Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
https://iter0.com/api/mcpNot in Muse's Connectors list yet. Muse can still use it: its page gives you a request to paste into Muse.
iter0 is a remote MCP server, so any assistant that can add a custom connector by link can use it. Same link, same tools.
In ChatGPT, open Settings, then Connectors (called Apps & Connectors on some accounts).
Under Advanced settings, switch on Developer mode. That is what lets you add a connector by link.
Choose Create, give it a name, paste the link as the MCP server URL, and save. If it needs a sign-in, ChatGPT asks for it here.
Start a chat, open the tools menu, pick the connector, and ask. ChatGPT asks before it runs a tool the first time.
Custom connectors need a paid ChatGPT plan, and on Team, Enterprise and Edu accounts only an admin can add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in ChatGPT
In Claude, open Settings, then Connectors.
Choose Add custom connector, give it a name, and paste the link.
If it needs a sign-in, Claude sends you to it. Then turn the connector on in a chat from the tools menu and ask.
Custom connectors are available on paid Claude plans; on Team and Enterprise accounts an admin may need to add them. Our "Working" label means the server answered us; it cannot tell whether your plan lets you add it. All connectors that work in Claude

Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.
iter0_healthFor developers integrating the iter0 API: check that the API and its developer contracts are reachable. Does not build or edit websites.iter0_create_siteBuild 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 when the person confirms that quote, in iter0_edit_siteMake 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 chat (no designId), pass that page exactlyiter0_get_site_statusCheck an authenticated website build; request HTML only when needed.iter0_get_developer_docsReturn 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_threePrepare 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 allowance. A paid request first returns a iter0_get_design_set_statusRead 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; charges nothing.iter0_confirm_paid_actionStart 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 connected account, matches the same request and iter0_open_builderOpen 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 iter0 websites and designs, not general desiiter0_list_my_designsList 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 site") or shows whether a build they startiter0_get_designRead 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 prompt, loads the page itself, saves theiter0_design_layoutUsed 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_versionRestore 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 with the same designId, versionId and thiter0_undo_editUndo 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_siteCheck 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 pages or sections that do not exist, leftoviter0_publish_sitePuts 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 one, iter0 uses the free address it sugiter0_unpublish_siteTakes 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 with the same designId and that confirmiter0_publish_statusChecks 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 the saved version, and the free address oiter0_push_sitePut 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 (one saved design per page, grouped in a priter0_get_canvas_feedbackRead 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 near (pageKey, route, designId) and, for eiter0_reply_to_feedbackAdd 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 approves nothing. operationId makes a retiter0_read_canvas_pageRead 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 nextOffset is not null, call again withhttps://iter0.com/api/mcpNot in Muse's Connectors list yet, but Muse can still use it.

At the last check (October 29, 2026, 23:31 UTC) the endpoint was working, answering in 179ms. It is checked every 15 minutes.
It was screened on October 29, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
It exposes 22 tools, including iter0_health, iter0_create_site, iter0_edit_site, iter0_get_site_status. For example, you could ask Muse: "Build me a professional website for my SaaS startup from a brief description of what we do"
