Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to justpublish.ai, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Publishes AI-built static websites to a live public justpublish.site URL and lets an assistant read, update and list those sites.

What you can do: Publish a site from its files and get back its public address
Read the files of a published site and change a single file, putting the change live
List the sites on the signed-in account
Check whether a site is already served on its own custom domain
Load static guidance resources on the publish flow, file conventions and edit lifecycle
When to use it: Useful when an assistant generates a static website (HTML, CSS, JavaScript, images, fonts) and you want it online at a public address without setting up hosting, or when you need to edit files of an already published site.
Requirements: Remote Streamable HTTP endpoint; nothing to install. OAuth 2.1 sign-in with dynamic client registration is required, using a Google account or a code sent by email; no API key or client secret to paste. Sites must be static with index.html at the root, no build step or server code.

Before you install

Deploying and updating publish content to a public URL that anyone can open, and deploy replaces the site's files while update_site_file merges a change. Sites belong to the signed-in account, so the assistant acts with your account's publishing rights. Custom domains are connected separately from the dashboard.

Installation

In SourceWeft

Open Just Publish. in the dashboard and add it to a workspace.
Connect the required credentials. They are stored privately and never shown on public pages.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.justpublish%2Fjust-publish/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

README

Just Publish MCP Server

Publish and update the website you built with AI at a live public URL. Sign-in required.

Just Publish puts the website you built with AI live at a public address. Your assistant makes the files; Just Publish publishes them at a justpublish.site address that anyone can open, and keeps them there. You sign in once with your Just account, and every site belongs to the account that published it. A published site can later run at a domain you own.

Website: https://justpublish.ai
MCP endpoint: https://mcp.justpublish.ai/
Registry name: ai.justpublish/just-publish
Transport: Streamable HTTP (remote, nothing to install)
Authorization: OAuth 2.1 with dynamic client registration. The client opens a sign-in window the first time (Google or a code sent by email).

Connecting

Add the endpoint to your client's MCP servers and sign in when it asks:

json

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

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

The client discovers the authorization server from the endpoint, so there is no API key, client id or secret to paste. In Claude, add the connector at https://mcp.justpublish.ai/claude; in Claude Code:

Step-by-step guides for each assistant and editor are at https://justpublish.ai/install.

Tools

Tool	What it does
`deploy`	Publishes a site from its files and returns its public address.
`get_site_files`	Reads the files of a published site.
`update_site_file`	Changes one file of a published site and puts the change live.
`list_sites`	Lists the sites on the signed-in account.
`get_site_domain_status`	Says whether a site is on its own domain yet, with a link to the site's domain page. Changes nothing.

The account comes from the sign-in, so deploy takes no email address and the signed-in person's own sites need only a site_id.

Resources

Static Markdown guidance the client can load before it picks a tool:

Resource	Purpose
`just-publish-overview`	What Just Publish is and which tool to use when.
`just-publish-edit-lifecycle`	The read, edit and update loop.
`just-publish-file-conventions`	Paths, encoding, size limits, routing.
`just-publish-invariants`	`index.html` required; `deploy` replaces, `update_site_file` merges.

Agent skill

This repository also hosts the just-publish skill in the SKILL.md format, which teaches an agent the publish flow before it calls a tool. Add it, with the Just Domain skill, to any agent that reads Agent Skills:

To install this copy in Codex, give the skill installer this tree:

or copy skills/just-publish/ into ~/.codex/skills/ (or ~/.claude/skills/). The same package is listed for discovery at justpublish.ai/.well-known/agent-skills/index.json.

Good to know

Static sites only. HTML, CSS, JavaScript, images and fonts, with index.html at the root. No build step and no server code.
Your own domain. Connect a domain you own from the dashboard at justpublish.ai.

Tools

This server asks you to sign in, so SourceWeft could not read its tools without an account and has not indexed them. What a connected account sees can depend on that account and its permissions.

85% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
