## Quick Start

### Installation

```bash
git clone https://github.com/aviveldan/datagov-mcp.git
cd datagov-mcp

# Create virtual environment and install (requires uv)
uv venv
source .venv/bin/activate  # On Windows: .venv\Scripts\activate
uv pip install -e ".[dev]"
```

### Using with Claude Desktop

```bash
fastmcp install claude-desktop server.py
```

Restart Claude Desktop — you'll see the DataGovIL tools available immediately.

### Try It with the MCP Inspector

```bash
fastmcp dev inspector server.py
```

This opens a web UI where you can browse tools, test them interactively, and preview MCP App visualizations in the **Apps** tab.

### Using with `fastmcp dev apps`

Preview the interactive visualization apps locally:

```bash
fastmcp dev apps server.py
```

## Example: Finding Real Estate Opportunities

Here's a real workflow for someone exploring the Israeli housing market:

```
You: "Search for discounted housing lottery datasets"

→ package_search(q="דירה בהנחה")
  Found: "נתונים תקופתיים - תכנית דירה בהנחה" (Discounted Housing Program)
  Resource ID: 7c8255d0-49ef-49db-8904-4cf917586031

You: "Profile this dataset so I can understand what fields are available"

→ dataset_profile(resource_id="7c8255d0-49ef-49db-8904-4cf917586031")
  Shows: LamasName (city), Subscribers, Winners, PriceForMeter,
         LotteryHousingUnits, ProjectName, Neighborhood...

You: "Show me which cities have the most subscribers competing for units"

→ chart_generator(
    resource_id="7c8255d0-49ef-49db-8904-4cf917586031",
    chart_type="bar",
    x_field="LamasName",
    y_field="Subscribers",
    title="Housing Lottery Subscribers by City"
  )
  → Interactive bar chart rendered in MCP Apps UI

You: "Now show the public housing units — map them and show me sizes"

→ dataset_profile(resource_id="c3a68837-9b7a-4ee7-bd92-130678dc8ae3")
  Shows: CityLmsName, NumOfRooms (avg 2.4), Floor, TotalArea (21-110 m²)...

→ chart_generator(
    resource_id="c3a68837-9b7a-4ee7-bd92-130678dc8ae3",
    chart_type="histogram",
    x_field="TotalArea",
    title="Distribution of Housing Unit Sizes (m²)"
  )
  → Most units are 48-57 m², with a long tail up to 110 m²
```

**Insight:** Cities like Ashkelon and Sderot show 25,000-35,000 subscribers per lottery — that's intense competition. Smaller cities in the periphery (Umm al-Fahm, Nazareth) have far fewer. If you're flexible on location, your odds improve dramatically.

| `histogram` | Distribution of numeric values (e.g., apartment sizes) |
| `bar` | Compare categories (e.g., subscribers per city) |
| `line` | Trends over time (e.g., housing units per lottery) |
| `scatter` | Correlations between two numeric fields |

```
chart_generator(

## Architecture

### MCP Apps

Visualization tools use [FastMCPApp](https://gofastmcp.com) providers with [prefab-ui](https://github.com/PrefectHQ/prefab-ui) components:

- **`DataProfile` app** → `DataTable`, `Metric` components
- **`Charts` app** → `BarChart`, `LineChart`, `ScatterChart`, `Histogram`
- **`Maps` app** → `Embed` with Leaflet HTML

Tools registered via `@app.ui()` automatically get proper MCP Apps metadata and render in compatible clients.

### Async HTTP Layer

All API calls use `httpx.AsyncClient` with:
- 30-second timeout
- Automatic retries for 5xx errors
- Connection pooling

### Data Safety

- Numeric values from CKAN are coerced (handles `"25"` → `25.0`)
- Map popup content is HTML-escaped to prevent XSS
- Line charts are sorted by x-axis for correct rendering
