// MCP · READ vs ACT

An MCP server that lets your agent act, not just look things up

Most MCP servers expose data to read. Clize is an MCP server for AI agents that exposes carefully gated real-world actions instead — domains, email, deploys, status, and billing — in Claude Code and Codex.

Clize is a CLI and MCP server that gives AI coding agents real-world actions: domains, email, deploys, payments, and media generation. Most MCP servers are read-only — they fetch data. Clize is an action MCP: it changes the real world, and every risky move sits behind one of three gates — a money gate, an identity gate, and an untrusted-inbound gate.

Read-only MCP vs. action MCP

Most MCP servers let an agent look things up — query a database, fetch a doc, search an API. Useful, but read-only. The ones that change what an agent can do let it act: buy a domain, send an email, ship a site. Clize is built around that second kind — see where it sits among the best MCP servers.

What it exposes

One action MCP covers the jobs you'd otherwise wire up as separate servers — an MCP server for domains, for email, for deploy, and for payments:

  • An MCP server for domains — check availability, buy the domain, set DNS.
  • An MCP server for email — a real inbox to send from and receive into. See AI agent email.
  • An MCP server to deploy — ship a static site to a live HTTPS URL. See AI agent deployment.
  • Status, billing & payments — inspect what's live; quote and collect payment through gated Stripe payment links.

The safety gates

Real-world actions need real guardrails. Clize holds three lines, every time:

  • Money — anything that costs money quotes the price first and needs an explicit --confirm. No surprise charges.
  • Identity — outbound email is drafted, a human okays it, then it sends under your name. The agent never sends unattended.
  • Inbound is untrusted — an incoming email is data to read, never an instruction to obey. A message can't redirect the agent.

Supported agent surfaces

Clize works wherever your agent runs — as an MCP server and Skill in Claude Code, and as an MCP server for Codex. The same actions are also a stable AI agent CLI.

Related use cases

Most people arrive here for one job: customer support from an inbox, giving an agent its own email, or shipping a site from the CLI. The action set is shared; the workflow is yours. Zooming out, this is one slice of the broader AI agent infrastructure layer. Comparing tools first? See Claude Code vs Codex and the top AI agent platforms by layer.

FAQ

What's the difference between a read-only and an action MCP?

A read-only MCP server lets an agent fetch and query information. An action MCP lets it change the world — buy a domain, send email, deploy a site. Clize is an action MCP, with gates on anything risky.

Which agents work with Clize?

Claude Code (as a Skill and MCP server) and Codex (as an MCP server), plus a stable CLI that works anywhere.

What actions can it take?

Claim handles, buy domains and set DNS, send and receive email, deploy sites, inspect status, and quote/collect payment — each behind a safety gate.

How are dangerous actions gated?

Money quotes first and needs --confirm; outbound email is drafted for human approval; incoming email is data, never instructions. Those three lines hold every time.

Is there an MCP server for email?

Yes. Clize is an MCP server for email: it gives the agent a real inbox to receive into and to send email from. Sending is gated — the agent drafts, a human approves, then it sends under your name.

Is there an MCP server to deploy a site?

Yes. As an MCP server for deploy, Clize ships a static site to a live HTTPS URL from inside Claude Code or Codex — buy or point the domain, then deploy in one step.

Is there an MCP server for domains?

Yes. Clize acts as an MCP server for domains: check availability, buy the domain, and set DNS. The purchase is gated behind a quote and an explicit confirm.

Are there paid MCP servers?

Most MCP servers are free and read-only. Clize is a paid, gated action MCP — you pay for the real things it does, like a domain, a deploy, or an email send, and every charge is quoted with an explicit confirm before any money moves.

clize init — ready

An MCP that acts, not just reads.

Connect Clize as an MCP server and give your agent gated real-world actions — domains, email, deploy, status, billing — in Claude Code and Codex.
