RISK

Why defi is rated Low

This tool queries and returns read-only data about DeFi protocol statistics (Total Value Locked, blockchain chain, category). While it relates to financial protocols, the tool itself does not move money, execute trades, or modify state—it only fetches and displays publicly available market data. The per-call cost is a platform fee, not a financial effect of the tool itself.

From the tool's definition Tool description states 'Returns live protocol TVL + chain + category from DefiLlama' — purely a data retrieval operation querying public protocol metrics. No modification, deletion, or financial transaction capability.

RECOMMENDED RULE

The rule that runs defi safely

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

defi Allowed

defi 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": {
    "defi": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Omnicall — Agent Tools Gateway, apply this rule, and every defi call is checked against it from then on.
