WebMCP Tools Integration for Syncfusion® React Components

WebMCP enables AI agents to discover and interact with Syncfusion® React components through a standardized tool interface. By enabling WebMCP, AI-powered applications can securely discover component capabilities, read data, perform actions, and automate workflows through a standardized interface.

This section demonstrates how to integrate WebMCP with the Syncfusion® React Spreadsheet component. The same approach can be used with other supported components such as Grid, Scheduler, Chart, and more.

WebMCP Overview

WebMCP allows AI assistants running in the browser to interact directly with Syncfusion® components through natural language prompts.

Instead of relying on DOM inspection or simulating user interactions, AI assistants can interact directly with component APIs through WebMCP tools. This approach provides more reliable and accurate results.

Once connected, an AI assistant can perform tasks such as:

Sort or filter Grid data.
Update Spreadsheet cells.
Create Scheduler events.
Perform component-specific actions through natural language prompts.

WebMCP is currently an experimental browser capability and requires a Chromium-based browser with WebMCP support enabled. Availability and required browser flags may change as the specification evolves.

Prerequisites

Syncfusion® React components
Chromium-based Browser (like Chrome, Edge, or Brave)
Node.js 24+ (LTS recommended).
WebMCP browser extension installed
AI API key configured in the extension

WebMCP setup

Before you can use WebMCP locally, enable the feature flag and install the browser extension:

Enable WebMCP for testing flag via chrome://flags/. Click “Relaunch” to restart Chrome.
Search for “WebMCP - Model Context Tool Inspector” in Chrome Web Store. Click “Add to Chrome”.
Visit Google AI Studio to create or copy an API key. Open the WebMCP extension → paste your API key.

The WebMCP extension is now configured and ready to interact with WebMCP-enabled Syncfusion® components.

Integrating WebMCP tools

Follow these steps to integrate WebMCP support into Syncfusion® React components. The following example uses the Spreadsheet component.

Step 1: Set up the Vite project

Create a React Vite application and integrate the Syncfusion® React Spreadsheet component by following the Getting Started with React Spreadsheet guide. After completing the setup, follow the steps below to enable WebMCP integration.

Step 2: Enable WebMCP support

Import the WebMCP module and inject it into the component to make WebMCP functionality available.

App.jsx
import { SpreadsheetComponent, Spreadsheet, WebMcpSpreadsheet } from '@syncfusion/ej2-react-spreadsheet';

Spreadsheet.Inject(WebMcpSpreadsheet);

function App() {
    return (
        <SpreadsheetComponent
            openUrl='https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/open' 
            saveUrl='https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/save'>
        </SpreadsheetComponent>
    );
}

export default App;

Step 3: Register component tools

Set the enableWebMcp property to true to register the component’s available tools with the WebMCP runtime.

When enableWebMcp is enabled, supported component tools are automatically registered with the WebMCP runtime and become discoverable by authorized WebMCP clients.

For example, a Spreadsheet component may expose tools such as:

getCellData
editCell
addSheet

An AI assistant can discover these tools and invoke them based on user prompts.

App.jsx
import { SpreadsheetComponent, Spreadsheet, WebMcpSpreadsheet } from '@syncfusion/ej2-react-spreadsheet';

Spreadsheet.Inject(WebMcpSpreadsheet);

function App() {
    return (
        <SpreadsheetComponent enableWebMcp={true}
            openUrl='https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/open' 
            saveUrl='https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/save'>
        </SpreadsheetComponent>
    );
}

export default App;

Step 4: Customize tool registration

Use the webMcpSettings property to customize how WebMCP tools are exposed to AI agents. The available settings are listed below.

Property	Description
`name`	Prefix applied to registered tool names. If name: `sales` is specified, a tool such as `getCellData` may be registered as `sales_getCellData`, allowing multiple component instances to coexist without tool name conflicts.
`tools`	List of tool names to expose. Any supported tools not included in this list will not be registered.
`exposeTo`	List of trusted domains that are allowed to interact with the component through WebMCP.

{% tabs %}
{% highlight js tabtitle=”App.jsx” %}

import { SpreadsheetComponent, Spreadsheet, WebMcpSpreadsheet } from ‘@syncfusion/ej2-react-spreadsheet’;

Spreadsheet.Inject(WebMcpSpreadsheet);

function App() {
return (
<SpreadsheetComponent enableWebMcp={true}
webMcpSettings={{
name: ‘sales’,
tools: [‘getCellData’, ‘editCell’, ‘addSheet’],
exposeTo: [‘https://www.syncfusion.com/’]
}}
openUrl=’https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/open’
saveUrl=’https://document.syncfusion.com/web-services/spreadsheet-editor/api/spreadsheet/save’>
</SpreadsheetComponent>
);
}

export default App;

{% endhighlight %}
{% endtabs %}

Use the exposeTo property to restrict WebMCP access to trusted domains. This helps prevent unauthorized WebMCP clients from interacting with your component tools.

Step 5: Monitor and control tool execution

The beforeWebMcpToolExecute event is triggered before a tool is executed. This event allows you to:

Audit tool usage.
Validate incoming requests.
Cancel tool execution when necessary.
Apply custom business rules and security policies.

AI-generated requests should always be validated before executing write operations. Restrict access using exposeTo and perform additional authorization checks within beforeWebMcpToolExecute when modifying application data.
