askq

Native GUI for AskUserQuestion-style multiple-choice prompts, for AI coding agents. A blocking CLI: feed it the questions JSON, the user answers in a real window, it prints the answers JSON to stdout and exits. Also runs as an MCP server.

npm install -g askq-cli

This installs the askq command. (The package is askq-cli because the bare name askq is blocked by npm's similarity filter; the CLI itself is askq.) The right prebuilt binary for your platform is pulled in automatically as an optional dependency (askq-darwin-arm64, askq-linux-x64, askq-linux-arm64).

Use

# CLI: pipe questions in, read answers out
echo '{"questions":[{"question":"Pick one","header":"Demo","multiSelect":false,
  "options":[{"label":"A","description":"first"},{"label":"B"}]}]}' | askq
# => {"questions":[...],"answers":{"Pick one":"A"}}

askq --help        # full input/output schema
askq mcp           # run as an MCP server (stdio) exposing ask_user_question

MCP

Register it with any MCP client (Claude Code .mcp.json, Cursor .cursor/mcp.json, …):

{ "mcpServers": { "askq": { "command": "askq", "args": ["mcp"] } } }
