Quickstart
Get started with Teams SDK quickly using the Teams CLI.
Set up a new project
Prerequisites
- Python v3.12 or higher. Install or upgrade from python.org/downloads.
- UV v0.8.11 or higher. Install or upgrade from https://docs.astral.sh/uv/getting-started/installation/
UV is a fast Python package installer and resolver. While you can use other package managers like pip, UV provides better performance and dependency resolution for Teams SDK projects.
Instructions
Use the Teams CLI
Use your terminal to run the Teams CLI using npx:
npx @microsoft/teams.cli --version
The Teams CLI is a command-line tool that helps you create and manage Teams applications. It provides a set of commands to simplify the development process.
Using npx allows you to run the Teams CLI without installing it globally. You can verify it works by running the version command above.
Creating Your First Agent
Let's begin by creating a simple echo agent that responds to messages. Run:
npx @microsoft/teams.cli@latest new python quote-agent --template echo
This command:
- Creates a new directory called
quote-agent. - Bootstraps the echo agent template files into it under
quote-agent/src. - Creates your agent's manifest files, including a
manifest.jsonfile and placeholder icons in thequote-agent/appPackagedirectory. The Teams app manifest is required for sideloading the app into Teams.
The
echotemplate creates a basic agent that repeats back any message it receives - perfect for learning the fundamentals.
Running your agent
Navigate to your new agent's directory:
cd quote-agent
Start the development server:
uv run src\main.py
In the console, you should see a similar output:
[INFO] @teams/app Successfully initialized all plugins
[WARNING] @teams/app.DevToolsPlugin ⚠️ Devtools is not secure and should not be used in production environments ⚠️
[INFO] @teams/app.HttpPlugin Starting HTTP server on port 3978
INFO: Started server process [6436]
INFO: Waiting for application startup.
[INFO] @teams/app.DevToolsPlugin available at http://localhost:3979/devtools
[INFO] @teams/app.HttpPlugin listening on port 3978 🚀
[INFO] @teams/app Teams app started successfully
[INFO] @teams/app.DevToolsPlugin listening on port 3979 🚀
INFO: Application startup complete..
INFO: Uvicorn running on http://0.0.0.0:3979 (Press CTRL+C to quit)
When the application starts, you'll see:
- An HTTP server starting up (on port
3978). This is the main server which handles incoming requests and serves the agent application. - A devtools server starting up (on port
3979). This is a developer server that provides a web interface for debugging and testing your agent quickly, without having to deploy it to Teams.
The DevTools server runs on a separate port to avoid conflicts with your main application server. This allows you to test your agent locally while keeping the main server available for Teams integration.
Now, navigate to the devtools server by opening your browser and navigating to http://localhost:3979/devtools. You should see a simple interface where you can interact with your agent. Try sending it a message!

Next steps
After creating and running your first agent, read about the code basics to better understand its components and structure.
