How to Set Up and Use Cupertino
Cupertino is an Apple Documentation MCP server and CLI that indexes over 350,000 pages of Apple Developer documentation, 429 Swift Evolution proposals, 619 sample code projects, the Human Interface Guidelines, and Swift.org content into a local SQLite database with BM25F full-text search. It gives AI assistants instant, offline access to the complete Apple developer ecosystem without making live web requests. Developers building iOS, macOS, watchOS, or tvOS applications use it to let Claude look up SwiftUI APIs, UIKit references, Swift language proposals, and sample code with precise, up-to-date answers grounded in official Apple sources.
Prerequisites
- macOS 15 Sequoia or later
- Approximately 4.2 GB of free disk space for the documentation databases
- Swift 6.3+ and Xcode 26+ only if building from source (not required for binary install)
- An MCP client such as Claude Desktop, Claude Code, Cursor, or VS Code Copilot
Install the Cupertino binary
Use the one-command installer which downloads a signed binary to /usr/local/bin. Alternatively, install via Homebrew if you prefer a managed package.
bash <(curl -sSL https://raw.githubusercontent.com/mihaelamj/cupertino/main/install.sh)Alternative: install via Homebrew
If you prefer Homebrew, tap the Cupertino tap and install from there.
brew tap mihaelamj/tap
brew install cupertinoDownload and index the documentation databases
Run the setup command to fetch all Apple documentation corpora. This downloads roughly 4.2 GB and may take several minutes depending on your connection speed.
cupertino setupVerify the databases are healthy
Run the built-in diagnostics command to confirm all databases loaded correctly before configuring your MCP client.
cupertino doctorRegister the MCP server with Claude Code
For Claude Code users, the simplest registration is a single CLI command that adds Cupertino as a user-scoped MCP server.
claude mcp add cupertino --scope user -- $(which cupertino)Or add to Claude Desktop config manually
For Claude Desktop or other clients, add the server configuration to your claude_desktop_config.json. The cupertino binary serves MCP traffic via stdio when invoked without arguments.
{
"mcpServers": {
"cupertino": {
"command": "/usr/local/bin/cupertino"
}
}
}Test a search from the CLI
Before relying on the MCP server, confirm search works from the terminal.

claude_desktop_config.json entry for Cupertino. Replace the binary path with the output of `which cupertino` if it differs.
{
"mcpServers": {
"cupertino": {
"command": "/usr/local/bin/cupertino"
}
}
}Prompts to try
Once connected, ask your AI assistant about Apple APIs, Swift proposals, or sample projects.
- "Look up the SwiftUI NavigationStack API and show me its initializers"
- "Find Apple sample code projects that demonstrate Core Data with CloudKit"
- "What does Swift Evolution proposal SE-0401 change about parameter packs?"
- "Show me the Human Interface Guidelines for iOS tab bars"
- "Search for all SwiftUI view modifiers related to animation"Troubleshooting Cupertino
cupertino setup fails with 'disk space insufficient'
The database download requires at least 4.2 GB free on the volume where Cupertino stores its data (typically ~/.cupertino). Free up space and re-run `cupertino setup`.
MCP server returns no results for a known API
Run `cupertino doctor` to check database integrity. If databases are corrupt or incomplete, re-run `cupertino setup` to re-download them. Also confirm you are on macOS 15+ as earlier versions are not supported.
Claude Desktop does not see the Cupertino tools
Ensure the binary path in claude_desktop_config.json is absolute (use the output of `which cupertino`). Fully quit and reopen Claude Desktop. Check MCP server logs with `cupertino serve 2>/tmp/cupertino-mcp.log`.
