# graph-analyze

`station__graph-ops__graph-analyze` · external (needs EXECUTION_BACKEND_URL configured) · domain `graph-ops` · pv-relevance `non-pv`

Analyze a graph structure.

> **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.
