# MCP: Voice capture and confirmation on Ask steps

When authoring Playbook `ask` steps with [`propose_change`](/mcp/tools/propose-change#playbooks), you can now set how each variable is captured and confirmed on Voice.

**Capture method** (`capture_modes`) — how the caller provides the value: speech, phone keypad, SMS, or combinations, depending on the input type.

**Confirmation style** (`confirmation_style`) — how the AI Agent reads a captured value back before continuing: `none`, `implicit`, `echo`, or `spell`. Text and number inputs support all four; boolean supports `none`, `implicit`, and `echo`. Defaults to `implicit`.

The [`get_improvement_guide`](/mcp/tools/get-improvement-guide) now includes guidance on choosing sensible capture and confirmation settings for each kind of value, so your MCP-connected assistant can suggest the right setup when it builds an Ask step.
