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.

Claude Desktop is the definitive way to connect USGS Earthquakes to your AI workflow. Add the Vinkius Edge URL to your config, restart the app, and Claude immediately exposes all 3 tools in the chat interface — ask a question, Claude calls the right tool, and you see the answer. Zero code, zero context switching.

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 Claude Desktop in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

USGS Earthquakes + Claude Desktop FAQ

Common questions about integrating USGS Earthquakes MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully — if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL — Claude auto-negotiates the transport protocol.
