What it can do

Tool names and descriptions exactly as the server reported them on Nov 11, 2026. The maker wrote them, not us; we show them as plain text.

  • publish_page Looks like an instruction to the AI

    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, comments: { total, open }, createdAt, updatedAt }] }. Read-only. Use it to find a page_id before update_page / get_page / unpubli

  • get_page

    Fetch one page by id: metadata always ({ id, title, url, project, views, live, workEmailGated, hasDraft, comments: { total, open }, 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_

  • 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

  • list_comments

    Read the comments people left on a page: { page_id, url, commentsEnabled, threads: [{ id, resolved, on, comments: [{ id, author, body, createdAt }] }] }. Each thread is a pin someone dropped on the page; `on` is the text of the element they clicked, so you can tell what the comme

  • resolve_comment

    Mark a comment thread resolved (or reopen it with resolved: false) after you have addressed it. The pin turns grey and drops out of the open list for everyone; nothing is deleted. Returns { ok, page_id, thread_id, resolved }. Fails with thread_not_found if the id is not an open-o

  • set_comments

    Turn click-to-pin comments on or off for a page. While on, anyone who can view the page can click a spot on it to comment once they sign in with their email (on a work-email-locked page, their viewing sign-in is enough); the maker gets an email per comment. Off hides comments wit

  • 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

  • claim_page

    For pages published without an API key (previews): ask PubSpace to email your human one link that keeps every page under a claim token. Callable without an API key. Only call it after the human has told you their email; never invent or guess one. Opening the link shows a Keep but

Common questions

Is PubSpace safe?

It passed 1 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 10 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 Business and above.

What can I use instead?

In the same category: Inbox Zero, Agent-Native Chat, draw.io
