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

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

## Why batch_depths is rated Low

This tool retrieves market depth (order book) data in batch, consistent with other read-only market data tools on the server. No side effects, modifications, executions, or financial transactions are implied. Confidence is slightly reduced (0.85) due to empty tool description, but the sibling tool pattern and server context provide strong evidence of read-only data retrieval functionality.

From the tool's own definition: "Tool name 'batch_depths' follows the naming pattern of sibling tools (batch_klines, batch_quotes, batch_ticks, single_depth) which all retrieve market data."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents call batch_depths to retrieve information from Itick 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 Itick:

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