iter0
Build and edit launch-ready websites for tech founders from a brief or an authorised reference.
Installation
Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).
claude mcp add --transport http iter0 'https://iter0.com/api/mcp'{
"mcpServers": {
"iter0": {

iter0 MCP
Connect an AI agent such as Claude Code, Cursor or Codex to iter0, an AI website builder for tech founders. Through MCP, the agent can:
- build a launch website from a brief or from a reference site you are allowed to use;
- make one focused edit to a saved page;
- read your saved designs and their status;
- check a site for problems before you share it;
- publish a site to a free
name.iter0.appaddress, and take it offline again; - read and reply to comments left on an iter0 canvas.
Paid steps show a price quote first. Nothing is spent until you confirm the quote.
- Endpoint:
https://iter0.com/api/mcp(Streamable HTTP) - Setup page: https://iter0.com/mcp
- Developer docs: https://iter0.com/developers
- OpenAPI: https://iter0.com/openapi.json
- Agent summary: https://iter0.com/llms.txt
This repository holds connection instructions, a registry file and an agent skill. The server runs at iter0.com, and its source code is not published here.

}
}Codex (~/.codex/config.toml):

url = "https://iter0.com/api/mcp"If your client needs a different format, use its own steps for adding a Streamable HTTP server, and give it the endpoint above.
Sign in
Two tools work without signing in: iter0_health and iter0_get_developer_docs.
The other tools use your iter0 account through OAuth 2, with the scopes sites:read, sites:build and sites:edit. Your client opens a sign-in page the first time it needs one. The server publishes its protected-resource metadata at https://iter0.com/.well-known/oauth-protected-resource.
For direct API calls (not MCP), create a bearer token in your account settings: https://iter0.com/settings/api-keys. The API reference is at https://iter0.com/developers.
Tools
22 tools are live on the endpoint. Costs are from the tool descriptions.
No sign-in
| Tool | What it does |
|---|---|
iter0_health | Checks that the API and developer contracts respond. Does not build or edit. |
iter0_get_developer_docs | Returns the links for API docs, OpenAPI, MCP setup, authentication and support. |
Building (paid steps quote first)
| Tool | What it does | Cost |
|---|---|---|
iter0_create_site | Starts a website build from a brief, an authorised reference URL or a direction from a Show 3 set. Returns a quote first. | 1 credit |
iter0_edit_site | Makes one focused change to a saved page, or returns revised HTML for a page pasted into chat. Returns a quote first. | 0.5 credit |
iter0_show_three | Prepares three rough design directions from approved references. | 1 credit on a paid account; free accounts use their allowance |
iter0_confirm_paid_action | Starts a quoted request once the person has confirmed its price. | The quoted amount |
iter0_get_site_status | Checks a build's progress. Returns HTML only when asked. | Free |
iter0_get_design_set_status | Reads a Show 3 batch: status and the three directions. | Free |
Designs
| Tool | What it does |
|---|---|
iter0_list_my_designs | Lists saved designs, newest first, with search and paging. |
iter0_get_design | Reads one design: its name, link, section IDs and a short summary. Does not return the page code. |
iter0_open_builder | Opens your iter0 projects. Starts nothing and spends nothing. |
iter0_design_layout | Used by the iter0 card to outline a section. Not for direct use. |
Publishing and checks (free)
| Tool | What it does |
|---|---|
iter0_check_site | Lists problems before sharing: missing title or description, images without alt text, broken internal links, placeholder text, forms that would go nowhere. Changes nothing. |
iter0_publish_site | Puts a saved site live at name.iter0.app. Two steps: the first returns the address and a confirmation token, the second publishes. |
iter0_publish_status | Checks whether a site is live. |
iter0_unpublish_site | Takes a live site offline. The design and the address are kept. Two steps. |
iter0_undo_edit | Undoes the last saved edit, while it is still the current page. |
iter0_restore_version | Restores an earlier saved version. Two steps. |
Canvas feedback (free)
| Tool | What it does |
|---|---|
iter0_push_site | Puts finished HTML pages on your iter0 canvas so you can comment on them. Publishes nothing. |
iter0_get_canvas_feedback | Reads the comments and notes you left on the canvas. |
iter0_read_canvas_page | Reads one canvas page's HTML and version before a revision. |
iter0_reply_to_feedback | Adds a reply to a comment thread. Never resolves or approves anything. |
