WHAT IT DOES

What population_counterfactual does on DoWhy MCP v2 0

AI agents invoke population_counterfactual to trigger actions in DoWhy MCP v2 0. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why population_counterfactual needs a policy

This tool executes counterfactual analysis computations using the DoWhy framework. It performs statistical/causal modeling operations that process data and produce derived results. It does not merely read stored data, nor does it write or delete anything — it runs a computational analysis.

From the tool's definition "分析人群反事实结果" (analyze population counterfactual outcomes) — runs causal inference computations over population-level data using DoWhy
