WHAT IT DOES

What getTokensBalance does on Ethereum Tools

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

RISK

Why getTokensBalance is rated Low

The 'get' prefix combined with 'Balance' strongly suggests this tool retrieves token balance information from the blockchain without modifying state. Although the description is empty, the naming pattern and server context (wallet analysis, on-chain data retrieval) indicate a read-only query operation. No side effects, no irreversible actions, no code execution, and no financial transactions are implied.

From the tool's definition Tool name 'getTokensBalance' indicates a retrieval operation (get + query). Contextually, this is part of an Ethereum analysis toolkit focused on blockchain data retrieval.

RECOMMENDED RULE

The rule that runs getTokensBalance safely

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

getTokensBalance Allowed

getTokensBalance 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": {
    "getTokensBalance": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Ethereum Tools, apply this rule, and every getTokensBalance call is checked against it from then on.
