. It computes and reports on financial metrics but does not move money, modify data, or execute code. The word 'analyze' strongly implies a read-only calculation. Severity is low since misuse would at most produce misleading financial analysis rather than causing direct harm.
