Give your agent full access to your Plain support threads and customers during calls.

Connect Plain MCP and your agent can read and act inside your Plain workspace while it talks with callers. It can look up customers and threads, add labels, change thread priority, assign conversations to the right person, and add reply suggestions for your team to review. It can also work with help-center content and workspace settings when a call needs it. Plain MCP gives your agent around 80 actions, so it can handle the support tasks your team does by hand.
