# reply_to_comment

Source: https://modulify.ai/docs/mcp/comments/reply-to-comment

Adds a reply to an existing comment thread.

- Title: Reply to a comment
- Scope: `comments:write`
- Access: Makes changes

This is how you answer a reviewer, for example to say a change has been made. The reply inherits the pin position of the thread it belongs to, so it needs no coordinates. A reply to a deleted comment is refused.

As with `create_comment`, a mention left from here never emails the person. It only resolves to a real teammate in the token form `@Name{userId}`, and a plain `@name` is just text.

Anyone holding the site's shared link can read the reply while viewers can comment. The text is at most 1,000 characters, and text that is empty or longer than that is refused. See [Comments](https://modulify.ai/docs/editor/comments#read-and-reply).
