**UI Design Reference:** [sanshao85/mcp-feedback-collector](https://github.com/sanshao85/mcp-feedback-collector)

## 🎯 Core Concept

This is an [MCP server](https://modelcontextprotocol.io/) that establishes **feedback-oriented development workflows**, providing **Web UI and Desktop Application** dual interface options, perfectly adapting to local, **SSH Remote environments**, and **WSL (Windows Subsystem for Linux) environments**. By guiding AI to confirm with users rather than making speculative operations, it can consolidate multiple tool calls into a single feedback-oriented request, dramatically reducing platform costs and improving development efficiency.

**🌐 Dual Interface Architecture Advantages:**
- 🖥️ **Desktop Application**: Native cross-platform desktop experience, supporting Windows, macOS, Linux
- 🌐 **Web UI**: No GUI dependencies required, suitable for remote and WSL environments
- 🔧 **Flexible Deployment**: Choose the most suitable interface mode based on environment requirements
- 📦 **Unified Functionality**: Both interfaces provide exactly the same functional experience

**🖥️ Desktop Application:** v2.5.0 introduces cross-platform desktop application support based on Tauri framework, supporting Windows, macOS, and Linux platforms with native desktop experience.

**Supported Platforms:** [Cursor](https://www.cursor.com) | [Cline](https://cline.bot) | [Windsurf](https://windsurf.com) | [Augment](https://www.augmentcode.com) | [Trae](https://www.trae.ai)

### 🔄 Workflow
1. **AI Call** → `mcp-feedback-hall` tool
2. **Interface Launch** → Auto-open desktop application or browser interface (based on configuration)
3. **Smart Interaction** → Prompt selection, text input, image upload, auto-submit
4. **Real-time Feedback** → WebSocket connection delivers information to AI instantly
5. **Session Tracking** → Auto-record session history and statistics
6. **Process Continuation** → AI adjusts behavior or ends task based on feedback

## 🐛 Common Issues

### 🌐 SSH Remote Environment Issues
**Q: Browser cannot launch or access in SSH Remote environment**
A: Two solutions available:

**Solution 1: Environment Variable Setting (v2.5.5 Recommended)**
Set `"MCP_WEB_HOST": "0.0.0.0"` in MCP configuration to allow remote access:
```json
{
  "mcpServers": {
    "mcp-feedback-hall": {
      "command": "uvx",
      "args": ["mcp-feedback-hall@latest"],
      "timeout": 600,
      "env": {
        "MCP_WEB_HOST": "0.0.0.0",
        "MCP_WEB_PORT": "8765"
      },
      "autoApprove": ["interactive_feedback"]
    }
  }
}
```
Then open in local browser: `http://[remote-host-IP]:8765`

**Solution 2: SSH Port Forwarding (Traditional Method)**
1. Use default configuration (`MCP_WEB_HOST`: `127.0.0.1`)
2. Set up SSH port forwarding:
   - **VS Code Remote SSH**: Press `Ctrl+Shift+P` → "Forward a Port" → Enter `8765`
   - **Cursor SSH Remote**: Manually add port forwarding rule (port 8765)
3. Open in local browser: `http://localhost:8765`

For detailed solutions, refer to: [SSH Remote Environment Usage Guide](docs/en/ssh-remote/browser-launch-issues.md)

**Q: Why am I not receiving new MCP feedback?**
A: Likely a WebSocket connection issue. **Solution**: Directly refresh the browser page.

**Q: Why isn't MCP being called?**
A: Please confirm MCP tool status shows green light. **Solution**: Repeatedly toggle MCP tool on/off, wait a few seconds for system reconnection.

**Q: Augment cannot start MCP**
A: **Solution**: Completely close and restart VS Code or Cursor, reopen the project.

### 🔧 General Issues
**Q: How to use desktop application?**
A: v2.5.0 introduces cross-platform desktop application support. Set `"MCP_DESKTOP_MODE": "true"` in MCP configuration to enable:
```json
{
  "mcpServers": {
    "mcp-feedback-hall": {
      "command": "uvx",
      "args": ["mcp-feedback-hall@latest"],
      "timeout": 600,
      "env": {
        "MCP_DESKTOP_MODE": "true",
        "MCP_WEB_PORT": "8765"
      },
      "autoApprove": ["interactive_feedback"]
    }
  }
}
```
**Configuration File Example**: [examples/mcp-config-desktop.json](examples/mcp-config-desktop.json)

**Q: How to use legacy PyQt6 GUI interface?**
A: v2.4.0 completely removed PyQt6 GUI dependencies. To use legacy GUI, specify v2.3.0 or earlier: `uvx mcp-feedback-hall@2.3.0`
**Note**: Legacy versions don't include new features (prompt management, auto-submit, session management, desktop application, etc.).

**Q: "Unexpected token 'D'" error appears**
A: Debug output interference. Set `MCP_DEBUG=false` or remove the environment variable.

**Q: Chinese character garbled text**
A: Fixed in v2.0.3. Update to latest version: `uvx mcp-feedback-hall@latest`

**Q: Window disappears or positioning errors in multi-screen environment**
A: Fixed in v2.1.1. Go to "⚙️ Settings" tab, check "Always show window at primary screen center" to resolve. Especially suitable for T-shaped screen arrangements and other complex multi-screen configurations.

**Q: Image upload failure**
A: Check file format (PNG/JPG/JPEG/GIF/BMP/WebP). System supports any size image files.

**Q: Web UI cannot start**
A: Check firewall settings or try using different ports.

**Q: UV Cache occupies too much disk space**
A: Due to frequent use of `uvx` commands, cache may accumulate to tens of GB. Regular cleanup recommended:
```bash
# View cache size and detailed information
python scripts/cleanup_cache.py --size

# Preview cleanup content (no actual cleanup)
python scripts/cleanup_cache.py --dry-run

# Execute standard cleanup
python scripts/cleanup_cache.py --clean

# Force cleanup (attempts to close related programs, solving Windows file occupation issues)
python scripts/cleanup_cache.py --force

# Or directly use uv command
uv cache clean
```
For detailed instructions, refer to: [Cache Management Guide](docs/en/cache-management.md)

**Q: AI models cannot parse images**
A: Various AI models (including Gemini Pro 2.5, Claude, etc.) may have instability in image parsing, sometimes correctly recognizing and sometimes unable to parse uploaded image content. This is a known limitation of AI visual understanding technology. Recommendations:
1. Ensure good image quality (high contrast, clear text)
2. Try uploading multiple times, retries usually succeed
3. If parsing continues to fail, try adjusting image size or format
