## Installation

### Prerequisites

- Python 3.8 or higher
- A Zillow Bridge API key (request access at api@bridgeinteractive.com)

### Setup

1. Clone this repository:
   ```
   git clone https://github.com/yourusername/zillow-mcp-server.git
   cd zillow-mcp-server
   ```

2. Install the dependencies:
   ```
   pip install -r requirements.txt
   ```

3. Create a `.env` file with your Zillow API key:
   ```
   ZILLOW_API_KEY=your_zillow_api_key_here
   ```

### Running the Server

Run the server with options:

```bash
# Standard stdio mode (for Claude Desktop)
python zillow_mcp_server.py

# HTTP server mode (for remote access)
python zillow_mcp_server.py --http --port 8000

# Debug mode for more verbose logging
python zillow_mcp_server.py --debug
```

### Docker Deployment

You can also run the server using Docker:

```bash
# Build the Docker image
docker build -t zillow-mcp-server .

# Run with environment variables
docker run -p 8000:8000 -e ZILLOW_API_KEY=your_key_here zillow-mcp-server

# Or using an env file
docker run -p 8000:8000 --env-file .env zillow-mcp-server
```

## Usage with Claude Desktop

Add the Zillow MCP server to your Claude Desktop configuration file:

- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`

```json
{
  "mcpServers": {
    "zillow": {
      "command": "python",
      "args": ["/path/to/zillow_mcp_server.py"]
    }
  }
}
```

For remote HTTP server:

```json
{
  "mcpServers": {
    "zillow-remote": {
      "command": "npx",
      "args": ["mcp-remote", "https://your-mcp-server-url.com/sse"]
    }
  }
}
```

## Available Tools

### Search Properties

```python
search_properties(
    location: str,
    type: str = "forSale",
    min_price: Optional[int] = None,
    max_price: Optional[int] = None,
    beds_min: Optional[int] = None,
    beds_max: Optional[int] = None,
    baths_min: Optional[float] = None,
    baths_max: Optional[float] = None,

    address: str = None
)
```

Example usage in Claude:
```
Can you get the details for the property with ID 12345?
```

### Get Zestimate

    time_period: str = "1year"
)
```

Example usage in Claude:

## Error Handling

The server implements robust error handling with:

- Automatic retries with exponential backoff
- Detailed error logging
- Rate limit handling
- Connection timeouts
- Graceful degradation

## Technical Architecture

This MCP server is built using:

- **FastMCP**: A Pythonic framework for building Model Context Protocol servers
- **Requests**: For making HTTP requests to the Zillow Bridge API with connection pooling and retries
- **Backoff**: For implementing exponential backoff retry logic
- **python-dotenv**: For managing environment variables

The server provides both tools (interactive functions) and resources (static data) that Claude can access to provide real estate information to users.

## Limitations and Considerations

- Zillow's API has usage limits (typically 1,000 requests per day per dataset)
- Zillow's terms of service prohibit storing data locally; all requests must be dynamic
- You must properly attribute data to Zillow in the user interface
- The Bridge API format may change; refer to Zillow's documentation for updates
