appstoreconnect-codex-mcp

Compliant App Store Connect automation for Codex and other MCP clients.

This project exposes read-only App Store Connect tools through a stdio MCP server, plus a Fastify webhook API for signed App Store Connect webhook events. It only uses the official App Store Connect API and webhook notifications. It does not automate Apple ID web login, store Apple ID credentials, store browser cookies, or bypass 2FA.

What It Provides

• packages/asc-core: JWT signing, App Store Connect API client, pagination, error mapping, read-only service methods, webhook signature helpers, and write-operation guard logic.

• apps/asc-mcp-server: stdio MCP server exposing asc.* tools to Codex.

• apps/webhook-api: Fastify API with GET /healthz and signed POST /webhooks/app-store-connect.

• docs/COMPLIANCE.md: compliance boundaries and prohibited behavior.

• docs/OPERATIONS.md: deployment, secret, webhook, and troubleshooting notes.

• docs/CODEX_DESKTOP_INSTALL.md: local Codex Desktop MCP configuration.

MCP Tools

• asc.list_apps

• asc.get_app_status

• asc.list_app_versions

• asc.get_latest_version

• asc.list_builds

• asc.get_latest_build

• asc.list_review_submissions

• asc.get_beta_review_status

• asc.get_status_snapshot

Write tools are intentionally not registered in V1/V2. V3 write operations are represented only by guard interfaces and remain disabled by default.

Requirements

• Node.js 20+

• pnpm 10+

• App Store Connect API key with appropriate read permissions

Local Setup

pnpm install
cp .env.example .env
pnpm build
pnpm test

Provide either ASC_PRIVATE_KEY_PATH or ASC_PRIVATE_KEY_BASE64. Do not commit private keys, JWTs, webhook secrets, Apple ID credentials, cookies, or generated .env files.

Run

pnpm dev:mcp
pnpm dev:webhook

The webhook server listens on PORT or 3000 by default.

Codex Desktop

Add an MCP server entry to your Codex config:

[mcp_servers.app_store_connect]
command = "/path/to/node"
args = ["/path/to/appstoreconnect-codex-mcp/apps/asc-mcp-server/dist/index.js"]
startup_timeout_sec = 120

[mcp_servers.app_store_connect.env]
ASC_ISSUER_ID = "your-issuer-id"
ASC_KEY_ID = "your-key-id"
ASC_PRIVATE_KEY_PATH = "/secure/path/AuthKey_YOURKEYID.p8"
ASC_ENABLE_WRITE_TOOLS = "false"
ASC_REQUIRE_CONFIRMATION = "true"
ASC_ALLOWED_APP_IDS = ""
LOG_LEVEL = "warn"

Build before launching Codex:

pnpm build

More detail is in docs/CODEX_DESKTOP_INSTALL.md.

Compliance

This repository is designed around these rules:

• Use only official Apple App Store Connect API and webhook mechanisms.

• Do not simulate web login.

• Do not save Apple ID passwords, cookies, browser sessions, or 2FA tokens.

• Keep all write operations off by default.

• Require app allowlists, exact confirmation text, and audit logging before future write operations.

See docs/COMPLIANCE.md.
