Reply to Instagram comments with Grok Build

Auto-reply tools post the same line under every comment. Grok Build can read each comment and write a reply that answers it. CueEditio lists only the comments you have not replied to yet, so a second run never double-replies.

You

Go through unanswered comments on my last 3 reels. Be witty but kind. Show me before posting.

Example conversation. Post names and counts will be your own.

The CueEditio tools that run

  • list_postsLists recent posts and reels with comment counts so Grok Build can pick the ones with the most waiting.
  • list_commentsPulls comments with unhandled_only, so only comments you have not replied to come back.
  • reply_to_commentPosts each public reply under its comment.

How it works

  1. 1.Connect once

    Add the CueEditio MCP to Grok Build and connect Instagram.

  2. 2.Say which posts and what tone

    "My last 3 reels, short and friendly, answer questions properly."

  3. 3.Review the drafts

    Grok Build shows the replies before posting. Edit any, or say go.

  4. 4.Re-run any time

    Already-answered comments are skipped, so a daily run only touches new ones.

Grok Build runs in your terminal and asks before each tool call. Ask it to show the DM text first.

Limits to know

  • Public replies are capped at 600 per hour per account.
  • Replying needs CueEditio Pro ($6 or ₹459 a month). Listing comments is free.
  • CueEditio replies to top-level comments on your own posts. It cannot comment on other people’s posts.

Give Grok Build two or three of your real replies as examples, or keep a short style note in its instructions. It drafts every reply and shows them to you before posting.

No. The CueEditio MCP can read and reply. It has no tool to hide or delete comments.
