Is an API key required?

No! The USGS FDSNWS Event API is completely open and requires zero authentication, making this one of the most accessible and powerful real-time data sources available.

What is the query limit?

The maximum number of events returned per single API query is 20,000. If your time range or boundaries are too wide, the API will fail. Use the `count` tool first on large searches.

How fast is the data updated?

The USGS typically updates its earthquake data within minutes of an event occurring, making it one of the most reliable sources for near real-time seismic alerts.

About USGS Earthquakes MCP Server

The USGS Earthquakes MCP Server brings planet-scale telemetry directly to your AI agent. Pulling strictly real-time and historical data from the United States Geological Survey (USGS) API, this tool gives you instant visibility into everything from micro-tremors to catastrophic seismic events globally.

LangChain's ecosystem of 500+ components combines seamlessly with USGS Earthquakes through native MCP adapters. Connect 3 tools via the Vinkius and use ReAct agents, Plan-and-Execute strategies, or custom agent architectures — with LangSmith tracing giving full visibility into every tool call, latency, and token cost.

Core Capabilities

Global Seismic Monitoring — Query real-time data across the planet.
Radial & Bounding Box Search — Focus searches on specific fault lines, continents, or specific radial points like Tokyo or San Francisco.
Magnitude & Time Filters — Zero in on data by slicing through specific date ranges and Richter thresholds.
High-Alert Diagnostics — Detect immediate tsunami warnings and review detailed human-curated significance ratings.

Whether you are building environmental response bots or running historical data analytics on tectonic shifts, this zero-auth integration puts the pulse of the planet in your hands.

The USGS Earthquakes MCP Server exposes 3 tools through the Vinkius. Connect it to LangChain in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
