User Prompt MCP

A Model Context Protocol (MCP) server for Cursor that enables requesting user input during generation. This is mostly AI-generated code.

Overview

This project implements an MCP server that allows Cursor (or any MCP-compatible client) to request additional input from users during model generation without ending the generation process. It serves as a bridge between the AI model and the user, creating a more interactive experience.

Features

• User Input Prompting: Allows the AI to ask for more information during generation
• Simple GUI: Presents input prompts in a dialog box with text wrapping
• Cross-Platform: Should work on both Linux (tested) and macOS
• Stdio Transport: Integration with Cursor via stdio

Installation

Prerequisites

• For GUI functionality:
• Linux: zenity
• macOS: osascript (built-in)

Quick Install (Recommended)

The easiest way to install user-prompt-mcp is using our installation script, which automatically downloads the appropriate binary for your system:

# Install the latest version
curl -sSL https://raw.githubusercontent.com/nazar256/user-prompt-mcp/main/install.sh | bash

# Or install a specific version
curl -sSL https://raw.githubusercontent.com/nazar256/user-prompt-mcp/main/install.sh | bash -s -- -v v1.0.0

The installation script will: - Detect your OS and architecture (Linux or macOS, amd64 or arm64) - Download the appropriate pre-compiled binary - Install it to a suitable directory in your PATH - Make it executable

Install from source

If you prefer to build from source (requires Go 1.18+):

go install github.com/nazar256/user-prompt-mcp/cmd/user-prompt-mcp@latest

Manual Installation

You can also download pre-compiled binaries directly from the Releases page.

Usage with Cursor

1. Open Cursor and go to Settings
2. Navigate to the MCP Servers section and add a new server by editing JSON:

{
  "mcpServers": {
    "prompt": {
      "command": "user-prompt-mcp"
    }
  }
}

1. Save and refresh

2. Add to global rules something like: "Important - do not finish responding until explicitly told to do so, instead always use MCP input_user_prompt and wait for response in all cases, either you feel stuck, you have question or you finished work on a prompt - always communicate with the user using this MCP."

Configuration

The server can be configured using command-line flags or environment variables:

Timeout Configuration

By default, the server will wait 20 minutes for user input before timing out. You can customize this timeout using:

• Command line flag: --timeout <seconds> bash user-prompt-mcp --timeout 600 # Set timeout to 10 minutes
• Environment variable: USER_PROMPT_TIMEOUT=<seconds> bash export USER_PROMPT_TIMEOUT=1800 # Set timeout to 30 minutes user-prompt-mcp

Now when using Cursor, the AI can request additional input from you without ending its generation.
