Why eia_natural_gas_storage needs a policy

This tool retrieves historical and current natural gas storage metrics from EIA databases. It performs read-only operations (Get) on public energy infrastructure data. There are no side effects, data modifications, financial transactions, code execution, or destructive operations. The tool is part of a data access API for publicly available U.S.

From the tool's definition Tool description states 'Get natural gas storage data including inventory levels, injections, and withdrawals' — purely retrieves and queries existing data with no modification, deletion, or execution capabilities.

POLICY

How to control eia_natural_gas_storage

PolicyLayer is an MCP gateway — it sits between your AI agents and EIA MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for eia_natural_gas_storage:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "eia_natural_gas_storage": {}
  }
}

eia_natural_gas_storage is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register EIA MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
