Show MYOB OAuth authentication, token, and selected business status.
AI agents call myob_auth_status to retrieve information from MYOB Codex MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and displays current authentication and business context information. It performs no writes, mutations, deletions, code execution, or financial operations. The data returned is read-only status information. While it may reveal sensitive details (tokens, auth state), that makes it a read operation with potential information disclosure risk, not a mutation or destructive action.
From the tool's definition Tool name 'myob_auth_status' and description 'Show MYOB OAuth authentication, token, and selected business status' indicate a query/retrieval operation with no side effects. The verb 'Show' denotes information retrieval only.
