SilbercueSwift — iOS MCP Server
A native Swift MCP server that gives AI agents structured access to iOS development workflows. The real win here is xcresult parsing: instead of dumping 500 lines of xcodebuild stderr and hoping the agent figures it out, you get pass/fail counts, failure messages with file:line coordinates, code coverage breakdowns, and failure screenshots extracted from the same bundles Xcode uses internally. The 55 tools cover build orchestration, UI automation via element queries and coordinate taps, simulator management, and console log filtering. Screenshot latency sits around 316ms in the free tier, dropping to 15ms in Pro. If you're running iOS test loops or debugging UI state with Claude, this is faster and more legible than piping raw xcodebuild output.
