New Features 🚀​

Microsoft Teams Integration​

Serenity* Star is now available in Microsoft Teams. Install the app from the Microsoft Marketplace, sign in with your Serenity* Star account, and start using your AI agents directly in chats and channels—without leaving Teams.

Microsoft Teams Integration

Key highlights:

  • Use AI in Teams – Interact with Serenity* Star agents without leaving Microsoft Teams.
  • Multiple conversation contexts – Use agents in personal chats, team channels, and group conversations.
  • Trusted knowledge responses – Get answers grounded in your organization's configured knowledge sources.
  • Secure access – Sign in with enterprise-ready authentication, including SSO support.

To get started, enable the Teams channel on your agent in the Agent Design Studio, then install the app from the Microsoft Marketplace.

Enhancements ✨​

Security – API Key Management​

We’ve strengthened API key security across the entire platform. API keys are no longer exposed in the DOM, and their rendering, copying, and visualization have been redesigned to minimize the risk of accidental exposure. Clipboard interactions are now handled securely, and sensitive operations are processed through controlled server-side actions. These improvements significantly reduce the surface area for data leaks while maintaining a smooth user experience.

MCP Skills – Tool Discovery Support​

MCP Skills that use authentication schemes now support the Get Tools method. This allows you to retrieve and preview the list of tools available on a remote MCP server before configuring your agent. By making external capabilities more transparent, it becomes easier to understand available actions and fine-tune agent behavior accordingly.

Volatile Knowledge within chat history now includes similarity-based retrieval. The system analyzes past messages and dynamically attaches the most relevant fragments. This improves contextual continuity and enhances response accuracy, particularly in longer or more complex conversations.

Agent Design Studio API – Skill Definition Support​

The Agent Design Studio API now allows Skills to be defined programmatically when creating or updating agents. This expands customization possibilities for teams building their own integrations or external clients. Supported API Skills include:

  • Agent Executor
  • Code Execution
  • ImageGenerator
  • Prompt
  • ChartGeneration
  • SpeechGeneration
  • WebSearch

and more. Check out the API Reference for full definitions and configuration settings.

Share Directly from Agent Design Studio​

Agents can now be shared directly from the Agent Design Studio view. This simplifies collaboration and reduces friction when distributing agents internally or externally, providing faster access without additional configuration steps.

Billing and Usage Limits Experience​

We’ve refined the billing and usage limits experience to provide clearer visibility into account activity. Usage and rate limits are now presented more transparently across the cost dashboard and billing overview account settings. These changes make it easier to understand active limits and manage your subscription with confidence.
