The App Stores Cooolest API
Forget Fastlane, this is the app stores coolest API.
Install
Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).
smbcloud-ascapi-cliEnvironment variables
ASC_API_KEYrequired App Store Connect API key ID (Users and Access → Integrations → App Store Connect API).ASC_ISSUER_IDrequired App Store Connect API issuer ID, shown on the same page as the key.ASC_PRIVATE_KEY_PATHsecret Path to the .p8 private key for that API key. Defaults to ~/.appstoreconnect/private_keys/AuthKey_<key-id>.p8, matching Xcode's own convention.

smbcloud-ascapi
smbcloud-ascapi is the app stores coolest API.
Eight crates, split by domain and layered so neither front end can drift from the other:
| Crate | What it is |
|---|---|
smbcloud-ascapi-core | Shared transport: JWT auth, the HTTP client, JSON:API envelopes, error types |
smbcloud-ascapi-aso | App Metadata: apps, app infos, versions, builds, pre-release versions, review submissions, bundle IDs, localizations, screenshots |
smbcloud-ascapi-pricing | Pricing: app price schedules, and the per-territory prices joined with their price points and currencies |
smbcloud-ascapi-signing | Code signing: certificates and provisioning profiles, plus local RSA key pair and CSR generation |
smbcloud-ascapi-reports | Sales reports: account-level sales data, as Apple's gzip-compressed TSV |
smbcloud-ascapi-frontend | Operations both surfaces share, so the CLI and the MCP server agree by construction, plus the CLI's xcrun altool upload |
smbcloud-ascapi-mcp | The MCP contract and stdio server |
smbcloud-ascapi-cli | The asc binary: clap command tree, plus --mcp |
aso, pricing, signing and reports know nothing about each other, and neither knows
anything about the front ends. Each adds its calls to
smbcloud_ascapi_core::Client as extension traits, since Rust only
allows inherent impls in the crate that defines a type:
use smbcloud_ascapi_core::{ApiKey, Client};
use smbcloud_ascapi_aso::prelude::*; // or pricing::prelude, signing::preludeMCP Registry name: mcp-name: io.github.smbcloudXYZ/ascapi
Credentials
The CLI signs requests with an App Store Connect API key:
| Flag | Environment variable | Notes |
|---|---|---|
--key-id | ASC_API_KEY | The key id. There is no ASC_KEY_ID. |
--issuer-id | ASC_ISSUER_ID | The issuer id from App Store Connect. |
--private-key-path | ASC_PRIVATE_KEY_PATH | Defaults to ~/.appstoreconnect/private_keys/AuthKey_<key-id>.p8. |
With --mcp, credentials are resolved on each tool call, so the server can
list its tools before they are configured.
