Brave Search MCP Server: web results, images, videos, rich results, AI summaries, and more.
iter0 is installed from its publisher's own source and answers where it runs, so this marketplace is not in the path of a single call. There is no address here to send one to, and a panel that pretended otherwise would be showing you an answer we made up. Install it and call it from your own client — the Installation tab has the entry for each one.
What it does
Build and edit launch-ready websites for tech founders from a brief or an authorised reference.
Quickstart
# 1 — add it to Claude Code
claude mcp add --scope user --transport http iter0-mcp https://iter0.com/api/mcp
# 2 — ask your agent for something these tools do
# iter0_health, iter0_create_site, iter0_edit_site and 19 more
iter0 costs nothing on mcprush: there is no plan to choose here, no cap to set and nothing mcprush can bill you for.
Collected from a public index. Nobody has claimed this account, so nothing here was written by its author — claim it if it is yours.
Where are you running it?
Every route below installs the same thing and ends at the same approval screen. Nothing here runs on your machine and nothing runs on ours: this server answers at its publisher’s own address, and what you install is the connection straight to it.
This is a public server: it answers at its publisher’s own address and this marketplace is not in the path. Claude Code registers it in one command; --scope user makes it available in every project. The transport below is http, as the publisher's own manifest declares it.
claude mcp add --scope user --transport http iter0-mcp https://iter0.com/api/mcpReconnect, or start a new session, and the tools appear in the model’s tool list.
One config entry pointing straight at the publisher’s own address — this marketplace is not in the path, and nothing from this listing executes on your machine.
22 tools, with what each one reads, writes and reaches shown before you agree — the same list on every route above. Read the tool surface.

What the model actually sees. Descriptions are diffed on every release — see version history.
For developers integrating the iter0 API: check that the API and its developer contracts are reachable. Does not build or edit websites.
No parameter schema on file.
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 when the person confirms that quote, in the iter0 card or by saying yes in chat, and iter0_confirm_paid_action redeems it. The iter0 card shows the price, the b
| Parameter | Type | Required | Notes |
|---|---|---|---|
| prompt | string | no | The website goal and customer context. At most 32,000 UTF-8 bytes. |

| bindUrl | string | no | Optional customer evidence source. At most 2,048 UTF-8 bytes. |
| briefBuild | boolean | no | Develop the launch brief before building. |
| faithfulClone | boolean | no | Request an authorized identity-preserving clone. |
| directionId | string | no | A directionId from iter0_get_design_set_status; builds that exact direction, with no prompt or reference arguments. |
| confirmationVersion | integer | no | Compatibility marker sent by direction cards. It does not authorize spending. |
| variant | string | no | Normally empty. A new value such as "2" requests a fresh build of a request already made (for example after a failed build, or another version); it is quoted and uses a credit. |
| approvalId | string | no | Compatibility receipt for a quote already confirmed in iter0. New quotes are redeemed with iter0_confirm_paid_action. |
| quoteOnly | boolean | no | Return the price only; never starts or charges a build. |
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 chat (no designId), pass that page exactly as currentHtml; the revised HTML comes back and no saved design changes. Costs 0.5 credits. The first call returns a pr
| Parameter | Type | Required | Notes |
|---|---|---|---|
| prompt | string | yes | The focused edit instruction. At most 32,000 UTF-8 bytes. |
| currentHtml | string | no | A page the person pasted into the chat, used when there is no designId. A saved design is edited by designId; iter0 loads its page. At most 2,000,000 UTF-8 bytes. |
| referenceUrl | string | no | Optional visual reference. At most 2,048 UTF-8 bytes. |
| selectedAreas | array | no | — |

|---|---|---|---|
| runId | string | yes | The run ID returned by create_site. |
| includeHtml | boolean | no | Include the generated HTML when the build is done. |
| waitCursor | integer | no | Return new public build progress events after this cursor. |
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.
No parameter schema on file.
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 allowance. A paid request first returns a price quote and starts nothing; the designs start only when the person confirms that quote, in the card or by saying yes
| Parameter | Type | Required | Notes |
|---|---|---|---|
| prompt | string | yes | The user's business brief, keeping their facts and words. |
| directions | array | yes | — |
| businessContext | object | yes | — |
| variant | string | no | A new value requests a new batch, for example after a refunded failure; it is quoted again. |
| approvalId | string | no | Compatibility receipt for a quote already confirmed in iter0. New quotes are redeemed with iter0_confirm_paid_action. |
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; charges nothing.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| batchId | string | yes | — |
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 connected account, matches the same request and price, has not expired and has not been used. Work that fails is refunded.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| quoteId | string | yes | The reference of the price quote the person accepted. |
| name | yes | — | |
| arguments | object | yes | — |
| credits | number | yes | — |
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 iter0 websites and designs, not general design, colour, logo or branding advice, hosting elsewhere or domains. iter0 does not sell credits or take payment through C
| Parameter | Type | Required | Notes |
|---|---|---|---|
| cursor | string | no | nextCursor from the previous page. |
| query | string | no | Part of a design name to search for. |
| limit | integer | no | Designs per page. Defaults to 12. |
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 site") or shows whether a build they started is finished. query searches by name; nextCursor, passed back as cursor, gives the next page. Read-only. Covers only t
| Parameter | Type | Required | Notes |
|---|---|---|---|
| cursor | string | no | nextCursor from the previous page. |
| query | string | no | Part of a design name to search for. |
| limit | integer | no | Designs per page. Defaults to 12. |
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 prompt, loads the page itself, saves the edit as the design's current page, and the card offers Undo. Read-only. Covers only the person's own iter0 websites and
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | — |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | — |
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 with the same designId, versionId and that token, once the person agrees, restores it.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | — |
| versionId | string | yes | — |
| confirmationToken | string | no | — |
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.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | — |
| undoToken | string | yes | — |
| html | string | no | Ignored. Older cards still send it; iter0 restores its own kept copy. |
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 pages or sections that do not exist, leftover sample text (lorem ipsum, "your headline here", TODO notes, example.com addresses), contact forms whose messages woul
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | The saved design, from iter0_get_design or iter0_list_my_designs. |
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 one, iter0 uses the free address it suggests). Called without confirmationToken, nothing goes live: it returns the exact address and a confirmationToken. Calle
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | The saved design, from iter0_get_design or iter0_list_my_designs. |
| subdomain | string | no | The name for the address: name.iter0.app. Optional; only on the first call, and only when the person chose a name. |
| confirmationToken | string | no | Leave out on the first call. On the second call pass the token the first call returned, unchanged. |
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 with the same designId and that confirmationToken, the site goes offline. If the result says the outcome is unknown, iter0_publish_status shows whether the sit
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | The saved design, from iter0_get_design or iter0_list_my_designs. |
| confirmationToken | string | no | Leave out on the first call. On the second call pass the token the first call returned, unchanged. |
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 the saved version, and the free address on offer if it was never published.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | The saved design, from iter0_get_design or iter0_list_my_designs. |
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 (one saved design per page, grouped in a project) and returns its designId and one canvasUrl that shows every page as a frame. Later pushes with the same sourceId
| Parameter | Type | Required | Notes |
|---|---|---|---|
| sourceId | string | yes | A stable name for this website's source that you reuse on every push, for example github.com/acme/site or local:acme-site. |
| siteName | string | yes | The site's name as the person will see it in iter0. |
| designId | string | no | Optional check: the designId an earlier push returned for this sourceId. A mismatch changes nothing. |
| projectId | string | no | Optional, first push only: an existing iter0 project to put the pages in. Without it a new project named after the site is made. |
| pages | array | yes | — |
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 near (pageKey, route, designId) and, for element comments, whether that element is still on the current page (anchor.state) and whether the page changed after the
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | The canvas's designId from iter0_push_site, or any page's designId on it. Any other saved design the person owns also works. |
| cursor | string | no | nextCursor from the previous call. |
| limit | integer | no | Items per call. Defaults to 20. |
| includeResolved | boolean | no | Defaults to true. False leaves resolved comments and pins out and counts them in omitted. |
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 approves nothing. operationId makes a retry safe: the same operationId and text add the reply once. Pass the thread's version from iter0_get_canvas_feedback as e
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | The canvas's designId from iter0_push_site, or any page's designId on it. Any other saved design the person owns also works. |
| feedbackId | string | yes | A comment or pin feedbackId from iter0_get_canvas_feedback. |
| text | string | yes | — |
| operationId | string | yes | A new unique ID for this reply, reused only to retry it. |
| expectedVersion | integer | no | — |
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 nextOffset is not null, call again with it as offset and append. Check that version is the same on every part.
| Parameter | Type | Required | Notes |
|---|---|---|---|
| designId | string | yes | The canvas's designId from iter0_push_site, or any page's designId on it. Any other saved design the person owns also works. |
| pageKey | string | yes | A pageKey from iter0_push_site or iter0_get_canvas_feedback. |
| offset | integer | no | nextOffset from the previous part. Leave out for the first part. |
- Every tool — any call limit is its publisher’s, not ours
- No card, and mcprush charges nothing for it
- Runs at its publisher’s own address — this marketplace is not in the path
- Nothing to cap, because mcprush bills nothing
What counts against your monthly calls
| Tool | Unit | Calls used | Out of the allowance |
|---|
Nothing here is billable: mcprush charges nothing to install iter0 or to call it, at any volume.
Two independent axes, because powerful and malicious are different questions. The grade is threat only. The capability level is blast radius, and it is never a penalty on the grade — it is priced as one subtract-only term in the score, where you can see it.
| Term | Level | What it prices | Points |
|---|---|---|---|
| capability-exposure | moderate | capability blast radius (moderate) — client exposure if the model is manipulated | −3 |
| coverage-honesty | manifest | inspection depth (manifest) — how much of the target the scan could see | −4 |
What the scan could actually read
A grade is only as meaningful as its coverage, so the scanner publishes its own depth before it publishes its result.
The scan read each tool’s name, description, input schema and annotations exactly as the server listed them the last time it answered us; no code was reviewed. We ask the server again about once a month, and a list that changed is graded again.
The implementation source was not read — this reflects the declared tool metadata only.
Capability — what it could do if the model were manipulated
Tags derived from each tool’s schema and the implementation, not from what the tool calls itself. moderate is the level these add up to.

Toxic-flow graph
The lethal trifecta, checked as a graph rather than as a checklist: untrusted input, a sensitive source and an external sink have to meet before there is a path worth worrying about.
The public result for this release does not print the flow graph, so there is nothing to show here. That is not the same as "no paths were found": what the scan did read is above, under coverage.
Supply chain and provenance
This is the first scan of this surface here, so there is nothing yet to compare it against.
Every result on this tab comes from one deterministic pass over the published package — offline, rule by rule, and auditable line by line above. Same methodology version, same bytes, same score.
Release history
This is an address its publisher runs: which release it serves is theirs to choose, so there is nothing here to pin. The history below is for reading; the current release on file is 1.0.0.
No release note was published with this version.
One review per account, from a signed-in account that does not publish this listing. Nothing else is asked — you can say what you think before you install it. Publishers can reply once per review, and a review can be edited or deleted by whoever wrote it.
Any signed-in account that does not publish iter0 can review it, once — before installing it or after. A review from an account that has installed it is marked as one.
Nobody has reviewed this listing. The rating on the card is the mean of the reviews written here and nothing else, so there is no rating until somebody writes the first — which takes a signed-in account that does not publish it, and nothing else.
