## Why get_statistics is rated Low

This tool retrieves aggregate statistics—immutable, already-computed metrics—from a public financial data source. There are no side effects, no data modification, no code execution, and no financial transactions. The blast radius of misuse is minimal since the data is public and the tool cannot alter system or market state. Severity is low because querying public statistics poses no operational or financial risk.

From the tool's own definition: "Tool name 'get_statistics' and description 'Get aggregate platform statistics (volume, open interest, etc.)' indicate a query operation that retrieves existing data without modification."

## Use case

AI agents call get_statistics to retrieve information from Derive MCP Server 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 Derive MCP Server:

```json
