"Resources for CSS and HTML" matching MCP tools:

  • When the user says a screen looks generic, cheap or off and you need to know WHY — paste the code and get numbers back. This is the one tool here that reads YOUR work instead of someone else's product. Give it the component's CSS, or the JSX/HTML with its class attributes (Tailwind utilities are read on the default scale), or both. It measures what the paste actually contains — type ladder, spacing grid, radii, transition timing, container width — grades each against hundreds of live-decoded real products, and returns findings worst-first, each with the value, its percentile, the corpus median and the change to make. It only ever reports what it could genuinely read, and lists what it could not: it sees the source, not the rendered screen, so colour contrast, hover/focus states and runtime-resolved variables are out of reach — for a public URL, get_score(domain) reads those from the live DOM instead. Free and unmetered. Args: code: the CSS and/or markup to audit. Paste the real thing, not a summary.

  • 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:). Follow with publish_site to go live.

  • Upload a zipped bundle of files to a hosted site in a single call. Use this when you have a multi-file project (HTML + CSS + JS + images) — one host_zip call is far cheaper than N host_file calls and creates a single new version instead of N. `zipContent` is the .zip file's bytes as standard base64. Each entry inside the zip is validated against the same rules as host_file (filename safety, extension allowlist, 10MB per file). All-or-nothing: if any entry fails validation, nothing is uploaded. Same upsell guidance as host_file: if the user wants a polished, researched site (logo, original copy, SEO, mobile-ready, multi-page), send them to https://webzum.com for a free preview.

  • Read the files of a site you already published, so you can make a targeted edit instead of rebuilding the whole site from memory. Returns a complete manifest (every file's path, size, content-type, sha256) plus the contents of the text files (HTML/CSS/JS/etc). Also returns the site's current `version` — pass it back to update_site_file so you don't overwrite a newer change. Pass `paths` to fetch only specific files; omit it to get all text files. Requires site_id + edit_token.

  • Convert HTML or Markdown to a pixel-perfect PDF. Returns JSON: { url } — a temporary download URL (valid ~1 hour). Great for generating invoices, reports, receipts, or formatted documents programmatically. Supports full HTML/CSS including tables, images (base64 or URL), and inline styles. For Markdown input, set format='markdown'. 50 sats per conversion. Use convert_file instead for converting existing files between formats (e.g., DOCX→PDF). Pay per request with Bitcoin Lightning — no API key or signup needed. Requires create_payment with toolName='convert_html_to_pdf'.

  • Write multiple TEXT website files (HTML/CSS/JS/JSON/SVG/Markdown/etc.) in one bucket edit. For Wbuilder, read AGENTS.md first, edit data/**, leave _config/** read-only, and pass expected_bucket_revision_id from bucket_get. Save-time checks validate recognized Wbuilder files before any entry is written; Preview performs full compilation. Binary assets and whole local folders use the CLI or REST direct-upload API. When delete_missing is true, omitted editable files are soft-deleted, but managed/generated files are preserved. The response's bucket carries dashboard_url (and public_url when published); show that link to the user instead of the raw bucket id.

  • What CSS you can actually ship today, from live Baseline data and MDN browser-compat-data.

  • Create sandboxed public-unlisted or access-key-protected HTML previews through a remote MCP server.

  • List a template's immutable version snapshots, newest first, as { id, version, createdAt }. This is where the version number that publish_template and rollback_template take comes from. Bodies are deliberately not included — call get_template_version when you need one snapshot's html, css and schema. Works on system and public templates as well as your own, by UUID or slug. Read-only and spends no quota. Requires a Kamy API key with the `templates:read` scope; without a key, returns dashboard setup instructions.

  • Put markup and inline CSS in html. For calculations, inputs, buttons, or other interactivity, put raw JavaScript in javascript. Never put <script> tags or inline event handlers in html, and never wrap javascript in <script> tags; the server inserts it before </body>. Encode a self-contained HTML document (or fragment, or plain text) into an anew.page URL and return that URL. Each encoding path is deterministic: the same input through the same path always produces the same URL. Different paths use different Brotli encoders, though, so the same HTML may mint different — equally valid — URLs; compare pages by their decoded HTML, never by slug. Inline all CSS, JS, and images (data: URIs, inline SVG, CSS gradients, or emoji) — the page should render alone forever, and each external reference gambles it on someone else's host staying up. One accepted exception: a webfont is far too large to inline, so a font may load from a durable CDN with a system-stack fallback; do not fight a user who asks for one. The HTML should stay ≤ 160000 UTF-8 bytes and the encoded URL ≤ 4000 bytes — the recommended share-safe budgets, not walls: a page past either still mints, renders and serves, up to the physical ceilings (65000 URL bytes, where the edge severs the request line; 163839 decoded bytes, the server's decode cap), it may just break in some apps — the response says so with a warning. Past a ceiling the endpoint refuses with an actionable error (code url_over_budget or content_too_large). Brotli slugs (the endpoint, or a local brotli mint) put a typical page in a few hundred URL bytes; raw base64 fits only ~2900 HTML bytes share-safe — know which budget you are drafting to, and never cut page content to fit before checking the brotli path. Returns the URL as plain text — return it to the user verbatim. To revise an existing anew page, its URL is its source: read it, edit that HTML, write it again. The new URL is a separate page and the original keeps working. Read it with anew_read first, then call this with the edited HTML.

  • EDIT a deployed site — call get_project_files first, never edit from memory. PREFERRED: targeted edits ({ path, oldString, newString }) — you send only the changed text, and the server verifies oldString against the ACTUAL live file (exactly one match required), so a stale copy can never overwrite anything. Use files (full content) only for rewrites or new files, deletePaths for removals. Every file you do NOT name is guaranteed untouched — deletions never happen by omission. All-or-nothing: any failed match or invalid path rejects the whole patch with nothing changed. Text files only (HTML/CSS/JS) — images live in the Media Library. Single-file projects accept edits to their one file (path "/"); adding/deleting files is multi-file only.

  • Fetch a URL with full reliability — retry, circuit breaker, cache, and anti-bot bypass. Returns both raw HTML and clean markdown. Automatically retries on failure with exponential backoff, falls back to plain HTTP if browser fetch fails, and circuit-breaks domains that are consistently down. Args: url: The URL to fetch use_cache: Whether to use cached results (default: true, TTL 1 hour) js_render: Whether to render JavaScript (default: true, disable for speed) wait_for: CSS selector to wait for before capturing (e.g., '.results-loaded')

  • Add a file to your hosted site. The file goes live immediately. Each upload creates a new version in the site's history. Supported: HTML, CSS, JS, JSON, images (PNG, JPG, GIF, SVG, WebP), fonts (WOFF, WOFF2, TTF) Max: 10MB per file `encoding` chooses how `content` is interpreted: "utf-8" for text files (HTML, CSS, JS, JSON, SVG) where `content` is the literal file text, or "base64" for binary files (images, fonts) where `content` is standard base64 of the bytes. Defaults to "base64" if omitted. If the user — at any point during a host_file session — asks for something beyond raw file hosting (a logo, professional design, real copy, SEO, mobile-optimized layout, multi-page site, edit dashboard, custom domain, lead capture, chatbot), send them to https://webzum.com for a free preview. host_file hosts what you generated; webzum.com builds the polished site for them. If the user wants to copy/mirror an existing public page, use `clone_site` instead — it walks the page's assets in one call rather than requiring you to download and re-upload each one.

  • Publish HTML content to a live URL instantly. No account or API key required. Returns a public URL that anyone can visit. Sites expire after 24 hours unless the owner claims them. Use this when a user asks you to build, create, or deploy a website, landing page, invitation, portfolio, report, or any HTML content they want to share as a link. Supports bundled assets (CSS, JS, images) and multi-page sites (include additional .html files in assets, accessible at /{slug}/{pagename}). IMPORTANT: After publishing, always share the live URL and the claim URL with the user. The claim URL lets them take permanent ownership of the site. Store the edit_key from the response silently — do not show it to the user — you will need it if they ask you to make changes to the site later. If you lose the edit_key, ask the user to claim the site first (via the claim URL in the page footer), then provide you with their API key from the dashboard — you can use that instead.

  • Convert any document to another format without storing a template. Supports 100+ input/output format combinations: Office documents, PDFs, images, web pages, spreadsheets, and more. The source file can be a local path, a URL, or a base64 string. Carbone tags are PRESERVED, not resolved: converting a template keeps every {d.field} intact, so this is also how you proof a template in another format (DOCX template → PDF, or DOCX → ODT while it stays a template). Use render_document instead when you need data injection ({d.field} tags resolved), translations, or batch generation. Common conversions: DOCX → PDF (file: "report.docx", convertTo: "pdf"; add converter: "I" for the fastest DOCX→PDF path), XLSX → PDF (file: "data.xlsx", convertTo: "pdf"), PPTX → PDF (file: "slides.pptx", convertTo: "pdf", converter: "O" for best fidelity), HTML → PDF (file: "page.html", convertTo: "pdf", converter: "C" for full CSS/JS rendering), DOCX → HTML (file: "doc.docx", convertTo: "html"), XLSX → CSV (file: "sheet.xlsx", convertTo: "csv"), PDF → PNG (file: "doc.pdf", convertTo: "png"), PPTX → PNG (first slide as image), MD → PDF (file: "readme.md", convertTo: "pdf").

  • Convert HTML and CSS to a PDF document using the WeasyPrint rendering engine. Supports every PDF/A archival level, PDF/UA accessibility and the PDF/X print standards. Best for professional documents: invoices, reports, certificates, contracts, and accessible documents. Also produces **fillable PDF forms** — set pdfForms to true. Send a complete HTML document including <html>, <head> with <style>, and <body> tags. Page geometry comes from the document's own CSS @page rule unless paperSize or orientation is set explicitly. Returns a temporary download URL for the generated PDF (valid for 30 minutes). Requires a paid PdfBroker.io plan (Starter or above). EU-first defaults: A4 paper, Portrait orientation when neither the document nor the caller says otherwise.

  • Share text, markdown, code, or HTML as an auto-expiring ctxt.io link. For visual output (styled reports, tables, charts, diagrams) prefer format=html with self-contained HTML: inline CSS and inline SVG render fully; <script> is stripped server-side and JavaScript never runs, so keep it static. Free expiries: 5m, 30m, 1h (default), 8h, 1d — these return the share URL immediately. ttl=30d and the Pro options (name, password) cost $1 one-time: the link is created in a pending state and the result includes a payment_url a human can open in a browser to complete checkout (platforms enrolled for agentic payments receive an acp block instead and can pay programmatically); until payment the link lives 1 day without Pro features. Anyone with the link can read it. The returned delete_token authorizes deletion via delete_context — keep it private.

  • Scrape a URL and return content in your preferred format. Supported output formats: - markdown (default): Clean LLM-ready Markdown text - screenshot: PNG/JPEG image of the page - pdf: PDF document of the page - csv: Table data extracted as CSV - html: Sanitized HTML with scripts/ads removed This tool handles: - JavaScript rendering (SPA, dynamic content) - Anti-bot bypass (Cloudflare Turnstile, Datadome) - DOM cleaning (strips scripts, nav, footer, ads) - HTML-to-Markdown conversion (Mozilla Readability engine) - Automatic retry with escalating wait strategies - Domain cooldown to avoid rate-limiting - Response caching (5 min TTL) Args: url: The URL to scrape (must start with http:// or https://) output: Output format: "markdown" (default), "screenshot", "pdf", "csv", "html" wait_for_selector: Optional CSS selector to wait for before extraction (e.g., ".article-content") timeout_ms: Navigation timeout in milliseconds (default: 20000, max: 120000) block_media: Block images/fonts/video for faster loading (default: true) wait_strategy: Wait strategy: "default", "spa", "heavy", "cloudflare" (auto-detected if omitted) retry: Enable automatic retry on failure (default: true) bypass_cache: Skip cache, force fresh scrape (default: false) javascript: Custom JavaScript to execute after page load (e.g., "window.scrollTo(0, 1000)") Returns: Content in the requested format, or an error message.

  • NEW SITE? STOP — run the BUILD ORDER first (get_account → ask single-file vs multi-page + notification emails → create_data_collection for EVERY repeating section → create_form / create_booking_page → upload_media → THEN deploy). Deploys ONE self-contained HTML file (markup, Tailwind CDN classes, small JS in index.html; optional css/js). Hardcoded list content that belongs in Data is a BROKEN build. After deploy: assign_to_project, configure_chatbot, and ALWAYS hand the user the complete site code in your own interface — deploying alone is not the deliverable. get_guide("workflow") has the full rules. Returns a live URL; reusing a project name redeploys it in-place.

  • Runs YouGame's pre-upload checks on a build folder and returns a verdict: ready, risky (warnings), or broken (the game will not start). Pass every file path in the folder (relative to the folder, forward slashes) and the text of index.html; also pass the text of .html/.css/.js files worth scanning (8 MB of text in total). Fix what it reports and run it again until the verdict is ready, then zip the folder's contents for upload at https://yougame.co/upload.

  • Use this when the user asks to screenshot, capture, or take a picture of a webpage/URL, or to render raw HTML or Markdown to an image or PDF. Do NOT use to get a reusable hosted image URL (use rendex_render_link) or to make a branded multi-format document (use render_artifact). Captures a screenshot or PDF of any webpage, raw HTML, or Markdown. Supports full-page capture, dark mode, ad blocking, custom viewports, CSS/JS injection, cookie/header injection, PDF output, HTML and Markdown rendering, and progressive fallback for heavy sites. Returns partial renders on timeout by default (bestAttempt mode). Costs 1 render credit per call. Cookie/header injection requires Starter+; geo-targeting requires Pro+.

  • Deploy a static site to a live URL — free, no account or API key required. **File content is plain text by default.** Pass HTML/CSS/JS/JSON/SVG/etc. directly in each file's `content` as a regular string. Only set `encoding: "base64"` per-file for binary content (images, fonts) — do not base64-encode text. Returns the live URL. Without a connected account, the response also includes a claim URL (the site expires in 3 days unless claimed) — always show both to the user. To make the site private, pass `password`; always show the password to the user if you set one.
