StormAxis MCP Server

Give your AI agent real-time US storm intelligence. StormAxis connects Claude, GPT, and any MCP-compatible agent to live NOAA storm data, scored contractor opportunities, property targeting lists, and canvass route optimization — purpose-built for roofing and restoration contractors.

---

What it does

StormAxis watches every storm in the United States in real time. When a qualifying hail or wind event hits, it automatically scores it (0–100) based on severity, local property values, roof age, and historical claim rates — then surfaces the best opportunities to your agent.

Your AI agent can:

• Ask "What are the best storm opportunities in Texas right now?" and get a ranked list with estimated revenue
• Pull a property target list for any ZIP code hit by a scored storm
• Get H3-optimized canvass clusters so field crews know exactly where to knock doors first
• Check insurance claim propensity by state before committing resources to a new market
• Subscribe to webhooks that fire the moment a qualifying storm lands in your territory

Quickstart

1. Get a Partner API key

Sign up at stormaxis.io/partner. MCP access requires Growth tier ($199/mo) or above.

2. Add to Claude Code

claude mcp add stormaxis \
  --transport sse \
  --url https://stormaxis.io/api/mcp/sse \
  --header "X-API-Key: YOUR_API_KEY"

3. Make your first call

Ask Claude: "Check the StormAxis pipeline status."

You should see pipeline_active: true and a latest_event_time within the last 48 hours. You're live.

      }
    }
  }
}

Standalone npm server (stdio)

npm install -g stormaxis-mcp

Add to claude_desktop_config.json:

Prompts

The server ships two pre-built prompt templates that chain multiple tools into a single natural-language request:

Prompt	Arguments	Description
storm_assessment	state (default: TX)	Full briefing: overview → top opportunities → score breakdown → property targeting
property_search	zip_code (default: 76109)	Find older-roof properties in a ZIP with active storm context
