App Store Connect MCP Server

Full control of App Store Connect from your coding agent. 40 tools: read intelligence that thinks, plus write/control that ships your app end to end (edit metadata, upload screenshots, attach builds, TestFlight, submit, release, even build and upload the binary locally). 6 slash-command workflows and a bundled Claude Skill. Not another API wrapper.

asc-mcp.pages.dev · npm · Pricing: free tier, Pro $9/mo

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
npx @pofky/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 40 opinionated tools, 6 slash-command Prompts, and a Claude Skill that all think. The read tools summarize and audit; the Pro control tools actually drive App Store Connect, from editing metadata to submitting and releasing, with the same API key. Two tools use MCP Sampling: your own client's model does the LLM work, so there is no extra cost from this server.

Why full control is possible without fastlane: fastlane's deliver and pilot are just calls to the same App Store Connect REST API this server authenticates against with your .p8. So nearly everything you would script with fastlane is a tool here, no Ruby toolchain required. The only step that needs your Mac is building and signing the binary, which build_and_archive and upload_binary drive via Xcode.

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

No global install needed if you prefer npx (see the manual config below).

Fastest setup (recommended). Drop your .p8 into Apple's standard path ~/.appstoreconnect/private_keys/ (the file is named AuthKey_XXXXXXXXXX.p8, and the Key ID is in the filename). Then run:

npx @pofky/asc-mcp init --write     # auto-detects the key, asks for your Issuer ID, and writes the config for you
# or: npx @pofky/asc-mcp init       # same, but prints the block to paste yourself

init --write finds your Claude Desktop / Claude Code config, backs it up, and merges in the server block, so there's no JSON editing. The
