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.

Google ADK natively supports USGS Earthquakes as an MCP tool provider — declare the Vinkius Edge URL and the framework handles discovery, validation, and execution automatically. Combine 3 tools with Gemini's long-context reasoning for complex multi-tool workflows, with production-ready session management and evaluation built in.

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

Why Use Google ADK with the USGS Earthquakes MCP Server

Google ADK provides unique advantages when paired with USGS Earthquakes through the Model Context Protocol.

Google ADK natively supports MCP tool servers — declare a tool provider and the framework handles discovery, validation, and execution

Built on Gemini models, ADK provides long-context reasoning ideal for complex multi-tool workflows with USGS Earthquakes

Production-ready features like session management, evaluation, and deployment come built-in — not bolted on

Seamless integration with Google Cloud services means you can combine USGS Earthquakes tools with BigQuery, Vertex AI, and Cloud Functions

USGS Earthquakes + Google ADK Use Cases

Practical scenarios where Google ADK combined with the USGS Earthquakes MCP Server delivers measurable value.

Enterprise data agents: ADK agents query USGS Earthquakes and cross-reference results with internal databases for comprehensive analysis

Multi-modal workflows: combine USGS Earthquakes tool responses with Gemini's vision and language capabilities in a single agent

Automated compliance checks: schedule ADK agents to query USGS Earthquakes regularly and flag policy violations or configuration drift

Internal tool platforms: build self-service agent platforms where teams connect their own MCP servers including USGS Earthquakes

USGS Earthquakes MCP Tools for Google ADK (3)

These 3 tools become available when you connect USGS Earthquakes to Google ADK via MCP:

count_earthquakes

Get the total count of earthquakes matching specific criteria

get_significant_30_days

No parameters needed. Get highly significant global earthquakes from the last 30 days

query_earthquakes

Use parameters like starttime, endtime, minmagnitude, and geographic boundaries (latitude/longitude/maxradiuskm) to narrow the search. Maximum 20,000 events returned per query. Search for global earthquakes using USGS real-time seismic data

Example Prompts for USGS Earthquakes in Google ADK

Ready-to-use prompts you can give your Google ADK agent to start working with USGS Earthquakes immediately.

"Show me the most significant earthquakes in the world from the last 30 days."

"Count the number of earthquakes above magnitude 2.5 in California in 2023."

"Check if there are any current tsunami warnings globally."

USGS Earthquakes + Google ADK FAQ

Common questions about integrating USGS Earthquakes MCP Server with Google ADK.

How does Google ADK connect to MCP servers?

Import the MCP toolset class and pass the server URL. ADK discovers and registers all tools automatically, making them available to your agent's tool-use loop.

Can ADK agents use multiple MCP servers?

Yes. Declare multiple MCP tool providers in your agent configuration. ADK merges all tool schemas and the agent can call tools from any server in a single turn.

Which Gemini models work best with MCP tools?

Gemini 2.0 Flash and Pro models both support function calling required for MCP tools. Flash is recommended for latency-sensitive use cases, Pro for complex reasoning.
