## Why alpha_get_orderbook is rated Low

This tool retrieves and queries orderbook data from the Algorand blockchain. It performs read-only operations with no state modification, financial commitment, or execution of external actions. The 'Fetch' verb and presentation of market data (unified view, spread calculation) confirm pure data retrieval.

From the tool's own definition: "Tool name includes 'get_' and description states 'Fetch the on-chain orderbook' with no side effects. Returns data only (bids, asks, spread) without modifying state or triggering transactions."

## Use case

AI agents call alpha_get_orderbook to retrieve information from Algorand MCP 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)
