# run-crypto-composite

`station__microgram__run-crypto-composite` · external (needs EXECUTION_BACKEND_URL configured) · domain `microgram` · pv-relevance `pv-core`

Aggregate 4 crypto micrograms into single GREEN/YELLOW/RED. RED if any red, YELLOW if any yellow, GREEN otherwise (grey=green).

> **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.
