Telerik AJAX MCP Server

Updated on Oct 15, 2025

The Telerik AJAX MCP Server lets you interact with AI and reach new levels of developer productivity. The MCP server provides proprietary context to AI-powered IDEs, apps and tools. You can use the Telerik AJAX MCP server for AJAX AI code generation and ask about Telerik UI for ASP.NET AJAX components, features, or general usage. You can successfully prompt more complex questions and tasks, and generate tailored code that includes Telerik UI for ASP.NET AJAX components and API.

Prerequisites

To use the Telerik Telerik AJAX MCP server, you need:

Node.js 18 or a newer version.
A compatible MCP client (IDE, code editor or app) that supports MCP tools. Using the latest version of the MCP client is highly recommended.
A Telerik user account.
An active DevCraft or Telerik UI for ASP.NET AJAX license or a Telerik UI for ASP.NET AJAX trial.
A WebForms application that includes Telerik UI for ASP.NET AJAX.

Check AI Coding Assistant Overview for more recommendations and usage information.

Installation

To install the Telerik MCP server, use the documentation of your AI-powered MCP client. You can enable the MCP server for specific workspaces or globally. The sections below provide installation tips and examples for some popular MCP clients like Visual Studio, VS Code, and Cursor. The generic settings of the Telerik Telerik AJAX MCP server are:

npm package name: @progress/telerik-ajax-mcp
Type: stdio (standard input/output transport)
Command: npx
Arguments: -y
Server name: telerik_ajax_assistant. This name depends on your preferences. The suggestion here matches the MCP tool name in the npm package. See the notes below.
Your Telerik license key as an env parameter

Some MCP clients expect the MCP servers to be listed under a servers JSON key, while others expect mcpServers.

Some MCP clients expect an mcp.json file, while others like Visual Studio 2022 expect an .mcp.json file.

Some MCP clients, including older Visual Studio versions, may not accept a server name that uses hyphens (-) or underscores (_). In such cases, update the MCP client version or use a different server name.

License Key

To use the Telerik MCP Server, your configuration must provide your Telerik licence key as an env parameter in the MCP .json file. There are two options:

Use a TELERIK_LICENSE_PATH argument and point to your Telerik license file location. This approach is recommended, unless you are sharing your VS Code settings across different computers with different operating systems or user names.
Use a TELERIK_LICENSE argument and paste your Telerik license key. Make sure to update the license key when necessary.

Visual Studio

For detailed instructions, refer to Use MCP servers in Visual Studio.

Early Visual Studio 17.14 versions require the Copilot Chat window to be open and active when you open a solution. Otherwise the Telerik MCP server is not used.

To enable the Telerik MCP Server in a specific WebForms app, add a .mcp.json file to the solution folder.

.mcp.json

JSON

{
  "servers": {
    "telerik-ajax-assistant": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@progress/telerik-ajax-mcp@latest" ],
      "env": {
        "TELERIK_LICENSE_PATH": "C:\\Users\\___\\AppData\\Roaming\\Telerik\\telerik-license.txt"
      }
    }
  }
}

To enable global automatic discovery of the Telerik MCP Server in Visual Studio, add the above .mcp.json file to your user directory (%USERPROFILE%), for example, C:\Users\____\.mcp.json.

Once the Telerik MCP server is added, make sure that the telerik_ajax_assistant tool is enabled (checked) in the Copilot Chat window's tool selection dropdown. This dropdown opens when clicking on a wrench icon 🔧 at the bottom of the Copilot Window. The Telerik MCP server may get disabled when starting a new chat, changing threads, or relaunching Visual Studio. This is a known issue with MCP servers in general.

VS Code

For detailed instructions, refer to Use MCP servers in VS Code.

This section applies to VS Code 1.102.1 and newer versions.

Make sure that chat.mcp.enabled is enabled in the VS Code settings.

To enable the Telerik MCP Server in a specific workspace, WebForms app, or globally, add a .vscode folder with an mcp.json file at the root of the workspace, app, or your user folder, respectively.

.vscode/mcp.json

JSON

{
  "servers": {
    "telerik-ajax-assistant": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@progress/telerik-ajax-mcp@latest" ],
      "env": {
        "TELERIK_LICENSE_PATH": "C:\\Users\\___\\AppData\\Roaming\\Telerik\\telerik-license.txt"
      }
    }
  }
}

To use the Telerik MCP server in all workspaces and apps, make sure that chat.mcp.discovery.enabled is enabled in settings.json.

VS Code settings.json

JSON

{
  // ...
  "chat.mcp.discovery.enabled": true,
}

Cursor

For detailed instructions, refer to Model Context Protocol.

To enable the Telerik MCP Server in a specific workspace, WebForms app, or globally, add a .cursor folder with an mcp.json file at the root of the workspace, app, or your user folder, respectively.

.cursor/mcp.json

JSON

{
  "servers": {
    "telerik-ajax-assistant": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@progress/telerik-ajax-mcp@latest" ],
      "env": {
        "TELERIK_LICENSE_PATH": "C:\\Users\\___\\AppData\\Roaming\\Telerik\\telerik-license.txt"
      }
    }
  }
}

Usage

By default, MCP clients do not call MCP tools in a deterministic way. Some MCP clients like VS Code allow you to explicitly reference the desired MCP tool in your prompt.

To use the Telerik MCP Server:

Start your prompt with Telerik to make it more likely for the Telerik MCP server to get called. If you are using VS Code, then start your prompt with:
- # and the MCP server name that you used in mcp.json (for example, #telerik_ajax_assistant)
- # and the name of the Telerik Telerik AJAX MCP tool (#telerik_ajax_assistant)
Confirm that the Telerik MCP server is used. Look for a statement in the output, which is similar to:
- Running telerik_ajax_assistant (in VS Code)
- Calling MCP tool telerik_ajax_assistant (in Cursor)
Grant the Telerik tool permission to run for the current session, workspace, or always.

Sample Prompts

The following list describes how your prompts may look like. Check the Prompt Library for more examples.

"Telerik Generate an AJAX Grid with sorting and paging enabled. Bind the Grid to a Person model and provide dummy data."
"Telerik Generate a ComboBox for AJAX that shows a list of products. Create a Product class and generate sample data."
"Telerik Show me sample code for an AJAX Grid with virtual scrolling for the rows and columns."

Usage Limits

A Telerik Subscription license is recommended in order to use the Telerik Blazor AI Coding Assistant without restrictions. Perpetual license holders and trial users can make a limited number of requests per year.

Connect to Local AI Model

You can use the Telerik Telerik AJAX MCP server with local large language models (LLM). For example, run your local model through Ollama and use a third-party package such as MCP-LLM Bridge to connect the model to the Telerik MCP server. This will allow you to use the Telerik AI Coding Assistant without a cloud-based AI model.
