What is Customer.io MCP?

The Customer.io MCP server is a Model Context Protocol server that connects Customer.io to AI agents and assistants as a set of tools. With it connected, an agent can work with Customer.io (customer engagement — messaging campaigns, journeys, segments, and broadcasts) directly — instead of you copying data in and out by hand.

It is a remote MCP server that uses OAuth, so you point your client at the server URL, authorize once, and the Customer.io tools become available to the model.
