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

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

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

Save and refresh
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>

user-prompt-mcp --timeout 600  # Set timeout to 10 minutes

Environment variable: USER_PROMPT_TIMEOUT=<seconds>

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.
