Pepper vs chiasmus

Pepper: Pepper is an MCP server that injects a dylib into iOS Simulator apps via DYLD_INSERT_LIBRARIES, starting a WebSocket server inside the app process to expose over 50 tools for view hierarchy, touch input, network interception, heap inspection, and more. It simplifies giving AI agents full runtime access to iOS apps for testing and automation.; chiasmus: Chiasmus is an MCP server that integrates formal verification (Z3, Prolog) and code analysis (tree-sitter) to solve complex logical and structural problems. It translates natural language into formal logic using templates and provides verified results. It also analyzes source code call graphs for dead code, impact, and reachability.
