apple-docs

All of Apple's developer documentation, on your machine. Search it from the terminal, browse it in your browser, and plug it into Claude, Codex, Cursor, or any other MCP client — fully offline once installed.

One indexed corpus (~353,000 documents), three ways in:

• CLI — apple-docs search "NavigationStack" answers in milliseconds.
• MCP server — your AI assistant cites real Apple docs instead of guessing.
• Local website — browse and full-text search in the browser, or publish it as a static site.

It covers Apple's API reference (DocC), Human Interface Guidelines, App Store Review Guidelines, Swift Evolution, the Swift book, Swift.org, WWDC sessions (1997–2026, transcripts included), Apple sample code, archived documentation, a Swift package catalog, every SF Symbol, and Apple's fonts.

Quick start

You need Bun 1.1+.

git clone https://github.com/g-cqd/apple-docs.git
cd apple-docs
bun run dev:setup    # install dependencies + link the CLI
apple-docs setup     # download + install the latest snapshot

setup downloads one verified archive (1.89 GB) and installs it in a few minutes. After that, everything works offline:

apple-docs search "NavigationStack"
apple-docs search "how do I record audio in the background"
apple-docs read swiftui/view

Search takes both forms: exact symbol names and plain-English questions (a local semantic index is built during setup — no cloud, no API key).

Pick a disk/speed tradeoff (optional)

setup asks which storage profile you want; flags skip the prompt:

	Command	Disk	Best for
Smallest	apple-docs setup --compact	~4.6 GB	laptops, CI
Default	apple-docs setup	~7.1 GB	most setups
Fastest reads	apple-docs setup --prebuilt	~10.5 GB	serving the website

All three contain the full corpus and search identically — they only trade disk for read speed. Details and how to switch later: docs/configuration.md.

Prefer a standalone binary or a production self-host? See docs/installing.md.

Everyday commands

# Search — filters beat clever queries
apple-docs search "Swift Testing" --source wwdc --year 2024
apple-docs search "privacy" --framework app-store-review
apple-docs search "scroll" --kind article --platform visionos

# Read a page (or just one section of it)
apple-docs read swiftui/view
apple-docs read View --framework swiftui
apple-docs read swiftui/view --section Overview

# Explore
apple-docs frameworks                  # every documentation root
apple-docs browse swiftui              # a framework's pages
apple-docs browse wwdc                 # WWDC years with session counts
apple-docs browse wwdc --year 2025     # one year's sessions
apple-docs status                      # corpus freshness + counts

apple-docs --help and apple-docs <command> --help are the exhaustive reference.

Use it from your AI tools (MCP)

apple-docs mcp install            # prints ready-to-paste client config
apple-docs mcp start              # stdio server
apple-docs mcp serve --port 3031  # Streamable HTTP server

Nine read-only tools: search_docs, read_doc, list_frameworks, browse, list_taxonomy, search_sf_symbols, list_apple_fonts, render_sf_symbol, render_font_text — plus resources for docs, frameworks, SF Symbol renders, and font files.

The tool surface is deliberately context-cheap: definitions cost ~2.2k tokens total (about a quarter of a typical multi-tool MCP server), responses are compact JSON with pagination built in, and a CI budget test keeps it that way. Your context window stays available for actual work.

HTTP mode has no built-in auth — keep it on loopback unless a reverse proxy or tunnel handles access control.

Public instance

A best-effort public deployment (no uptime SLA; self-host for production):

claude mcp add -s user --transport http apple-docs https://apple-docs-mcp.everest.mt/mcp
codex mcp add apple-docs -- bunx mcp-remote https://apple-docs-mcp.everest.mt/mcp

Local website

apple-docs web serve                  # http://127.0.0.1:3000
apple-docs web build --out dist/web   # static site

The server is agent-friendly out of the box: append .md to any doc URL for Markdown (/docs/swiftui/view.md), and discovery endpoints are served at /robots.txt, /.well-known/api-catalog (RFC 9727), and /.well-known/mcp/server-card.json. Deployment recipes: apple-docs web deploy <github-pages|cloudflare|vercel|netlify> and docs/self-hosting.md.

Keeping it fresh

Snapshots are rebuilt weekly by CI. To update, re-run:

apple-docs setup --force

Running a newer macOS than CI? apple-docs setup --beta --force opts into prerelease snapshots built on developer machines, which carry SF Symbols the stable CI builds can't produce yet (details).

Or skip snapshots entirely and crawl Apple's docs yourself:

apple-docs sync          # resumable, idempotent refresh
apple-docs sync --full   # clean rebuild

sync also merges Xcode's offline documentation asset when one is available locally (USRs and a few thousand pages the public crawl can't see) — CI does this for every published snapshot, so installed snapshots already include it.

Build your own portable snapshot with apple-docs snapshot build --out dist, install it with apple-docs setup --archive <path>.

Scoping the corpus (optional)

The full corpus is ~4.6–10.5 GB on disk depending on the storage profile. If you only need a slice of it, drop a scope.json into your data directory (default ~/.apple-docs) saying what to keep:

{
  "version": 1,
  "sources": ["apple-docc", "hig", "swift-book"],
  "appleDoccFrameworks": ["swiftui", "combine"],
  "keepFonts": true,
  "keepSymbols": false
}

Every field is optional except version — omit sources to keep all sources, omit appleDoccFrameworks to keep every framework. Then:

apple-docs prune --dry-run   # preview what would be removed
apple-docs prune             # trim the existing corpus, reclaim disk

prune deletes the out-of-scope pages (search indexes, semantic vectors, and on-disk files included) without re-crawling anything, and future apple-docs sync runs read the same file so the corpus stays scoped. Delete scope.json and sync to grow back to full coverage. No scope.json means nothing changes — full coverage is the default.
