asc-mcp

Everything else(Claude Code, Cursor, Windsurf, Cline), one command:

npx @pofky/asc-mcp init --write # finds your .p8, asks for your Issuer ID, writes your MCP config

No context switching. No portal. Just ask.

Other ASC MCP servers wrap the API and give you 80 to 982 raw endpoints. This one gives you 41 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'sdeliverandpilotare 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, whichbuild_and_archiveandupload_binarydrive via Xcode.

- 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 filenameAuthKey_XXXXXXXXXX.p8.
- .p8file(ASC_PRIVATE_KEY_PATH): clickDownloadand point this at the saved file. Apple lets you download it only once, so keep it safe.

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

Fastest setup (recommended).Drop your.p8into Apple's standard path~/.appstoreconnect/private_keys/(the file is namedAuthKey_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 --writefinds your Claude Desktop / Claude Code config, backs it up, and merges in the server block, so there's no JSON editing. The server also auto-discovers the.p8path at runtime, so you only ever needASC_ISSUER_ID(andASC_LICENSE_KEYfor Pro).

Stuck?Runnpx @pofky/asc-mcp doctor(or ask your agent to callasc_setup_check). It checks your key, Issuer ID, a live connection to App Store Connect, and your license, and prints the exact fix for anything wrong. In your agent, the/asc-startcommand walks a first-time user through all of this.

Manual setup.Add to your agent's MCP config (Claude Desktop config, or~/.claude.jsonfor Claude Code). Usenpxfor zero-install, orasc-mcpif you installed globally:

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

These tools write to App Store Connect. Every outward-facing action (submit, release, upload binary) requires an explicitconfirm: true, so nothing leaves your machine by accident.

The whole flow chains:setup_app_store_signingtobuild_and_archivetoupload_binarytowait_for_build(blocks until VALID) toattach_buildtoupdate_version_metadatatoupload_screenshotstoset_app_metadata/set_app_price/set_app_availability/set_age_rating/set_review_contacttorelease_preflighttosubmit_for_reviewtorelease_version. The/asc-ship-releaseslash command drives it for you.

release_preflightis the single source of truth for "is this submittable": it checks every API-addressable field and ends with a tailored "Manual steps to finish" list for the few things Apple only allows in the website (first-IAP bundling, App Privacy nutrition labels, EU trader status).

- Create an app record / App Group.POST /v1/appsis forbidden for API keys; do it once in the website.
- App Privacy nutrition label.Not in the API.set_privacy_nutritionreturns the checklist plus a deep link.
- EU DSA trader status.Not in the API.set_eu_trader_statusreturns the steps. Legal decision.
- An app's first IAPs/subscriptions.Must be submitted with the version in the website;submit_for_reviewaborts rather than orphan the version. Later products submit via the API.
- Certificate creation / cloud signing.Least-privilege keys can't;setup_app_store_signinguses manual-signing profiles instead.
- Compiling the binary.Needs Xcode on your Mac (build_and_archiveruns it locally).
- Posting a public review reply.draft_review_responsewrites it; you paste it in the website.

triage_reviewsanddraft_review_responseuse the MCP Sampling primitive. When you call one of these tools, this server sends asampling/createMessagerequest 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 structureddegraded: trueresult with a clear explanation. Upgrade Claude Desktop or Claude Code to a recent version for full functionality.

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

This copies a smallasc-review-triageSkill 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:npx @pofky/asc-mcp uninstall-skill.
