ui-ticket-mcp

Human-to-AI code review bridge. Review UI prototypes directly in the browser, then let AI agents read your feedback and fix the code automatically.

You click on elements, write review comments like "This button should be blue" or "The spacing is wrong here", and your AI coding agent (Claude Code, Codex, Cursor, etc.) picks them up via MCP and resolves them - with full context about which element you pointed at, its CSS, position, and surrounding DOM.

How it works

journey
    title Using ui-ticket-mcp
    section Review
      Open your app in browser: 5: You
      Click on a broken element: 4: You
      Write what's wrong: 5: You
    section AI resolves
      Agent reads your feedback: 3: AI
      Agent finds the source file: 4: AI
      Agent fixes the code: 5: AI
      Review disappears: 5: You, AI

One Python process handles everything - MCP protocol for the agent (stdio) and REST API for the browser UI (HTTP). Reviews are stored in a SQLite database inside your project.

Quick Start

1. Connect to your AI agent

Add to your project's .mcp.json (Claude Code, Codex, Cursor, etc.):

{
  "mcpServers": {
    "ui-ticket-mcp": {
      "command": "uvx",
      "args": ["ui-ticket-mcp"],
      "env": {
        "PROJECT_ROOT": "/path/to/your/project",
        "REVIEW_PORT": "3200"
      }
    }
  }
}

Restart the agent. uvx downloads and runs the package automatically - no manual install needed.

Alternative: pip install ui-ticket-mcp, then use "command": "ui-ticket-mcp" instead of uvx.

When the MCP server starts, it also launches a REST API on http://localhost:3200 (or your custom REVIEW_PORT) for the browser UI.

Important: The API always runs locally (localhost). The website https://uiticket.0ics.ai/ is the landing page only — it is NOT an API endpoint. Always use http://localhost:{PORT}/api as the api-url.

2. Add the browser UI to your app

npm install ui-ticket-panel

In your app's entry file (e.g. main.ts, index.tsx):

import { defineReviewPanel } from 'ui-ticket-panel';
defineReviewPanel();

Then in your root template:

<review-panel api-url="http://localhost:3200/api"></review-panel>

That's it. Works in any framework - Angular, React, Vue, Svelte, or plain HTML. It's a standard Web Component. For SSR frameworks (Next.js, Nuxt, SvelteKit) see the Framework Examples section — you need a dynamic import on the client side.

No bundler? Use CDN

<script type="module" src="https://unpkg.com/ui-ticket-panel/dist/bundle.js"></script>
<review-panel api-url="http://localhost:3200/api"></review-panel>

The bundle auto-registers the <review-panel> element. No npm install, no build step needed.

3. Start reviewing

Open your app in the browser. You'll see a floating chat button in the bottom-right corner. Click it to open the review panel, or press Alt+A to enter annotation mode and click directly on elements.

Browser UI Features

Review Panel

The floating panel lets you browse, filter, and manage all reviews:

• Filter tabs - Switch between Open, Resolved, and All reviews
• Search - Full-text search across all review comments
• Tag filter - Filter by category: general, bug, suggestion, question
• Per-review actions - Resolve, Reopen, Delete, Reply, Highlight element
• Threaded replies - Reply to reviews for back-and-forth discussion
• Manual review form - Write reviews without annotation (Ctrl+Enter to submit)
• Badge counter - Floating button shows count of open reviews

Annotation System

The annotation system lets you point at specific elements and attach reviews to them:

• Click-to-annotate - Press Alt+A (or the target button), then click any element
• Multi-select drag - Click and drag to select a region of multiple elements
• Hover preview - See element identification in real-time as you move the mouse
• Smart popup - Appears above or below the element depending on available space

When you annotate an element, the system captures rich metadata that helps the AI agent understand exactly what you're pointing at:

Marker Badges

Reviews with annotations show numbered badges on the page next to the annotated element:

• Single review - Circular badge with the review ID, colored red (open) or green (resolved)
• Stacked reviews (3+ on the same element) - Pill badge showing count, with a gradient showing open/resolved ratio
• Click badge - Opens the review in the panel
• Delete badge - Remove via the X button on hover
• Tooltip - Hover to see author, element name, and comment preview

Tags

Every review can be tagged with a category:

MCP Tools

10 tools available to AI agents:

get_review_summary()

Overview of all pages with review counts.

Page         | Open | Resolved | Total
------------ | ---- | -------- | -----
user-profile |    3 |        1 |     4
dashboard    |    0 |        2 |     2

get_reviews(page_id?: str)

List review comments. Optionally filtered by page. Shows status, tag, element context, and reply chains.

[#1] [OPEN] [bug] user-profile - alice: The header spacing is off
  → Element: Heading 2 'User Profile' | Selector: h2.page-title
[#2] [RESOLVED] user-profile - bob: Button color should be blue

get_annotated_reviews(page_id?: str)

Returns only reviews that have element annotation metadata. Includes element name, CSS selector, full DOM path, selected text, accessibility info - everything the agent needs to locate and understand the annotated element.

get_pending_work()

All open reviews grouped by page - the agent's "todo list".

## user-profile (2 open)
  - #1 [bug] (alice): The header spacing is off
  - #3 [suggestion] (alice): Add hover state to buttons

## dashboard (1 open)
  - #4 (bob): Chart labels are truncated

add_review(page_id, author, text, tag?, metadata?, parent_id?)

Create a new review. Supports tags, annotation metadata (JSON), and threading via parent_id.

resolve_review(review_id, resolved_by?)

Mark a review as resolved. Sets resolved_at timestamp and resolved_by (defaults to "agent").

reopen_review(review_id)

Reopen a previously resolved review. Clears resolution info.

batch_resolve(page_id, resolved_by?)

Resolve all open reviews on a page at once. Returns Resolved 3 review(s) on user-profile.

find_source_file_tool(page_id)

Find source files in PROJECT_ROOT matching a page ID. Searches by kebab-case, CamelCase, and glob patterns. Skips node_modules, dist, .git.

Found 3 file(s) for 'user-profile':
  - src/app/user-profile/user-profile.component.ts
  - src/app/user-profile/user-profile.component.html
  - src/app/shared/UserProfile.ts

get_setup_guide()

Returns the full setup guide (MCP config, REST API, browser UI). Useful when the agent needs to help set up the review system in a new project.
