# Cube

> Human-friendly, self-improving AI workflows.

Cube is a workflow platform where your agent builds, runs, and improves the underlying process. People step in occasionally to approve key decisions or inspect the work. Approval feedback and execution results help the agent decide what to change for the next run.

AI handles judgment; programs execute repeatable steps. Sheets, docs, and buttons make the work readable and actionable. Cube calls the persistent workspace containing these components a desk.

Cube runs the agent for you: open a desk, choose a Claude or Codex account, and Cube starts and manages that resident inside its own engine. Cube does not accept an incoming connection from an agent you run yourself — there is no MCP server to add to an external client. Public documentation can be read without a Cube account.
