Returns the amount of transaction fees paid to miners per day.
AI agents call stats__dailytxnfee to retrieve information from Etherscan MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves aggregated historical data about transaction fees from the Ethereum blockchain. It performs no state changes, does not execute code or transactions, and cannot move funds or delete data. The read-only nature of querying statistical blockchain data, combined with the low impact of accessing this information, results in a 'low' severity classification.
From the tool's definition Tool name 'stats__dailytxnfee' and description 'Returns the amount of transaction fees paid to miners per day' indicate a query operation that retrieves historical blockchain statistics without modifying any data or executing transactions.
Documented attack patterns abuse exactly the kind of access stats__dailytxnfee gives an agent:
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__dailytxnfee:
{
"version": "1",
"default": "deny",
"tools": {
"stats__dailytxnfee": {}
}
}stats__dailytxnfee is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Returns the amount of transaction fees paid to miners per day. It is categorised as a Read tool in the Etherscan MCP MCP Server, which means it retrieves data without modifying state.
Register the Etherscan MCP server in PolicyLayer and add a rule for stats__dailytxnfee: 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 Etherscan MCP. Nothing to install.
stats__dailytxnfee is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the stats__dailytxnfee rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for stats__dailytxnfee. 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.
stats__dailytxnfee is provided by the Etherscan MCP server (xiaok/etherscan-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Etherscan MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
