rollout

Ship an Android release without opening Play Console. rollout is the CLI and MCP server that lets you (or your favorite AI agent) push a build to a track, watch a staged rollout climb, halt it if things look wrong, and answer "why did our crash rate spike" — all from a terminal instead of a maze of dashboard tabs. Store listings and user reviews come along for the ride. It talks straight to the Android Publisher and Play Developer Reporting APIs from your own machine — no relay server sitting between you and your app's data.

It ships as a single binary with two front-ends over one shared set of tools:

• CLI — rollout play releases, rollout play tracks, rollout play promote …. Scriptable, pipeable into jq, usable in CI. This is what the bundled agent skill drives.
• MCP server — rollout mcp serves the same tools over stdio to MCP hosts (Claude Desktop, Cursor, …), so an agent can manage your release the same careful way you would.

rollout play releases --format table

track       | status     | version_codes | rollout_percent | name
------------+------------+---------------+-----------------+------
production  | completed  | ["41"]        |                 | 1.4.0
production  | inProgress | ["42"]        | 10              | 1.5.0
beta        | completed  | ["43"]        |                 | 1.6.0

Nothing mutates on the first ask. Every write — halting a rollout, promoting a build, editing a listing — comes back as a preview and a confirm token first. You (or the agent) apply it on purpose, or it expires.

Platforms

Platform	Setup guide	Surface
Google Play	docs/play.md	53 tools — tracks, releases, listings, in-app products and subscriptions, reviews, Android vitals, and the CSV report exports

The platform registry exists so a second store (App Store Connect is the obvious one) is a new file rather than an edit to the shared auth, config, and safety plumbing.

Install

Three ways in, no wrong answer:

• Homebrew (macOS/Linux):

  brew install Limetric/tap/rollout

• Prebuilt binary — grab one from the releases page.

• Build from source:

  go build -o build/rollout .

Quick start

rollout login play                              # guided setup + live check
rollout config play set-package com.example.app # so --package can be omitted
rollout play tracks

CI skips the wizard:

export PLAY_SERVICE_ACCOUNT_FILE=/path/to/key.json
export PLAY_PACKAGE_NAME=com.example.app
rollout doctor play

Don't forget to invite the credential in Play Console → Users & permissions — authenticating isn't the same as having access. Details in docs/play.md.

Integrations

As an MCP server

rollout mcp serves the same tools over stdio, under a platform prefix — play_tracks, play_releases, play_reviews, … Point your host at the binary and pass credentials through the environment, no config file needed:

{
  "mcpServers": {
    "rollout": {
      "command": "rollout",
      "args": ["mcp"],
      "env": {
        "PLAY_SERVICE_ACCOUNT_FILE": "/path/to/key.json",
        "PLAY_PACKAGE_NAME": "com.example.app"
      }
    }
  }
}

A platform whose credentials don't resolve is skipped with a note on stderr rather than taking the whole server down, so an unconfigured second store never blocks the first.

As a Claude Code plugin

The repo bundles a skill (plugins/rollout/skills/rollout/SKILL.md) that teaches an agent when and how to drive the CLI. If you installed rollout via Homebrew and don't have the repo cloned, install it as a plugin instead:

/plugin marketplace add Limetric/rollout
/plugin install rollout@rollout

Concepts

Writes preview first

Every mutating call returns a preview and a confirm token before it touches anything:

rollout play release halt --track production
# → preview + confirm token, valid for 10 minutes
rollout confirm <token>       # applies it (or re-run with --confirm <token>)
rollout audit                 # log of every write rollout has applied

Writes are transactional — a release write opens a fresh edit, mutates one release, validates, and commits, deleting the edit on any failure, so nothing is left half-staged. It also reads the track first and touches only the release it names, so an in-progress rollout is never dropped by a write that didn't mention it. Halting a rollout, completing a production rollout, and deleting a listing or image type ask for a second confirmation, since none of those undo with the opposite command.

Guard rails are optional and off by default — a production lock, a rollout percentage ceiling, a blocked-operations list — and they're re-checked at confirm time, not just when the preview is issued. See docs/play.md for the full list.

Where the refresh token lives

rollout login play writes the refresh token to a per-platform token store (0600, under the config directory), never to config.toml and never to an environment variable:

rollout doctor play                     # store location, writability, sign-in age
export ROLLOUT_TOKEN_STORE=/path/to/tokens   # containers/CI: mount a writable volume

A service-account JSON key skips the token store entirely and wins when both credential modes are configured — it's what CI and Google's own docs recommend for the Publisher API.

Defaults and output

rollout config play set-package com.example.app   # drop --package everywhere else
rollout play releases --format table               # or --format csv for a spreadsheet
rollout play vitals --metric crashrate --dimension versionCode | jq '.rows'

Reads print JSON by default, so they pipe straight into jq. Human-facing output — login, doctor, config show, table headers, write previews — is colored on a terminal and plain everywhere else, so scripts and rollout audit stay byte-identical either way. Override with --color always|never|auto; NO_COLOR and TERM=dumb are honored too.
