Appstore

A CLI + bundled MCP server for managing App Store Connect metadata, screenshots, and in-app purchases from YAML files. Designed for teams that want their store listing under version control instead of click-driven through the App Store Connect website.

📖 Documentation: https://zmij.github.io/appstore-cli/ (llms.txt available for agents at /llms.txt)

Naming note. The npm package is appstore-flow. The GitHub repo is zmij/appstore-cli and the docs site lives at zmij.github.io/appstore-cli/ — slugs kept from before the rebrand so existing links keep working. The local config filename appstore-cli.config.yaml is also a legacy holdover.

What it does:

• Pull every per-locale listing, IAP, subscription, custom-product-page, and screenshot summary into committed YAML.
• Push YAML edits back to ASC: localised copy, prices, availability, subscription intro offers, review screenshots.
• Create new IAPs and subscriptions from YAML.
• Two-way reconcile: pull live state into committed YAML without overwriting hand-edits; field-level diff with paths like subscriptions/my_sub/intro_offers/FREE_TRIAL+ONE_WEEK+1+__global/start_date.
• Migrate existing subscribers when a price changes.

Same code is exposed as an MCP server so an agent can read/list/update store state without shelling out.

Originally extracted from a working Lazy Sudoku setup. Defaults match that layout (.secret-stuff/ + l10n/metadata/apple/); downstream projects can either adopt the same conventions (no config needed) or override via appstore-cli.config.yaml / env vars — see Configuration.

Install

npm install -g appstore-flow
# or, from a checkout (the GitHub repo is still `appstore-cli` — only the
# npm package name has been rebranded to `appstore-flow`):
git clone https://github.com/zmij/appstore-cli.git
cd appstore-cli && npm install && npm run build && npm link

Authentication

You need an App Store Connect API key. The .p8 file plus the issuer ID + app ID go in a config file:

# .secret-stuff/appstore-config.yaml (gitignored — never commit)
issuer_id: "8a8a8a8a-1234-5678-9abc-def012345678"
app_id: "1234567890"

keys:
  app_manager:
    key_id: "ABCDE12345"
    key_file: "AuthKey_ABCDE12345.p8"
  build_upload:
    key_id: "FGHIJ67890"
    key_file: "AuthKey_FGHIJ67890.p8"

default_key: "app_manager"

Multiple keys let you separate concerns (one for build uploads, one for metadata edits). Pick a non-default key per call with --key-id.

See docs/auth.md for key creation and the JWT lifecycle.

Configuration

The defaults match the layout this tool was extracted from:

What	Default	Where
Secrets directory	.secret-stuff/ at project root	Holds appstore-config.yaml + .p8 files
Metadata directory	l10n/metadata/apple/ at worktree root	Holds listings/<lang>.yaml, iap.yaml, screenshots/order.yaml

To override, drop an appstore-cli.config.yaml at the worktree root (preferred) or project root:

# appstore-cli.config.yaml
secrets_dir:  config/appstore-secrets     # relative to project root
metadata_dir: store-metadata/apple        # relative to worktree root

Env vars win over the file:

APPSTORE_SECRETS_DIR=/path/to/secrets
APPSTORE_METADATA_DIR=/path/to/metadata

The CLI uses git to find the project root (so secrets live with the main repo, not in worktrees) and the worktree root (so per-branch metadata edits stay local).

Quickstart

# 1. Pull current ASC state into YAML
appstore iap export --output l10n/metadata/apple/iap.yaml

# 2. Edit the YAML in your editor
$EDITOR l10n/metadata/apple/iap.yaml

# 3. Preview the push
appstore iap sync --dry-run

# 4. Push
appstore iap sync

Same flow for listings:

appstore listings update --all --dry-run
appstore listings update --all

See docs/workflow.md for the full export → edit → sync → pull loop.

Commands

App + version info

appstore info                                       # bundle ID, name, SKU, primary locale
appstore versions list                              # all app versions

Listings

appstore listings list --version-id X
appstore listings show --lang en-GB
appstore listings update --all [--dry-run]
appstore listings update --lang en-GB --field whats_new
appstore listings diff                              # YAML vs live

In-App Purchases + subscriptions

appstore iap list                                              # quick stats
appstore iap show <productId>                                  # full detail
appstore iap export --output l10n/metadata/apple/iap.yaml      # overwrites file
appstore iap sync [--product-id X] [--dry-run]                 # YAML → ASC
appstore iap create [--product-id X] [--dry-run]               # provision new
appstore iap pull [--product-id X] [--dry-run]                 # ASC → YAML (additive)
appstore iap diff [--product-id X]                             # field-level divergence
appstore iap migrate-prices --product-id X [--territory T] [--confirm]

Subscriptions, subscription groups, intro offers, review screenshots all round-trip through iap.yaml. See docs/iap-schema.md for the YAML schema.

Screenshots

appstore screenshots list --lang en-GB
appstore screenshots upload --source ./shots --lang en-GB --mode replace
appstore screenshots upload --source ./shots --all --mode replace
appstore screenshots reorder --all

Modes: replace (drop + re-upload), add (append), reorder (no upload, reorder existing).

Custom Product Pages

appstore pages list

App Previews (video)

appstore previews list --lang en-GB
appstore previews upload --source ./reels --lang en-GB

MCP Server

The package ships a bundled MCP server (appstore-mcp) using the same client code as the CLI. Any MCP-aware agent — Claude Code, Cursor, Windsurf, Cline, Continue, Zed — can talk to it over stdio.

Prerequisites

appstore-mcp must be on $PATH. The Install step puts it there (either npm install -g appstore-flow or npm link from a checkout). Verify:

which appstore-mcp

If you'd rather not install globally, register an absolute path instead — see below.

Register with Claude Code

# Run from the project whose store listing you manage — that becomes the
# server's working directory, which is where config + metadata YAMLs are
# resolved from. See "Working directory and auth" below.
claude mcp add appstore appstore-mcp

claude mcp add defaults to local scope (your account, this directory). Pick the scope that fits:

Scope	Where it's stored	Use when
--scope local (default)	~/.claude.json, keyed by cwd	Personal experiments in one repo
--scope project	<repo>/.mcp.json (committed)	Everyone in the repo gets it
--scope user	~/.claude.json global	You want it everywhere

If you skipped npm link, register the build output directly:

claude mcp add appstore node /absolute/path/to/appstore-cli/build/mcp/server.js

Register with other MCP clients

Clients that read a JSON config (Cursor, Windsurf, Cline, Continue, Zed, …) take this shape. Point command at the binary on $PATH, or use an absolute path:

{
  "mcpServers": {
    "appstore": {
      "command": "appstore-mcp"
    }
  }
}

Consult your client's docs for where this config file lives — common paths are ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp_config.json, or a workspace-level file.

Working directory and auth

The MCP server inherits its working directory from the client that spawns it. Path resolution (where appstore-config.yaml and metadata YAMLs live) starts from git rev-parse --show-toplevel of that cwd, with one refinement: when the server detects it's running inside a git submodule (via git rev-parse --show-superproject-working-tree), it resolves paths against the parent worktree instead of the submodule's own root.

Practical implications:

• Launch your MCP client from the repo whose store listing you manage. The server then finds .secret-stuff/appstore-config.yaml and the metadata YAMLs from there.
• If your client launches from somewhere else, override paths via env vars passed through the client config:

{
  "mcpServers": {
    "appstore": {
      "command": "appstore-mcp",
      "env": {
        "APPSTORE_SECRETS_DIR": "/abs/path/to/secrets",
        "APPSTORE_METADATA_DIR": "/abs/path/to/metadata"
      }
    }
  }
}

See Configuration for the full env var list.

Verify

claude mcp list

Then in a session, ask the agent to call appstore_get_app_info — the first tool call confirms wiring. An "auth failed" error means wiring is fine and you just need a valid appstore-config.yaml.

Tools exposed

Tool	Description
appstore_get_app_info	Bundle ID, name, SKU, primary locale, relationships
appstore_list_versions	All app versions
appstore_list_localisations	Per-locale metadata (with locales filter + summary + truncateLength)
appstore_show_listing	One locale on the editable version
appstore_update_listing	Patch one locale's fields (only supplied fields touched)
appstore_list_iap	All in-app purchases
appstore_list_subscriptions	All subscription groups
appstore_list_pages	All custom product pages
appstore_screenshot_summary	Per-locale × per-device screenshot counts

Auth + paths come from the same config files as the CLI; no separate setup.

Key selection

Priority order:

1. --key-id <name> flag
2. APPSTORE_KEY_ID env var
3. default_key from the config file

# Use a specific key
appstore versions list --key-id build_upload

Apple quirks worth knowing

The Apple side has several non-obvious gotchas the CLI works around. Captured in docs/quirks.md:

• Edit sessions are listings-only. IAPs and subscriptions skip the session.
• preserveCurrentPrice is the migration discriminator. iap sync writes true (new subscribers only); iap migrate-prices writes false (existing too).
• Subscription price points are per-territory. No "auto-equalise everywhere" call — the anchor migration only affects the anchor's territory.
• Apple chooses the consent flow from the price delta. Decreases auto-apply; increases trigger Apple's notification + opt-in flow.
• subscriptionPrices.create requires picking a tier price point ID — you can't pass a free-form $4.99. The CLI finds the matching tier for you.

Adopters

I built this to manage Lazy Sudoku's App Store listing — 14 locales, 12 IAP products across 173 territories of pricing, plus subscription groups with intro offers. Editing YAML in my editor and running appstore listings sync / appstore iap sync is dramatically less error-prone than clicking through App Store Connect's per-locale tabs, and lets every store change land via normal PR review.
