Install an app from the registry or a GitHub URL. Interactive — shows permissions summary, prompts for env vars, polls to completion, and reports proxy URLs.
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
# /install-app — Install an App Store App Arguments passed: `$ARGUMENTS` --- ## Argument formats - `/install-app <registry-name>` — install latest version from registry - `/install-app <registry-name> <version>` — install specific version - `/install-app <github-url>` — custom GitHub install (installs the latest commit on the default branch) - `/install-app <github-url> <40-hex-commit>` — custom GitHub install pinned to a specific commit --- ## Step 1 — Resolve the app **Registry install:** call `browse_registry` with the app name to get its versions list. Show the user: - App name and description - Repo URL - Version you will install (and whether it is latest) **GitHub install:** the commit is **optional**. - If the user supplied a commit, validate it is a 40-char hex string; if it is malformed, tell the user and stop. - If **no commit** was given, do **not** ask the user to find one — call `install_app` with just the `github_url` and the installer resolves the default branch's latest commit (HEAD) automatically and pins it. Report the resolved commit in Step 5. If the app is not found in the registry and no GitHub URL given, stop with a helpful message. --- …

How to install
mdr add 0xmaxma/claude-gateway/install-app@sha256:2bbc9e92e34f76dfThe line at the top of this page pins the label git:20261017.005bf00, 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.
