App Store Connect MCP Integration

Core principle: When asc-mcp is configured, you can manage the entire App Store Connect workflow without leaving Claude Code — submit builds, distribute to TestFlight, respond to reviews, and monitor metrics programmatically.

Setup

Install

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

Create API Key

1. Open App Store Connect → Users and Access → Integrations → API
2. Generate key with Admin or App Manager role
3. Download the .p8 file (one-time download — save it securely)
4. Note the Key ID and Issuer ID

Add to Claude Code

claude mcp add asc-mcp \
  -e ASC_KEY_ID=YOUR_KEY_ID \
  -e ASC_ISSUER_ID=YOUR_ISSUER_ID \
  -e ASC_PRIVATE_KEY_PATH=/path/to/AuthKey.p8 \
  -- ~/.mint/bin/asc-mcp

Verify

Ask Claude to call company_current. If it returns your team name, you're connected.

Worker Filtering

asc-mcp has 25 workers (~208 tools). Loading all of them wastes context. Use --workers to load only what you need.

Presets

Preset	Workers	Tools	Use Case
TestFlight	apps,builds,beta_groups,beta_testers	~34	Beta distribution
Release	apps,builds,versions,reviews	~40	App Store submission
Monetization	apps,iap,subscriptions,offer_codes,pricing	~55	IAP and subscriptions
Full	(default, all workers)	~208	Everything

To use a preset, add --workers when registering the server:

claude mcp add asc-mcp \
  -e ASC_KEY_ID=... \
  -e ASC_ISSUER_ID=... \
  -e ASC_PRIVATE_KEY_PATH=... \
  -- ~/.mint/bin/asc-mcp --workers apps,builds,versions,reviews

Note: company and auth workers always load regardless of --workers. When builds is enabled, build_processing and build_beta are included automatically.

Worker Selection Decision Tree

digraph workers {
    "What are you doing?" [shape=diamond];
    "TestFlight preset" [shape=box, label="--workers apps,builds,\nbeta_groups,beta_testers"];
    "Release preset" [shape=box, label="--workers apps,builds,\nversions,reviews"];
    "Monetization preset" [shape=box, label="--workers apps,iap,\nsubscriptions,offer_codes,pricing"];
    "Full (no flag)" [shape=box, label="No --workers flag\n(all 208 tools)"];

    "What are you doing?" -> "TestFlight preset" [label="distributing beta builds"];
    "What are you doing?" -> "Release preset" [label="submitting to App Store"];
    "What are you doing?" -> "Monetization preset" [label="managing IAP/subscriptions"];
    "What are you doing?" -> "Full (no flag)" [label="multiple tasks or unsure"];
}

Workflow: Release Pipeline

Submit a new version to the App Store.

1. apps_search(query: "MyApp")           → get app ID
2. builds_list(appId, limit: 5)          → find latest processed build
3. app_versions_create(appId, platform: "IOS", versionString: "2.1.0")
4. app_versions_attach_build(versionId, buildId)
5. app_versions_set_review_details(versionId, { contactEmail, notes, ... })
6. app_versions_submit_for_review(versionId)
7. (After approval) app_versions_create_phased_release(versionId)

Before step 3: Version string must not already exist. Check with app_versions_list.

Before step 4: Build must be in VALID processing state. Check with builds_get_processing_state.

Before step 6: Version must be in PREPARE_FOR_SUBMISSION state. Attaching a build and setting review details are prerequisites.

---

Workflow: TestFlight Distribution

Distribute a build to beta testers.

1. apps_search(query: "MyApp")           → get app ID
2. builds_list(appId, limit: 5)          → find latest build
3. builds_set_beta_localization(buildId, locale: "en-US", whatsNew: "Bug fixes")
4. beta_groups_list(appId)               → find or create group
   OR beta_groups_create(appId, name: "Internal Testers", isInternal: true)
5. beta_groups_add_builds(groupId, [buildId])
6. builds_send_beta_notification(buildId) → notify testers (optional)

Tip: Internal testers (up to 100) get builds immediately. External testers (up to 10,000) require Beta App Review for the first build of each version.

---

Workflow: Review Management

Monitor and respond to App Store reviews.

1. apps_search(query: "MyApp")           → get app ID
2. reviews_list(appId, sort: "-createdDate", limit: 20)
   OR reviews_list(appId, filterRating: "1,2")  → negative reviews only
3. reviews_stats(appId)                  → rating distribution summary
4. reviews_create_response(reviewId, responseBody: "Thank you for...")

Response guidelines:

• Respond to negative reviews within 24-48 hours
• Be professional and offer specific help
• Updating a response replaces the previous one (users see "Developer Response")

---

Workflow: Feedback Triage

Correlate TestFlight feedback with build diagnostics.

1. builds_list(appId, limit: 10)         → recent builds
2. builds_get_beta_testers(buildId)      → who tested this build
3. metrics_build_diagnostics(buildId)    → crash signatures for this build
4. metrics_get_diagnostic_logs(signatureId) → individual crash logs

Limitation: TestFlight text feedback and screenshots are NOT available via the App Store Connect API. Use Xcode Organizer or the ASC web dashboard for feedback content.

---

Workflow: Multi-Company

Switch between App Store Connect teams.

1. company_list                          → see configured accounts
2. company_switch(companyId: "client-a") → switch active account
3. (All subsequent calls use client-a's credentials)

Multi-Company Setup

Add to ~/.config/asc-mcp/companies.json:

{
  "companies": [
    {
      "id": "my-company",
      "name": "My Company",
      "key_id": "KEY_ID_1",
      "issuer_id": "ISSUER_1",
      "key_path": "/Users/you/.keys/AuthKey1.p8"
    },
    {
      "id": "client-a",
      "name": "Client A",
      "key_id": "KEY_ID_2",
      "issuer_id": "ISSUER_2",
      "key_path": "/Users/you/.keys/AuthKey2.p8"
    }
  ]
}

Or use numbered environment variables: ASC_COMPANY_1_NAME, ASC_COMPANY_1_KEY_ID, etc.

---

API Constraints

Constraint	Details
No emoji in metadata	Version "What's New", descriptions, keywords — use words, not emoji
Version state	Only PREPARE_FOR_SUBMISSION versions are editable. Once submitted, create a new version to make changes.
JWT lifetime	20-minute tokens, auto-refreshed by asc-mcp
Rate limits	Apple enforces per-account limits. asc-mcp retries with exponential backoff on 429s.
Locale format	Standard codes: en-US, ja, de-DE, zh-Hans, ru
Build processing	Newly uploaded builds take 15-30 minutes to process. Poll builds_get_processing_state before attaching.
Phased release	Only available after approval. Can pause/resume with app_versions_update_phased_release.

---

Gotchas

Gotcha	Details
Build not found	Build may still be processing. Check builds_get_processing_state — must be VALID.
"Version already exists"	Can't create duplicate version strings. Use app_versions_list to check first.
Attach fails	Build must be processed AND the version must be in PREPARE_FOR_SUBMISSION.
Review details rejected	Contact info fields have format requirements. Email must be valid, phone must include country code.
Wrong app	apps_search is fuzzy. Verify the returned bundleId matches your target app.
Multi-company confusion	Always call company_current first to confirm which account is active before making changes.
Beta App Review	First external TestFlight build per version requires review. Subsequent builds to the same version are auto-approved.
Missing analytics	analytics_* tools require vendor_number in company config. Without it, sales/financial reports fail silently.

---

Anti-Rationalization

Thought	Reality
"I'll just use the ASC web dashboard"	MCP tools are faster for repetitive tasks — respond to 20 reviews, distribute to 5 groups, create versions across apps.
"I don't need worker filtering"	208 tools consume ~30K tokens of context. Filter to what you need.
"I'll submit without review details"	Submission will fail. app_versions_set_review_details is required before app_versions_submit_for_review.
"I'll skip company_current — I only have one account"	Multi-company configs persist between sessions. Always verify.
"Feedback triage is the same via API"	Text feedback and screenshots are NOT in the ASC API. Use Organizer for feedback content, MCP for crash diagnostics.

When asc-mcp is NOT Available

If asc-mcp is not configured, fall back to manual workflows:

• Crash analysis: Use Xcode Organizer (see axiom-testflight-triage) or App Store Connect web dashboard (see axiom-app-store-connect-ref)
• TestFlight distribution: Use Xcode → Product → Archive → Distribute, or xcodebuild + altool
• Review management: Use App Store Connect web dashboard
• Submission: Use Xcode → Product → Archive → Distribute to App Store
