Mcp Toolbox

This is an open source Model Context Protocol server that connects AI agents, IDEs and applications to enterprise databases. It was originally named Gen AI Toolbox for Databases, because its development predated MCP, and it was renamed when MCP support was added. The GitHub repository under the googleapis organization has likewise been renamed to match. It serves two purposes. As a ready to use MCP server, it lets clients such as Gemini CLI, Claude Code and Codex reach databases through prebuilt generic tools, with operations like listing tables and executing SQL, so a developer can explore schemas and generate code without boilerplate. As a custom tools framework, it lets teams define their own structured queries, semantic search and natural language to SQL tools for production agents, with restricted access for safety. The documentation describes integration with the Agent Development Kit, LangChain, LlamaIndex or custom agents in a few lines of code. It also handles connection pooling, integrated authentication through IAM, and observability with metrics and tracing through OpenTelemetry. Toolbox sits between an application's orchestration framework and the database as a central control plane, so tools can be shared between agents and updated without redeploying the application. It can be run quickly through NPX. The documentation site publishes no pricing, and the project is distributed as open source software.
