What is Microsoft Copilot Studio?
Copilot Studio is Microsoft's tool for building AI agents without writing much code. You describe what an agent should do, connect it to knowledge such as SharePoint sites, files or websites, give it tools through Power Platform connectors, MCP servers or other agents, and publish it to Microsoft Copilot, Teams, SharePoint, a website or a phone line.
Every agent runs on one of three harnesses, the runtime that decides when to call the model and which tools to use. The GitHub Copilot harness, generally available since 3 August 2026 and the default for new agents, reasons through multi-step work, edits Word, Excel, PowerPoint and PDF files in a sandbox, and supports skills and memory; Microsoft renamed it the Microsoft Copilot harness on 28 October 2026, though Copilot Studio's documentation still uses the old name. The Customer Conversation harness handles voice and chat with customers and hands off to people. The standard harness runs the older rule-based topics and agent flows.
Usage is measured in Copilot Credits, bought in prepaid packs, through an Azure pay-as-you-go meter or as a one-year prepurchase.
How much does Microsoft Copilot Studio cost?
| Plan | Price | What you get |
|---|---|---|
| Credit pack | $200/month | 25,000 Copilot Credits pooled across the tenant; unused credits do not roll over |
| Pay-as-you-go | $0.01 per credit | Billed monthly through an Azure subscription |
Copilot Credits: $200 per month for a pack of 25,000 credits, or $0.01 per credit pay-as-you-go through Azure; one-year prepurchase up to 20% off. Microsoft 365 Copilot users get some internal agent use on the standard harness at no extra charge. Free trial for building and testing, without publishing.
Is Microsoft Copilot Studio worth it?
Every IT team gets the same request: a bot that answers the HR policy questions, or checks an order, or files the expense claim, inside the tools people already use. Building one from scratch means hosting, sign-in, connectors and a support burden nobody budgeted for.
Copilot Studio puts that inside Microsoft 365. An agent built here signs people in with their work accounts, reads the SharePoint sites they can already see, reaches other business systems through Power Platform connectors, and appears in Teams or Microsoft Copilot without an app to install. For a company already paying for Microsoft 365 that integration is worth more than any single feature.
The new GitHub Copilot harness, the default since 3 August 2026, is a real step up. Instead of following topics you draw by hand, it takes a goal, breaks it into steps, calls tools, edits Office files in a sandbox and retries when a step fails. Microsoft's example is an accounts payable agent that matches invoices to purchase orders and routes the exceptions for approval.
The catch: working out the bill takes a spreadsheet. On the standard harness a scripted answer costs 1 credit, a generative answer 2, an agent action 5 and searching your company's Microsoft Graph 10, and a single reply can combine several. A reasoning model adds 10 credits per 1,000 tokens, so Microsoft's own worked example of one follow-up question to a customer support agent costs 141 credits, or 461 if it starts a new conversation. At $200 for 25,000 credits, that is roughly a cent to several dollars a reply.
The new harness changes the rules again. Microsoft says it bills credits for model tokens, tools and the harness itself from the moment you start building, including test chats, and Microsoft 365 Copilot licences do not cover that usage. The "free for licensed users" promise applies only to the standard harness, and you cannot move an agent between harnesses after creation.
Running out is not graceful. When a tenant on prepaid packs reaches 125% of its capacity, its agents stop answering mid-conversation with "This agent is currently unavailable", unless pay-as-you-go overage is switched on. Unused credits expire each month.
Our take: budget Copilot Studio like a phone contract with roaming charges; set per-agent monthly limits and a pay-as-you-go backstop on day one, and the integration with Microsoft 365 is worth the arithmetic.
Where it earns its place
An HR team at a 3,000-person manufacturer on Microsoft 365 Copilot
Answer policy and leave questions in Teams
Build a standard-harness agent grounded in the HR SharePoint site. Classic and generative answers and Graph grounding are not charged when licensed staff use it with their own identity, subject to fair use.
A retailer's customer service manager
Handle 900 website chats a day about returns
Microsoft's example of four scripted and two generative answers per chat comes to 7,200 credits a day, about 216,000 a month: roughly nine $200 packs, or about $2,160 pay-as-you-go.
A finance operations lead
Match supplier invoices to purchase orders and route exceptions
Build on the GitHub Copilot harness, which reads invoices, edits Excel files in its sandbox and calls ERP connectors. Every build, test and run consumes credits, so set a monthly agent limit before the pilot.
Before you commit
- Setup
- A trial lets one person build and test in the test chat but not publish; production needs a tenant credit pack, a pay-as-you-go billing policy linked to Azure, or Microsoft 365 Copilot licences, plus the maker role in the Power Platform admin center.
- Integrations
- Power Platform connectors, MCP servers, connected agents, SharePoint and Microsoft Graph knowledge, Azure Foundry models with your own key, and channels including Teams, Microsoft Copilot, websites and phone numbers.
- Data and privacy
- Microsoft says the GitHub Copilot harness shares technology with GitHub Copilot but customer data is not sent to or processed by the GitHub Copilot service; Copilot Studio's existing privacy, compliance and data residency commitments apply.
- Cost at scale
- Standard harness: 1 credit per scripted answer, 2 per generative answer, 5 per agent action, 10 for Graph grounding, 13 per 100 agent flow actions, 8 per page of content processing, plus 10 per 1,000 tokens for reasoning models; voice runs 10 to 75 credits a minute.
- Limits
- Prepaid tenants are blocked at 125% of capacity unless overage goes to pay-as-you-go; agent flows are blocked separately when an environment has no credits; computer-using agents are never covered by Microsoft 365 Copilot licences.
What’s good
- Agents appear in Teams, Microsoft Copilot and SharePoint with work sign-in
- GitHub Copilot harness plans, retries and edits Office files in a sandbox
- Power Platform connectors, MCP servers and other agents as tools
- Per-agent monthly limits and tenant-wide credit pools
What’s not
- Credit rates vary by feature, harness and model, and stack in one reply
- GitHub Copilot harness bills from the first test chat, licence or not
- Prepaid tenants are blocked at 125% of capacity mid-conversation
- Unused credits expire monthly; agents cannot switch harness
Best for
IT and operations teams in Microsoft 365 organisations that want internal or customer-facing agents without running their own infrastructure.
