Apple Developer Documentation

Provide authoritative guidance from Apple's official developer documentation and WWDC sessions using the apple-rag-mcp MCP server. Prioritize MCP tools over web search for Apple development questions.

Quick start

• Use search to find relevant documentation and WWDC content.
• Use fetch to retrieve the complete, cleaned content of a specific page by URL.
• Always prefer MCP tools over web search for Apple-related questions.

Tool reference

search

search(query: string, result_count?: number)

• query — Must be in English. Focus on technical concepts, API names, framework names, and version numbers. Avoid dates and temporal language.
• result_count — Number of results (1–10, default 4). Use higher values for broad topics, lower for specific APIs.

fetch

fetch(url: string)

Retrieve the full cleaned content of an Apple developer documentation page or WWDC video transcript by its URL.

Workflow

1. Identify scope: Determine which Apple framework, API, or platform the question targets.
2. Search: Run search with a precise English query using framework and API names.
3. Evaluate results: Check each result's completeness indicator:
   • ✅ Complete Document — Full content, use directly.
   • 📄 Part X of Y — Partial content. Run fetch(url) to get the complete document.
   • 📄 Parts merged — Multiple sections merged. Run fetch(url) if you need the full document.
4. Fetch when needed: Use fetch for any result that is partial, or when Additional Related Documentation URLs look relevant.
5. Answer with citations: Reference the source URL so the user can verify.

Query best practices

Good queries — focus on technical terms and API names:

• Core Data CloudKit sync NSPersistentCloudKitContainer
• visionOS RealityKit entity component system
• StoreKit 2 Transaction.currentEntitlements
