# run-multi-signal-combiner

`station__microgram__run-multi-signal-combiner` · external (needs EXECUTION_BACKEND_URL configured) · domain `microgram` · pv-relevance `pv-core`

Combines PRR, ROR, IC, and EBGM signal classifications into an overall pharmacovigilance signal assessment. Two or more STRONG signals yield CONFIRMED; one STRONG yields PROBABLE; MODERATE counts determine POSSIBLE/SUGGESTIVE.

> **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.
