Ask User Question

Use this MCP tool to ask users questions and get their responses. This is the ONLY way to communicate with the user - they cannot see CLI/terminal output.

Critical Rule

The user CANNOT see your text output or CLI prompts!

If you write "Let me ask you..." and then just output text - THE USER WILL NOT SEE IT. You MUST call this tool to display a modal in the UI.

When to Use

• Clarifying questions before starting ambiguous tasks

• Asking user preferences (e.g., "How would you like files organized?")

• Confirming actions before executing (especially destructive/irreversible ones)

• Getting approval for sensitive actions (financial, messaging, deletion, etc.)

• Any situation where you need user input to proceed

Parameters

{ "questions": [{ "question": "Your question to the user", "header": "Short label (max 12 chars)", "options": [ { "label": "Option 1", "description": "What this does" }, { "label": "Option 2", "description": "What this does" } ], "multiSelect": false }] }

• question (required): The question text to display

• header (optional): Short category label, shown as modal title (max 12 chars)

• options (optional): Array of selectable choices (2-4 recommended)

• multiSelect (optional): Allow selecting multiple options (default: false)

Custom text input: To allow users to type their own response, include an option with label "Other" (case-insensitive). When selected, the UI shows a text input field.

{ "label": "Other", "description": "Type your own response" }

Important: When "Other" is selected, the response will be User responded: [their text] instead of User selected: Other . You must wait for and handle this text response - do NOT proceed as if they selected a predefined option.

Examples

Asking about organization preferences

AskUserQuestion({ "questions": [{ "question": "How would you like to organize your Downloads folder?", "header": "Organize", "options": [ { "label": "By file type", "description": "Group into Documents, Images, Videos, etc." }, { "label": "By date", "description": "Group by month/year" }, { "label": "By project", "description": "You'll help me name project folders" } ] }] })

Confirming a destructive action

AskUserQuestion({ "questions": [{ "question": "Delete these 15 duplicate files?", "header": "Confirm", "options": [ { "label": "Delete all", "description": "Remove all 15 duplicates" }, { "label": "Review first", "description": "Show me the list before deleting" }, { "label": "Cancel", "description": "Don't delete anything" } ] }] })

Simple yes/no confirmation

AskUserQuestion({ "questions": [{ "question": "Should I proceed with sending this email?", "header": "Send email", "options": [ { "label": "Send", "description": "Send the email now" }, { "label": "Cancel", "description": "Don't send" } ] }] })

Response Format

The tool returns the user's selection:

• User selected: By file type

• Single selection

• User selected: Option A, Option B

• Multiple selections (if multiSelect: true)

• User responded: [custom text]

• If user typed a custom response

• User declined to answer the question.

• If user dismissed the modal

Wrong vs Correct

WRONG (user won't see this):

I'll help organize your files. How would you like them organized?

• By type
• By date
• By project

CORRECT (user will see a modal):

AskUserQuestion({ "questions": [{ "question": "How would you like your files organized?", "options": [ { "label": "By type" }, { "label": "By date" }, { "label": "By project" } ] }] })
