WebMCP
Your agent can use Advibly the way you do.
Advibly puts its workspace on document.modelContext as 22 tools, offered as they become usable: a handful before you sign in, the whole workspace once you have. An agent running inside your browser can read your brand, draft into the composer and generate on-brand ads as you, on the session this tab already holds. No API key, no OAuth round trip, and nothing it does happens off-screen.
Live on this page
These are the real tools, right now.
The list below is read straight out of this tab's modelContext, not a hand-written table. Pick one and call it exactly the way an agent would.
Why in the page
The agent is a second pair of hands, not a second account.
No second identity
The tools run on the Clerk session and the live Convex subscription the page already holds. There is no token to mint, no consent screen, no per-agent API key - the agent is simply you, in your own tab.
One shared screen
A tool call is not a silent API request. The composer fills in with the prompt the agent wrote, the brand switches in the sidebar, and the render appears on the wall while you watch. You always know what it just did.
Approval before spend
Generations cost credits, so every one of them stops on an approval card showing the exact prompt, settings and price before anything is charged. Decline is a first-class answer the agent is told to respect.
Getting there
Three steps, no install.
- 01
Open Advibly in an agentic browser
ChatGPT's in-app browser ships WebMCP. In desktop Chrome, enable chrome://flags/#enable-webmcp-testing and restart. Everywhere else this page installs the WebMCP polyfill, so extension-based agents still find the tools.
- 02
Sign in
Signed out, an agent gets the public tools: what Advibly is, what it costs, which skills exist. Signed in with a brand onboarded, the whole workspace lights up.
- 03
Ask for what you want
"Look at my brand and make me three scroll-stopping image ads for the new launch, 9:16." The agent reads the brand, writes the prompts into the composer, and asks you to approve the spend.
The surface
Every tool, and what it does to your screen.
Available to everyone
Registered on every page, signed in or not. An agent can answer questions about Advibly from the page itself rather than from a scrape.
about_adviblyread-onlyWhat Advibly is, what it makes, who it is for.
get_advibly_overviewread-onlyThe full markdown site overview (llms.txt).

open_signupTake the human to sign-up.
Once you are signed in
The agent reads the same workspace the human is looking at, and moves them around it. No API key, no OAuth handshake: it runs on the session the tab already holds.
get_page_contextread-onlyThe current route, brand, composer state, selected product and credit balance.
list_brandsread-onlyEvery brand on the account, and which is selected.
get_brandread-onlyA brand's identity: description, colours, tone, logo, kit.

suggest_ideasread-onlyStarting points for this brand, each with a written prompt.
navigateOpen another page of the app.
set_composer_modeSwitch the composer between image, video, carousel, actor.
Making things
Every one of these writes into the composer on screen first, so the human watches the request being assembled, approves the spend on a card that shows the exact prompt, and then watches the result land on their wall.
draft_in_composerWrite a prompt into the composer WITHOUT firing it - the human edits and presses Generate.
generate_imageneeds approvalRender an on-brand image ad, product visual or social graphic.
generate_videoneeds approvalRender a short video ad or lifestyle clip.
plan_carouselPlan a multi-slide deck and open the slide-by-slide review modal. Free until the human confirms.
Try saying
Things that work on the first try.
- “What is this site, and what would it cost me?”
- “Read my brand and suggest five things worth making this week.”
- “Draft an image prompt for a founder-holding-the-product shot, but do not generate it yet - I want to edit it.”
- “Make two 9:16 image ads for my best-selling product, then tell me when they land.”
- “Plan an Instagram carousel that explains why our returns policy is different.”
Outside the browser
WebMCP is one of three ways an agent reaches Advibly, and they share the same backend. A hosted MCP server at advibly.com/mcp (OAuth 2.1, dynamic client registration) covers agents that are not in a browser, and npx advibly turns the same tools into terminal subcommands. Work started in one shows up in the others, because they are all writing to the same library.
