Gets a finished package listed on the Umbraco Marketplace: the NuGet tag, the dependency Marketplace reads version support from, the v14+ compatibility gotcha, and umbraco-marketplace.json. Use when a package is ready to publish, or when reviewing its packaging.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# umbraco-marketplace Getting listed is almost entirely automatic — there's no submission form, no review queue, no code-quality or security gate, and no revenue share. The whole mechanism is a NuGet tag plus a dependency reference. Most packages that "aren't showing up" just have one of those wrong. ## *How listing actually works* Marketplace syncs from NuGet, not from a submission: new packages are picked up daily, listing metadata refreshes every couple of hours, and there's a self-serve validator (marketplace.umbraco.com/validate) to check your metadata before or after publishing. There is no human review step and no stated code-quality, security, or "actively maintained" bar — see "What this skips, and why" below for what that means for this skill's scope. ## What actually gets you listed 1. **The `umbraco-marketplace` NuGet tag.** Add it to the package's `<PackageTags>` — and only to the top-level, installable package. Don't tag an internal `.Core`-style dependency package that isn't meant to be installed directly; that just duplicates the listing. 2. **A dependency on an Umbraco package.** Marketplace infers which CMS major version(s) your …

How to install
mdr add mattbrailsford/umbraco-devkit/umbraco-marketplace@sha256:c4079646dbec2ceaThe line at the top of this page pins the label git:20261017.8be9de3, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
