## Why get_v2_chains is rated Low

This tool retrieves (gets) current TVL metrics for all chains. It performs a read-only query operation with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—an agent could only retrieve publicly available DeFi data, which carries no financial, destructive, or system-level risk.

From the tool's own definition: "Tool name 'get_v2_chains' and description 'Get current TVL of all chains' indicates a retrieval operation that queries blockchain TVL data without modifying state."

## Use case

AI agents call get_v2_chains to retrieve information from Defillama without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Defillama:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_v2_chains": {}
  }
}
