Why transaction__gettxreceiptstatus needs a policy

This tool queries blockchain data to return transaction receipt status (a boolean/enum indicating success/failure). It performs no writes, deletions, code execution, or financial operations. It is a read-only retrieval of immutable blockchain state information.

From the tool's definition Tool name 'gettxreceiptstatus' and description 'Returns the status code of a transaction execution' indicate a pure query operation that retrieves transaction metadata without modifying state.

POLICY

How to control transaction__gettxreceiptstatus

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 transaction__gettxreceiptstatus:

policy.json

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

transaction__gettxreceiptstatus 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.
