v3.2.0: Show Don't Tool

FastMCP 3.2 is the Apps release. The 3.0 architecture gave you providers and transforms; 3.1 shipped Code Mode for tool discovery. 3.2 puts a face on it: your tools can now return interactive UIs — charts, dashboards, forms, maps — rendered right inside the conversation.

FastMCPApp

FastMCPApp is a new provider class for building interactive applications inside MCP. It separates the tools the LLM sees (@app.ui()) from the backend tools the UI calls (@app.tool()), manages visibility automatically, and gives tool references stable identifiers that survive namespace transforms and server composition — without requiring host cooperation.

from fastmcp import FastMCP, FastMCPApp
from prefab_ui.actions.mcp import CallTool
from prefab_ui.components import Column, Form, Input, Button, ForEach, Text
app = FastMCPApp("Contacts")
@​app.tool()
def save_contact(name: str, email: str) -> list[dict]:
db.append({"name": name, "email": email})
return list(db)
@​app.ui()
def contact_manager() -> PrefabApp:
with PrefabApp(state={"contacts": list(db)}) as view:
with Column(gap=4):
ForEach("contacts", lambda c: Text(c.name))
with Form(on_submit=CallTool("save_contact")):
Input(name="name", required=True)
Input(name="email", required=True)
Button("Save")
return view
mcp = FastMCP("Server", providers=[app])

The UI is built with Prefab, a Python component library that compiles to interactive UIs. You write Python; the user sees charts, tables, forms, and dashboards. FastMCP handles the MCP Apps protocol machinery — renderer resources, CSP configuration, structured content serialization — so you don't have to.

For simpler cases where you just want to visualize data without server interaction, set app=True on any tool and return Prefab components directly:

@mcp.tool(app=True)
def revenue_chart(year: int) -> PrefabApp:
    with PrefabApp() as app:
        BarChart(data=revenue_data, series=[ChartSeries(data_key="revenue")])
    return app

Built-in Providers

Five ready-made providers you add with a single add_provider() call:

• FileUpload — drag-and-drop file upload with session-scoped storage
