Comment on a task

Comment on a task

Adds a comment to a task, optionally assigned to someone, and returns the new comment's id.

On the MCP server, pass entity_type: "task" and the task id as entity_id; the older clickup_create_task_comment is deprecated. On the API, comment_text and notify_all are required. The task's assignees and watchers are always notified; notify_all: true notifies the comment's author as well.

Set up

Use the first option your agent supports.
