Check how well retrieved context is used in the generated answer
AI agents call rag.measure_context_utilization to retrieve information from ContextForge MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries metrics about how context is being utilized in answers. It performs an observational/analytical function without side effects, modification of data, or triggering external operations. It fits the 'Read' category as a retrieval and query operation. Low severity because misuse would only expose metrics or analysis data, not cause damage or data loss.
From the tool's definition Tool name 'measure_context_utilization' and description 'Check how well retrieved context is used in the generated answer' indicate a read-only analysis operation.
