WHAT IT DOES

What get_nexus_status does on Businys

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

RISK

Why get_nexus_status is rated Low

The tool performs read-only operations: checking status, showing revenue, and flagging thresholds. No data is created, modified, deleted, or executed. However, the sensitivity is elevated (medium rather than low) because it aggregates and exposes financial transaction details and revenue information that could be misused if accessed by an unauthorized agent, though the blast radius is contained to information…

From the tool's definition Tool description states it 'Check[s] sales tax nexus status' and 'Shows revenue and transaction counts per state' — retrieval and querying of existing data with no modification.
