What q402_balance does on Q402 Mcp
AI agents call q402_balance to retrieve information from Q402 Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why q402_balance is rated Low
This tool queries and returns information about configured API credentials. It has no side effects, does not move funds, execute code, or alter data. While API key exposure is a security concern in misuse, the tool itself is a pure read operation. Severity is low because exposure of credentials is the risk of credential handling generally, not this tool's inherent capability.
From the tool's definition Tool performs verification and reporting of API keys—examining configuration state without modifying or executing external operations. The verb 'Verify' and 'report' indicate read-only introspection.
