Use when deploying an app to Railway — pushing a repo or running railway up, provisioning a managed database, wiring env and reference variables across services, attaching a volume, or fixing a deploy that builds but will not serve. NOT Render (that is `render`), NOT Fly machines (that is `fly-io`), NOT a self-hosted PaaS on your own box (that is `coolify`).
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
# Railway — ship a repo to a managed PaaS Railway is an opinionated PaaS: connect a GitHub repo or run `railway up`, and it builds your code (Railpack by default, or your Dockerfile), runs the container, networks it, and hands you a domain. You manage *services, environments, variables, volumes, and databases* — not servers, not an OS. This skill makes you fast and correct on Railway's specific surface, not generic deploy theory. ```text repo / `railway up` → Railpack (or Dockerfile) build → container runs (binds 0.0.0.0:$PORT) → variables + reference vars injected → private net (*.railway.internal) + public domain ``` ## Is Railway the right target? Settle this before touching config. If the user named the platform, honor it and route. | Want | Use | Why / route | | --- | --- | --- | | Push a repo, get a built+running app with zero ops | **Railway** (this skill) | Managed PaaS, Railpack build, by-the-minute billing | | `render.yaml` Blueprint, free static sites, their dashboard model | `render` | Different PaaS — route to the `render` skill | …

How to install
mdr add ericrisco/rsc-harness/railway@sha256:a258732503c30c35The line at the top of this page pins the label git:20260729.086c7b3, 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.
