App Store Connect MCPサーバー

---

Overview

asc-mcp is a Swift-based MCP server that connects a local macOS MCP client to the App Store Connect API. It exposes 537 tools across 34 App Store tool domains + 2 core domains, enabling you to automate iOS and macOS release workflows through natural language.

Configuration examples are included for Codex, Claude Code, Claude Desktop, Gemini CLI, VS Code with GitHub Copilot, Continue, Cursor, and Devin Desktop (formerly Windsurf). Client configuration is documented; release CI verifies installation, MCP initialization, and tool discovery on macOS rather than launching every third-party client.

New here? Follow the Quick Start. The remaining sections are reference material for advanced configuration, tool selection, and contributors.

Key capabilities

• Release and metadata — versions, localizations, builds, review submissions, phased rollout, and Xcode Cloud
• TestFlight and uploads — beta groups, testers, feedback, recruitment, build delivery, processing, and export compliance
• Monetization — in-app purchases, subscriptions, pricing, availability, offer codes, and promotional offers
• Marketing — screenshots, previews, custom product pages, product page optimization, and promoted purchases
• Accounts and provisioning — multiple App Store Connect teams, users, bundle IDs, devices, certificates, profiles, and capabilities
• Feedback and operations — customer reviews, webhooks, accessibility declarations, analytics, metrics, and diagnostics
• Safer automation — read-only mode, confirmation safeguards, strict pagination, and mutation recovery guidance
• Auditable API coverage — a versioned Apple OpenAPI contract and release-time drift checks

The source tree prepares 4.3.0; the installation examples below remain pinned to the last stable release until candidate acceptance and owner publication. See the migration guide for the separate Asset Library workflow.

Platform Support

asc-mcp is a local stdio server: the MCP client starts it on the same computer. A client being available on Linux or Windows does not make this Swift server cross-platform.

Environment	Status	Notes
macOS 15.6+ with Xcode 26.x	Recommended	Release CI specifically uses GitHub's macOS 15 runner with Xcode 26.2
macOS 14.0-15.5	Declared deployment target only	Build and runtime are unverified; a separately installed Swift 6.2+ toolchain may be needed
Linux	Not supported yet	Porting work and Linux CI are not complete
Windows	Not supported	Current source dependencies and Swift MCP stdio transport are not Windows-compatible

See Apple's Xcode system requirements for the macOS versions supported by each Xcode release.

Web and cloud sessions do not automatically inherit a local MCP configuration. Run the MCP client locally on a compatible Mac, or use a client feature that explicitly keeps execution on that Mac.

Quick Start

The recommended setup stores App Store Connect credentials once in a private local file. MCP clients then need only the path to the asc-mcp executable.

1. Install asc-mcp

brew install mint
mint install zelentsov-dev/asc-mcp@v4.3.0
~/.mint/bin/asc-mcp --version

2. Create an App Store Connect API key

1. Open App Store Connect → Users and Access → Integrations → Team Keys.
2. Generate a key with the least-privileged role that covers your workflow. App Manager or Admin is needed only when the corresponding operations require it.
3. Download the .p8 file. Apple allows it to be downloaded only once.
4. Copy the Key ID and Issuer ID.

3. Save the credentials locally

Create private configuration directories, then move the downloaded .p8 file into ~/.keys/. Replace the source path and filename in the second command:

mkdir -p ~/.config/asc-mcp ~/.keys
chmod 700 ~/.config/asc-mcp ~/.keys
mv /path/to/downloaded/AuthKey_XXXXXXXXXX.p8 ~/.keys/

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"
    }
  ]
}

Replace /Users/you with your actual home-directory path. Keep both files outside the repository and restrict access:

chmod 600 ~/.config/asc-mcp/companies.json
chmod 600 /Users/you/.keys/AuthKey_XXXXXXXXXX.p8

[!CAUTION] Never commit companies.json, a .p8 key, or raw credentials to Git. Revoke the App Store Connect key immediately if it is exposed.

4. Connect your MCP client

Choose one client. You do not need to configure every client.

Codex

codex mcp add asc-mcp -- ~/.mint/bin/asc-mcp
codex mcp list

Claude Code

claude mcp add \
  --transport stdio \
  --scope user \
  asc-mcp \
  -- ~/.mint/bin/asc-mcp

claude mcp get asc-mcp
claude mcp list

For Claude Desktop, Gemini CLI, VS Code, Continue, Cursor, and Devin Desktop, use the ready-to-copy examples in MCP Client Setup.

5. Try it

Restart a GUI client after changing its configuration, open its MCP tool list, and ask:

List my App Store Connect apps.

If the connection or request fails, see Troubleshooting.

Installation

Mint on macOS (recommended)

Mint installs the pinned release from source and keeps the executable at ~/.mint/bin/asc-mcp.

brew install mint
mint install zelentsov-dev/asc-mcp@v4.3.0

Update or reinstall the pinned release:

mint install zelentsov-dev/asc-mcp@v4.3.0 --force

Stable users should install a version tag. Installing main or develop is intended only for maintainers and pre-release testing.

Build from source

Use Xcode 26.x on a compatible macOS version, or install a standalone Swift 6.2+ toolchain.

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

The executable is .build/release/asc-mcp. If you copy it elsewhere, also copy the adjacent resource bundle:

cp .build/release/asc-mcp /usr/local/bin/asc-mcp
cp -R .build/release/asc-mcp_asc-mcp.bundle /usr/local/bin/

The bundle contains the versioned OpenAPI operation contract used by release checks.

Upgrading from an older release

Version 4.1 keeps every existing tool name, required input, projection key, and array shape. Xcode Cloud read tools now reject undocumented arguments and validate returned links, paging, relationship lineage, and included resources more strictly. New *Present projection fields distinguish Apple-omitted arrays from present empty arrays while legacy array fields remain arrays. Newly exposed nested *_limit inputs must be paired with their matching include value, and continuation calls must repeat the original request scope unchanged. The new product and workflow delete tools default to a safe preview and require the latest preview receipt plus exact inventory confirmation before permanent deletion.

Version 4 keeps every existing tool name and worker filter, but destructive Marketing and review-attachment calls now require an exact confirmation ID before any Apple request:

Existing tool	New required confirmation
custom_pages_delete	confirm_page_id
ppo_delete_experiment	confirm_experiment_id
promoted_delete	confirm_promoted_purchase_id
review_attachments_delete	confirm_attachment_id
screenshots_delete_set, screenshots_delete_preview_set	confirm_set_id
screenshots_delete	confirm_screenshot_id
screenshots_delete_preview	confirm_preview_id

ppo_update_experiment also requires confirm_experiment_id when state is supplied. Calls that update only name or traffic proportion remain unchanged. After an unknown or committed_unverified mutation result, use the returned inspection action before retrying.

Remove undocumented top-level arguments from existing Marketing and review-attachment calls. Version 4 rejects unknown keys before any network request instead of silently ignoring them.

Configuration

Credentials

The default ~/.config/asc-mcp/companies.json file shown in the Quick Start is recommended because it works consistently for terminal and GUI clients without duplicating secrets in every client configuration.

For multiple companies, add more entries:

{
  "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 Company",
      "key_id": "YYYYYYYYYY",
      "issuer_id": "yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy",
      "key_path": "/Users/you/.keys/AuthKey_YYYYYYYYYY.p8"
    }
  ]
}

vendor_number is required only for analytics_sales_report, analytics_financial_report, and analytics_app_summary. Find it in App Store Connect → Sales and Trends → Reports.

Environment variables are useful for automation, but GUI apps launched from Finder may not inherit your shell environment. The file-based setup above is simpler for most users.

Single company:

export ASC_KEY_ID=XXXXXXXXXX
export ASC_ISSUER_ID=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
export ASC_PRIVATE_KEY_PATH=/Users/you/.keys/AuthKey_XXXXXXXXXX.p8
export ASC_COMPANY_NAME="My Company"                 # optional
export ASC_VENDOR_NUMBER=YOUR_VENDOR_NUMBER          # optional, analytics only

Multiple companies:

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=/Users/you/.keys/AuthKey_XXXXXXXXXX.p8

export ASC_COMPANY_2_NAME="Client Company"
export ASC_COMPANY_2_KEY_ID=YYYYYYYYYY
export ASC_COMPANY_2_ISSUER_ID=yyyyyyyy-yyyy-yyyy-yyyy-yyyyyyyyyyyy
export ASC_COMPANY_2_KEY_PATH=/Users/you/.keys/AuthKey_YYYYYYYYYY.p8

Numbering starts at 1. Each consecutive entry must provide both ASC_COMPANY_{N}_KEY_ID and ASC_COMPANY_{N}_ISSUER_ID; scanning stops at the first missing pair.

The server resolves credentials in this order:

1. --companies /absolute/path/to/companies.json
2. Constructor parameter for programmatic embedding
3. ASC_MCP_COMPANIES=/absolute/path/to/companies.json
4. Default configuration file locations, including ~/.config/asc-mcp/companies.json
5. ASC_COMPANY_1_KEY_ID and the other numbered multi-company variables
6. ASC_KEY_ID, ASC_ISSUER_ID, and a private-key variable for one company

MCP Client Setup

All examples below assume a Mint installation and the recommended companies.json credential file. Replace /Users/you with your actual home-directory path. GUI clients generally require an absolute executable path.

Client	Configuration scope	Notes
Codex	User config by CLI; optional trusted-project config	Shared by local Codex clients on the same Mac
Claude Code	user, local, or project scope	user is simplest for a personal App Store utility
Claude Desktop	User-level desktop config	Restart after editing
Gemini CLI	User settings	Local stdio server
VS Code with GitHub Copilot	User profile or .vscode/mcp.json	Confirm server trust on first start
Continue	Workspace .continue/mcpServers/	Separate from native VS Code MCP configuration
Cursor	User or project mcp.json	Use an absolute command path
Devin Desktop (formerly Windsurf)	User MCP config	Keep no more than 100 active tools

Recommended CLI registration:

codex mcp add asc-mcp -- ~/.mint/bin/asc-mcp
codex mcp list
codex mcp get asc-mcp --json

The same local MCP configuration is shared by Codex clients on that Mac. The user configuration is $CODEX_HOME/config.toml, which defaults to ~/.codex/config.toml:

[mcp_servers.asc-mcp]
command = "/Users/you/.mint/bin/asc-mcp"
startup_timeout_sec = 20
tool_timeout_sec = 60
enabled = true

For a project-specific setup, place the same table in .codex/config.toml; Codex loads project configuration only after the project is trusted. If you use shell credentials instead of companies.json, explicitly forward them:

env_vars = ["ASC_KEY_ID", "ASC_ISSUER_ID", "ASC_PRIVATE_KEY_PATH"]

Restart a GUI client after changing the configuration, then use its MCP view or /mcp to confirm that asc-mcp is active. See the official Codex MCP documentation.

Register once for all local projects:

claude mcp add \
  --transport stdio \
  --scope user \
  asc-mcp \
  -- ~/.mint/bin/asc-mcp

claude mcp get asc-mcp
claude mcp list

Use --scope local for only the current project or --scope project to create a shared .mcp.json. Project servers require trust approval. Never place raw App Store Connect credentials in a committed .mcp.json.

Claude stores user and local MCP entries in ~/.claude.json; .claude/settings.json is not the global MCP registry. Use /mcp inside Claude Code to inspect or reconnect the server. See the official Claude Code MCP documentation.

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

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/Users/you/.mint/bin/asc-mcp"
    }
  }
}

Quit and reopen Claude Desktop after saving the file.

Add the server to ~/.gemini/settings.json:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/Users/you/.mint/bin/asc-mcp"
    }
  }
}

The default Gemini MCP timeout is intentionally retained. See the official Gemini CLI MCP documentation.

Run MCP: Add Server from the Command Palette and choose the user profile for a personal setup. For a workspace setup, create .vscode/mcp.json:

{
  "servers": {
    "asc-mcp": {
      "type": "stdio",
      "command": "/Users/you/.mint/bin/asc-mcp"
    }
  }
}

Confirm that you trust the local server when VS Code first starts it. Do not commit user-specific paths or secrets in a shared workspace file. See the official VS Code MCP documentation.

Continue does not use .vscode/mcp.json. Create .continue/mcpServers/asc-mcp.json in the workspace:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/Users/you/.mint/bin/asc-mcp"
    }
  }
}

MCP tools are available in Continue agent mode. See the official Continue MCP documentation.

Use ~/.cursor/mcp.json for all projects or .cursor/mcp.json for one project:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/Users/you/.mint/bin/asc-mcp"
    }
  }
}

Restart or refresh the MCP server from Cursor settings after editing the file. See the official Cursor MCP documentation.

Add the server to ~/.codeium/windsurf/mcp_config.json. This example enables a 72-tool release subset, below Cascade's 100-tool limit:

{
  "mcpServers": {
    "asc-mcp": {
      "command": "/Users/you/.mint/bin/asc-mcp",
      "args": [
        "--workers",
        "apps,builds,export_compliance,versions,reviews"
      ]
    }
  }
}

You can also disable individual tools in the client. Server-side worker filtering is recommended because it keeps the active catalog predictable. See the official Devin Desktop MCP documentation.

[!IMPORTANT] command must point to the real executable. GUI clients often do not inherit shell aliases, PATH changes, or environment variables. Use an absolute path and prefer the default companies.json credential file.

Worker Filtering

The server exposes 537 tools across 34 App Store tool domains + 2 core domains. Some MCP clients impose a tool limit; Cascade in Devin Desktop currently allows 100 active tools. Use the 36 --workers filter keys to enable only the workers you need:

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

# App Store release preparation subset (99 tools, including always-on and build sub-workers)
asc-mcp --workers apps,accessibility,builds,export_compliance,versions,app_info,screenshots

# TestFlight review helpers can be loaded separately (49 tools)
asc-mcp --workers apps,builds,beta_app,pre_release

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

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.

Read-Only Mode

Use --read-only when you want safe inspection without App Store Connect mutations:

asc-mcp --read-only
asc-mcp --read-only --workers apps,builds,reviews,analytics

In this mode, read tools such as *_list, *_get, *_search, *_status, *_verify, *_parse, *_triage, auth_*, analytics, and metrics remain available. Tools that can create, update, upload, submit, release, delete, revoke, clear, cancel, or otherwise mutate App Store Connect are blocked before their worker handler runs. company_switch remains available because it changes only the local active company context.
