## What it does

This plugin ships MCP Toolbox's prebuilt `alloydb-omni` server as an extension for your agent. You get cluster management, SQL execution, schema browsing and troubleshooting without leaving the session. Claude, Codex and Gemini CLI are supported.

Have your connection settings ready before installing. `ALLOYDB_OMNI_DATABASE`, `ALLOYDB_OMNI_USER` and `ALLOYDB_OMNI_PASSWORD` are required; host and port fall back to `localhost` and `5432`. You also need a running AlloyDB Omni instance. The project is beta, so breaking changes can land before v1.0.

In Claude the plugin comes from a marketplace: add `anthropics/claude-plugins-official` first, then install the plugin itself. Run `/plugin list` to confirm the MCP server is up, or `/reload-plugins` right after installing.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin install alloydb-omni@claude-plugins-official
```
In the agent chat (not a shell):
```text
/plugin marketplace add google/skills
```
In the agent chat (not a shell):
```text
/plugin install alloydb-omni@google-plugins
```
In the agent chat (not a shell):
```text
/plugin marketplace add anthropics/claude-plugins-official
```

## When to use it
- spin up an AlloyDB Omni cluster and connect to it
- run a SQL query without opening psql
- read table schemas before touching application code
- generate data classes from existing tables
- track down a failing query or connection

## Example prompts
- Show me the schema of the `orders` table in AlloyDB Omni
- Run a query for orders placed in the last week
- Generate a data class for the `customers` table

# AlloyDB Omni

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

This repository packages [MCP Toolbox](https://github.com/googleapis/mcp-toolbox)'s prebuilt `alloydb-omni` server as a plugin/extension to interact with [AlloyDB Omni](https://docs.cloud.google.com/alloydb/omni/docs) instances. It can be used with various AI agents, including [Antigravity](https://antigravity.google/), [Claude Code](https://claude.com/product/claude-code) and [Codex](https://developers.openai.com/codex), to manage your databases, execute queries, explore schemas, and troubleshoot issues using natural language prompts.

## Why Use AlloyDB Omni?

- **Seamless Workflow:** Integrates seamlessly into your AI agent's environment. No need to constantly switch contexts for common database tasks.
- **Natural Language Queries:** Stop wrestling with complex commands. Explore schemas and query data by describing what you want in plain English.
- **Full Lifecycle Control:** Manage the entire lifecycle of your database, from creating clusters to exploring schemas and running queries.
- **Code Generation:** Accelerate development by asking your agent to generate data classes and other code snippets based on your table schemas.

## Prerequisites

Before you begin, ensure you have the following:

- One of these AI agents installed
  - Antigravity
     - [Antigravity CLI](https://github.com/google-gemini/gemini-cli) version **v1.6.0** or higher
     - [Antigravity 2.0](https://antigravity.google/product/antigravity-2) version **v2.0.0** or higher.
  - [Claude Code](https://claude.com/product/claude-code) version **v2.1.94** or higher.
  - [Codex](https://developers.openai.com/codex) **v0.117.0** or higher.
- An active AlloyDB Omni instance.

## Getting Started

### Configuration

Please keep these environment variables handy during the installation process:

*   `ALLOYDB_OMNI_HOST`: (Optional: localhost by default) The host of your AlloyDB cluster.
*   `ALLOYDB_OMNI_PORT`: (Optional: 5432 by default) The port of your AlloyDB cluster.
*   `ALLOYDB_OMNI_DATABASE`: The name of the database to connect to.
*   `ALLOYDB_OMNI_USER`: The database username.
*   `ALLOYDB_OMNI_PASSWORD`: The password for the database user.
*   `ALLOYDB_OMNI_QUERY_PARAMS`: (Optional) Additional query parameters.

### Installation & Usage

To start interacting with your database, install the extension for your preferred AI agent, then launch the agent and use natural language to ask questions or perform tasks.

For the latest version, check the [releases page][releases].
