What is the difference between Microsoft 365 Copilot Cowork and Microsoft Copilot Studio?

Copilot Cowork is the agent you chat with directly inside Microsoft 365, and it runs as your own identity. Copilot Studio is how you publish a custom agent for other people to use, often under one shared identity. Cowork suits an individual building their own flows; Copilot Studio suits handing a read-only agent to a group. Despite the shared Copilot name, Copilot Cowork, Copilot Studio, and GitHub Copilot are three different products.

Which way to use Flow Studio MCP is best for non-developers?

Microsoft 365 Copilot Cowork. It runs inside Microsoft 365, so there's no editor to install and no config file to edit; you sign in with your work account and ask. An admin deploys the plugin once and it is available to everyone, and it works even if you are new to Power Automate.

Which way to use Flow Studio MCP is best for developers?

An IDE agent: Claude, OpenAI Codex, or GitHub Copilot. You add your own key, so the agent runs as you with full read and write, sees your workspace and repo, and has the largest set of tools. Anyone can set it up themselves with no admin involved.

Can an AI agent change Power Automate flows, or only read them?

It depends on whose identity it runs as. Flow Studio MCP does not add its own permission layer, so the agent can only do what the signed-in identity can already do in Power Automate. Running as your own identity (Cowork, or an IDE agent with your key) inherits your permissions, so it can edit flows you can edit. Running under one shared identity (Copilot Studio with the maker's key) is best kept read-only, because a shared identity with write access makes changes no one can trace to a person.

How do I give a team shared access to Power Automate through an AI agent?

Use Microsoft Copilot Studio. Someone with a Copilot Studio license publishes one agent that the whole group can use. With the maker's shared key, one service principal account serves everyone, which is convenient but should stay read-only since there is no per-user attribution. With each end-user's own key, writes are allowed and attributed to the right person.

Which AI Agent Should You Use With Flow Studio MCP for Power Automate?

Q: Which AI agent should I use to build Power Automate flows?

It depends on how you work. If you build flows but don't work in a code editor, use Microsoft 365 Copilot Cowork. If you're a developer, use an IDE agent such as Claude, OpenAI Codex, or GitHub Copilot. If you want to give a group of people one shared agent, use Microsoft Copilot Studio and keep it read-only. All three connect to the same Flow Studio MCP server; what changes is whose identity the agent runs as, which decides whether it can change flows or only read them.

Short answer: If you build flows but don’t work in a code editor, use Microsoft 365 Copilot Cowork. If you’re a developer, use an IDE agent — Claude, Codex, or GitHub Copilot. If you want to give a group of people one shared agent, use Microsoft Copilot Studio and keep it read-only. All three connect to the same Flow Studio MCP server. What changes is whose identity the agent runs as, and that decides whether it can change your flows or only read them.

The three options at a glance

Flow Studio MCP is one server. You reach it through a host — the AI agent you actually talk to. There are three hosts, and they share a confusing amount of branding, so to be clear:

Microsoft 365 Copilot Cowork — Microsoft’s agent inside Microsoft 365. You chat with it in plain language; an admin switches the plugin on once for the whole organization.
IDE agents — coding assistants that run in a code editor: Claude, OpenAI Codex, GitHub Copilot. You add your own key and they work alongside your files and repo.
Microsoft Copilot Studio — Microsoft’s tool for publishing a custom agent that other people can use.

These are three different products that happen to share the “Copilot” name. Copilot Cowork, Copilot Studio, and GitHub Copilot are not the same thing.

	Microsoft 365 Copilot Cowork	IDE agents Claude · Codex · GitHub Copilot	Microsoft Copilot Studio
Who it’s for	Flowmakers and business users, no coding	Developers	An org giving a group one shared agent
How you sign in	SSO — your Microsoft 365 account	Your own key	A key set when the agent is published
Whose identity it runs as	You — your own	You — your own key	The maker’s shared key (one identity for everyone), or each end-user’s own key
Can it change flows?	Inherits your Power Automate permissions — writes if you can	Inherits your permissions — full read and write	Shared key: keep it read-only. End-user key: read and write, attributed to that user
Who sets it up	A Microsoft 365 admin, once for everyone	Any individual, self-serve	Someone with a Copilot Studio license
Where you work	Inside Microsoft 365 Copilot Cowork	VS Code and other editors, with your workspace and repo in context	Wherever the published agent runs

If you’re a developer working in an IDE

Use an IDE agent — Claude, Codex, or GitHub Copilot. You add your own key, so the agent runs as you with full read and write. It also sees your workspace and repo, has the largest set of tools, and is the fastest way to build and fix flows if you already live in a code editor. Anyone can set this up themselves; no admin needed.

Setup: Getting Started with Flow Studio MCP, or the per-agent guides for Claude and GitHub Copilot.

If you build flows but don’t live in a code editor

Use Microsoft 365 Copilot Cowork. It runs inside Microsoft 365, so there’s no editor to install and no config file to edit — you sign in with your work account and ask. Your admin deploys the plugin once and it’s available to everyone, so each person just switches it on. It runs as your own identity, which means it can build and fix flows up to whatever your Power Automate permissions already allow. This is the path that needs no developer tooling, and it works even if you’re new to Power Automate.

Setup: Set Up Flow Studio MCP in Microsoft 365 Copilot Cowork.

If you’re rolling this out to a team

Use Microsoft Copilot Studio. Someone with a Copilot Studio license publishes one agent, and a whole group can use it. There are two ways to wire the key:

Maker’s shared key — one service principal account and one published agent serve the whole group. Convenient to run, but everyone shares one identity, so there’s no per-user attribution. Keep this one read-only: debug, triage, and inventory, not writing changes.
End-user’s own key — each person uses their own key, so writes are allowed and attributed to the right user. Use this when the group needs to make changes, not just look.

Setup: Copilot Studio + Power Automate.

Copilot Cowork vs Copilot Studio — what’s the difference?

Copilot Cowork is the agent you chat with directly inside Microsoft 365; it runs as you. Copilot Studio is how you publish a custom agent for other people to use, often under one shared identity. Cowork is the better fit for an individual building their own flows. Copilot Studio is the better fit for handing a read-only agent to a group.

Write or read-only? It comes down to whose identity it runs as

This is the real decision. Flow Studio MCP doesn’t add its own permission layer — the agent can only do what the signed-in identity can already do in Power Automate, through the connections granted at setup.

Your own identity (Cowork, or an IDE agent with your key) — the agent inherits your permissions. If you can edit a flow, so can it. Every action is attributed to you.
One shared identity (Copilot Studio with the maker’s key) — everyone in the group acts as the same account. That’s why we recommend keeping it read-only: a shared identity with write access means changes no one can trace back to a person.

Does this bypass your governance? No.

Whichever host you pick, the agent works within the identity it runs as — the same roles, the same Data Loss Prevention policies, the same connection grants. Everything it does lands in Power Automate run history and your Microsoft Purview audit log, exactly as if the person had done it by hand. There’s no side channel.
