[!IMPORTANT] Breaking Change Notice: As of version 0.6.0, this repository has transitioned to a multi-module structure.

• For new versions (v0.6.0+): You must import specific modules (e.g., go get github.com/googleapis/mcp-toolbox-sdk-go/core).
• For older versions (v0.5.1 and below): The repository remains a single-module library (go get github.com/googleapis/mcp-toolbox-sdk-go).
• Please update your imports and go.mod accordingly when upgrading.

This repository contains the Go SDKs for MCP Toolbox. These SDKs allow you to load and use tools defined in your MCP Toolbox server as standard Go structs within your Agentic applications.

For comprehensive guides and advanced configuration, visit the Main Documentation Site.

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 MCP Toolbox-managed tools directly within your Go applications or AI orchestration frameworks.

Available Packages

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