onetool-mcp vs Pepper
onetool-mcp: OneTool MCP is a single MCP server that bundles 100+ tools — Brave search, Google, Context7, AWS, Playwright, Chrome DevTools, Excel, database operations, and more. Instead of registering each tool individually and burning context on their definitions, agents write short Python code to call any tool on demand. Anthropic engineering research backs this approach: code execution reduces token usage by over 98%, cutting costs dramatically when agents need many external tools.; 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.
