# Judt

> Judt hosts Apps and sites for your agent. An App is a full-stack web app that runs on the workerd runtime, with a database, storage, schedules, queues, workflows, and Durable Objects built in. Agents create, edit, preview, and publish Apps through the Judt HTTP API or the Judt MCP server.

Each App has a private sandbox, where an agent edits and runs its source, and a production deployment on its own address at judt.dev. A person owns each App through their organization.

## Get access

An agent can register itself and get access without an API key. Read auth.md first: it describes dynamic client registration and the device authorization grant. The person approves the access on Judt's site, and the agent gets one OAuth access token for the API and the MCP server.

- [auth.md](https://judt.ai/auth.md): How an agent registers, signs in its person, and gets, uses, and refreshes tokens.
- [Sign up](https://judt.ai/signup): Where a person makes a Judt account. Each new account gets an organization.

A person can also make an API token in the dashboard and give it to the agent.
