Just Publish MCP Server

Publish the website you built with AI to a live public URL, straight from chat, with 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. 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.

{
  "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

Tool

What it does

deploy

Publish a new static site (HTML/CSS/JS/images), or fully replace an existing one. Returns the live URL, a site_id, and an edit_token.

get_site_files

Read a published site's files so the assistant can make a targeted edit. Requires site_id + edit_token.

update_site_file

Change one or a few files in place (merge). Requires site_id + edit_token.

Resources

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

just-publish-overview

What Just Publish is and which tool to use when.

just-publish-edit-lifecycle

The read → edit → update loop.

just-publish-file-conventions

Paths, encoding, size limits, routing.

just-publish-invariants

index.html required; deploy replaces vs. update_site_file merges.

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

  • Static sites only. Files in, URL out. No frameworks or build pipelines.

  • Custom domains. Connect your own domain at justpublish.ai.
