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

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

## Why market_overview is rated Low

The tool retrieves market intelligence data (prices, trends, overview) without modifying, deleting, or executing external operations. This is a read-only data query. Severity is low because market data retrieval poses minimal risk even if misused by an agent. Confidence is reduced to 0.85 rather than higher because the tool description itself is empty, requiring inference from context and server purpose.

From the tool's own definition: "Tool name 'market_overview' and server description indicate retrieval of crypto market data. Description states 'Get prices, trending coins, market overview' — query/retrieval operations with no side effects."

## Use case

AI agents call market_overview 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": {
    "market_overview": {}
  }
}
```
