+- Line length: 100 characters
+- Use double quotes for strings
+- Follow PEP 8 conventions
+
+### Formatting
+
+```bash
+# Auto-format all code
+ruff format .
+```
+
+### Linting
+
+```bash
+# Check for issues
+ruff check .
+
+# Auto-fix issues
+ruff check . --fix
+```
+
+### Type Hints
+
+Use type hints for function signatures:
+
+```python
+from typing import List, Optional
+from nadlan_mcp.govmap.models import Deal
+
+def process_deals(
+    deals: List[Deal],
+    min_price: Optional[float] = None
+) -> List[Deal]:
+    """Process and filter deals."""
+    ...
+```
+
+## Testing Guidelines
+
+### Test Structure
+
+```
+tests/
+├── govmap/          # Unit tests for govmap package
+├── e2e/             # End-to-end integration tests
+└── api_health/      # API health monitoring (weekly)
+```
+
+### Writing Tests
+
+```python
+import pytest
+from nadlan_mcp.govmap.models import Deal
+
+class TestYourFeature:
+    """Test cases for your feature."""
+
+    @pytest.fixture
+    def sample_deals(self):
+        """Create sample test data."""
+        return [
+            Deal(objectid=1, deal_amount=1000000, deal_date="2024-01-01"),
+            Deal(objectid=2, deal_amount=1500000, deal_date="2024-02-01"),
+        ]
+
+    def test_basic_functionality(self, sample_deals):
+        """Test basic functionality."""
+        result = your_function(sample_deals)
+        assert len(result) == 2
+```
+
+### Test Coverage
+
+Aim for **>80% coverage** for new code:
+
+```bash
+pytest --cov=nadlan_mcp --cov-report=html
+open htmlcov/index.html
+```
+
+### Running Different Test Suites
+
+```bash
+# Fast tests only (default, ~12s)
+pytest tests/ -m "not api_health" -q
+
+# Integration tests (makes real API calls)
+pytest -m integration -v
+
+# API health checks (weekly)
+pytest -m api_health -v
+
+# Specific test file
+pytest tests/govmap/test_filters.py
+```
+
+## Architecture Guidelines
+
+### Package Structure
+
+```
+nadlan_mcp/
+├── govmap/              # Core business logic
+│   ├── models.py        # Pydantic data models

+```
+
+### Design Principles
+
+1. **MCP provides data, LLM provides intelligence**
+   - Keep analysis simple in MCP layer
+   - Let LLM interpret and reason about data
+
+2. **Return Pydantic models, not dicts**
+   - All API methods return typed models
+   - Use `.model_dump()` to serialize for JSON
+
+3. **Separation of concerns**
+   - `client.py` - API calls only
+   - `filters.py` - Filtering logic
+   - `statistics.py` - Calculations
+   - `market_analysis.py` - Analysis functions
+
+4. **Backward compatibility**
+   - Use `govmap/__init__.py` for public exports
+   - Maintain existing function signatures
+
+### Adding New Features
+
+#### 1. Add Pydantic Model (if needed)
+
+```python

+# Deployment Guide
+
+This guide covers deploying Nadlan-MCP as an MCP server for AI agents.
+
+## Prerequisites
+
+- Python 3.10 or higher
+- pip package manager
+- MCP-compatible client (Claude Desktop, etc.)
+
+## Installation
+
+### 1. Clone and Setup
+
+```bash
+git clone <repository-url>
+cd nadlan-mcp
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+pip install -r requirements.txt
+```
+
+### 2. Verify Installation
+
+```bash
+# Test the library
+python -c "from nadlan_mcp.govmap import GovmapClient; print('✓ Installation successful')"
+
+# Test the MCP server
+python run_fastmcp_server.py
+```
+
+## Deployment Options
+
+### Option 1: Claude Desktop (Recommended)
+
+Add to your Claude Desktop MCP configuration file:
+
+**macOS:** `~/Library/Application Support/Claude/claude_desktop_config.json`
+**Windows:** `%APPDATA%\Claude\claude_desktop_config.json`
+
+```json
+{
+  "mcpServers": {
+    "nadlan-mcp": {
+      "command": "python",
+      "args": ["/absolute/path/to/nadlan-mcp/run_fastmcp_server.py"],
+      "env": {}
+    }
+  }
+}
+```
+
+**Important:** Use absolute paths, not relative paths.
+
+Restart Claude Desktop to load the server.
+
+### Option 2: Custom MCP Client
+
+Use stdio transport to connect:
+
+```python
+import asyncio
+from mcp.client.stdio import stdio_client
+
+async def main():
+    async with stdio_client([
+        "python",
+        "/path/to/nadlan-mcp/run_fastmcp_server.py"
+    ]) as client:
+        # List available tools
+        result = await client.list_tools()
+        print("Tools:", [t.name for t in result.tools])
+
+        # Call a tool
+        result = await client.call_tool(
+            "find_recent_deals_for_address",
+            {"address": "רוטשילד 1 תל אביב", "years_back": 2}
+        )
+        print(result)
+
+asyncio.run(main())
+```
+
+### Option 3: Direct Python Usage
+
+Use as a library without MCP:
+
+```python
+from nadlan_mcp.govmap import GovmapClient
+
+client = GovmapClient()
+deals = client.find_recent_deals_for_address("תל אביב רוטשילד 1", years_back=2)
+print(f"Found {len(deals)} deals")
+```
+
+## Configuration
+
+### Environment Variables
+
+Create `.env` file (optional):
+
+```bash
+# API Settings
+GOVMAP_BASE_URL=https://www.govmap.gov.il/api/
+GOVMAP_USER_AGENT=NadlanMCP/2.0.0
+
+# Timeouts (seconds)
+GOVMAP_CONNECT_TIMEOUT=10
+GOVMAP_READ_TIMEOUT=30
+
+# Retry Settings
+GOVMAP_MAX_RETRIES=3
+GOVMAP_RETRY_MIN_WAIT=1
+GOVMAP_RETRY_MAX_WAIT=10
+
+# Rate Limiting
+GOVMAP_REQUESTS_PER_SECOND=5.0
+
+# Performance
+GOVMAP_MAX_POLYGONS=10
+```
+
+### Programmatic Configuration
+
+```python
+from nadlan_mcp.config import GovmapConfig, set_config
+
+config = GovmapConfig(
+    connect_timeout=15,
+    read_timeout=45,
+    max_retries=5,
+    requests_per_second=3.0
+)
+set_config(config)
+```
+
+## Verification
+
+### Test MCP Tools
+
+In Claude Desktop or your MCP client, try:
+
+```
+Find recent real estate deals for רוטשילד 1 תל אביב
+```
+
+Or use the test script:
+
+```bash
+python -m pytest tests/e2e/test_mcp_tools.py -v
+```
+
+### Check Logs
+
+Enable debug logging:
+
+```python
+import logging
+logging.basicConfig(level=logging.DEBUG)
+```
+
+## Troubleshooting
+
+### Server Won't Start
+
+**Problem:** `ImportError` or `ModuleNotFoundError`
+
+**Solution:**
+```bash
+# Ensure all dependencies installed
+pip install -r requirements.txt
+
+# Verify Python version
+python --version  # Should be 3.10+
+```
+
+### Claude Desktop Not Finding Server
+
+**Problem:** Server doesn't appear in Claude Desktop
+
+**Solution:**
+1. Check config file path is correct for your OS
+2. Use **absolute paths** in configuration
+3. Restart Claude Desktop after config changes
+4. Check Claude Desktop logs for errors
+
+### API Errors
+
+**Problem:** `requests.exceptions.ConnectionError`
+
+**Solution:**
+- Check internet connection
+- Verify Govmap API is accessible: `curl https://www.govmap.gov.il/api/`
+- Check firewall/proxy settings
+
+**Problem:** `429 Too Many Requests`
+
+**Solution:**
+- Reduce `GOVMAP_REQUESTS_PER_SECOND` (default: 5)
+- Add delays between requests
+
+### No Results Found
+
+**Problem:** `No deals found for this address`
+
+**Solution:**
+- Use Hebrew address format: "רוטשילד 1 תל אביב"
+- Increase search radius (default: 50m)
+- Extend time period: `years_back=5`
+
+## Performance Optimization
+
+### For Production Use
+
+1. **Increase timeouts** for slow networks:
+   ```bash
+   GOVMAP_READ_TIMEOUT=60
+   ```
+
+2. **Adjust rate limiting** based on your needs:
+   ```bash
+   GOVMAP_REQUESTS_PER_SECOND=3.0  # More conservative
+   ```
+
+3. **Limit polygon queries** to improve speed:
+   ```bash
+   GOVMAP_MAX_POLYGONS=5  # Fewer API calls
+   ```
+
+### Monitoring
+
+```python
+import logging
+
+# Enable info logging
+logging.basicConfig(
+    level=logging.INFO,
+    format='%(asctime)s - %(name)s - %(levelname)s - %(message)s'
+)
+```
+
+## Updates
+
+### Updating Nadlan-MCP
+
+```bash
+cd nadlan-mcp
+git pull
+source venv/bin/activate
+pip install -r requirements.txt --upgrade
+```
+
+Restart your MCP client to load the updated server.
+
+## Security Considerations
+
+1. **No API Keys Required:** Govmap API is public, no authentication needed
+2. **Rate Limiting:** Built-in to respect API limits
+3. **Input Validation:** All user inputs are validated before API calls
+4. **No Data Storage:** No user data is stored or cached
+
+## Support
+
+- **Issues:** Create issue at repository
+- **Documentation:** See README.md, ARCHITECTURE.md
+- **Examples:** See `examples/` directory
+
+---
+
+**Note:** Nadlan-MCP uses the public Israeli government Govmap API. Please respect rate limits and terms of service.
