How it fits together
Plugins, apps and MCP, in one picture.
A plugin is what you install. Inside it are apps that connect ChatGPT to a service, skills that teach it a workflow, and templates to start from. Every app runs on an MCP server, and you can connect your own servers directly in developer mode.
