Microsoft's Big June 2026 Launch: Service Agent and MCP Go GA in Microsoft 365 Copilot

Licensing requirements. Service Agent itself is accessed through Microsoft 365 Copilot Chat, which is available at no additional cost to users with eligible Microsoft 365 or Office 365 subscriptions . However, the underlying Dynamics 365 Customer Service data integration requires a Dynamics 365 Customer Service license. For organizations that need premium Copilot features, a Microsoft 365 Copilot add-on license is also required. Broader Copilot ecosystem licensing — including Copilot Credits for usage-based billing — is detailed in Microsoft's Copilot Studio Licensing Guide .

Model Context Protocol (MCP) — General Availability

Microsoft announced on June 22, 2026, that Model Context Protocol (MCP) integration is now generally available in Microsoft Copilot Studio . MCP is an open standard that connects AI agents to various data systems, knowledge servers, and APIs, enhancing the relevance and accuracy of agent responses . With MCP GA, makers can connect Copilot Studio agents to enterprise knowledge systems with growing connector support, better tool rendering, and improved scalability . The protocol allows agents to access dynamic, real-time content — files, database records, API responses — from directly within Copilot Studio, without custom integration code .

Broader June 2026 Product Milestones

June 2026 was a major release month across Microsoft's agent platform. Key milestones include:

• Copilot Cowork GA (June 16, 2026) — Microsoft 365 Copilot Cowork reached general availability worldwide (Tier 1 languages), enabling long-running delegated multi-step tasks with enterprise approvals, plugin extensibility, model choice, and cost controls. It requires a Microsoft 365 Copilot license plus usage-based billing via Copilot Credits .
• Microsoft Scout unveiled — At Build 2026, Microsoft introduced Scout, described as its first "autopilot" agent for proactive, autonomous task execution .
• Work IQ API GA (June 16, 2026) — Reached general availability, allowing customers to build agents and apps that use Microsoft 365 data, context, and tools securely at scale .
• Copilot SDK GA — The Copilot SDK reached general availability alongside MCP, enabling organizations to securely connect internal services to the Copilot ecosystem .
• Model choice in Copilot Chat — Users can now select Anthropic's Claude as a model within Copilot Chat .
• Agent 365 (security/governance) — GA (May 1, 2026) — Microsoft Agent 365 went GA at $15/user/month as a unified enterprise control plane for agent governance, with eligibility requirements taking effect June 1, 2026 (requires Microsoft 365 E5, F5 Defender + Purview, or Business Premium) .
• Microsoft 365 E7 SKU — GA — A new enterprise licensing tier was introduced .
• Copilot pricing update — As of July 1, 2026, the Microsoft 365 Copilot add-on price dropped from $21/user/month to $18/user/month (with a limited-time discount offer running July–September 2026) .

Key takeaway: Service Agent reached GA in June 2026 after its March 31 public preview, MCP went GA on June 22 in Copilot Studio, and the month was anchored by the Copilot Cowork GA on June 16, the unveiling of Scout at Build, and the Copilot SDK GA — all part of a sweeping platform-wide push toward agentic, multi-model, and usage-based AI experiences.
