🎯 Core Concept

This is an MCP server 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 | Cline | Windsurf | Augment | Trae

🔄 Workflow

1. AI Call → mcp-feedback-enhanced-gw 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:

{
  "mcpServers": {
    "mcp-feedback-enhanced-gw": {
      "command": "uvx",
      "args": ["mcp-feedback-enhanced-gw@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

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:

{
  "mcpServers": {
    "mcp-feedback-enhanced-gw": {
      "command": "uvx",
      "args": ["mcp-feedback-enhanced-gw@latest"],
      "timeout": 600,
      "env": {
        "MCP_DESKTOP_MODE": "true",
        "MCP_WEB_PORT": "8765"
      },
      "autoApprove": ["interactive_feedback"]
    }
  }
}

Configuration File Example: 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-enhanced-gw@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-enhanced-gw@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:

# 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

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
