Consuming an authenticated MCP server with a declarative agent in Copilot Chat In this post, we'll learn how to create a declarative agent using the Microsoft 365 Agents Toolkit that consumes an Entra-authenticated MCP server.

We’ve built an Entra-authenticated MCP server—now let’s actually use it 👀

Here’s how to connect it to a declarative agent in Copilot Chat using the Microsoft 365 Agents Toolkit and the new MCP support:

Starting today, you can have your MCP servers return interactive components ✨

That's right, you can now put full-blown UI experiences inside your chat - supported in @anthropic.com Claude and @vscode.dev (more clients soon) 🚀

VS Code just announced MCP Apps support! 🔥

Here's one I just made that visualizes git commit history. You can also multi-select commits and have Copilot generate release notes for you!

Check out how to get started with MCP Apps in VS Code here: code.visualstudio.com/blogs/2026/0... #vscode

That is cool! We prototyped something really similar in the past but never made it to the finish line. Happy to chat and make it native within ATK!

Bringing work context to your code in GitHub Copilot - Microsoft for Developers This week we shipped the GitHub Copilot SDK which takes the agent loop from the Copilot CLI and makes it easy to embed in other applications. We’ve been using, improving, and extending Copilot CLI for...

Developing isn't only about writing the code, there's work context and team decisions that come with it.

Work IQ now brings this missing piece directly to GitHub Copilot, and you can leverage it all without leaving your terminal using the Copilot CLI 🔥

I asked GitHub Copilot with Work IQ to compare my PowerToys search spec in SharePoint to the implementation on the GitHub repo and it worked seamlessly.

Being able to pair work context with code in the repo using Copilot is an absolute game changer for development💥💥💥

Welcome - Agent Communication Protocol Get to know the Agent Communication Protocol

Interesting... I was thinking of this ACP share.google/iK2uhF0iBeRB.... A2A is the agent to agent protocol. For agentic coding, it would make a lot of sense that the top agent (Codex, Claude, GitHub, Gemini) were able to talk to other agents (similar to how they can talk to tools today)

14.12.2025 11:22 👍 0 🔁 0 💬 1 📌 0

ACP is now merged inside A2A! And I agree with you, agent-to-agent communication within VS / VS Code and across all coding CLIs would allow for really powerful scenarios! The agent sessions features in VS Code are getting there, but I don't think it uses native A2A.
