Side-by-side comparison of two Model Context Protocol servers — install paths, tools, quality signals, and directory engagement so you can pick the right one for Claude, Cursor, and other MCP clients.
MCP server for Perfetto trace analysis. Runs PerfettoSQL queries on .perfetto-trace / .pftrace files via auto-downloaded traceprocessorshell, with dedicated Chrome tools for page loads, scroll jank, main-thread hotspots, and stdlib module discovery. Cross-client tested on Claude Code and Codex. Available via cargo install, Homebrew tap, and curl install script.
