Umbraco Cms MCP Dev runs on your own machine — the client starts it, so there is no endpoint to ping. 1 362 installs a week from npm. Last commit 21 Oct 2026.
A developer focused model context protocol (MCP) server for Umbraco CMS
Today is the operative word: we check Umbraco Cms MCP Dev every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.
