How to add an MCP server to Microsoft Copilot Studio

Name: Microsoft Copilot Studio
Author: Microsoft

In Microsoft Copilot Studio, MCP servers can be added as a custom connector; its docs show the OpenAPI connector definition below. Where to add them: Agent Tools page > Add a tool > New tool > Model Context Protocol (MCP onboarding wizard), or a custom connector created in Power Apps from an OpenAPI schema file. Its docs list support for Streamable HTTP and say SSE is not supported. They do not state stdio. It handles OAuth sign-in for remote servers.

Which server?

Pick a server from the verified directory of official MCP servers. Each one lists its transport, auth and the setup snippets its vendor publishes, so you can match it to what Microsoft Copilot Studio supports.

What the Microsoft Copilot Studio docs say it supports. Not stated means the docs do not say either way.
