# eonet.events.list

Retrieve natural disaster and extreme weather events tracked by NASA Earth Observatory Natural Event Tracker (EONET). Returns events with geolocation, magnitude, data sources, and category. Supports filtering by status (open=ongoing, closed=resolved), event category (wildfires, severeStorms, volcanoes, earthquakes, floods, etc.), date range, data source, bounding box, and result count. Each event includes one or more geometry points with coordinates and timestamps. Ideal for real-time situational awareness, disaster monitoring, and geospatial analysis. Data sourced from GDACS, JTWC, USGS, IRWIN, FIRMS and 10+ other agencies. No auth required.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `end` | string | no | End date for event filter in ISO 8601 format (YYYY-MM-DD). |
| `bbox` | string | no | Bounding box filter as comma-separated decimal degrees: "minLon,minLat,maxLon,maxLat" (e.g. "-180,-90,180,90" for global). Event must have at least one geometry |
| `days` | integer | no | Return events from the last N days (1–9999). Overrides start/end when provided. |
| `limit` | integer | no | Maximum number of events to return (1–1000). Defaults to 10. |
| `start` | string | no | Start date for event filter in ISO 8601 format (YYYY-MM-DD). |
| `source` | string | no | Filter events by data source ID (e.g. "GDACS", "IRWIN", "JTWC", "PDC"). Multiple sources separated by commas. |
| `status` | string | no | Event status filter: "open" for ongoing events, "closed" for resolved events, "all" for both. Defaults to "open". |

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "eonet.events.list",
    "arguments": {}
  }
}
```

## Why eonet.events.list is rated Low

Tool queries and retrieves public NASA EONET disaster data without modifying, executing code, or financial operations.

From the tool's own definition: "Retrieve natural disaster events, filtering, geolocation, no modification or deletion."

## Use case

AI agents call eonet.events.list to retrieve information from Apibase without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Apibase:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "eonet.events.list": {}
  }
}
```
