Troubleshooting
This article provides solutions to common issues you may encounter when working with the Kendo UI for Angular AI Tools.
AI Coding Assistant Stopped Working
Starting in February 2026, we restructured the Kendo UI for Angular AI Tools to better serve different user needs by deprecating the AI Coding Assistant. The Kendo UI for Angular MCP server now provides a single workflow centered around the Agentic UI Generator tool and its specialized MCP assistants.
As part of this restructuring, license requirements have also changed.
- All active Telerik subscription models—Provide access to the Agentic UI Generator.
- Trial licenses—Provide access during the active trial period.
- Perpetual licenses—Do not grant access to the AI tools. You must have an active Subscription or trial license to use the Kendo UI for Angular MCP server.
For detailed information about license requirements, see License Requirements.
I Started a Trial License but Cannot Activate the MCP Server
When you activate a trial license, you must download and install the updated license key to enable access to the AI Tools. To resolve this issue:
- Download your trial license key from your Telerik account.
- Install or update the license key in your development environment.
- Restart your IDE to ensure the changes take effect.
- Start the MCP server.
The MCP server validates your license during initialization. Without a properly installed trial license key, the server cannot authenticate your access to the AI Tools.
The MCP Server Assistants Are Not Recognized by VS Code
If the Kendo UI for Angular MCP server assistants are not available or recognized by GitHub Copilot in VS Code, you may need to manually enable them:
- In the bottom right of the Copilot chat window, click Configure Tools.
- In the popup, check the kendo-angular-mcp-server from the list to enable it.
The MCP Server Start Button Is Missing
If the MCP server start button is not visible and displays an error message instead, this typically indicates a licensing or configuration issue.
To resolve this:
- Verify your license—Ensure you have an active Subscription or trial license. Perpetual licenses do not grant access to the AI Tools.
- Verify the MCP server configuration—Ensure the MCP server is properly configured in your VS Code settings as described in the Installation guide.
- Restart your IDE—Close and reopen VS Code to ensure all changes take effect.
If the issue persists after following these steps, check your license status in your Telerik account to confirm it's active and includes access to the AI Tools.
