WHAT IT DOES

What refutation_test_suite does on DoWhy MCP v2 0

AI agents invoke refutation_test_suite 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 refutation_test_suite needs a policy

The tool executes a suite of refutation tests against causal models. This involves running computational procedures (statistical tests) rather than simply reading data or writing records. It does not delete data or move money, but it actively runs test computations whose scope and effects depend on the inputs provided.

From the tool's definition "运行全面的反驳测试套件" (run comprehensive refutation test suite) — triggers execution of multiple statistical tests
