## Why get_onchain_fg is rated Low

This tool retrieves and aggregates market intelligence metrics from an existing node. It performs data aggregation and analysis (read-only) with no side effects.

From the tool's own definition: "Tool description states 'Get proprietary On-Chain Fear & Greed Index' — a retrieval operation that queries data (CDD, mempool pressure, hashrate trend, whale volume) from the server's own Bitcoin Core node."

## Use case

AI agents call get_onchain_fg to retrieve information from Crypto Intelligence without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
