Get the full approval preview for a MYOB operation.
AI agents call myob_approval_get 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 approval information for viewing purposes only. It does not create, modify, delete, execute commands, or commit financial transactions. The 'preview' nature further confirms it is inspection-only. Within the server's framework of requiring explicit approval before commit, this tool safely queries pending approval state without side effects.
From the tool's definition Tool name 'myob_approval_get' and description 'Get the full approval preview for a MYOB operation' indicate retrieval of approval data without modification. The verb 'Get' and context of viewing a preview confirm read-only behavior.
