Why stats__dailynetutilization needs a policy

This tool retrieves aggregated, read-only blockchain statistics (daily gas utilization metrics) from Etherscan's public data. It has no side effects, cannot modify state, and provides informational data that is already public. The blast radius of misuse is minimal—an agent could only retrieve potentially redundant or stale statistics about network conditions.

From the tool's definition Tool name 'stats__dailynetutilization' and description 'Returns the daily average gas used over gas limit, in percentage' indicate a query operation that retrieves historical blockchain statistics. No modification, deletion, or execution of code is described.

POLICY

How to control stats__dailynetutilization

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

policy.json

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

stats__dailynetutilization 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 Etherscan MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
