Overview
What is Mythex MCP?
Mythex is an AI app builder (made in Dubai). Its remote MCP server lets Claude, Cursor or Codex build and ship full-stack web apps in a Mythex cloud sandbox, while you watch the live preview in the browser.
What the client can do
- Create or open projects and wake a cloud sandbox
- Read, write, edit and search files; run
bash - Start a preview and read its logs (
set_run_config,start_preview,get_preview) - Set secrets you provide (keys are listed back, values never are)
- Add a Postgres database and file storage, create checkpoints, publish
- Run a Playwright browser script and get screenshots back in chat
- Export or import code, sync with GitHub, connect a custom domain
Every tool result includes a workspace_url to watch the project live in Mythex.
