Look for Connectors, Integrations, MCP servers or Plugins in your client, and choose to add a remote server.
Server address
https://www.adstar.ai/mcp

"servers": {
"adstar": {
"type": "http",
"url": "https://www.adstar.ai/mcp"
}
}
}
03.Sign in on first use
Your client opens AdStar's sign-in page in a browser; sign in with Google or Microsoft and click Allow. The callback has to be an https or localhost address, which is what current clients use.
Try this first
With AdStar, show my account and list my products.
Building a client? The server follows the 2026-07-28 revision of the protocol: stateless streamable HTTP, OAuth 2.1 with PKCE and dynamic registration, discovery at /.well-known/oauth-protected-resource/mcp. Clients on the 2025-11-25 revision are served too.
No API keys. You sign in on adstar.ai with the Google or Microsoft account you already use, and you can disconnect at any time from Settings → Account → Connected apps.
From a message to a finished ad
The assistant drives the same pipeline the website uses. You stay in the chat; AdStar does the production.
Point it at a product
Paste a product page and AdStar reads the name, description, benefits and photos, with the brand from the site. No page? Describe the product and add photos from the chat.
Agree to the quote
Before anything is spent, the assistant quotes the ad and tells you the price and your balance. Nothing starts until you say yes.
Watch it being made
Script, scenes, voiceover, music, captions and the branded end card, assembled into a complete video. In ChatGPT and Claude an AdStar card shows the progress and plays the result.
Open it in AdStar when you want more
Every ad lands in your account. Open the editor to change a scene, resize, translate or swap the end card, exactly as with ads made on the site.
Import yourstore.com/products/night-serum and make a 9:16 UGC ad in English.

Yes, go ahead.

Started. The card below updates itself; it takes a few minutes.
Just ask
Talk to AdStar the way you talk to your assistant. Every ad type, format and language from the site is one sentence away.
Import https://yourstore.com/night-serum and make a 9:16 UGC ad in English.
One message runs the whole path: the product is read from its page, the quote comes back with the price and your balance, and the ad starts once you agree.
Ads

Your account, your rules
An ad costs real money, so the server, not the model, enforces what may be spent and when.
Same account, same credits
Ads made from a chat land in your AdStar account next to the ones made on the site, and cost the same. Reading, importing and quoting are free.
Promo or Service ad250 credits

Recipe runquoted per run
Nothing is spent without a quote
The assistant must quote first and tell you the price and your balance. The call that starts an ad carries a spending cap at the quoted price and a one-time key: a retry returns the same ad instead of starting another, and a price above the cap is refused with nothing charged.
If an ad fails, its credits come back.
Connect and disconnect yourself
Sign-in is OAuth on adstar.ai: no API key to create or leak, and the assistant never sees your password. Each connected app is listed under Settings → Account → Connected apps; Disconnect cuts it off on its next call.
Text the assistant reads from imported pages is treated as content, never as instructions.
FAQ
The Model Context Protocol is an open standard that lets an AI assistant use outside tools. AdStar runs an MCP server at https://www.adstar.ai/mcp. Add that address to ChatGPT, Claude or any other MCP client and the assistant can import your products, quote and start ads, and follow them to the finished video, all on your AdStar account.
No. You add one address and sign in on adstar.ai with the Google or Microsoft account you already use. The assistant receives a token for your account, never your password, and you can revoke it at any time from Settings → Account → Connected apps.
Any account can connect and browse for free. Making an ad takes credits, as on the site: 250 for a Promo or Service ad, 300 for UGC. The 7-day trial comes with 250 credits, enough for a first ad; after that a subscription or a credit pack covers the rest, managed on the site under Settings → Plan.
Any client that supports remote MCP servers with OAuth sign-in: ChatGPT, Claude on the web, desktop and mobile, Claude Code, Codex, Cursor, VS Code and others. Claude's free plan allows one custom connector; whether ChatGPT lets you add a custom server depends on your plan and workspace policy. The sign-in itself is the same everywhere.
Several minutes, usually under ten. In ChatGPT and Claude an AdStar card appears in the chat and updates itself until the video is ready. Text-only clients such as Claude Code or Codex wait on your behalf and report the links. You can close the chat: the ad lands in your AdStar account either way.
The rules are built into the server, not left to the model. An ad must be quoted first, and the assistant is told to show you the price and ask. The call that starts an ad carries a spending cap at the quoted price and a one-time key, so a retry returns the same ad instead of starting another, and a price above the cap is refused with nothing charged. Most clients also ask you before running a tool that is not read-only.
Yes. In ChatGPT and Claude the assistant can open an upload card where you pick or drop files, and they go straight onto the product. Any client can add photos from web addresses, and a script can PUT a file to a signed address the server hands out.
In Claude, open the connector under Settings → Connectors and choose Refresh tools list: Claude keeps the list from the day you added the connector. In Claude Code and Codex, start a new session after adding the server. In ChatGPT, open the plugin and choose Refresh. If several MCP servers are connected, say "with AdStar" in your prompt so the request goes to the right one.
On the site, open Settings → Account → Connected apps and click Disconnect. The app loses access on its next call. Then remove the connector in the client as well, so it stops asking you to sign in again.
Not yet. A listing in the ChatGPT plugin directory is being prepared, and Anthropic's connector directory does not list AI media generators as its policy stands. The custom connector route on this page works everywhere today, and the address will not change.
Write to support@adstar.ai. For a problem with a connection, say which client you use and roughly when it happened; every sign-in is logged on our side, so that is enough to find it.
