WHAT IT DOES

What parseEther does on MCP Ethers Wallet

AI agents call parseEther 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 parseEther is rated Low

parseEther in ethers.js is a pure conversion/formatting utility — it does not interact with the blockchain, move funds, or modify state. It simply parses a string value into Wei units. No description was provided to contradict this interpretation, so confidence is moderate. Classified as Read (lowest severity) since it's a local computation with no external side effects.

From the tool's definition Tool name: parseEther — no description provided. Based on the name, 'parseEther' is a standard utility function (common in ethers.js) that converts a human-readable Ether value (e.g., '1.5') into its Wei representation (bigint).

RECOMMENDED RULE

The rule that runs parseEther safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MCP Ethers Wallet, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For parseEther, this is the rule to start with:

parseEther Allowed

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

View as policy code

policy.json

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

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 parseEther call is checked against it from then on.
