## What it does

This plugin packages the prebuilt `oracledb` server from Google's MCP Toolbox. It lets the agent interact with database instances directly from the terminal. You can inspect schema definitions, examine execution plans, and generate application code based on existing table structures.

Setup relies on three primary environment variables: `ORACLE_CONNECTION_STRING`, `ORACLE_USERNAME`, and `ORACLE_PASSWORD`. You can also configure `ORACLE_WALLET` and toggle `ORACLE_USE_OCI` for thick-client setups. Without `SELECT` privileges on `V$` and `DBA_` views, diagnostic monitoring commands will fail. Note that the project is in pre-v1.0 beta.

## Install

### Claude Code (native platform)

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

## When to use it
- Inspect schema structures without leaving the terminal
- Analyze execution plans for slow queries
- Generate data models from existing table columns
- Track active database sessions and lock contention

## Example prompts
- List all tables in the current schema and describe their primary keys
- Check active sessions in Oracle Database and identify long-running locks
- Create Python dataclasses based on the schema of the `customers` table

# Oracle Database

> [!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 `oracledb` server as a plugin/extension to interact with [Oracle Database](https://www.oracle.com/database/) 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 Oracle Database?

- **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 Database Insights:** Monitor active sessions, analyze query plans, and manage tablespace usage using natural language.
- **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:
  - [Gemini CLI](https://github.com/google-gemini/gemini-cli) version **v0.6.0** 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
  - [Antigravity](https://antigravity.google) **v1.14.2** or higher
- Access to an Oracle Database instance.
- Oracle Database permissions:
  - `CREATE SESSION` for basic connectivity.
  - `SELECT` privileges on `V$` and `DBA_` views for monitoring and diagnostics.

## Getting Started

### Configuration

Please keep these settings handy during the installation process:

- `ORACLE_CONNECTION_STRING`: The connection string for your Oracle Database (e.g., `host:port/service_name` or TNS alias).
- `ORACLE_USERNAME`: Your Oracle database username.
- `ORACLE_PASSWORD`: Your Oracle database password.
- `ORACLE_WALLET`: (Optional) Path to the directory containing your Oracle Wallet files.
- `ORACLE_USE_OCI`: (Optional) Set to `true` to use the OCI (thick client) driver.

### 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].

<details open>
<summary id="antigravity">Antigravity</summary>

You can use either of these two agents for Antigravity:
- [Antigravity CLI](https://github.com/google-gemini/gemini-cli) version **v0.2.7** or higher
- [Antigravity 2.0](https://antigravity.google/product/antigravity-2) version **v0.2.7** or higher.
