Installation & Setup

Install CLI

Download the CLI and authenticate with Ellf.

Connect

Connect Ellf to your coding assistant like Claude Code.

Set up your cluster

Launch your private data processing cluster.

Installation

Make sure you have Python 3.10+ installed and use the following command to install the client. It’s recommended to use a virtual environment.

Install CLI client

$pip installellf-cli

This installs the CLI that you and your coding agent can use to set up projects with Ellf, run tasks, actions and agents, and manage your cluster. It also sets up everything you need for your local development environment. Next, you can authenticate and connect Ellf to your coding assistant.

Claude Code Anthropic

Logging in with the --claude flag downloads and sets up everything that’s needed for the Claude Code integration. The custom Ellf skills for the different modules should then show up in your slash commands.

$ellflogin--claude

Other coding assistants

In order to use Ellf, your coding assistant needs to support adding custom skills via Markdown files and MCP server integration. If your coding assistant of choice is compatible, you can always copy over the skill files manually and add the Ellf MCP server.

Note that we’ve currently only tested Ellf with the coding agents and models listed here, so we cannot guarantee that it will work as intended with other models and setups.
