StorePilot

One MCP server for a whole app portfolio, across Google Play and the App Store.

Ask your assistant:

"Which of my apps has a crash rate above Google's threshold?"

"How much did the portfolio earn last month, per app?"

"Show me every app on both stores: version, rating, installs, revenue, crashes."

"The German description drifted between the two stores — what's different?"

"Ship 3.2.1 to the Play internal track and TestFlight."

Each question above is one tool call covering every app you own, because the tools are portfolio-shaped rather than endpoint-shaped. The last one is two, on purpose: writes preview first and wait for a human.

You need your own developer accounts — a Google Play service account, an App Store Connect API key, or both. StorePilot reads your accounts; it does not scrape public store listings.

Status: early. The read tools have run against real accounts on both stores; the money and crash-threshold paths have not returned real data yet, and no write has ever executed against a store. Read Status and honest limits before trusting a number.

What is actually different

Both stores, one tool set. Google Play via the Android Publisher API, the Play Developer Reporting API and the private Cloud Storage reports bucket; the App Store via App Store Connect. 34 tools total, named consistently.

Installs and earnings, which most tooling cannot reach. Play installs, ratings and earnings have no REST API. They exist only as UTF-16 CSVs in a private Cloud Storage bucket, so most tooling skips them and "how much did this app earn?" simply cannot be answered. StorePilot reads that bucket, resolves CSV columns by name rather than position, and reports earnings per currency without ever summing across currencies. (This path is implemented and fixture-tested but has not yet read a real report — see Status.)

Portfolio-first. portfolio_overview renders every app on both stores in one table. play_portfolio_health scans an entire Play account. Neither takes a package name. Built for indie devs, app factories and agencies.

Cross-store tools. parity_check finds listing and version drift between the two stores. compare_reviews puts both stores' reviews side by side. release_both ships one version to both. metadata_pull / metadata_push use fastlane's own directory layout, so adopting StorePilot never means abandoning fastlane.

Writes are gated. Every write previews first and returns a confirmation token that is HMAC-keyed to the exact operation, single-use, and expires in 10 minutes. Production releases are forced into a staged rollout capped at 20%.

setup_doctor. Credential setup here is a multi-step Google Cloud + Play Console + App Store Connect maze with several silent failure modes. One tool checks every step and prints the exact fix.

Install

Requires Python 3.11+.

git clone https://github.com/sonlenef/storepilot-mcp
cd storepilot-mcp
python3 -m venv .venv && .venv/bin/pip install -e .

That puts the server binary at .venv/bin/storepilot. Every client config below wants the absolute path to it.

Not yet on PyPI, so pip install storepilot does not work yet.

      "env": { "STOREPILOT_ASC_KEY_PATH": "/path/to/AuthKey_XXXXXXXXXX.p8" }
    }
  }
}

Codex CLI

Add to ~/.codex/config.toml:

[mcp_servers.storepilot]
command = "/absolute/path/to/storepilot-mcp/.venv/bin/storepilot"
env = { STOREPILOT_ASC_KEY_PATH = "/path/to/AuthKey_XXXXXXXXXX.p8" }

Configure only the store you use. Each adapter registers its tools independently, and the cross-store tools register as soon as either store is configured. See .env.example for every variable the code reads.

A .env file also works, but it is read from the process working directory — which is whatever directory your MCP client happened to launch the server from, not the repo. Use it when you run storepilot yourself from the checkout; use the client's env block otherwise.

Credentials are read from the environment and never written anywhere by StorePilot. Keep the service account JSON and the .p8 outside the repo, and chmod 600 both — they are private keys.

Start with setup_doctor

Do not start by calling a data tool and guessing why it returned nothing. Ask your assistant to run setup_doctor first. It checks each credential step independently, so one failure never hides the rest, and every failure carries its own fix.

With nothing configured yet:

StorePilot setup check
============================================================

-- Google Play ----------------------------------------------
[skip] Google Play: not configured
      Fix: Set STOREPILOT_GOOGLE_CREDENTIALS to the path of a service account JSON key. Full
      setup: create a Google Cloud project, enable the Android Publisher and Play Developer
      Reporting APIs, create a service account, download its JSON key, then invite the service
      account email in Play Console -> Users and permissions.
      Docs: https://developers.google.com/android-publisher/getting_started

-- App Store Connect ----------------------------------------
[fail] ASC credentials: App Store Connect is not configured: STOREPILOT_ASC_KEY_PATH,
      STOREPILOT_ASC_KEY_ID, STOREPILOT_ASC_ISSUER_ID unset.
      Fix: In App Store Connect go to Users and Access -> Integrations -> App Store Connect
      API, create a team key with the Admin or App Manager role, and download the .p8 file
      (Apple lets you download it exactly once). Then set STOREPILOT_ASC_KEY_PATH to that
      file, STOREPILOT_ASC_KEY_ID to the Key ID column, and STOREPILOT_ASC_ISSUER_ID to the
      Issuer ID shown above the key table. Sales reports additionally need
      STOREPILOT_ASC_VENDOR_NUMBER from Payments and Financial Reports.
      Docs: https://developer.apple.com/documentation/appstoreconnectapi/creating-api-keys-for-app-store-connect-api
[skip] ASC token: cannot test until the credentials load
      Fix: Fix the step above, then re-run setup_doctor.
[skip] ASC API reachable: cannot test until the credentials load
      Fix: Fix the step above, then re-run setup_doctor.
[skip] ASC sales access: cannot test until the credentials load
      Fix: Fix the step above, then re-run setup_doctor.

============================================================
Summary: 1 fail, 4 skip
Resolve the [fail] items above, then run setup_doctor again.

It also catches the failure that looks like success: without the Reply to reviews permission, Play's reviews API returns HTTP 200 and an empty list rather than an error, so "this app has no reviews" and "you lack a permission" are the same response. setup_doctor reports that ambiguity as its own diagnosis instead of guessing.

Full walkthrough for both stores: docs/SETUP.md.

Tools

34 tools. Full arguments, return shapes and per-tool limitations in docs/TOOLS.md.

Google Play — read

Google Play — write (all gated)

App Store Connect

Cross-store

Plus setup_doctor.

Nothing in either API says a Play package and an Apple ID are the same product, so the pairing lives in ~/.storepilot/apps.toml. Run suggest_app_pairs, then pair_apps for the proposals you agree with. A proposal is inert until written — a wrong pair would attribute one app's revenue, reviews and crash rate to another, and nothing downstream would look wrong.

The safety model

Every write is two calls. The first returns a preview and a token; the second carries that token back.

The preview is the actual safety mechanism: it renders into the chat, where a human can read "that is the wrong app" or "that is the production track". Play previews are not estimates — the operation runs for real inside a throwaway Play edit that is validated and then deleted, so the preview reports the version code Google actually assigned and any error Google would actually raise.

The token exists only to prevent drift between the preview and the confirmation. It is an HMAC over a canonical fingerprint of the operation, keyed with a per-install secret kept out of tool output, single-use, and valid for 10 minutes. A plain content hash would be computable by the model itself, letting it self-confirm without ever rendering the preview a human needs to see. Change any argument and the token stops working.

Three more rules:

• Production is forced into a staged rollout, capped at 20% on the first step (0.1 if you omit a fraction). play_expand_rollout is the only path to 100%, separated so it can never happen as a side effect.

• play_halt_rollout is deliberately ungated. Stopping a bad release is always the safe direction, and making someone do a second round trip during an incident is a design failure.

• Everything is audited — previewed, confirmed, rejected, executed, failed — to an append-only log at ~/.storepilot/audit.log, with credentials and long values redacted.

release_both issues one token for both stores, because approving half a two-store release is not approving the release. On partial failure it says exactly what landed where and rolls nothing back: pulling a working build from users because the other store returned an API error is worse than the drift.

Status and honest limits

StorePilot has been run against real accounts on both stores, read-only. That first run found three bugs, all fixed: Apple rejects sort on the appStoreVersions endpoint, the Play reports bucket is not always named pubsite_prod_rev_*, and bucket access is an account-level Play Console permission rather than the Cloud Console IAM grant the error message used to recommend.

Verified live — service-account and ES256 JWT auth, rate-limit pacing, setup_doctor on both stores, the Play and App Store read tools, and portfolio_overview rendering six apps across both stores in one table.

Not yet verified, and two of them carry headline claims:

• No vitals datapoint has ever come back. Android Vitals suppresses metrics below a minimum daily user count, and the test account's apps are under it. So the threshold comparison — the thing play_get_vitals exists for — has never run on real numbers, and the open question stands: does the Reporting API return 1.09 or 0.0109? A mismatch makes every verdict wrong by 100x.

• No report CSV has ever been read. Installs, ratings and earnings all come from the GCS bucket, and the parser has only ever seen fixtures. Google changed the earnings report's Fee Description column in July 2026, so the real headers are the risk.

• No write has ever executed. Every guard, preview and rollout policy is proven against a fake client and 503 tests, never against a real store.

• Apple sales reports return 403 for an App Manager key; reading them needs a key with finance access.

The full list is in docs/ROADMAP.md. If you run StorePilot against a real account — especially one with an app large enough to report vitals — those items are the most valuable bug reports you can file.

Hard limits, imposed by the stores

These cannot be fixed here, and StorePilot says so at the point of use rather than returning something that looks like an answer:

• Creating a new app record is Console-only on both stores. On Play the first upload must also be manual.

• Declaration forms are Console-only — Data safety, privacy nutrition labels, content rating.

• No REST endpoint uploads an iOS binary. asc_upload_build returns Transporter/altool instructions instead of pretending.

• Play's reviews API returns production-track reviews only, comment-bearing reviews only, roughly the last 7 days only.

• Apple publishes no aggregate rating through its API at all.

• Play report data lags 3–7 days, and a month's earnings land around the 5th of the following month. Before then the report does not exist, and StorePilot reports "not published" rather than 0.

Quotas

• Play Developer Reporting: 10 queries/second. StorePilot paces itself at 8 to leave headroom, so a large portfolio scan takes a few seconds.

• App Store Connect: ~3,600 requests/hour per key, reported in the x-rate-limit header, plus an undocumented per-minute ceiling that starts refusing around 300–350. The client paces against both, holding itself to 240 requests a minute and spacing calls out as the hourly budget runs down.

• Apple's salesReports is far scarcer than the rest of the API, so results are cached — past periods forever, since Apple never rewrites them.

How it compares

StorePilot is not the only MCP server touching these APIs, and it is not a fastlane replacement. docs/COMPARISON.md names the alternatives, says what each does better, and is specific about the narrow band where StorePilot is the only option.

Documentation

• docs/SETUP.md — the credential maze, end to end

• docs/TOOLS.md — every tool, argument and limitation

• docs/COMPARISON.md — alternatives, and fastlane

• docs/ROADMAP.md — state and the live-verification backlog

• docs/SECURITY.md — credential handling and the threat model

• CONTRIBUTING.md — setup, ground rules, and what actually helps

• CHANGELOG.md — what shipped, and what the live runs fixed

Contributing

The most useful contribution is running StorePilot against a real store account and reporting what breaks — particularly an account with an app large enough that Android Vitals reports data, which the test account was not. See CONTRIBUTING.md.
