AI agents call get_capital_assumptions to retrieve information from SEC MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves financial data (capital expenditure and working capital assumptions) from the SEC database without creating, modifying, deleting, or executing any operations. It is a straightforward query of existing financial information with no side effects, fitting the Read category. The severity is low because retrieving public SEC filing data poses minimal risk even if misused by an AI agent.
