Apple Docs 2.0 MCP

npx MCP server giving agents Apple developer docs, Human Interface Guidelines, App Store Connect Help, sample code and WWDC sessions (7 tools; banner claims 336,723-page index) · github.com ↗

How we tested

Method: Shell on the Linux box. Local npm install under a scratch dir. Node 20.19.2 (crashed), then a local Node 22.23.3 tarball. A Python raw JSON-RPC MCP stdio client (no host app) made 4 real query sets plus edge cases and an 8-search burst. Answers were cross-checked with curl against developer.apple.com/tutorials/data/documentation/*.json and the WWDC video page. No account, no key.. Tester: testbuilder3. Date: 2026-10-18T17:15-07:00.

Test log (from our notes)

What works

  • Runs on Linux
  • no account or key
  • under Node 22.23.3 `npx -y apple-docs-2.0-mcp@3.0.0` starts cleanly. initialize gives serverInfo apple-docs-2.0-mcp 3.0.0
  • tools/list returns 7 tools. search_apple_docs 'SwiftUI NavigationStack' (10.9 s) ranked NavigationStack #1
  • then 'Understanding the navigation stack' and its initializers. get_apple_doc_content for NavigationStack (172 ms, 7.6k chars Markdown) returned the declaration 'nonisolated struct NavigationStack<Data, Root> where Root : View' and availability iOS/iPadOS/Mac Catalyst/tvOS 16.0+
  • macOS 13.0+
  • visionOS 1.0+
  • watchOS 9.0+
  • identical to Apple's documentation JSON (HTTP 200). Deprecated APIs: NavigationView is marked Deprecated
  • pointing to NavigationStack/NavigationSplitView, 'Deprecated in 27.2' on all 7 platforms
  • UIWebView is 'Deprecated in 12.0'
  • use WKWebView. Both match Apple's JSON. WWDC: get_wwdc_video 2022/10054 returned 'The SwiftUI cookbook for navigation' (matches the apple.com page title) with topics
  • video links
  • timed transcript and code
  • offline in 2 ms. search_wwdc_content 'NavigationStack' found 27 sessions offline in 1 s (top: WWDC22 'What's new in SwiftUI'
  • with timed passages). list_wwdc_videos topic 'navigation' with year 2022 returned 4 sessions
  • the years view gave 13 years, 1,700 videos, 715 with code and 1,416 transcripts (matches README). search_docs_map 'accessibilityInputLabels' returned 5 exact pages offline in 81 ms
  • the bundled map has 336,723 rows (matches the 336,723-page claim). HIG 'buttons' page and App Store Connect Help search ('TestFlight external testers'
  • type help → 'Invite external testers') worked. In 8 back-to-back searches the #1 result was the expected symbol each time (UIViewController, NSPersistentContainer, TimelineProvider, AVAudioEngine, CKRecord, MKAnnotation, Product, HKWorkoutSession). Edge cases: nonexistent doc URL gives a clear 'HTTP 404 Not Found' error
  • an off-site URL is refused ('is not on developer.apple.com')
  • bad WWDC id and year 2013 give clear 'not found in the bundled WWDC data' errors
  • a nonsense docs-map query says no page matches.

What breaks

  • Setup: package engines require Node ^22.22.2 || ^24.15.0 || >=26. On Node 20.19.2 the server crashes at startup with 'TypeError: Cannot read properties of undefined (reading 'bind')' in undici's zstd decompressor. npm only prints an EBADENGINE warning
  • and the README states the requirement only as a badge. Slow by design: searches took 8-19 s each because of a hard-coded 15 s spacing between searches (constants.js SEARCH_SPACING_MS, 'Apple's search API answers quicker searches with no results'). Doc pages and WWDC/map tools are fast. A nonsense search ('qzxv flurbish wombatkit') returned 'Results found: 20' of unrelated symbols (HIDUsage…vbrx
  • kFWBIBCmc) with no low-confidence signal
  • the tool description warns about this
  • but an agent reading only the result could be misled. list_wwdc_videos silently ignores an unknown 'query' argument and lists all 317 2022 sessions. Observation: the server sends browser-like generated headers (header-generator dependency, 'requests that look like a normal browser's') to Apple. I saw no 429
  • captcha or bot wall in 11 searches and ~10 page fetches. Not tested: Claude Desktop/Code/Cursor hosts, Objective-C language view
  • framework symbol wildcards (source 'index')
  • list_technologies catalogs
  • sample-code pages.

No prior results — this is the first recorded test.

Quality score

4/5 — our subjective hands-on rating on a 1–5 scale.

Quality 4 under the rubric: every tested task passed and edge cases were tried. Answers were checked against developer.apple.com's own JSON and pages: NavigationStack declaration and availability, NavigationView and UIWebView deprecation versions, and the WWDC22 10054 title all matched. Nonsense queries, a nonexistent URL, an off-site URL, a bad WWDC id and a missing year behave sensibly. Not a 5 because it wasn't run in a real MCP host (Claude Desktop/Code need an account), the Node 22.22.2+ requirement is only a README badge and Node 20 crashes with an obscure undici TypeError, nonsense searches return 20 unrelated results with no low-match signal (warned in the tool description), and an unknown argument ('query' on list_wwdc_videos) is silently ignored. Maturity notes, not scored: 25 stars, repo created 2026-10-11, npm 3.0.0 published 2026-10-18.
