bootstrap_refuter · DoWhy MCP v2 0 MCP: Risk & Policy

WHAT IT DOES

What bootstrap_refuter does on DoWhy MCP v2 0

AI agents invoke bootstrap_refuter 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 bootstrap_refuter needs a policy

This tool executes a statistical resampling (bootstrap) procedure to test/refute a causal estimate. It runs computations on existing data without deleting anything or moving money, but it triggers a multi-step analytical execution whose results depend on the arguments supplied. It falls under Execute (runs an analytical/statistical process) rather than Read (pure retrieval) or Write (data modification).

From the tool's definition bootstrap_refuter — applies a bootstrap-based refutation method (自举法反驳方法) which re-samples data and reruns causal estimation procedures
