Get the change history for a variable.
AI agents call get_variable_history to retrieve information from Qontinui Web MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves historical change data for a variable. It performs a read-only operation that does not create, modify, delete, execute code, or move money. The blast radius is minimal as it only exposes existing historical information without enabling any state changes or external operations.
From the tool's definition Tool name 'get_variable_history' and description 'Get the change history for a variable' indicate retrieval of historical data with no modification or side effects.
