MCP Toolbox for Databases is an open source Model Context Protocol (MCP) server that connects your AI agents, IDEs, and applications directly to your enterprise databases.

It serves a dual purpose:

1. Ready-to-use MCP Server (Build-Time): Instantly connect Gemini CLI, Google Antigravity, Claude Code, Codex, or other MCP clients to your databases using our prebuilt generic tools. Talk to your data, explore schemas, and generate code without writing boilerplate.
2. Custom Tools Framework (Run-Time): A robust framework to build specialized, highly secure AI tools for your production agents. Define structured queries, semantic search, and NL2SQL capabilities safely and easily.

This README provides a brief overview. For comprehensive details, see the full documentation.

[!IMPORTANT]
Repository Name Update: The genai-toolbox repository has been officially renamed to mcp-toolbox. To ensure your local environment reflects the new name, you may update your remote: git remote set-url origin https://github.com/googleapis/mcp-toolbox.git

[!NOTE] This solution was originally named “Gen AI Toolbox for Databases” (github.com/googleapis/genai-toolbox) as its initial development predated MCP, but was renamed to align with the MCP compatibility.

Why MCP Toolbox?

• Out-of-the-Box Database Access: Prebuilt generic tools for instant data exploration (e.g., list_tables, execute_sql) directly from your IDE or CLI.
• Custom Tools Framework: Build production-ready tools with your own predefined logic, ensuring safety through Restricted Access, Structured Queries, and Semantic Search.
• Simplified Development: Integrate tools into your Agent Development Kit (ADK), LangChain, LlamaIndex, or custom agents in less than 10 lines of code.
• Better Performance: Handles connection pooling, integrated auth (IAM), and end-to-end observability (OpenTelemetry) out of the box.
• Enhanced Security: Integrated authentication for more secure access to your data.
• End-to-end Observability: Out of the box metrics and tracing with built-in support for OpenTelemetry.

Quick Start: Prebuilt Tools

Stop context-switching and let your AI assistant become a true co-developer. By connecting your IDE to your databases with MCP Toolbox, you can query your data in plain English, automate schema discovery and management, and generate database-aware code.

You can use the Toolbox in any MCP-compatible IDE or client (e.g., Gemini CLI, Google Antigravity, Claude Code, Codex, etc.) by configuring the MCP server.

Prebuilt tools are also conveniently available via the Google Antigravity MCP Store with a simple click-to-install experience.

1. Add the following to your client's MCP configuration file (usually mcp.json or claude_desktop_config.json):

   {
     "mcpServers": {
       "toolbox-postgres": {
         "command": "npx",
