AI code review for the CLI, CI, and MCP hosts. Review staged changes locally, gate PRs in CI, or drive the engine from any MCP-capable agent (Claude Code, Codex, and others). Deterministic engine + LLM, stable JSON envelope on stdout.

Full guide: Getting started

• Local review — staged changes, commit range, or a single commit
• GitHub PR review — inline comments, one upserted summary, head-SHA anchoring, fork-safe
• CI / GitHub Action — drop-in reusable action; see examples/workflows/
• Project rules — .miu/cr/rules/*.md glob-scoped context injected per file
• Evaluation — miucr eval compares reviewer commands against expected findings
• MCP server — miucr mcp exposes review_run / review_get over stdio

go test ./...          # table tests + fakes, no live network or LLM
