appstore-mcp
An MCP server, written in Rust, that exposes the Apple App Store Connect API to AI agents. It covers the full product lifecycle — apps & metadata, in-app purchases, subscriptions and their offers, pricing & availability, App Store versions, App Review submission, TestFlight, provisioning & signing, asset uploads, promoted purchases, customer reviews, phased release, users & access, in-app events, Xcode Cloud, and analytics reports — across 113 tools, and can reach any other App Store Connect endpoint through two generic JSON:API tools.
Built on the official rmcp SDK over stdio.

Design: hybrid coverage
The App Store Connect API has hundreds of endpoints but is uniformly JSON:API. Rather than a tool per endpoint, this server is hybrid:
- Curated tools (111) for the common, multi-step, or error-prone workflows —
apps & metadata, IAPs, subscriptions & offers, versions, pricing, availability, App Review submission, TestFlight, provisioning, asset uploads, promoted purchases, customer reviews, phased release, users, in-app events, Xcode Cloud, analytics reports, and custom product pages.
- Two generic escape-hatch tools —
appstore_requestandappstore_list—
that can call any endpoint with raw JSON:API documents.

Install
Prebuilt binaries for macOS (universal), Linux (x86-64), and Windows (x86-64) are attached to every GitHub Release. Pick the channel for your client; all of them need credentials (see Credentials).
Claude Desktop — one-click bundle
Download appstore-mcp.mcpb from the latest release and open it with Claude Desktop (Settings → Extensions → Install Extension…, or drag the file onto the window). It prompts for your Issuer ID, Key ID, and .p8 key file. The bundle ships all three platforms' binaries and selects the right one automatically.
Claude Code — plugin marketplace
/plugin marketplace add forgeopslabs/appstore-mcp
/plugin install appstore-mcp@forgeopslabsThe plugin launches the appstore-mcp binary from your PATH, so install it first — download the binary for your OS from the latest release and put it on your PATH, or cargo install --git https://github.com/forgeopslabs/appstore-mcp. Set ASC_ISSUER_ID, ASC_KEY_ID, and ASC_PRIVATE_KEY_PATH in the environment you start Claude Code from.
Codex
Codex configures MCP servers directly (no marketplace). With appstore-mcp on your PATH:
codex mcp add appstore \
--env ASC_ISSUER_ID=... --env ASC_KEY_ID=... \
--env ASC_PRIVATE_KEY_PATH=/path/AuthKey_XXXXXX.p8 \
-- appstore-mcpor in ~/.codex/config.toml:
[mcp_servers.appstore]
command = "appstore-mcp"
args = []
env = { ASC_ISSUER_ID = "...", ASC_KEY_ID = "...", ASC_PRIVATE_KEY_PATH = "/path/AuthKey_XXXXXX.p8" }MCP Registry
Published as io.github.forgeopslabs/appstore-mcp (metadata in server.json) so any MCP-aware client can discover it.
From source
cargo build --release # -> target/release/appstore-mcpCredentials
Generate a Team Key in App Store Connect → Users and Access → Integrations → App Store Connect API, and download the .p8 file. Then set:
| Variable | Required | Description | |----------|----------|-------------| | ASC_ISSUER_ID | ✅ | Issuer UUID shown above the keys table. | | ASC_KEY_ID | ✅ | The API key's Key ID. | | ASC_PRIVATE_KEY | one of | Inline .p8 PEM contents. | | ASC_PRIVATE_KEY_PATH | one of | Path to the downloaded .p8 file. | | ASC_BASE_URL | optional | Override the API origin. | | ASC_LOG | optional | Log filter (to stderr). Default info. |
See .env.example. The server authenticates each request with a short-lived ES256 JWT signed by your key (cached and refreshed automatically).
The server starts even without credentials so a client can list its tools; tool calls then return an actionable configuration error until creds are set.
Build & run
cargo build --release
ASC_ISSUER_ID=... ASC_KEY_ID=... ASC_PRIVATE_KEY_PATH=/path/AuthKey_XXX.p8 \
./target/release/appstore-mcpThe server speaks MCP over stdio. Logs go to stderr; stdout is the protocol channel.
Use with an MCP client
Example client config (e.g. Claude Desktop's mcpServers):
{
"mcpServers": {
"appstore": {
"command": "/absolute/path/to/appstore-mcp/target/release/appstore-mcp",
"env": {
"ASC_ISSUER_ID": "00000000-0000-0000-0000-000000000000",
"ASC_KEY_ID": "ABCD123456",
"ASC_PRIVATE_KEY_PATH": "/absolute/path/to/AuthKey_ABCD123456.p8"
}
}
}
}Inspect with the MCP Inspector
npx @modelcontextprotocol/inspector ./target/release/appstore-mcpUsage notes
- IDs are opaque. List/get first to resolve app, IAP, subscription, set, and
price-point IDs, then pass them to create/update tools.
- Pricing needs a price point. Use
list_iap_price_points/
list_subscription_price_points to get the id for set_iap_price_schedule / set_subscription_price.
- Asset uploads (
upload_*) take a local file path and run the full reserve →
chunked upload → MD5 commit flow in one call. Screenshots/previews require an existing appScreenshotSet / appPreviewSet; create those with the generic tools if needed.
- Anything not listed is reachable via
appstore_request(raw method + path +
JSON:API body) or appstore_list (paginated GET). Example: appstore_request { "method": "GET", "path": "/v1/apps/123/customerReviews" }.
- Not covered: sales/finance report endpoints return gzipped TSV (not JSON:API)
and are out of scope for these tools.
Limitations (enforced by Apple)
- You cannot create an app via the API. The
appsresource only allows GET and
UPDATE — POST /v1/apps returns 403 FORBIDDEN_ERROR. Create the app record in the App Store Connect website (Apps → ➕ → New App); you can pre-create its bundle ID with create_bundle_id. All other tools operate on an existing app.
- A deleted in-app purchase's
productIdis permanently reserved by Apple and
cannot be reused.
Development
cargo test # unit tests (JWT signing, MD5, body builders)
cargo clippy --all-targets -- -D warnings
cargo fmt --checkRegenerate the tool reference after adding/changing tools (needs the release binary; no credentials required):
cargo build --release && python3 scripts/gen_tools_doc.py # rewrites docs/TOOLS.mdLive integration tests
scripts/integration_test.py drives the compiled server against the real API. Read-only by default; --write adds a self-cleaning IAP lifecycle.
cargo build --release
