# mesh-network-simulate

`station__mesh__mesh-network-simulate` · external (needs EXECUTION_BACKEND_URL configured) · domain `mesh` · pv-relevance `pv-adjacent`

Tier: T3 (Domain-specific MCP tool)

> **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.
