App Store Connect MCP Server

The App Store Connect intelligence layer for your coding agent. 13 tools that think, 3 slash-command workflows, and a bundled Claude Skill. Not another API wrapper.

Maintained successor to JoshuaRileyDev/app-store-connect-mcp-server (archived Feb 2026). Different angle, same API surface plus more.

npm install -g @pofky/asc-mcp
asc-mcp install-skill   # one-line, optional, for auto-routed review questions

What Makes This Different

Other ASC MCP servers wrap the API and give you 80 to 293 raw endpoints. This one gives you 13 opinionated tools, 3 slash-command Prompts, and a Claude Skill that all think. Two of the tools use MCP Sampling: your own client's model does the LLM work, so there is no extra cost from this server.

You say	What happens
"Run a preflight check on my app"	Audits metadata, character limits, screenshots, build status. Catches the issues that cause 40% of rejections.
"Give me a morning briefing"	Summarizes all your apps: who's in review, who got rejected, new low-rating reviews, action items.
"Generate release notes from my git history"	Reads commits since last tag, categorizes them, and gives you structured data to write "What's New" text.
"List my apps"	Shows all your iOS/macOS apps with bundle IDs
"Is my app in review?"	Exact review state with context ("typical time: 24-48 hours")
"Show me 1-star reviews"	Customer reviews filtered by rating, territory, sorted by date
"What were my downloads this week?"	Sales and revenue summary by territory

No context switching. No portal. Just ask.

Setup (3 minutes)

Step 1. Create an API key in App Store Connect > Integrations > App Store Connect API (Admin or App Manager role), then grab three things from that same page:

• Issuer ID (ASC_ISSUER_ID): the UUID shown at the top of the page, with a copy button next to it.
• Key ID (ASC_KEY_ID): the 10-character ID next to your key, also in the filename AuthKey_XXXXXXXXXX.p8.
• .p8 file (ASC_PRIVATE_KEY_PATH): click Download and point this at the saved file. Apple lets you download it only once, so keep it safe.

Step 2. Install:

npm install -g @pofky/asc-mcp

Add to ~/.claude/settings.json (Claude Code) or your agent's MCP config:

{
  "mcpServers": {
    "appstore-connect": {
      "command": "asc-mcp",
      "env": {
        "ASC_KEY_ID": "YOUR_KEY_ID",
        "ASC_ISSUER_ID": "YOUR_ISSUER_ID",
        "ASC_PRIVATE_KEY_PATH": "~/.appstore/AuthKey_XXXX.p8"
      }
    }
  }
}

Step 3. Ask your agent: "List my App Store Connect apps"

Works with Claude Code, Cursor, Windsurf, Cline, and any MCP-compatible client.

Tools

Free (no account needed)

Tool	What it does
list_apps	List all your apps with name, bundle ID, SKU, platform
app_details	Version history, build status, release state, dates
review_status	Current review state with human-readable context

Pro ($9/mo)

Tool	What it does	Why it matters
list_reviews	Customer reviews filtered by rating, territory, sort order	See what users say without opening the portal
sales_report	Daily/weekly/monthly downloads and revenue by territory	Know your numbers instantly
release_preflight	Pre-submission audit: metadata, char limits, screenshots, builds	Catches 40%+ of common rejection causes before you submit
daily_briefing	Morning summary across all apps: status, reviews, rejections	One call replaces 10 minutes of portal clicking
release_notes	Git commits since last tag, categorized for writing "What's New"	Your AI agent writes release notes from your actual changes
keyword_insights	Analyze keywords against iTunes search competition, difficulty ratings	See which keywords are worth targeting at a glance
competitor_snapshot	Look up any app: ratings, reviews, version, price, release notes	Competitive intelligence without leaving your editor
metadata_diff	Compare live vs pending version metadata across all locales	Verify exactly what changed before submitting
triage_reviews	Pulls recent reviews and clusters them into 3 to 5 themes with counts, action buckets, and quotes, using MCP Sampling	Zero extra cost: your client's model does the clustering
draft_review_response	Drafts a public reply to a single review in the review's locale, via Sampling. Elicits tone if your client supports it. Never auto-posts.	Apple guideline 1.2 respected; you paste into ASC yourself

Coming next (Week 3): rejection-risk scoring against the 2026 corpus (guideline 2.3 metadata, 4.0 design, privacy-AI 5.1.2).

How Sampling works (zero extra cost)

triage_reviews and draft_review_response use the MCP Sampling primitive. When you call one of these tools, this server sends a sampling/createMessage request back to your own MCP client. Your client runs the LLM locally (Claude Desktop uses your account; Claude Code uses its session). We never call Anthropic from our side.

Outcome: review clustering and reply drafting cost you exactly what you would pay for any other Claude request, not a penny more from this server.

If your MCP client does not support Sampling yet, both tools return a structured degraded: true result with a clear explanation. Upgrade Claude Desktop or Claude Code to a recent version for full functionality.

Slash Commands (Prompts)

Type these in Claude Desktop or Claude Code and the agent runs a pre-built multi-tool workflow:

Slash command	What it does
/asc-weekly-review	Calls daily_briefing then list_reviews (low-rating, last 7 days) for every app, clusters themes, returns a single digest with 3-bullet action list.
/asc-rejection-audit	Given an app_id, calls release_preflight + metadata_diff + review_status, reads the result against the top 2026 rejection drivers (guideline 2.3 metadata, 4.0 design, privacy-AI 5.1.2). Produces Blocking / Likely-flagged / Safe sections.
/asc-release-go-no-go	Given an app_id, combines preflight + review queue + metadata diff + top competitors in the same category. Returns a direct GO or NO-GO with three supporting reasons.

These are MCP Prompts per the spec. Zero other App Store Connect MCP ships with them.

Claude Skill (one-line install)

After installing the MCP, run:

asc-mcp install-skill

This copies a small asc-review-triage Skill to ~/.claude/skills/ so Claude automatically picks up review-related questions ("any bad reviews lately?", "what do my users say?", "ratings this week?") and calls the right ASC tools without you having to explain the workflow each time.

Works on macOS, Linux, and Windows. To remove: asc-mcp uninstall-skill.
