Alation Plugin

AI coding agent plugin for the Alation platform. Query data products, explore catalogs, automate workflows, curate metadata, and configure AI agents — all through natural language.

The latest plugin is always available from the Releases page.

Prerequisites

• Python 3.10+
• An Alation instance with OAuth client registration (see Step 2 below)

Getting Started

Step 1: Install the Plugin

Claude Code

Register the marketplace and install:

/plugin marketplace add Alation/alation-plugins
/plugin install alation@alation-plugins

Claude Cowork

Marketplace

1. Go to "Customize" in the sidebar.
2. Click the "+" icon next to "Personal Plugins" and select "Add marketplace"
3. Add marketplace by URL: https://github.com/Alation/alation-plugins
4. Install Alation

Note: After adding a marketplace, you can check for updates or re-install plugins by clicking the "+" icon next to "Personal Plugins" and selecting "Browse Plugins", then navigating to the "Personal" tab and selecting the alation-plugins marketplace

Zip File

1. Download alation.zip from the latest release.
2. Go to Customize in the sidebar.
3. Click the "+" icon next to "Presonal Plugins" and select "Upload plugin"
4. Drag and drop or browse files to the downloaded zip file to install

Codex Plugin

Register the marketplace and install:

codex plugin marketplace add https://github.com/Alation/alation-plugins.git
codex plugin add alation@alation-plugins

On first use, ask Codex to set up Alation. Codex will prompt for your Alation base URL and OAuth client ID, then use a manual OAuth flow where you open an authorization URL and paste the final redirect URL back into chat. Depending on your Codex sandbox settings, the CLI may ask for approval before making network requests to your Alation instance.

Codex Agent Skills / Gemini CLI

Install skills using the agent skills installer:

curl -fsSL https://raw.githubusercontent.com/Alation/alation-plugins/main/bin/install-agent-skills.sh | bash -s -- --scope user

This installs portable agent skills to ~/.agents/skills/, which both Codex and Gemini CLI read automatically. Each skill bundles the Alation CLI — no separate installation needed.

To install to the current project only:

curl -fsSL https://raw.githubusercontent.com/Alation/alation-plugins/main/bin/install-agent-skills.sh | bash -s -- --scope workspace

Snowflake Cortex Code

Install agent skills the same way as Codex / Gemini CLI above, then register the skills directory with Cortex:

cortex skill add ~/.agents/skills

Verify the skills are available:

cortex skill list

Other Platforms

Any agent that supports the Agent Skills format can use Alation skills. Run the install script above with --scope user or --scope workspace and point your agent at the resulting .agents/skills/ directory.

Step 2: Register an OAuth Client

The plugin uses OAuth to connect to your Alation instance. You (or an admin of your instance) will need to register an OAuth client if one doesn't exist already.

1. Follow the instructions in these docs.
2. Set the "Client Type" to public.
3. Add http://127.0.0.1:18722/callback as an allowed redirect URL.
4. Save the client ID — you'll need it in the next step.

Step 3: Authenticate

Ask your agent to set up the Alation plugin. It will prompt you for:

• Base URL — your instance URL, e.g. https://your-alation-instance.alationcloud.com
• Client ID — from Step 2

After that, it will open a browser window for you to log in.

Cowork users: The redirect page after login will not load. This is expected. Copy the full URL from that page and paste it back into the chat so Claude can finish authentication.

Usage Examples

Once you're set up, just ask in natural language. Here are some things you can try:

What marketing data do we have?

Search the catalog for anything related to "customer orders"

What was our total revenue last quarter?

Create an agent that can answer questions about our finance data

Send me a summary of last week's sales every Monday

Add a descriptions to the customer orders data product
