Periphery Code Audit

zyntx-lab/periphery-mcp-server

Wraps the Periphery CLI to surface Swift code analysis through MCP, giving you seven tools for detecting unused code in iOS and macOS projects. You can run basic scans with scan_project, check for redundant public declarations, analyze unused imports, or use scan_with_config for YAML-based workflows. Output comes back as structured JSON that Claude can parse and reason about. Most useful when you're auditing a codebase and want AI assistance identifying dead code, over-scoped declarations, or import bloat without manually running command line scans. Requires Periphery already installed via Homebrew and works with both Xcode projects and Swift Packages.
