# Postkey > Postkey is the most agentic DM automation tool. It automates Instagram DMs and comments (comment to DM, keyword DMs, follow to unlock, collecting emails, AI replies, an inbox) and schedules posts to 21 networks, so the post and its DMs live in one place. A remote MCP server lets ChatGPT, Claude, Cursor and other AI agents set up automations, answer DMs and schedule posts. A ManyChat alternative that costs less and holds several accounts on one plan.
