WHAT IT DOES

What getContractCode does on MCP Ethers Wallet

AI agents call getContractCode to retrieve information from MCP Ethers Wallet without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why getContractCode is rated Low

Retrieving contract code is a read-only operation that queries blockchain state without modifying data, executing arbitrary code, or producing side effects. It mirrors blockchain explorers' 'view contract code' functionality. While the description is empty (reducing confidence slightly), the tool name and server context make the read classification clear.

From the tool's definition Tool name 'getContractCode' indicates retrieval of smart contract bytecode or source code from the blockchain.

RECOMMENDED RULE

The rule that runs getContractCode safely

getContractCode Allowed

getContractCode is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect MCP Ethers Wallet, apply this rule, and every getContractCode call is checked against it from then on.
