Claude + Postkey
Instagram DM automation with Claude
Add Postkey to Claude once, then ask in plain words. Claude builds the comment-to-DM automation, drafts the replies and schedules the post.
The short answer
Yes. Postkey is the most agentic DM automation tool, and Claude can run it for you. Connect Postkey's MCP server (https://postkey.pro/mcp) to Claude, sign in, and choose what it may do. It can then create comment-to-DM automations, answer your inbox and schedule posts, using up to 45 Postkey tools, and anything that reaches real people waits for your yes.
What you can ask Claude
Ask in your own words. A few things people ask on the first day:
- Set up an automation: anyone who comments GUIDE under my next reel gets my guide link by DM.
- Only send the link to people who follow me, and ask everyone else to follow first.
- Which DMs are still unread? Draft replies to the shipping questions.
- Write a caption for Friday's drop, use the video from my library, and schedule it for 9am on Instagram and TikTok.
- How did my posts do this month, and which automation got the most link taps?
- Find @afan in my contacts and tag them VIP.

Why Postkey is the most agentic DM automation tool
Postkey was built for AI agents from the start, not given an API afterwards. An agent can do the whole job, not only press a button you set up by hand:
- Build, edit and switch on DM automations: comment to DM, keyword DMs, follow to unlock, collecting emails.
- Read the inbox, draft replies and send them once you say yes.
- Write, schedule and publish posts, and set the DM keyword each post's comments reply to.
- Find and tag contacts, and report how posts and automations did.
- Up to 45 tools in one MCP server, with OAuth sign-in or an agent key, and a skill file that teaches the agent the rules.
- Approvals, limits and protection from instructions hidden in DMs built in, so you can let an agent run it.
Why use Claude for your DMs
Claude is good at the parts people put off: writing the DM, picking the keyword, answering a full inbox. Postkey gives it the tools to do them on your real Instagram account, with your yes before anything is sent.
Postkey is DM automation and a post scheduler in one, so the same conversation can write the post, schedule it to 10 networks and set the keyword its comments reply to.
You stay in charge
- It acts as you, on the one account you picked, inside your plan and its limits.
- Publishing a post, sending a reply and switching on an automation wait for your yes by default.
- Each connection has limits: up to 60 requests a minute and 200 changes a day by default.
- Text from DMs and comments reaches the assistant marked as written by someone else, and it is told never to follow it.
- Billing, your team, connected accounts and deleting contacts stay with you. An assistant cannot touch them.
- End a connection at any time and its next request is refused.
Questions
Not by default. Sending a reply, publishing a post and switching on an automation wait in Postkey for your yes. An owner or admin can change that for one connection.
No. You sign in to Instagram on Meta's own page when you connect it to Postkey, and the assistant only gets the access you choose in Postkey.
Yes. Claude's Free plan allows one custom connector, and paid plans allow more. Add Postkey once and it is there on the web, the desktop app, the phone app and Claude Code.
Not yet. Until it is, add it as a custom connector with your Postkey address. It takes about a minute.
We found no official ManyChat MCP server or Claude connector (searched October 20, 2026). Community-built servers wrap ManyChat's API, which needs a paid ManyChat plan.
