## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why get_protocols is rated Low

This tool performs a simple data retrieval operation ('List all protocols') and returns informational metrics (TVL values). It has no side effects, does not execute code, does not modify data, and does not involve financial transactions. The read-only nature and low blast radius (retrieving public DeFi protocol statistics) clearly place it in the Read category with low severity.

From the tool's own definition: "Tool name 'get_protocols' and description 'List all protocols on defillama along with their tvl' indicate a query operation that retrieves and displays data without modification."

## Use case

AI agents call get_protocols 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_protocols": {}
  }
}
```
