# run-causality-evidence-aggregator

`station__microgram__run-causality-evidence-aggregator` · external (needs EXECUTION_BACKEND_URL configured) · domain `microgram` · pv-relevance `pv-core`

Aggregates temporal association, dechallenge/rechallenge, and Naranjo score into unified causality verdict. Bridges temporal-association + dechallenge-rechallenge + naranjo-quick outputs.

> **Note:** This tool routes through an external execution backend. If `EXECUTION_BACKEND_URL` is unset on the server, calls return JSON-RPC error `-32603 "Tool execution backend not configured"`. Tools with `backend: native` execute in-process and are always callable.
