Use Ad Radar's winning Meta ads inside ChatGPT
Ad Radar's MCP server works in ChatGPT as well as in Claude. Add it once and ChatGPT can search a board of Facebook and Instagram ads that have already passed $50k in estimated spend, read each script, see which hooks win more often and turn a winner into a brief for your product.
- 6 read-only tools
- OAuth sign-in, no key to copy
- Included from $49

How it works
Meta Ad Library research in ChatGPT, with the winners already picked
ChatGPT can call outside tools through MCP, the Model Context Protocol. Ad Radar runs a remote MCP server at https://app.ad-radar.dev/api/mcp, the same one Claude uses. Once it is added, you ask a question in plain English and ChatGPT decides which Ad Radar tool to call, reads what comes back and answers with the brand, the opening line, the estimated spend and the days live, so every claim can be checked.
The board is narrow on purpose. It holds only Meta ads with at least $50k in estimated spend, each tagged on ten dimensions, with its video transcript searchable. On the October 9, 2026 snapshot that was 2,443 ads from 749 brands. The free Meta Ad Library shows every ad and no performance signal for commercial ads; Ad Radar shows the ones brands kept paying for. More on the difference in winning ads library.
Before you start
Which ChatGPT plans can connect it
OpenAI decides who can add a custom MCP server, and it has changed the rules and the menus several times. What its help center said in October 2026:
- Business. Workspace admins and owners add custom MCP servers and can publish them for the workspace. Members then connect with their own Ad Radar account.
- Enterprise and Edu. Admins and owners, plus members an admin has given permission to through role-based access control.
- Pro. Custom MCP servers with read and fetch permissions. That is all Ad Radar needs: every one of its six tools is marked read-only.
- Web only. Custom MCP servers are added on ChatGPT on the web, not in the mobile apps.
If your plan doesn't show the option, you can use the same server in Claude, where custom connectors work on every plan (one custom connector on the Free plan), or use the board in the Ad Radar app. For the current rules, see OpenAI's article Connecting custom MCP servers in ChatGPT.
Setup
Add Ad Radar to ChatGPT
One server address, and a sign-in instead of a key. Menu names below are the ones ChatGPT used in October 2026; if they have moved, look for the place where ChatGPT lets you add a custom MCP server by URL.
ChatGPT on the web
- Open Plugins in ChatGPT (chatgpt.com/plugins), select the + button, then Add custom MCP server. In workspaces still on the older settings, this is under Settings → Apps with Developer mode turned on.
- Name it Ad Radar. Under Connection, enter this URL:
MCP server URL
https://app.ad-radar.dev/api/mcp - For authentication, choose OAuth. Tick the risk warning and select Create as a plugin. ChatGPT lists the six tools it found.
- Sign in to Ad Radar when ChatGPT asks, and approve.
- Start a new chat, type @, pick Ad Radar and ask your question.
Workspaces and the OpenAI API
- Business, Enterprise, Edu: an admin adds the server once and publishes it for the workspace. Each member then connects it with their own Ad Radar sign-in, so everyone sees only their own Ad Radar account.
- Your own code on the OpenAI API: point the remote MCP tool at the same URL and send a personal token as the Bearer token. Create the token in Ad Radar under Settings → API.
- Revoking access: remove the connection in ChatGPT, or revoke it in Ad Radar under Settings → API, where every connected assistant is listed.
Using Claude instead? The setup for claude.ai, Claude Desktop and Claude Code is on the MCP server page.
You need an active Ad Radar plan. The MCP server is included in Membership and Agency, with no add-on.
Examples
What you can ask ChatGPT with Ad Radar connected
Questions from a competitor pass on oral care, with what came back. The numbers are from the October 9, 2026 snapshot.
Find winning oral care ads that have run 90 days or more with at least two variants. Table: brand, opening line, estimated spend, days live.
- list_taxonomy
- search_ads
What comes back
A table of the ads brands have kept feeding. Of the 52 oral care ads on the board, 33 had passed 90 days and 11 ran two or more variants.
Open the LIVFRESH ad that starts "This new toothpaste gel formula" and split the transcript into beats.
- get_ad
What comes back
The 13-line transcript, then a beat map: hook, problem, mechanism, proof, urgency and CTA, each beat quoted so you can check it against the ad.
Which hook patterns and proof levels reach the top tier more often than the board? Flag anything with fewer than 20 ads.
- winning_patterns
What comes back
Tag values ranked against the board baseline of about 10%. Strong proof reached the top tier 16.3% of the time and specific-number openers 12.9%.
Remake the LIVFRESH ad for my toothpaste tablets: fluoride-free, 60-day jar, $24. UGC, 30 seconds.
- get_swipe_prompt
What comes back
A structure map of the donor ad and a first draft for your product at about the same length. You still replace any claim you can't back for your own product.
More questions that work well:
- "What is this brand repeating across its winning Meta ads this month?"
- "Show me problem-aware UGC skincare ads that open with a number."
- "Which landing page types do the winning supplement ads send people to?"
- "List the valid niches and hook patterns, then find the top founder-led ads in pet."

The valid values of the ten tag dimensions, so ChatGPT filters with exact words instead of guessing. The full description of each tool is on the MCP server page, and how the tags are defined in the methodology.
Claude or ChatGPT
Same server, two assistants
The data, the tools and the sign-in are the same. What differs is how each assistant lets you add a server.
| Topic | ChatGPT | Claude |
|---|---|---|
| Where you add it | Plugins, Add custom MCP server (web) | Connectors, Add custom connector (claude.ai and Desktop), or one command in Claude Code |
| Plans | Business, Enterprise/Edu; Pro with read and fetch permissions (October 2026) | Free (one custom connector), Pro, Max, Team, Enterprise |
| Sign-in | OAuth with your Ad Radar account | OAuth with your Ad Radar account |
| Server URL | https://app.ad-radar.dev/api/mcp | https://app.ad-radar.dev/api/mcp |
| Setup guide | This page | MCP server page |
Limits
What it won't do
- Meta only. The board covers Facebook and Instagram ads. TikTok is on the roadmap, Google and YouTube ads are not on it.
- It never touches your ad account. The tools read the Ad Radar board of competitor ads. They can't see your campaigns, change a budget or launch an ad.
- Spend is estimated. Every figure is modeled on public engagement data from the Meta Ad Library. Use it to rank ads against each other, not as a competitor's invoice.
- Winners only. Ads under $50k in estimated spend are not on the board. To keep any other ad, save it from the Meta Ad Library with the Chrome extension.
- You still sign off. Open a few ads yourself before a brief goes out, and check that the lines ChatGPT quoted match the transcript.
FAQ
Questions
Can I use Ad Radar inside ChatGPT?
Yes. Add Ad Radar's MCP server, https://app.ad-radar.dev/api/mcp, to ChatGPT as a custom MCP server, sign in to Ad Radar when ChatGPT asks, and mention it with @ in a chat. ChatGPT can then search the board of winning Meta ads, read transcripts and write briefs from them.
Which ChatGPT plans can add a custom MCP server?
OpenAI decides this and changes it often. In October 2026 its help center listed custom MCP servers for ChatGPT Business and Enterprise/Edu on the web, with Pro accounts able to connect servers with read and fetch permissions. All six Ad Radar tools are read-only. If your plan doesn't show the option, use Ad Radar in Claude, which supports custom connectors on every plan, or in the web app.
Is Ad Radar listed in the ChatGPT app directory?
Not yet. Until it is, add it by URL as a custom MCP server. The server, the tools and the sign-in are the same either way.
Do I need an API key to connect ChatGPT?
No. Choose OAuth when you add the server: you sign in to Ad Radar and approve the connection. A personal token from Settings → API is only needed for clients that send a fixed Bearer token, such as your own code on the OpenAI API.
Can ChatGPT change my Meta ad account through Ad Radar?
No. The six tools are read-only and read the Ad Radar board of competitor ads. Ad Radar doesn't connect to your ad account, so nothing in your campaigns can be seen or changed through it.
Does the ChatGPT connection cost extra?
No. The MCP server is included in every Ad Radar plan: Membership at $49 every 4 weeks (launch price, list $99) and Agency at $199 every 4 weeks. You need an active plan to connect.
Is the spend data exact?
No. Every spend figure is an estimate modeled on public engagement data from the Meta Ad Library, tracked over time. Use it to rank ads against each other, not as a competitor's real budget, and ask ChatGPT to label it as estimated.
