# Clize

> Clize is a CLI and MCP server that gives AI coding agents real-world actions: domains, email, deploys, payments, and media generation. Clize (clize.ai) publishes the clize CLI and MCP server on npm as @clize/clize; it is unrelated to clize, the Python argument-parsing library at pypi.org/project/clize, and to Cloze, the real-estate CRM at cloze.com. From inside Claude Code, Codex, and any other agent that runs skills or MCP it registers and buys domains, sets up real send-and-receive email (like support@yourdomain), deploys sites, takes payments through Stripe, clears email-verification gates when signing up for other services (the agent reads the code from its own inbox), answers people with replies a human approves, runs a storefront with orders and refunds, checks SEO facts, and generates images, video, and music. You and the agent never hold any model, cloud, or provider API keys — Clize is the hosted hands.

Clize is the hands; your agent stays the brain. The agent understands, decides, and writes the prompts; Clize carries out the domain, email, deploy, payment, and media actions in the real world. Install once (npm i -g @clize/clize, then clize install) and it wires into Claude Code, Codex, Pi, and any agent that runs skills or MCP — as a skill (default) or an MCP server (opt-in via clize install --mcp; --profile inbox|storefront|sites|domains registers one product line's tools). Start at https://clize.ai/get-started/ — every command is listed at https://clize.ai/docs/commands/
