Solo dev builds MCP-read analytics entirely with Claude Code, 180 commits

A Redditor shipped a cookieless website analytics product with an MCP server — all 180 commits since Oct 2 made in Claude Code sessions, mostly Opus — so Claude can answer 'why did traffic spike?' from live data. Key lessons: the spike detector compares each hour to same-hour medians and ranks sources/pages/events; the original curl install was blocked by Claude Code's auto mode as a risky download, so they rebuilt it as an OAuth MCP connection (claude mcp add + browser sign-in, no API key); they wrote an eval asking Claude Code and Codex to 'add analytics' vendor-agnostically — baseline recommends Plausible/PostHog, theirs 0/36. 30-day free trial plus install guide available.
