The new Teams AI Library is now empowering developers to create intelligent agents for Microsoft Teams with unprecedented speed and efficiency. With streamlined tools, advanced agent orchestration, and rich user experience features, the updated Teams AI Library aims to make coding enjoyable and productive while unlocking the next generation of collaborative AI inside Teams.

Microsoft Unveils Upgraded Teams AI Library for Lightning

Microsoft has introduced a major update to its Teams AI Library, a toolkit that enables developers to build, deploy, and manage AI-powered agents within Microsoft Teams.With more than 100,000 monthly downloads, the Teams AI Library is already a trusted companion for the developer community. The latest release promises to help developers build powerful Teams agents up to 90% faster, thanks to extensive enhancements inspired by real user feedback.

A Developer-Centric Approach: Fast, Streamlined, and Fun

Responding directly to feedback, Microsoft has engineered the new Teams AI Library to prioritize a seamless, developer-first experience. The updated SDK is not just easier to use—it injects joy back into the coding journey by eliminating the complexity that often slows down innovation. With a single integrated SDK, developers can now avoid switching between separate tool kits like Botbuilder, Microsoft Graph, and Adaptive Cards. Instead, they can focus on implementing logic unique to their bots, reducing boilerplate coding by up to 90%.

Demo of Simplicity in Action

import { App } from '@microsoft/teams.apps';

const app = new App();

app.on('message', async ({ api, isSignedIn, send, signin }) => {
  if (!isSignedIn) {
    await signin();
  }
  const me = await api.user.me.get();
  await sendHello, ${me.displayName}!);
});

This minimal code snippet demonstrates how quickly developers can have a functional Teams agent responding to users—without the overhead of manual integrations.

Unified Tools and Reduced Coding Overhead

The new Teams AI Library consolidates all the tools needed for intelligent agent development into a single SDK. Developers can now build sophisticated, collaborative bots in a fraction of the time, with updates including:

  • Unified SDK for Teams: No more juggling multiple frameworks—everything needed is built-in.

  • Drastically Less Boilerplate: The library trims repetitive code by up to 90%, so developers can ship production-ready agents faster than ever.

  • Adaptive Cards Support: Innovative, visually rich adaptive cards are now simpler to generate and integrate, enabling agents to interact with users via tables, charts, buttons, and inputs directly within Teams chat. Resources for building adaptive cards are readily available for developers wanting to design beautiful, interactive responses for end users.

Advanced Intelligence: Introducing Model Context Protocol (MCP)

A significant highlight is support for Model Context Protocol (MCP), a next-generation agent orchestration standard. MCP allows agents built using the Teams AI Library to seamlessly share memory and tools across multiple services, supporting complex, multi-agent workflows. Whether integrating external AI services or coordinating several agents, MCP enables richer, more productive workflows within Teams.

Sample Integration with MCP

const prompt = new ChatPrompt(
  {
    instructions: 'You are a helpful assistant. You MUST use tool calls to do all your work.',
    model: new OpenAIChatModel({
      model: 'gpt-4o-mini',
      apiKey: process.env.OPENAI_API_KEY,
    }),
  },
  [new McpClientPlugin()]
)
  .usePlugin('mcpClient', { url: 'http://localhost:3000/mcp' })
  .usePlugin('mcpClient', {
    url: 'https://pokemonmcp.azurewebsites.net/runtime/webhooks/mcp/sse',
    params: {
      headers: {
        'x-functions-key': process.env.AZURE_FUNCTION_KEY!,
      },
    },
  });

Developers can follow comprehensive guides to quickly set up MCP server integration, further elevating agent capabilities.

Real-World Impact: Partner Success and Community Engagement

Microsoft partners are already reaping the rewards of these improvements. Companies like Goodcall report a much faster setup and development pace, helping technical teams create smart solutions with minimal friction. Developers new to Teams and seasoned experts alike can jump in with confidence using the updated documentation and vibrant developer community forums.

Get Started: Resources and Community

Whether you’re building your first Teams agent or scaling enterprise solutions, Microsoft offers a robust ecosystem to support your journey:

  • Quick Start Guide: Launch your first agent in minutes using Visual Studio Code and the step-by-step quick start documentation.

  • Join the Developer Community: Participate in forums, share feedback, and shape the future of Teams AI by connecting with other developers and reporting issues as they arise.

  • Explore Adaptive Cards: Access tools to rapidly build visually immersive adaptive cards and enhance user engagement.

The New Era for Teams AI: What Will You Create?

With these sweeping enhancements, the Teams AI Library invites innovation at every level. By simplifying the development process, embracing advanced agent orchestration, and prioritizing real-world usability, Microsoft is setting the stage for unprecedented creativity inside Teams.
