Common questions

Is Uxloom safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 3 months ago, and the latest version (0.14.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

UXLoom

Your generator gave you 6 screens. UXLoom proves you're missing 9 states.

AI generators (v0, Lovable, Figma Make, Claude) produce happy-path screens. UXLoom is the critic layer: it models user journeys as state machines, treats screens as nodes with state contracts, and mechanically proves what's missing before a line of production code exists — unreachable screens, dead ends, missing error/empty/loading states, WCAG contrast failures, undersized touch targets, and labels that will overflow under localization.

Agent-native by design: the interface is an MCP server (works with Claude Code, Codex, and any MCP client), with Agent Skills included.

Deterministic by design: same input, byte-identical report — benchmarked (packages/bench) at 1.000 precision/recall on a seeded defect catalog, SHA-256-stable across processes, 1000 screens in under 5ms. That's what lets design completeness gate CI, where an LLM opinion can't.

uxloomThe MCP server + Agent Skills — the interface agents use

New here? Start with the [Quickstart](QUICKSTART.md) — prerequisites, the Claude Code walkthrough, what to say to your agent, and troubleshooting.

Quick start (agents)

# Claude Code

claude mcp add uxloom -- npx -y uxloom

Codex CLI

codex mcp add uxloom -- npx -y uxloom

The project file (uxloom.project.json) lives in your workspace and belongs in git — the design is data, versioned next to the code it specifies.

Quick start (humans & CI)

npx uxloom init      # one-command setup: MCP config + agent skill + starter file

npx uxloom preview # live mocks (themed, commentable, EDITABLE in the browser) npx uxloom export # shareable HTML — plus --svg (Figma/Penpot import; add

--manifest for the round-trip key) and --png (playwright)

npx uxloom check # design completeness — exit 1 on errors, CI-ready npx uxloom audit # implementation drift — web AND native (Swift/Kotlin/

Dart/Java markers); --live verifies the real DOM;

--design audits a Figma/Penpot export vs the contract

npx uxloom diff # human-readable design diffs for PR review

Evidence-based design: every decision in the contract can carry its rationale — reasoning, rejected alternatives with pros/cons, sources, confidence — enforced by the critics once adopted, iterated through a bounded design_review loop (max 3 rounds), and shown to stakeholders in the preview's evidence panel (ⓘ) and exports. The design doesn't just validate; it argues its case.

Agent-addressable comments: a reviewer drops a pinned comment in the preview and clicks "→ agent". The comment becomes a work item any Gen-AI model can read with full context — comment_context returns the pinned layout block, the screen contract, the journey references, and the current findings for that screen — act on, and resolve back into the preview with a note. One click from feedback to addressed.

CI-native: check and audit take --json, --sarif (GitHub code scanning), and --github (inline PR annotations). Brownfield-ready: --update-baseline freezes existing findings so only *new* drift blocks; uxloom.config.json tunes thresholds to your accessibility bar. Full documentation: uxloom.dev/docs.html.

Add it to CI and a happy-path-only design can never merge:

- run: npx uxloom check design/uxloom.project.json

Workflow (also shipped as a skill in packages/mcp-server/skills/): project_init → brief_start/brief_answer → journey_define → screen_register → project_validate → fix → repeat until zero errors → coverage_report.

Does it actually catch things?

tools/dogfood.mjs drives the real MCP server through three products, twice each: screens as a happy-path generator hands them over, then repaired using the validation report. Artifacts in examples/.

ProductGenerated (happy-path)Repaired
shopmweb — e-commerce checkout (mWeb + Android)9 errors, 6 warnings0 / 0
taskflow — SaaS signup/onboarding (web)1 error, 6 warnings0 / 0
ridenow — ride booking (iOS + Android, offline-heavy)3 errors, 7 warnings0 / 0

Caught: an unreachable promo screen, dead-end verification states, five undesigned payment/error states, a 2.4:1 contrast button, a 40px touch target on Android, a checkout label that breaks in German, and three products' worth of missing offline states. Zero errors *and zero warnings* is reachable honestly — screens declare documented exemptions where a baseline state genuinely cannot apply, and contradictory exemptions are flagged.

Development

npm install

npm run typecheck npm test

Status

Released and maintained: on npm and the official MCP registry, with the benchmark scorecard published in every GitHub release. The JourneyGraph format (formatVersion: "0.1") may evolve until 1.0; releases follow RELEASING.md — every surface is drift-checked in CI.
