# jupyter-notebook-execute

`station__jupyter__jupyter-notebook-execute` · external (needs EXECUTION_BACKEND_URL configured) · domain `jupyter` · pv-relevance `non-pv`

Execute all cells in a notebook using `jupyter nbconvert --execute --inplace`.

> **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.
