WHAT IT DOES

What getSupportedNetworks does on MCP Ethers Wallet

AI agents call getSupportedNetworks 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 getSupportedNetworks is rated Low

This is a straightforward read-only query tool that retrieves static configuration data about blockchain networks. It performs no mutations, executions, financial operations, or destructive actions. The low severity reflects minimal blast radius if misused by an AI agent—an attacker gains only informational content about available networks, which is typically public data.

From the tool's definition Tool description states 'Get a list of all supported networks and their configurations' — a retrieval operation with no side effects. It queries and returns network metadata.

RECOMMENDED RULE

The rule that runs getSupportedNetworks 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 getSupportedNetworks, this is the rule to start with:

getSupportedNetworks Allowed

getSupportedNetworks 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": {
    "getSupportedNetworks": {}
  }
}

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 getSupportedNetworks call is checked against it from then on.
