Setup
Prerequisites
- Node.js 18+
- A RedAlert API key (get one at redalert.orielhaim.com)
Configure in Claude Code
Add to ~/.claude.json under your project's mcpServers:
{
"redalert": {
"type": "stdio",
"command": "npx",
"args": ["-y", "redalert-mcp-server"],
"env": {
"REDALERT_API_KEY": "your-api-key-here"
}
}
}
Configure in Claude Desktop
Add to claude_desktop_config.json:
{
"mcpServers": {
"redalert": {
"command": "npx",
"args": ["-y", "redalert-mcp-server"],
"env": {
"REDALERT_API_KEY": "your-api-key-here"
}
}
}
}
Usage Examples
Once configured, you can ask Claude:
- "Show me active alerts right now"
- "Find all missile alerts in Kfar Saba in the last 24 hours"
- "Search for shelters near Tel Aviv"
- "Get alert statistics summary with top cities"
- "Subscribe to test alerts and poll for updates"
- "Compare missile alerts between Kfar Saba and Shoham in the last 2 months"
Example: City Comparison
Prompt: "Compare the missile alerts in the last 2 months between Kfar Saba and Shoham"
┌──────────────────────────┬───────────────┬───────────────┐
│ │ Kfar Saba │ Shoham │
├──────────────────────────┼───────────────┼───────────────┤
│ Zone │ Sharon │ Yarkon │
├──────────────────────────┼───────────────┼───────────────┤
│ Missile alerts │ 64 │ 77 │
├──────────────────────────┼───────────────┼───────────────┤
│ Total alerts (all types) │ 205 │ 217 │
├──────────────────────────┼───────────────┼───────────────┤
│ Last missile alert │ Mar 14, 12:43 │ Mar 13, 21:22 │
└──────────────────────────┴───────────────┴───────────────┘
Shoham had ~20% more missile alerts than Kfar Saba over this period (77 vs 64).
Both cities had a similar ratio of missile alerts to total alerts (~31-35%).
Claude automatically uses get_stats_cities and get_stats_history to gather and compare data across cities.
Example: Weekly Alert Summary (Hebrew)
Prompt: "תראה לי את כל ההתראות שהיו לכפר סבא בשבוע האחרון"
הנה כל ההתראות בכפר סבא בשבוע האחרון (7-14 במרץ):
| תאריך ושעה (UTC) | סוג התראה |
|-------------------|----------------------|
| 14/3, 13:04 | טילים |
| 14/3, 12:43 | טילים |
| 14/3, 12:39 | ידיעה מקדימה |
| 14/3, 00:30 | ידיעה מקדימה |
| 13/3, 21:22 | טילים |
| 13/3, 17:31 | טילים |
| 13/3, 17:26 | ידיעה מקדימה |
| 13/3, 14:58 | ידיעה מקדימה |
| 13/3, 11:26 | ידיעה מקדימה |
| 13/3, 08:49 | חדירת כלי טיס עוין |
| 12/3, 19:42 | טילים |
| 12/3, 19:38 | ידיעה מקדימה |
| 12/3, 15:19 | חדירת כלי טיס עוין |
| 12/3, 13:03 | טילים |
| 12/3, 12:57 | ידיעה מקדימה |
| 12/3, 07:22 | ידיעה מקדימה |
| 12/3, 02:13 | טילים |
| 12/3, 02:07 | ידיעה מקדימה |
סיכום השבוע בכפר סבא:
- 8 התראות טילים
- 8 ידיעות מקדימות
- 2 חדירות כלי טיס עוין
Claude uses get_stats_history with Hebrew city search, automatically filtering results to show only Kfar Saba. Works in any language.
Example: Nearest Shelters
Prompt: "תראה לי את שלושת המקלטים הכי קרובים לתיאטרון הבימה בתל אביב"
שלושת המקלטים הקרובים ביותר לתיאטרון הבימה:
| # | מרחק | כתובת | שם | סוג | שטח |
|---|--------|---------------------------|----------------------|----------------------|-----------|
| 1 | 143 מ' | הוברמן 4 (כיכר הבימה) | הבימה/שד' בן ציון | מקלט בשטח חניון | 2,000 מ"ר |
| 2 | 154 מ' | הוברמן 1 | היכל התרבות | חניון מחסה לציבור | 37,200 מ"ר|
| 3 | 260 מ' | ביל"ו 54 | - | מקלט ציבורי | 92 מ"ר |
- מקלט 1 - ממש בכיכר הבימה, גישה ציבורית
- מקלט 2 - היכל התרבות, החניון הגדול משמש כמחסה לציבור
- מקלט 3 - ביל"ו 54 פינת מרמורק 20, מתחת לבית כנסת
Claude resolves the landmark to coordinates and uses search_shelters to find the nearest shelters with full details.
