WHAT IT DOES

What UpdateOneWorkflowVersion does on Twenty MCP Server

RISK

Why UpdateOneWorkflowVersion is rated Medium

This tool modifies workflow version data in the Twenty CRM system reversibly. It is a Write operation (creates or modifies data reversibly) rather than Destructive since updates can typically be undone or modified further. The severity is medium because workflow version changes could affect business processes, but the impact is scoped to a single workflow version record and remains reversible.

From the tool's definition Tool name 'UpdateOneWorkflowVersion' explicitly uses 'Update' verb, indicating modification of existing data. Description confirms 'Update One workflowVersion' action.
