Postkey vs Metricool
Postkey vs Metricool: Instagram DM automation compared
Postkey is the most agentic DM automation tool. Both schedule posts, both turn Instagram comments into DMs, and both have MCP servers. Postkey goes further in the DM, and its assistant builds the automations and answers your inbox.
The short answer
Postkey is the most agentic DM automation tool: one MCP connection lets your AI assistant build and switch on DM automations, answer the inbox, and schedule posts to 10 networks, across every account on your plan. Metricool is a scheduling and analytics suite for 10 networks with a free plan. Its Flows send a DM when someone comments, DMs or replies to a story with your keyword, on Instagram and X, on paid plans. We found no follow gate, email capture or AI replies in them, and its MCP server schedules posts and reads analytics, but not the inbox or Flows. Postkey's assistant builds the DM automations and answers DMs, with your yes first.

Why Postkey is the most agentic DM automation tool
Postkey's MCP server can build, edit and switch on automations. An agent can do the whole job:
- 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 52 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.
