How to Set Up and Use AskUserQuestion Plus
AskUserQuestion Plus is a Streamable HTTP MCP server that lets AI coding assistants like Claude Code, Codex, and Gemini CLI pause execution and ask the user structured questions through a web interface. When triggered, it automatically opens a browser tab with a polished questionnaire supporting single-choice, multiple-choice, and custom text input, then returns the answers to the AI model to continue the task. It is inspired by Claude Code's native AskUserQuestion tool but works across multiple AI clients.
Prerequisites
- Node.js 18 or higher with npm available
- Claude Code, OpenAI Codex, or Gemini CLI as your AI client
- A web browser for viewing the question interface
- Port 3456 available on localhost (configurable)
Start the AskUserQuestion Plus server
Run the server using npx, which downloads and starts it without a global installation. The server listens on port 3456 by default and opens a browser tab when questions are requested.
npx ask-user-question-plusOptionally customize port and timeout
Pass custom port and timeout values if the defaults conflict with other services. Timeout is in milliseconds; the default 600000ms is 10 minutes.
npx ask-user-question-plus -- --port=3456 --timeout=600000Run the server persistently with pm2
For long-running sessions, use pm2 to keep the server running in the background even after your terminal closes.
npm install -g pm2
pm2 start "npx ask-user-question-plus" --name ask-user-question-plus-serviceConfigure Claude Code to connect to the server
Register the server with Claude Code using the mcp add command with the HTTP transport type pointing to the local endpoint.
claude mcp add -s user -t http AskUserQuestionPlus http://localhost:3456/mcpAsk your AI to use the tool
In your Claude Code, Codex, or Gemini CLI session, instruct the AI to use the ask_user_question_plus tool to gather structured input before proceeding with a task.

}Prompts to try
Example prompts that instruct the AI to use ask_user_question_plus to gather user preferences before executing tasks.
- "Before creating the component, use ask_user_question_plus to ask me which framework I prefer: React, Vue, or Svelte"
- "Use ask_user_question_plus to ask me 3 questions about my API design preferences before writing the code"
- "Ask me whether I want dark or light theme, TypeScript or JavaScript, and which CSS framework to use"
- "Use the question tool to confirm my deployment target before running the deploy script"Troubleshooting AskUserQuestion Plus
Browser tab does not open automatically when questions are requested
The server attempts to open the default browser automatically. If this fails, open http://localhost:3456 manually in your browser after the AI triggers the tool. Check if a firewall or browser policy is blocking localhost navigation.
Claude Code shows connection refused when adding the MCP server
Make sure the ask-user-question-plus server is running before registering it with Claude Code. Run npx ask-user-question-plus first, confirm it shows a listening message, then run the claude mcp add command.
Session timeout before the user submits answers
Increase the timeout with the --timeout flag (value in milliseconds). For complex questionnaires, set --timeout=1800000 for a 30-minute window. The session expires if the user does not submit within the configured duration.
