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 January 2026, we restructured the Kendo UI for Angular AI Tools to better serve different user needs. Both the AI Coding Assistant and the Agentic UI Generator are now delivered through a single Kendo UI for Angular MCP server. The AI Coding Assistant is a streamlined version of the Agentic UI Generator, providing access to Component and Icon tools with a component-focused orchestrator.
As part of this restructuring, license requirements have also changed. Depending on your subscription license type, you may have access to different tool capabilities:
- DevCraft Complete or Ultimate Subscription—Provides full access to the Agentic UI Generator, including all Component, Layout, Styling, and Icon tools with comprehensive orchestration capabilities.
- DevCraft UI, Kendo UI or Kendo UI for Angular Subscription—Provides access to the AI Coding Assistant with Component and Icon tools.
- Perpetual licenses—Do not grant access to any of 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 and tool capabilities, 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 Tools Are Not Recognized by VS Code
If the Kendo UI for Angular MCP server tools 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.
