Switch QCut's center Preview Panel between normal video preview and MCP app mode, validate iframe rendering, and debug MCP HTML delivery through IPC and HTTP endpoints. Use when asked to test, demo, or troubleshoot MCP app preview behavior, the "MCP Media App" toggle, `mcp:app-html` events, `/api/claude/mcp/app`, or to craft prompts for Claude that modify the MCP media app UI safely.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# QCut MCP Preview Test
## Architecture
QCut's preview panel supports two rendering modes: **Video Preview** (default) and **MCP App** (interactive iframe). The MCP system has two independent input paths:
```
┌─────────────────────────────────────────────────┐
│ Preview Panel (preview-panel.tsx) │
│ │
│ Mode 1: Video Preview (default) │
│ → Canvas-based video playback │
│ │
│ Mode 2: MCP App (iframe srcDoc) │
│ ├─ Local: built-in PersonaPlex template │
│ │ toggled by "MCP Media App" button │
│ │ state: localMcpActive = true │
│ │ │
│ └─ External: HTML from Claude MCP tools │
│ received via IPC mcp:app-html event │
│ state: activeHtml + toolName set │
└─────────────────────────────────────────────────┘
Data Flow (External MCP):
Claude Code → HTTP POST /api/claude/mcp/app
→ claude-http-shared-routes.ts forwards via IPC
→ preview-panel.tsx receives via onAppHtml()

How to install
mdr add quriosity-agent/qcut/qcut-mcp-preview-test@sha256:a1ca548f1812cb12The line at the top of this page pins the label git:20260525.2b74e19, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
