List jobs.
AI agents call myob_job_list 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.
The tool lists jobs in MYOB, which is a read-only operation that retrieves data without side effects. No creation, modification, deletion, or execution occurs. The server's stated design provides 'read-only tools by default', and this tool fits that pattern. Severity is low because listing jobs has minimal blast radius if misused—an agent could over-retrieve data but cannot modify accounts or financial records.
From the tool's definition Tool name 'myob_job_list' and description 'List jobs' indicate a query/retrieval operation with no modification capability.
