# MCP Toolbox SDKs for Javascript

[![License: Apache 2.0](https://img.shields.io/badge/License-Apache%202.0-blue.svg)](https://opensource.org/licenses/Apache-2.0)

The @toolbox-sdk/core package provides a Javascript interface to the [MCP Toolbox](https://github.com/googleapis/mcp-toolbox) service, enabling you to load and invoke tools from your own applications. It is framework-agnostic and designed to seamlessly integrate with popular orchestration frameworks like Langchain and Genkit.

For detailed guides, authentication examples, and advanced configuration, visit the [JS SDK Core Guide](https://mcp-toolbox.dev/documentation/connect-to/toolbox-sdks/javascript-sdk/core/).

# Supported Environments

This SDK is a standard Node.js package built with TypeScript, ensuring broad
compatibility with the modern JavaScript ecosystem.

- Node.js: Actively supported on Node.js v18.x and higher. The package is
  compatible with both modern ES Modules (import) and legacy CommonJS
  (require).
- TypeScript: The SDK is written in TypeScript and ships with its own type
  declarations, providing a first-class development experience with
  autocompletion and type-checking out of the box.
- JavaScript: Fully supports modern JavaScript in Node.js environments.

## Installation

```bash
npm install @toolbox-sdk/core
```

## Quickstart

Here's a minimal example to get you started. Ensure your Toolbox service is running and accessible.

```javascript

import { ToolboxClient } from '@toolbox-sdk/core';  
const client = new ToolboxClient(URL);  

async function quickstart() {  
  try {  
      const tools = await client.loadToolset();  
      // Use tools  
  } catch (error) {  
      console.error("unable to load toolset:", error.message);  
  }  
}  
quickstart();  
```

> [!NOTE]
> This guide uses modern ES Module (`import`) syntax. If your project uses
> CommonJS, you can import the library using require: `const { ToolboxClient }
> = require('@toolbox-sdk/core')`;.
