What it does

iter0 is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

No capability identified yet from its description.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

22 tools offered to AI assistants

iter0_health · For developers integrating the iter0 API: check that the API and its developer contracts are reachable. Does not build or edit websites.
iter0_create_site · Build a new website in the person's iter0 account from a brief, a reference URL they are allowed to use, or a directionId from their Show 3 set. Costs 1 credit. The first call returns a price quote and starts nothing; the build starts only
iter0_edit_site · Make one focused change to a saved iter0 design: pass its designId and the change as prompt. iter0 loads the current page itself and saves the edit as the design's current page; the card offers Undo. For a page the person pasted into the ch
iter0_get_site_status · Check an authenticated website build; request HTML only when needed.
iter0_get_developer_docs · Return iter0's official links for its API documentation, OpenAPI spec, MCP setup, authentication and support contact. Use when someone asks where to find them. Read-only; does not build or edit websites.
iter0_show_three · Prepare three rough draft website design directions for the person's business from approved design references; pass the brief and a name and short summary for each direction. Costs 1 credit on a paid account; free accounts use their free al
iter0_get_design_set_status · Read a Show 3 batch. Returns its running or failed status, or when done three directions, each with a stable directionId, title, one-line summary, screenshot URL, preview link and the iter0_create_site arguments that build it. Read-only; ch
iter0_confirm_paid_action · Start a quoted iter0 request once the person has confirmed its price: pass the quote's confirmation (quoteId, name, arguments, credits) unchanged, and exactly the quoted credits are spent. iter0 checks that the quote belongs to the connecte
iter0_open_builder · Open the person's iter0 projects: their recent designs, search and a box to start a new website. Use when they ask to open iter0 or see their iter0 projects. Read-only; starts nothing and spends no credits. Covers only the person's own iter
iter0_list_my_designs · List one page of the person's saved iter0 designs, newest first, with each design's name and link; the card shows their previews. A finished build appears here as a saved design, so this finds a design they name (for example "the Shiplog si
iter0_get_design · Read one of the person's iter0 designs: its name, link, section IDs and labels, and its headline and a short summary as text; the card shows the design. The page's code is not returned. iter0_edit_site takes this designId and the change as
iter0_design_layout · Used by the iter0 card. Returns a light copy of an owned design's page (images and scripts removed) in widget-only metadata, so the card can outline a section when the person points at the preview. Read-only.

iter0_restore_version · Restore an earlier saved version of the person's site (a versionId from iter0_get_design). Free. Two steps: a call without confirmationToken changes nothing and returns which version replaces which, with a confirmation token; a second call
iter0_undo_edit · Undo the last saved edit from the iter0 card. Free. Puts back the exact page from before that edit, which iter0 kept, only while the edit is still the design's current page and the undo has not expired.
iter0_check_site · Check a saved site for problems before the person shares it. Free and read-only: it changes nothing and uses no credits. Pass the designId. It lists, in plain words, a missing page title or description, images with no alt text, links to pag
iter0_publish_site · Puts a saved site live at its own free address, name.iter0.app, so anyone can open it. Free: it uses no credits. Takes the designId and, optionally, a name for the address (lowercase letters, numbers and hyphens, 3 to 63 characters; without
iter0_unpublish_site · Takes a live site offline: its address stops working. Free. The saved design and the address are kept, so the site can be published again later. Called with only the designId, nothing changes and it returns a confirmationToken. Called again
iter0_publish_status · Checks whether a saved site is live. Read-only: it changes nothing and uses no credits. Returns whether the site is published, when iter0 last confirmed that the address loads (an earlier check, not one made now), whether the live copy is t
iter0_push_site · Put a website you built, as finished HTML pages, on the person's iter0 canvas so they can comment on it, ask questions and leave notes there. Free: it uses no credits and publishes nothing. The first push for a sourceId creates the site (on
iter0_get_canvas_feedback · Read what the person left on an iter0 canvas: comment threads with their replies (pinned to a page element, a page, a note or a spot), sticky notes, text, shapes and labelled arrows, and durable pins. Each item names the page it is on or ne
iter0_reply_to_feedback · Add a reply to one comment thread or pin on the person's iter0 canvas, for example to answer their question or say what you changed. Free. It only appends the reply, marked as an agent's: it never resolves, reopens or deletes anything and a
iter0_read_canvas_page · Read the current HTML of one page on an iter0 canvas, with its version, so you can merge the person's own edits before pushing a revision. Free and read-only. A large page comes in parts: html holds the characters from htmlOffset, and while

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
