Not Just Another Docs Tool

What Not Just Another Docs Tool does

Not Just Another Docs Tool provides MCP access to a collected Apple developer knowledge base. The indexed material includes official documentation, Apple Developer video transcripts, WWDC26 sessions, and references covering iOS 27, iPadOS 27, macOS 27, watchOS 27, tvOS 27, and visionOS 27. It also includes material related to Xcode 27 beta releases.

The service is designed to return concise source excerpts during search rather than placing an entire document in the agent's context. When an excerpt is insufficient, the agent can use the source URL with fetch to retrieve the complete processed page or video content.

How it works

search uses two retrieval methods: keyword matching for exact technical terms such as API names, and semantic retrieval for questions expressed in broader language. The candidates from both methods are merged and ranked for relevance by Jev, which considers the query's API, platform, and version requirements. A backup reranker is available when the Jev API cannot be reached.

fetch retrieves full cleaned content from Apple's knowledge base for a specific documentation or video URL. Both tools are available through the same MCP connection and share the service's usage limits.

The hosted service handles collection, cleaning, indexing, index updates, database backups, embedding calls, reranking, and MCP protocol compatibility. The source is also public for developers who want to inspect or operate their own instance.

Setup and configuration

The hosted endpoint uses Streamable HTTP:

{
  "mcpServers": {
    "apple-rag-mcp": {
      "type": "http",
      "url": "https://mcp.apple-rag.com"
    }
  }
}

A dashboard can generate an install prompt and provide client-specific configuration examples. Cursor also has a one-click installation option. The connection accepts the MCP protocol version 2026-07-28 and retains compatibility with legacy initialization versions 2025-11-25, 2025-06-18, and 2025-03-26.

No token is needed to begin querying the hosted service. An MCP Token obtained from apple-rag.com can be added for a higher quota. Self-hosting requires operating a database, creating and refreshing the documentation corpus, and managing model API credentials.

Tools and capabilities

• search: Finds Apple documentation and WWDC video transcript excerpts using combined keyword and semantic retrieval, followed by Jev relevance ranking.
• fetch: Returns complete cleaned content for a specified Apple documentation or video URL.
• Retrieves code examples and references relevant to Swift, Objective-C, and SwiftUI material.
• Covers Apple platform documentation and Apple Developer video transcripts through one MCP connection.
• Supports stateless Streamable HTTP with legacy protocol compatibility.

Limitations and notes

The hosted service applies shared rate and usage limits to search and fetch. Anonymous usage is limited to 30 tool calls per week and 3 calls per minute. Registered usage provides 50 calls per week and 5 per minute, while the Pro plan lists 50,000 calls per week and 50 per minute.

Saving an MCP configuration does not itself verify connectivity. After adding the endpoint, the client should establish a connection and verify that the tools are available. Running a private instance shifts corpus maintenance, indexing, storage, backups, and model credential management to the operator.
