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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "price",
    "arguments": {}
  }
}

## Why price is rated Low

This tool performs a read-only query of cryptocurrency market data. It retrieves publicly available information (price, market cap, volume) with no side effects, no code execution, no data modification, and no financial transactions. The blast radius of misuse is minimal—an agent could only retrieve data it is not authorized to see, but cannot execute harmful operations, delete data, or move money.

From the tool's own definition: "Tool name 'price' and description 'Get the current price, 24h change, market cap, and volume for any cryptocurrency' indicate a query operation that retrieves real-time market data without modifying or executing anything."

## Use case

AI agents call price to retrieve information from Cryptosense 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 Cryptosense:

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