add_component
Add a library component
Insert a component from the site's shared library into one or more existing pages, INSTEAD of hand-writing the markup yourself — the classes are already styled and themed to this site's colours. Choices: sc-page-title (the page's one <h1>), sc-gallery (cross-fading photo reel — needs 'images'), sc-info-tiles (title + picture + text sections — needs 'tiles'), sc-instructions (numbered/titled steps, optionally with a button each — needs 'tiles'), sc-event (one dated thing: a class, a session, an opening — needs 'title'), sc-btn (a link styled as a button — needs 'label'). NOT offered: sc-header/sc-footer (the site's own shell already emits those) or sc-hero (placed once, on the home page, by the site's own build). 'anchor' says where it goes: {"type": "heading", "value": "<text on the page>", "position": "after"} (default), {"type": "id", "value": "<element id>", "position": "after"}, {"type": "main_end"} (append at the end of the page), or {"type": "replace", "value": "<class of an existing sc-* block>"}. 'pages' is "all" or a list of paths from list_site_files. A page whose anchor doesn't match comes back in 'findings' with what's wrong and the fix — other pages in the same call still get the component. Follow with publish_site.

create_site
Create a new site
Build a brand-new hosted website from a plain-language description. RETURNS IMMEDIATELY with status 'building' — the site takes about 2-3 minutes and is NOT ready when this returns. Tell the user where it will be (expected_url) and poll get_build_status with the returned claim_token. NEVER call create_site a second time for the same site: each call builds another one. Works WITHOUT signing in: an unauthenticated call builds a guest site and returns a claim_url — the user signs up free (no card) at that link to keep it; unclaimed guest sites are deleted after 72 hours. Signed in, the site lands directly on the connected account (free tier: one site, no card).
Input schema
{'type': 'object', 'required': ['site_name', 'description'], 'properties': {'template': {'enum': ['local-services', 'restaurant', 'shop', 'portfolio', 'classes', 'community'], 'type': 'string', 'description': 'Starting template (guest builds; default local-services).'}, 'site_name': {'type': 'string', 'description': "Short human name for the site, e.g. 'Whitney Apparel'."}, 'description': {'type': 'string', 'minLength': 12, 'description': "What the site is for. MINIMUM 12 CHARACTERS — a bare 'bike shop' is rejected. Say what the business is, where it is, and what the site should include; the AI builds directly from this, so more detail means a better first result. Good: 'Oak Barrel Coffee, a small-batch roaster in Turlock CA — our story, three coffees with tasting notes and prices, and a contact form.' If the user was vague, ask them one question before calling this rather than sending two words."}, 'contact_email': {'type': 'string', 'description': "Optional, guest builds only: the user's email — we send the site link and a reminder before the unclaimed site expires."}}}
edit_site
Edit site (AI developer)
Ask sitectrl's AI editor to change an existing site ('add a contact page', 'make the hero darker'). Edits land in the site's draft; the first build of a brand-new site goes straight live. Returns what changed plus the draft URL.
Input schema
{'type': 'object', 'required': ['slug', 'instruction'], 'properties': {'slug': {'type': 'string'}, 'instruction': {'type': 'string', 'description': 'The change to make, in plain language.'}}}
get_analytics
Get site analytics
The site's private first-party traffic: pageviews/visitors/sessions/clicks totals, top pages, referrers, devices. Windows: 24h, 7d, 30d.
Read only
Input schema
{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string'}, 'window': {'enum': ['24h', '7d', '30d'], 'type': 'string'}}}
get_build_status
Check a site build
Check whether a site started by create_site has finished. Pass the claim_token create_site returned. Works WITHOUT signing in. Poll this every 30-60 seconds rather than calling create_site again — a second create_site call builds a SECOND site.
Read only
Input schema
{'type': 'object', 'required': ['claim_token'], 'properties': {'claim_token': {'type': 'string', 'description': 'The claim_token from create_site.'}}}
get_site
Get site details
Details for one site: live URL, draft URL, status.
Read only
Input schema
{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string', 'description': "The site's slug from list_sites."}}}
list_site_files
List site files
List the files in a site's draft tree (paths + sizes).
Read only
Input schema
{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string'}}}
list_sites
List my sites
List the user's sitectrl sites with their live URLs and hosting platform.
Read only
Input schema
{'type': 'object', 'properties': {}}
publish_site
Publish to live site
Publish the site's draft to the LIVE site (hosted sites). A snapshot of the previous live version is taken first, so it's undoable.
Destructive
Input schema
{'type': 'object', 'required': ['slug'], 'properties': {'slug': {'type': 'string'}}}
read_site_file
Read a site file
Read one file from a site's draft tree (text, or base64 for binary; 512 KB cap).
Read only
Input schema
{'type': 'object', 'required': ['slug', 'path'], 'properties': {'path': {'type': 'string'}, 'slug': {'type': 'string'}}}
search_domains
Search domains
Search real domain availability + prices (com/net/org/co/io/site and more). Available results include a purchase_url — hand it to the USER to complete checkout; the connector never spends money. Purchased domains connect to their sites in one click.
Read only
Input schema
{'type': 'object', 'required': ['query'], 'properties': {'query': {'type': 'string', 'description': "Domain or name to check, e.g. 'sierratrailcoffee.com'."}}}
whoami
Who am I
The connected sitectrl account: email, plan status, free-site slot, and credit balance.

Input schema
{'type': 'object', 'properties': {}}
write_site_files
Write site files
Push files (HTML/CSS/JS/images) into a site's DRAFT — use this when YOU are writing the code yourself instead of asking sitectrl's AI. Text files go in 'content'; binary files (images/fonts) in 'content_base64'. Max 40 files/call, 2 MB/file. Keep the <script defer src="sc-track.js"></script> include on every HTML page (the site's built-in private analytics — publish re-adds it if missing). Use clearly-marked placeholder contact info unless the user provided real details. For working forms, POST to /_sc/form/submit with a hidden _form name field — submissions reach the owner's dashboard + email (never use mailto:). Every HTML file is checked before it's written (DOCTYPE, charset, and any invariant this site has declared) — a file that fails is refused and comes back in 'refused' with what's wrong and the exact fix; other files in the same call still write. Follow with publish_site to go live.
