A Model Context Protocol server for the App Store Connect API.
Manage apps, builds, TestFlight, reviews, and more — directly from Claude.

Works with:

Overview

asc-mcp is a Swift-based MCP server that bridges Claude (or any MCP-compatible host) with the App Store Connect API. It exposes 208 tools across 25 workers, enabling you to automate your entire iOS/macOS release workflow through natural language.

Key capabilities

Multi-account — manage multiple App Store Connect teams from a single server
Full release pipeline — create versions, attach builds, submit for review, phased rollout
TestFlight automation — beta groups, testers, build distribution, localized What's New
Build management — track processing, encryption compliance, readiness checks
Customer reviews — list, respond, update, delete responses, aggregate statistics
In-app purchases — CRUD for IAPs, localizations, price points, review screenshots
Subscriptions — subscription CRUD, groups, localizations, prices, offer codes, win-back offers
Provisioning — bundle IDs, devices, certificates, profiles, capabilities
Marketing — screenshots, app previews, custom product pages, A/B testing (PPO), promoted purchases
Analytics & Metrics — sales/financial reports, analytics reports, performance metrics, diagnostics
Metadata management — localized descriptions, keywords, What's New across all locales

Quick Start

# 1. Install via Mint
brew install mint
mint install zelentsov-dev/asc-mcp@1.4.0

# 2. Add to Claude Code with env vars (simplest setup)
claude mcp add asc-mcp \
  -e ASC_KEY_ID=XXXXXXXXXX \
  -e ASC_ISSUER_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \
  -e ASC_PRIVATE_KEY_PATH=/path/to/AuthKey.p8 \
  -- ~/.mint/bin/asc-mcp

Or use a JSON config file — see Configuration below.

Prerequisites

Requirement	Version
macOS	14.0+ (Sonoma)
Swift	6.2+
Xcode	16.0+ (for building)
App Store Connect API Key	Create one here

Installation

Option A: Mint (recommended)

Mint is the simplest way to install — one command, no manual cloning.

# Install Mint (if you don't have it)
brew install mint

# Install asc-mcp from GitHub
mint install zelentsov-dev/asc-mcp@1.4.0

# Register in Claude Code
claude mcp add asc-mcp -- ~/.mint/bin/asc-mcp

To install a specific branch or tag:

mint install zelentsov-dev/asc-mcp@main      # main branch
mint install zelentsov-dev/asc-mcp@develop    # develop branch
mint install zelentsov-dev/asc-mcp@1.4.0      # specific tag

To update to the latest version:

mint install zelentsov-dev/asc-mcp@1.4.0 --force

Option B: Build from Source

git clone https://github.com/zelentsov-dev/asc-mcp.git
cd asc-mcp
swift build -c release

# Register in Claude Code
claude mcp add asc-mcp -- $(pwd)/.build/release/asc-mcp

Tip

For convenience, copy the binary to a location in your PATH:

cp .build/release/asc-mcp /usr/local/bin/asc-mcp

Configuration

1. App Store Connect API Key

Go to App Store Connect → Users and Access → Integrations → Team Keys
Click Generate API Key — select appropriate role (Admin or App Manager recommended)
Download the .p8 private key file (you can only download it once!)
Note the Key ID and Issuer ID

2. Companies Configuration

asc-mcp supports three configuration methods (checked in this order):

Option A: Environment Variables (recommended for MCP clients)

Single company — simplest setup:

export ASC_KEY_ID=XXXXXXXXXX
export ASC_ISSUER_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export ASC_PRIVATE_KEY_PATH=/path/to/AuthKey.p8
# or pass the key content directly:
# export ASC_PRIVATE_KEY="-----BEGIN PRIVATE KEY-----\nMIGT..."
# optional:
# export ASC_COMPANY_NAME="My Company"
# export ASC_VENDOR_NUMBER=YOUR_VENDOR_NUMBER          # for analytics

Multiple companies — numbered variables:

export ASC_COMPANY_1_NAME="My Company"
export ASC_COMPANY_1_KEY_ID=XXXXXXXXXX
export ASC_COMPANY_1_ISSUER_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export ASC_COMPANY_1_KEY_PATH=/path/to/AuthKey1.p8
export ASC_COMPANY_1_VENDOR_NUMBER=YOUR_VENDOR_NUMBER   # optional, for analytics

export ASC_COMPANY_2_NAME="Client Corp"
export ASC_COMPANY_2_KEY_ID=YYYYYYYYYY
export ASC_COMPANY_2_ISSUER_ID=yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy
export ASC_COMPANY_2_KEY_PATH=/path/to/AuthKey2.p8

Numbering starts at 1. The server scans while ASC_COMPANY_{N}_KEY_ID exists.

Option B: JSON Config File

Create ~/.config/asc-mcp/companies.json:

{
  "companies": [
    {
      "id": "my-company",
      "name": "My Company",
      "key_id": "XXXXXXXXXX",
      "issuer_id": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      "key_path": "/Users/you/.keys/AuthKey_XXXXXXXXXX.p8",
      "vendor_number": "YOUR_VENDOR_NUMBER"
    },
    {
      "id": "client-company",
      "name": "Client Corp",
      "key_id": "YYYYYYYYYY",
      "issuer_id": "yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy",
      "key_path": "/Users/you/.keys/AuthKey_YYYYYYYYYY.p8",
      "vendor_number": "YOUR_VENDOR_NUMBER"
    }
  ]
}

Note: vendor_number is required for analytics tools (analytics_sales_report, analytics_financial_report, analytics_app_summary). Find it in App Store Connect → Sales and Trends → Reports.

Configuration Priority

The server resolves configuration in this order:

--companies /path/to/companies.json (CLI argument)
Constructor parameter (programmatic)
ASC_MCP_COMPANIES=/path/to/companies.json (env var pointing to JSON file)
Default JSON file paths (~/.config/asc-mcp/companies.json, etc.)
ASC_COMPANY_1_KEY_ID ... (multi-company env vars)
ASC_KEY_ID + ASC_ISSUER_ID (single-company env vars)

3. MCP Host Configuration

claude mcp add asc-mcp -- ~/.mint/bin/asc-mcp

Or add to .mcp.json (project) / .claude/settings.json (global) with env vars:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/path/to/asc-mcp",
      "env": {
        "ASC_KEY_ID": "XXXXXXXXXX",
        "ASC_ISSUER_ID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "ASC_PRIVATE_KEY_PATH": "/path/to/AuthKey.p8"
      }
    }
  }
}

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/path/to/asc-mcp",
      "env": {
        "ASC_KEY_ID": "XXXXXXXXXX",
        "ASC_ISSUER_ID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "ASC_PRIVATE_KEY_PATH": "/path/to/AuthKey.p8"
      }
    }
  }
}

Codex CLI

Add to ~/.codex/config.toml:

[mcp_servers.asc-mcp]
command = "/path/to/asc-mcp"
startup_timeout_sec = 20
tool_timeout_sec = 60
enabled = true

Set env vars in your shell or use a wrapper script.

Gemini CLI

Add to ~/.gemini/settings.json:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/path/to/asc-mcp",
      "timeout": 60000,
      "env": {
        "ASC_KEY_ID": "XXXXXXXXXX",
        "ASC_ISSUER_ID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "ASC_PRIVATE_KEY_PATH": "/path/to/AuthKey.p8"
      }
    }
  }
}

VS Code (Copilot / Continue)

Add to .vscode/mcp.json:

{
  "servers": {
    "asc-mcp": {
      "command": "/path/to/asc-mcp",
      "env": {
        "ASC_KEY_ID": "XXXXXXXXXX",
        "ASC_ISSUER_ID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "ASC_PRIVATE_KEY_PATH": "/path/to/AuthKey.p8"
      }
    }
  }
}

Cursor

Add to Cursor settings → MCP Servers:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/path/to/asc-mcp",
      "env": {
        "ASC_KEY_ID": "XXXXXXXXXX",
        "ASC_ISSUER_ID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "ASC_PRIVATE_KEY_PATH": "/path/to/AuthKey.p8"
      }
    }
  }
}

Windsurf

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/path/to/asc-mcp",
      "args": ["--workers", "apps,builds,versions,reviews,beta_groups,iap"],
      "env": {
        "ASC_KEY_ID": "XXXXXXXXXX",
        "ASC_ISSUER_ID": "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
        "ASC_PRIVATE_KEY_PATH": "/path/to/AuthKey.p8"
      }
    }
  }
}

Note: Windsurf has a 100-tool limit. The server exposes ~109 tools by default, so you must use --workers to select a subset. See Worker Filtering below.

Important

If the MCP host doesn't inherit your shell PATH, you may need to specify the full path to the binary and ensure .p8 key paths are absolute.

Worker Filtering

The server exposes 208 tools across 25 workers. Some MCP clients impose a tool limit (e.g., Windsurf caps at 100). Use --workers to enable only the workers you need:

# Only load apps, builds, and version lifecycle tools
asc-mcp --workers apps,builds,versions

# Full release workflow subset (~60 tools, fits within any client limit)
asc-mcp --workers apps,builds,versions,reviews,beta_groups,iap

# Monetization focus
asc-mcp --workers apps,iap,subscriptions,offer_codes,winback,pricing,promoted

company and auth workers are always enabled regardless of the filter (they provide core multi-account and authentication functionality).

When builds is enabled, it automatically includes build_processing and build_beta sub-workers.

Available worker names:

Worker	Prefix	Tools	Description
`apps`	`apps_`	9	App listing, metadata, localizations
`builds`	`builds_`	4	Build management
`build_processing`	`builds_*_processing_`	4	Build states, encryption

Token Cost

When connected to an LLM client, tool definitions consume context tokens. Here's the approximate footprint:

Configuration	Tools	~Tokens
All workers (default)	208	~24,000
Release workflow: `apps,builds,versions,reviews`	~40	~5,500
Monetization: `apps,iap,subscriptions,pricing`	~54	~6,500
TestFlight: `apps,builds,beta_groups,beta_testers`	~34	~4,500
Marketing: `apps,screenshots,custom_pages,ppo,promoted`	~46	~5,800
`--workers apps`	16	~1,850

Heaviest workers: Provisioning (17 tools), InAppPurchases (17 tools), Subscriptions (15 tools), AppLifecycle (13 tools), Screenshots (12 tools).

For Claude (200K context) ~22K tokens is ~5–7% — negligible. For clients with smaller context windows, use --workers to reduce the footprint.

Design Principles

Swift 6 strict concurrency — all workers and services are Sendable, proper actor isolation
Actor-based HTTP client — thread-safe with exponential backoff and retry logic
Prefix-based routing — WorkerManager routes tool calls by name prefix (zero config)
Minimal dependencies — only the MCP Swift SDK

Troubleshooting

Server not responding / MCP disconnection

Verify the binary path is correct in your MCP host config
Check that companies.json exists and is valid JSON
Ensure .p8 key file paths are absolute and the files exist
Try running the binary directly to see error output: .build/release/asc-mcp

Authentication errors (401)

Verify your Key ID and Issuer ID match what's shown in App Store Connect
Ensure the .p8 file is the original download (not modified)
Check that the API key hasn't been revoked
JWT tokens auto-refresh, but if the key is invalid, all requests will fail

"Version must be in PREPARE_FOR_SUBMISSION state"

You can only edit metadata for versions that are in PREPARE_FOR_SUBMISSION state. Versions in READY_FOR_SALE, IN_REVIEW, or WAITING_FOR_REVIEW are read-only. Create a new version first if needed.

Build processing takes too long

Use builds_wait_for_processing with a reasonable timeout (default 1800s). Apple's build processing typically takes 5–30 minutes but can be longer during peak times.

Rate limiting (429 errors)

The HTTP client automatically retries with exponential backoff on 429 responses. If you consistently hit limits, reduce the frequency of API calls or use pagination with smaller page sizes.

Development

Building

swift build              # Debug build
swift build -c release   # Release build (optimized)
swift package clean      # Clean build artifacts

Test Mode

.build/debug/asc-mcp --test    # Runs built-in integration tests

Adding a New Tool

Create handler method in the appropriate Worker+Handlers.swift
Add tool definition in Worker+ToolDefinitions.swift
Register in worker's getTools() method
Add routing case in worker's handleTool() switch
The WorkerManager auto-routes by prefix — no changes needed there

Adding a New Worker

Create directory: Workers/MyWorker/
Create 3 files: MyWorker.swift, MyWorker+ToolDefinitions.swift, MyWorker+Handlers.swift
Add worker property and initialization in WorkerManager.swift
Add routing rule in WorkerManager.registerWorkers()
Add getMyTools() helper method
