Why getAddressInternalTransactions needs a policy

This tool performs read-only retrieval of transaction data from the Ethereum blockchain. It queries existing internal transactions and contract calls without creating, modifying, deleting, or executing any operations. The data retrieved is immutable historical information.

From the tool's definition Tool name 'getAddressInternalTransactions' and description explicitly state it 'Get[s] internal (trace-level) transactions for an address' — a query operation that retrieves historical blockchain data with no side effects or modifications.

POLICY

How to control getAddressInternalTransactions

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

policy.json

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

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