Overview

Description from the maker (original English)

Publish HTML or markdown from your agent as a shareable link, with password or work-email walls.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Chat & email
  • You need to fill in: X-API-Key

Install

Pick the AI app you use, then copy the settings.

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http pubspace https://pubspace.ai/mcp --header 'X-API-Key: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "pubspace": {
      "url": "https://pubspace.ai/mcp",
      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "pubspace": {
      "type": "http",
      "url": "https://pubspace.ai/mcp",
      "headers": {
        "X-API-Key": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • X-API-Key secret HTTP header
    Your PubSpace API key (Settings → Connect your agent). Optional: without one, call create_account + verify_email to sign up from the chat.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

  • publish_page

    Publish a new HTML (or Markdown) page to the maker's PubSpace space and get back a live, shareable URL to hand to the human. Pages are unlisted by default — indexed by search engines only if the maker turns that on later (Pro); anyone with the link can view. Use this only for a b

  • update_page

    Replace the content of an existing page in place: the same URL serves the new content immediately, so links the human already shared keep working. Use this instead of publish_page whenever the page already exists. The previous version stays restorable from the dashboard for 7 day

  • list_pages

    List every page in the maker's space, newest first, with no paging: { total, pages: [{ id, title, url, project, views, live, workEmailGated, hasDraft, createdAt, updatedAt }] }. Read-only. Use it to find a page_id before update_page / get_page / unpublish_page / delete_page, or t

  • get_page

    Fetch one page by id: metadata always ({ id, title, url, project, views, live, workEmailGated, hasDraft, createdAt, updatedAt, visibility }), plus the stored HTML when include_html is true. Read-only. Use it to read a page before editing it with update_page; use list_pages to fin

  • unpublish_page

    Take a page offline without deleting it: its URL shows an "offline" notice to viewers, and the content, id, URL and view count are kept. Pass restore: true to put it back online at the same URL. Prefer this over delete_page when the human wants a page hidden or paused. Calling it

  • delete_page

    Delete a page: its URL stops working at once. The maker gets only a brief undo in the dashboard, then it is purged for good (there is no restore tool). Only use it when the human asked for deletion; to hide a page reversibly, use unpublish_page instead. Returns { ok, id, deleted

  • create_account

    Sign your human up for a free PubSpace space (no card) without leaving this session. Callable without an API key. Only call it after the human has told you their email and chosen a space name; never invent or guess either. Their pages will live at .pubspace.ai, so treat the name

  • verify_email

    Finish account verification with the 6-digit code PubSpace emailed to the human (ask them to read it to you). Publishing unlocks on success. Works in the session where create_account ran, or with an API key for an unverified account. Returns { ok, verified, subdomain }; fails wit

Common questions

Is PubSpace safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: X-API-Key

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.25.1) reached the registry 5 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud
