Just Publish MCP Server

Just Publish — MCP Server

Publish the website you built with AI to a live public URL — straight from chat, no setup.

Describe a site to your AI assistant — ChatGPT, Claude, Gemini, or any MCP-enabled client — and it publishes the site and hands back a live URL. No git, no CLI, no build step, no dashboard, and no login to fumble through. You hand it your files, it hands back a working link. Built for the person who made a site with AI and just wants it online.

• Website: https://justpublish.ai
• MCP endpoint: https://mcp.justpublish.ai/
• Registry name: ai.justpublish/just-publish
• Transport: Streamable HTTP (remote — nothing to install)

How it works

Call deploy with your files (HTML, CSS, JS, images) and an email. You get back a live url, a site_id, and an edit_token. Keep the token and you can update the same site anytime — either a full redeploy or a single-file edit. That's the whole flow.

Connecting

{
  "mcpServers": {
    "just-publish": {
      "type": "streamable-http",
      "url": "https://mcp.justpublish.ai/"
    }
  }
}

Then ask your assistant to publish a site. It returns the public URL.

Tools

Resources

Static markdown guidance the client can load into context before it picks a tool:

Plus a UI resource for the publish-result widget.

Agent Skill (ChatGPT / Codex / any SKILL.md runtime)

This repo also hosts the just-publish Agent Skill — a SKILL.md-format package that teaches an agent the full publish flow (including saving the edit_token and the email-verification step) before it ever calls a tool.

To install in Codex / ChatGPT, ask the assistant to install the skill from this tree:

https://github.com/just-done/just-publish-mcp/tree/main/skills/just-publish

(Codex's skill-installer takes a GitHub tree URL.) For a manual install, copy skills/just-publish/ into $CODEX_HOME/skills/ (default ~/.codex/skills/) or your runtime's equivalent (e.g. ~/.claude/skills/).

The same package is served for discovery scanners and other runtimes at justpublish.ai/.well-known/agent-skills/index.json (Agent Skills Discovery RFC, sha256-digested). The canonical source lives in the Just Publish server codebase; this tree is its published mirror and is kept in lockstep — the two are compared on every server deploy.

Who it's for

Non-technical builders and AI agents that generate a static site and need it hosted in one step. If you can describe a page, you can publish it.

Good to know

• No accounts required. Edit access is held by the edit_token returned at publish time — save it to update the site later.
• Static sites only — files in, URL out. No frameworks or build pipelines.
• Custom domains — connect your own domain at justpublish.ai.
