Go

Overview

The MCP Toolbox service provides a centralized way to manage and expose tools (like API connectors, database query tools, etc.) for use by GenAI applications.

The Go SDK act as clients for that service. They handle the communication needed to:

• Fetch tool definitions from your running Toolbox instance.
• Provide convenient Go structs representing those tools.
• Invoke the tools (calling the underlying APIs/services configured in Toolbox).
• Handle authentication and parameter binding as needed.

By using the SDK, you can easily leverage your Toolbox-managed tools directly within your Go applications or AI orchestration frameworks.

Which Package Should I Use?

Choosing the right package depends on how you are building your application:

• core: This is a framework-agnostic way to connect tools to popular frameworks like Google GenAI, LangChain, etc.

• tbadk: This package provides a way to connect tools to ADK Go.

• tbgenkit: This package provides functionality to convert the Tool fetched using the core package into a Genkit Go compatible tool.

Available Packages

This repository hosts the following Go packages. See the package-specific README for detailed installation and usage instructions:

Getting Started

To get started using Toolbox tools with an application, follow these general steps:

1. Set up and Run the Toolbox Service:

   Before using the SDKs, you need the MCP Toolbox server running. Follow the instructions here: Toolbox Getting Started Guide

2. Install the Appropriate SDK:

   Choose the package based on your needs (see “Which Package Should I Use?” above) Use this command to install the SDK module

   # For the core, framework-agnostic SDK
