## What spanner does, in the publisher's words

> [!NOTE] > Currently in beta (pre-v1.0), and may see breaking changes until the first stable release (v1.0).

This repository packages MCP Toolbox's prebuilt spanner server as a plugin/extension to interact with Google Cloud Spanner instances. It can be used with various AI agents, including Antigravity, Claude Code and Codex, to manage your databases, execute queries, explore schemas, and troubleshoot issues using natural language prompts.
