MCP Elicitation allows goose to pause and ask you for specific information when an extension needs it. Instead of guessing or making assumptions, goose presents a form requesting exactly what's needed to continue.

This feature is automatically enabled in goose. When an extension that supports elicitation needs information from you, a form will appear in your session.

<div class="callout callout-note">

[MCP Elicitation](https://modelcontextprotocol.io/specification/draft/client/elicitation) is a feature in the Model Context Protocol. goose supports form mode requests.

## How MCP Elicitation Works

When an extension needs information, goose pauses and presents a form for you to fill out. You can submit your response or cancel the request.

**goose Desktop**

A form appears inline in the chat with:
- Fields for the requested data
- Required fields marked with an asterisk (*)
- Default values you can accept or change
- A **Submit** button to send your response

After submitting, you'll see a confirmation message.

**goose CLI**

A prompt appears in your terminal with:
- A message explaining what information is needed (in cyan)
- Field names (in yellow) with descriptions
- Required fields marked with a red asterisk (*)
- Default values shown in brackets, e.g., `[default]`

Type your response for each field and press Enter. For yes/no questions, you'll see an interactive toggle.

To cancel the request, press `Ctrl+C`.

<div class="callout callout-note">

**Timeout**

Elicitation requests timeout after 5 minutes. If you don't respond in time, the request is cancelled and goose will continue without the information.
