WHAT IT DOES

What usgs-eq-query does on Meta Data Mcp

AI agents call usgs-eq-query to retrieve information from Meta Data Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why usgs-eq-query is rated Low

This tool retrieves and filters publicly available earthquake data from the USGS catalog. It has no capability to modify, delete, or execute operations. It returns structured data (GeoJSON) based on query parameters. Even if misused by an AI agent, it only exposes read access to public scientific data with no destructive or financial consequences.

From the tool's definition Tool performs querying of the USGS earthquake catalog with filtering options (time, magnitude, bounding-box). Returns GeoJSON data. The word 'query' combined with the description indicates read-only retrieval of existing data with no side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs usgs-eq-query safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Meta Data Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For usgs-eq-query, this is the rule to start with:

usgs-eq-query Allowed

usgs-eq-query is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "usgs-eq-query": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Meta Data Mcp, apply this rule, and every usgs-eq-query call is checked against it from then on.

Questions about usgs-eq-query

What does the usgs-eq-query tool do? +

Query the USGS FDSN earthquake catalog (GeoJSON). Supports time, magnitude, and bounding-box filters. It is categorised as a Read tool in the Meta Data Mcp MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on usgs-eq-query? +

Register the Meta Data MCP server in PolicyLayer and add a rule for usgs-eq-query: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Meta Data Mcp. Nothing to install.

What risk level is usgs-eq-query? +

usgs-eq-query is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit usgs-eq-query? +

How do I block usgs-eq-query completely? +

Set action: deny in the PolicyLayer policy for usgs-eq-query. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides usgs-eq-query? +

usgs-eq-query is provided by the Meta Data MCP server (pypi:meta-data-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
