Seed a Mendix app's PostgreSQL database directly, bypassing the runtime — Mendix's internal ID system, association storage, and bulk `import from` an external database. Use when populating test or demo data, when data is needed before the UI exists, or for imports too large for the runtime.
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.

How to install
mdr add mendixlabs/mxcli/demo-data@sha256:5e642ff745a67f08The line at the top of this page pins the label git:20261024.2f6970c, 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.
