<VersionBadge version="3.2.0" />

Each tile below is a working FastMCP server you can run with `fastmcp dev apps` or connect to from any MCP host. Source lives in `examples/apps/` in the repository.

## Running the examples

Preview any example in your browser with the dev server:

```bash
pip install "fastmcp[apps]"
fastmcp dev apps examples/apps/sales_dashboard/sales_dashboard_server.py
```

The dev UI lets you pick a tool and fill in arguments. In a real deployment the LLM provides those arguments from conversation context — the quiz example especially shines when connected to a host like Goose or Claude Desktop, where the LLM generates the questions itself.

## Standalone apps

### Sales dashboard

A full dashboard with KPI metrics, revenue trends, segment breakdown, and a deal pipeline table. Shows what you can build with a single `app=True` tool and Prefab's chart and data components.

```bash
fastmcp dev apps examples/apps/sales_dashboard/sales_dashboard_server.py
```

### System monitor

Reads live CPU, memory, and disk stats from your machine using `psutil`. Auto-refreshes via `SetInterval` calling a backend tool, with a dropdown to control the refresh rate. The chart accumulates up to 100 data points over time.

```bash
pip install psutil
fastmcp dev apps examples/apps/system_monitor/system_monitor_server.py
```

### Quiz

The LLM generates trivia questions and passes them to the tool. The user answers via buttons, sees correct/incorrect feedback, and tracks score across questions. Demonstrates multi-turn client-side state with FastMCPApp.

```bash
fastmcp dev apps examples/apps/quiz/quiz_server.py
```

### Interactive map

Accepts addresses or place names, geocodes them via OpenStreetMap Nominatim (free, no API key), and renders an interactive Leaflet map using Prefab's `Embed` component with inline HTML. A reminder that Prefab apps can break out of built-in components when they need to.

```bash
fastmcp dev apps examples/apps/map/map_server.py
```
