Pikud Haoref Real-Time Alert System

System Architecture

A comprehensive middleware service and MCP server for accessing Israeli emergency alerts from the official Pikud Haoref (Israeli Home Front Command) API.

Overview

This project provides two ways to access Israeli emergency alert data using a publish-subscribe architecture:

FastAPI Middleware Service - Single source polling with real-time SSE streaming
MCP Server - Event-driven subscriber for AI assistants (built with FastMCP)

The FastAPI service polls the official Pikud Haoref API at https://www.oref.org.il/WarningMessages/alert/alerts.json and publishes alerts via Server-Sent Events. The MCP server subscribes to this stream, creating an efficient pub-sub system that eliminates duplicate API calls while providing real-time access to emergency alerts including rocket alerts, aerial intrusions, earthquakes, and other emergencies.

Features

FastAPI Service Features

Single-source polling of emergency alerts (eliminates duplicate API calls)
Real-time SSE streaming via public webhook endpoint
API key authentication for client endpoints and geo-restriction to Israel
Docker support for easy deployment
Comprehensive testing suite

MCP Server Features

Event-driven SSE client - Subscribes to FastAPI webhook for real-time alerts
3 Tools for AI assistants:
- check_current_alerts - Check for active alerts from subscribed stream
- get_alert_history - Get recent alerts with filtering (limit: 1-50, region filter, intelligent city matching)
- get_connection_status - Check SSE subscription connection status
2 Resources:
- poha://alerts/recent - JSON data of recent alerts
- poha://alerts/current-status - System status information
Smart City Filtering:
- Exact substring matching - Find alerts by city name (e.g., "תל אביב" matches all Tel Aviv areas)
- Fuzzy matching - Intelligent matching with threshold 60 for partial/similar names
- Multi-city support - Search multiple cities simultaneously
- Hebrew city names - Optimized for Hebrew location names from the API
Built with FastMCP following proven patterns
Automatic reconnection and error handling for SSE connections

Quick Start

Option 1: FastAPI Service (Requires API Key)

Install dependencies:

pip install -r requirements.txt

Configure environment (create .env file):

API_KEY=your-secure-api-key-here # Required for FastAPI SSE endpoints GEOIP_DB_PATH=/path/to/GeoLite2-Country.mmdb # Optional for geo-restriction

Run the service:

# Start all 3 services with Docker (API:8000, MCP:8001, SSE:8002) make up # View logs in real-time make logs # Check status make status

Connect to the stream:

curl -H "X-API-Key: your-key" http://localhost:8000/api/alerts-stream

Option 2: MCP Server (No API Key Required)

Install dependencies:

pip install -r requirements.txt

Configure your MCP client (Claude Desktop, etc.):

For Claude Desktop, add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{ "mcpServers": { "poha-alerts": { "type": "http", "url": "http://127.0.0.1:8001/mcp" } } }

Cursor IDE, add to .cursor/mcp.json in your project:

{ "mcpServers": { "poha-alerts": { "type": "http", "url": "http://127.0.0.1:8001/mcp" } } }

Start the services:

# Start all 3 services (FastAPI:8000 + MCP:8001 + SSE Gateway:8002) make up # Alternative: Individual service management make app-restart # Restart just FastAPI make mcp-restart # Restart just MCP server make logs-app # View FastAPI logs only make logs-mcp # View MCP server logs only

Access URLs after startup:

FastAPI + Swagger UI: http://localhost:8000/docs
MCP Server: http://localhost:8001/mcp
SSE Gateway: http://localhost:8002

Start using - The server will be available as "Pikud Haoref Alert System" in your MCP client via HTTP transport.

API Endpoints (FastAPI Service)

`GET /`

Basic status endpoint.

`GET /api/alerts-stream`

Headers: X-API-Key: your-key

Server-Sent Events stream for real-time alerts (authenticated endpoint). Returns:

event: new_alert - When a new alert is detected
: keep-alive - Periodic keep-alive messages

`GET /api/webhook/alerts`

Headers: X-API-Key: your-key

Internal SSE webhook endpoint for services like the MCP server. Streams the same alert data as the client endpoint and requires the same API key authentication for security. Designed for server-to-server communication.

Example response for both endpoints:

event: new_alert data: {"id": "12345", "data": ["Tel Aviv", "Ramat Gan"], "cat": "1", "title": "Rocket Alert", "desc": "Immediate shelter required"} : keep-alive

MCP Tools Usage

Check Current Alerts

Use the check_current_alerts tool to see if there are any active emergency alerts from the subscribed SSE stream.

Get Alert History MCP

Use get_alert_history with limit=5 to get the 5 most recent alerts from the API. Use get_alert_history with region="Tel Aviv" to get alerts for a specific region. Use get_alert_history with cities=["תל אביב"] to get alerts for Tel Aviv (all areas). Use get_alert_history with cities=["תל אביב", "חיפה"] to get alerts for multiple cities. Use get_alert_history with cities=["תל אביב מרכז"] for specific areas with fuzzy matching.

City Filtering Examples:

cities=["תל אביב"] - Finds all Tel Aviv areas (דרום העיר ויפו, מזרח, מרכז העיר, עבר הירקון)
cities=["חיפה"] - Finds all Haifa-related alerts
cities=["תל אביב", "חיפה", "ירושלים"] - Multiple cities simultaneously
cities=["תל אביב מרכז"] - Fuzzy matches to "תל אביב - מרכז העיר"
cities=["all"] - No city filtering (shows all alerts)

Check Connection Status

Use get_connection_status to verify the SSE subscription connection and see system health.

Architecture

The system uses a publish-subscribe architecture with the following components:

Pikud Haoref API - External data source (government emergency alerts)
FastAPI Middleware - Single source polling + SSE publisher (polls every 2 seconds)
MCP Server - SSE subscriber + tool provider for AI assistants
Client Applications - Web frontends, mobile apps, AI assistants, or other services

Pikud Haoref API ←→ [Single Poller] ←→ FastAPI Middleware ←→ [SSE Stream] ←→ MCP Server → AI Assistants ↓ [SSE Stream] ←→ Web Clients

Key Benefits:

✅ 50% reduction in API calls (single polling source)
✅ Real-time propagation of alerts via SSE
✅ Event-driven architecture for better scalability
✅ Automatic reconnection for robust SSE connections

Security Features

API Key Authentication (Required for All Endpoints)

Important: API key authentication is required for both SSE endpoints for security.

Both SSE endpoints require API key authentication via X-API-Key header
MCP server connects with authentication to the internal webhook endpoint
Same API key used for both client and internal service authentication

Geo-Restriction (Optional)

Configure GEOIP_DB_PATH to restrict access to Israeli IP addresses only:

Sign up at MaxMind
Download GeoLite2-Country.mmdb
Set GEOIP_DB_PATH in your .env file

Troubleshooting

Common Issues

"API key is missing" - Ensure X-API-Key header is set for both client and webhook endpoints
MCP connection fails - Check:
- Python path in MCP config (use full venv path if needed: /path/to/venv/bin/python)
- API_KEY environment variable is set correctly
- FastAPI service is running on localhost:8000
- Restart your MCP client (Cursor, Claude Desktop, etc.)
- Alternative: Use the provided start_mcp.sh script as the command
Connection timeouts - Check your internet connection and firewall settings
Geo-restriction errors - Verify GeoLite2-Country.mmdb path and file permissions
SSE authentication fails - Verify API key matches between FastAPI service and MCP config
City filtering not working -
- Use Hebrew city names (e.g., "תל אביב" not "Tel Aviv")
- Check exact city names in alert history first: cities=["all"]
- Try broader names for fuzzy matching: "תל אביב" instead of "תל אביב - מרכז העיר"
ModuleNotFoundError: No module named 'fuzzywuzzy' -
- Rebuild Docker containers: docker-compose build --no-cache
- Install dependencies: pip install fuzzywuzzy python-Levenshtein
