Configuration Examples

Visual Studio

Refer to Use MCP servers in Visual Studio.

SOLUTIONDIR/.mcp.json

{
  "servers": {
    "telerik-winforms-assistant": {
      "type": "stdio",
      "command": "dnx",
      "args": ["Telerik.WinForms.MCP", "--yes"]
    }
  },
  "inputs": []
}

• Avoid using hyphens "-" or underscores "_" in the MCP server name in the MCP .json file, due to potential compatibility issues with some MCP clients such as Visual Studio.
• Once the Telerik MCP server is added, make sure that the telerikWinFormsAssistant tool is enabled (checked) in the Copilot Chat window's tool selection dropdown in Visual Studio.

## Usage

To use the Telerik UI for WinForms MCP server:

1. Start your prompt with one of the following:
    * `#telerik-winforms-assistant`
    * `telerik`
    * `/telerik`
    * `@telerik`
    * `telerikwinforms`
    * `/telerikwinforms`
    * `@telerikwinforms`

   Or if you are using VSCode you can type `#telerik-winforms-assistant` to make sure the Copilot chat will call the Telerik UI for WinForms MCP server.

1. Confirm that the Telerik UI for WinForms MCP server is used, because this doesn't happen deterministically. Look for a statement in the output, which is similar to:
    * `Running telerik-winforms-assistant` (in Visual Studio)

    If the Telerik UI for WinForms MCP server is not used even though it's installed and enabled, then try rephrasing your prompt and use another trigger syntax from the list in step 1.
1. Grant the Telerik UI for WinForms MCP server a permission to run for this session, workspace, or always.
1. If you want to prompt for information or code that are not related to your previous prompts, it is a good practice to start a new session in a new chat window, so that the context is not polluted by irrelevant old information.

To increase the probability of the Telerik UI for WinForms MCP Server being used, or to call it without the need to mention "telerik" explicitly, add custom idea instructions to your AI-powered tool.
