Overview

Open source MCP Toolbox for Databases is an MCP server for databases. It enables you to develop tools easier, faster, and more securely by handling the complexities such as connection pooling, authentication, and more. Toolbox sits between your application's orchestration framework and your database, providing a control plane used to modify, distribute, or invoke tools. It simplifies the management of your tools by providing a centralized location to store and update tools, allowing you to share tools between agents and applications and update those tools without redeploying your application. This project is in beta and may see breaking changes until the first stable release (v1.0). The solution originated as Gen AI Toolbox for Databases and was renamed to align with MCP compatibility. Toolbox emphasizes faster development, better performance, enhanced security, and observability with OpenTelemetry. It supports dynamic reloading by default, and provides multiple installation and running options (binary, container image, Homebrew, compiling from source). Comprehensive docs and SDK examples cover multi-language clients and integration with Gemini CLI Extensions.
