MCP Feedback Enhanced Server

Version: 0.1.66

MCP Server component that connects to the VSCode Extension's WebSocket server to collect user feedback.

How It Works

1. Extension starts → Creates WebSocket server → Writes ~/.config/mcp-feedback-enhanced/servers/<pid>.json
2. MCP Server starts → Waits for interactive_feedback call
3. AI calls tool → MCP Server reads server files → Finds matching Extension by workspace path → Connects
4. User submits → Feedback flows back to AI

Server Discovery

MCP Server finds the correct Extension using priority-based matching:

| Priority | Strategy | Description | |----------|----------|-------------| | 1 | CURSOR_TRACE_ID | Same Cursor window (environment variable) | | 2 | Exact workspace | project_directory in server's workspaces array | | 3 | Prefix match | Project is inside a workspace directory | | 4 | parentPid | Same parent process (backward compatibility) | | 5 | Single server | Only one server running | | 6 | Most recent | Last registered server by timestamp |

Tools

interactive_feedback

Collect feedback from user through the VSCode sidebar panel.

{
  project_directory: string;  // Project path for context & server matching
  summary: string;            // AI summary for user review
  timeout?: number;           // Timeout in seconds (default: 600)
}

get_system_info

Returns system environment information.

Configuration

Add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "mcp-feedback-enhanced": {
      "command": "node",
      "args": ["/path/to/mcp-server/dist/index.js"],
      "env": {
        "MCP_FEEDBACK_DEBUG": "true"
      },
      "timeout": 89400,
      "autoApprove": ["interactive_feedback"]
    }
  }
}

Environment Variables

| Variable | Default | Description | |----------|---------|-------------| | MCP_FEEDBACK_DEBUG | false | Enable debug logging to stderr |

Debug Mode

Set MCP_FEEDBACK_DEBUG=true to see:

• Server discovery process
• WebSocket connection status
• Message flow between components

Troubleshooting

"No MCP Feedback Extension found for project"

1. Ensure VSCode extension is installed and activated
2. Open the MCP Feedback panel (click sidebar icon)
3. Check ~/.config/mcp-feedback-enhanced/servers/ for server files
4. Verify your project path is in the workspaces array

Connection timeout

1. Check if Extension's WebSocket server is running (port in server file)
2. Verify no firewall blocking localhost connections
3. Try reloading the Cursor window
