# Update Task

POST https://mcp.openantares.com/v1/tools/update_task
Content-Type: application/json

Edit an existing task by its board identifier (for example 'ACME-5', or just 5; the prefix is whatever this vault uses) or by taskId from list_tasks. Fields: status, named owner, t-shirt estimate, priority, labels, checklist, due date, milestone, title and description. Pass null to clear a clearable field (estimate, dueDate, milestoneId, assigneeName, description). Requires a manager API key.
