WebCake Landing MCP
English Β· TiαΊΏng Viα»t

Describe a landing page in plain words β your AI builds it, checks it, and ships it straight to WebCake.
β If this saves you an afternoon of dragging boxes, give it a star β it's a one-dev project and every star keeps it alive.
"Build a landing page for my coffee shop β a hero with a sign-up button, a 3-feature section, and a lead form. Save it to my workspace."
β¦and a real, editable WebCake page appears in your account. No dragging boxes, no learning the schema, no hand-writing JSON.
π§© How it works
This server is the bridge between your AI assistant and WebCake. The AI never guesses what a WebCake
page looks like β it asks this MCP, which knows the entire element model, validates the result, and saves it for you.

- You ask in plain language β goal, brand, sections, CTA, form fields.
- The AI learns the model from the MCP: the element catalog, the absolute-positioning canvas, the event vocabulary β so it builds a real WebCake page, not a guess.
- It assembles + validates the full
{ page, popup, settings, options } JSON. validate_page catches off-canvas boxes, dangling CTAs, and missing form fields before anything is saved.
- It persists to your WebCake account β dry-run preview first, then for real.
- You get an editor link β open it, tweak, publish. The AI did the heavy lifting.
Why it's reliable
| |
|---|
| π Knows the real model | Serves WebCake's actual element catalog (40+ types β hero, form, countdown, gallery, product listβ¦), each with its exact specials and AI hints, drawn straight from the editor's renderers. |
| β
Validates before saving | Structural + semantic checks (unique ids, on-canvas layout, working CTAs, unique form fields) so the page isn't broken when it lands. |
| π‘οΈ Safe by default | Every write is dry-run first (preview the request, token masked) β nothing touches your account until you confirm. |
| βοΈ Edits surgically | Ask for one change ("make the CTA green") and it edits only that element β every other id, coordinate, and block stays exactly as it was. |
π‘ Lead-gen, events, invitations, app promos β or selling COD/online? It speaks WebCake's commerce model too (product lists, variations, cart).
β¨ What you can build
One sentence to your AI β a finished, editable WebCake page. A taste of what people ship with it:
| Just say⦠|
|---|
| π§² Lead-gen landing | "A SaaS waitlist page β hero, 3 benefits, an email-capture form." |
| π COD / online store | "A one-product page for my skincare serum β gallery, price, variations, an order form with cart." |
| ποΈ Event / webinar | "A registration page for Saturday's webinar β countdown, agenda, sign-up form." |
| π Invitation | "A wedding invite β names, date, a map, an RSVP form." |
| π± App promo | "A page for my fitness app β phone mockups, feature list, App Store + Google Play buttons." |
| β‘ Flash sale | "A flash-sale page β big countdown, discounted product grid, a sticky Buy button." |
| π Link-in-bio | "A link-in-bio for my creator profile β avatar, short bio, 5 link buttons, socials." |
| π Product launch | "A launch page for v2 β hero, what's-new list, an early-access form." |
β¦then "make the CTA green" or "add a 4th feature" and it edits only that block β every other id and coordinate stays exactly where it was.
π€ Works in Claude Desktop, Claude Code, Cursor, Windsurf, Augment, Codex, Antigravity, Gemini CLI, Cline, Kiro, OpenCode, or any MCP-capable client β and the reference + generation tools need zero setup, so you can try it before ever pasting a token.
Under the hood
MCP (Model Context Protocol) server that teaches AI agents how to build a complete
WebCake landing-page source JSON from a requirement β and persist it to a WebCake backend.
It exposes the element catalog, per-element usage hints + specials, the full page JSON Schema,
valid element/page skeletons, a page validator, and tools to create or edit pages on the backend.
The AI agent produces the full { page, popup, settings, options, cartConfigs } JSON; create_page
persists it and auto-publishes (build + publish_html) so the preview renders immediately (the edit
tools save source-only β re-publish via publish_page after edits).
| Method | Best for | Auth |
|---|
| npx (local) β runs on your machine | Personal daily use, full control | browser login, a JWT, or none (reference tools) |
| Hosted URL β use our live server, nothing to install | No Node.js, teams, the claude.ai dialog | your personal ?jwt= link / x-webcake-jwt header |
The reference + generation tools (get_generation_guide, list_elements, validate_page, β¦) and the ingest tools (ingest_html, ingest_url β turn an existing HTML or URL into a layout anchor so the AI can recreate or adapt it) work with zero config; only the persistence tools (create_page, update_page, add_section, patch_page, publish_page, list_pages, find_pages, get_page, list_organizations) need a token. Credentials resolve in order: per-request header β env var β saved auth.json (login).
π Get connected β the 2 main ways
Pick one. Both hand your AI tool (Claude, Cursor, β¦) the full Webcake landing toolkit. No coding.
β npx β runs on your machine (recommended for personal use)
Zero install, always the latest version, needs Node.js 18+. One line grabs your token and writes the IDE config:
npx -y webcake-landing-mcp install
npx -y webcake-landing-mcp install --ide all --env prod --jwt <your-jwt>
npx -y webcake-landing-mcp uninstall
It writes a webcake-landing entry into the right config file for each target: claude-desktop,
claude-code, cursor, windsurf, augment (VS Code), codex, antigravity, gemini (Gemini CLI),
cline, kiro, opencode, or all. Flags: --ide, --env, --jwt, --org-id,
--api-base/--app-base, --npx/--local, -y β see install --help.
Just want to run the server (configure by hand later)? npx -y webcake-landing-mcp
π οΈ Hand-written per-IDE config, shell-script installers (install.sh/install.ps1), or a cloned
local build β docs/manual-install.md.
β‘ Remote URL β¦/mcp?jwt= β hosted, nothing to install
The server is already live at https://mcp.toolvn.io.vn/mcp β no Node.js, no machine to keep awake.
Grab your personal link (your token is baked in) and paste it into your client's Add custom connector / config:
https://mcp.toolvn.io.vn/mcp?jwt=<YOUR_TOKEN>
Two ways to get the link:
Optional extras: &env=prod, &org_id=β¦, &api_base=β¦. Hand each teammate a link with their own jwt β
per-user, no OAuth. Clients that support headers should send the token as x-webcake-jwt instead of
putting it in the URL β the full header β env mapping is in docs/configuration.md.
β
Best for: no Node.js, team/shared use, the claude.ai connector dialog (URL-only, no headers).
β οΈ The link contains your personal token β treat it like a password, always use HTTPS.
βοΈ Configuration
The quick version β only the persistence tools need any of this:
npx -y webcake-landing-mcp login
β¦or set WEBCAKE_ENV (local | staging | prod β fills in all base URLs) + WEBCAKE_JWT.
For publish_page to actually put a page live, a build host is needed (it renders the
app/app_css that the live publish_html route requires):
prod preset auto-configures https://build.webcake.io β no extra setup (the preset applies when the env resolves to prod: WEBCAKE_ENV=prod, --env prod, or x-webcake-env: prod).
- For staging/local, set
WEBCAKE_BUILD_BASE=<url> or send the x-webcake-build-base header per request.
- Without it,
publish_page falls back to a legacy source-only save with rendered:false, live:false + a warning β nothing goes live.
- A page is only permanently live with a
custom_domain; without one the returned /preview/<page_id> link expires ~10 minutes after the publish.
Everything else β the full env-var table, environment presets, per-request headers for the hosted
server, the login browser flow (+ backend contract), and how to grab a JWT by hand β lives in
docs/configuration.md.

| Media | search_images (real Pexels stock photos) Β· get_icon_svg (Material Symbols / Font Awesome icon names β inline SVG via Iconify) Β· upload_images (re-host external images, data: URIs, or local file paths from the user's machine β files into your media collection when Webcake creds and an org are available; the org is required and must match the page's, so settle it up front β 1 org auto-selects, 2+ with none chosen returns organization_required + the list; no JWT β the public CDN) Β· render_preview (screenshot a page/URL so the model can see + compare it) | nothing |
| Ingest | ingest_html Β· ingest_url (recreate an existing page) | nothing |
| Persistence | list_organizations Β· create_page Β· list_pages Β· find_pages Β· get_page Β· update_page Β· add_section Β· patch_page Β· publish_page | WEBCAKE_API_BASE + WEBCAKE_JWT |
Every write defaults to dry_run=true β it previews the exact request (token masked) and only
touches your account when you re-run with dry_run=false.
Suggested prompt
Build me a WebCake landing page for <brand/offer>. Use the webcake-landing MCP:
call get_generation_guide, new_page_skeleton, then get_element for each element type you use,
assemble the { page, popup, settings, options } JSON, validate_page until zero errors,
then create_page (dry-run first).
β Like the idea? Drop a star
This is a solo, open-source project β every β genuinely keeps it moving and helps other builders discover it.
