fastmcp.apps.choice

Choice — a Provider that lets the user pick from a set of options.

The LLM presents options, the user clicks one, and the selection flows back into the conversation as a message.

Requires fastmcp[apps] (prefab-ui).

Usage::

from fastmcp import FastMCP
from fastmcp.apps.choice import Choice

mcp = FastMCP("My Server")
mcp.add_provider(Choice())

A Provider that lets the user choose from a set of options.

The LLM calls choose with a prompt and a list of options. The user sees a card with one button per option. Clicking a button sends the selection back into the conversation via SendMessage, triggering the LLM's next turn.

Example::

from fastmcp import FastMCP
from fastmcp.apps.choice import Choice

mcp = FastMCP("My Server")
mcp.add_provider(Choice())
