Pepper vs gram

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.; gram: Gram is a cloud platform for creating, curating, and hosting MCP servers with ease. It supports OpenAPI documents and custom TypeScript functions to define tools, and provides a hosted and secure MCP server for every toolset. Gram empowers LLMs and agents to access the right data at the right time.
