Add MCP Ads to ChatGPT as a custom connector
ChatGPT connects to MCP Ads as a custom connector in Developer mode. Paste the URL once, sign in through the browser window ChatGPT opens, then switch the connector on in a chat.
Before you ask: in ChatGPT open Settings → Plugins → Browse plugins and turn on Developer mode. Then Settings → Connectors → Add custom connector, name it MCP Ads, paste https://mcp-ads.com/mcp-slim and sign in. In a new chat, open the tools menu and switch MCP Ads on. In a Business workspace, an admin may have to enable Developer mode first.
first message in ChatGPT
Use MCP Ads for every question about my ads, analytics or SEO.
Which ad accounts can you see through it?
Then give me an overview of the first Google Ads account and one thing to fix today.

The MCP Ads plugin is in review for the ChatGPT plugin directory. Until it is listed, the custom connector in Developer mode is the way in. A Custom GPT cannot use connectors; for that, MCP Ads publishes an OpenAPI Action.
2AskLive data
Ask anything about your ad accounts
Once connected, ChatGPT pulls live numbers from every account you linked. Start with questions like these:
Where did my Google Ads budget go last month?
Checked Google Ads for the last 30 days. Two campaigns took 70% of spend; one of them converts at half the account average, and 14 search terms spent $1,120 with no conversions. Want me to list them as negative keywords?

What to ask ChatGPT once it is connected
Google Ads
Wasted spend audit
“Find search terms with over $50 spend and zero conversions in the last 30 days and group them into negative keyword themes.”
Meta Ads
Creative fatigue check
“Which Meta ads have falling CTR and rising frequency this week? Suggest three new angles from what competitors run in the Ad Library.”
Cross-channel
Cost per lead, side by side
“Compare cost per lead across Google Ads, Meta and LinkedIn for the last completed month, and say where the next $1,000 should go.”
GA4
Where conversions come from
“From GA4, show conversions by source and landing page for the last 28 days, and which paid source is under-reported.”
Search Console
Page-two keywords
“Show queries where we rank 5 to 15 with over 500 impressions, and which page to improve for each.”
Competitors
What competitors run
“Pull the active Meta and Google ads of my top three competitors and summarise their offers and angles.”
Campaign build
A paused campaign to review
“Build a Google Search campaign for my main service from my site and best keywords, paused, and show me everything before it goes live.”
Reporting
Weekly client report
“Write last week's report across every connected ad account: spend, conversions, CPA, and the one campaign that needs attention.”
Why live data beats pasted exports
Without a connector, ChatGPT only sees the CSV you paste, a few days old and missing the columns you forgot. With MCP Ads it reads the accounts directly at the moment you ask, across every platform, so the comparison is real and current.
What it will not do without you
Reads are unrestricted. Writes are proposed first: a campaign is created paused, and a budget or status change happens only when you ask for it by name. Workspace roles in MCP Ads decide who can change what.
Connectors are per chat
ChatGPT keeps connectors off by default in each conversation. If the tools never appear, open the tools menu in that chat and switch MCP Ads on.
Choose the right sign-in
The browser sign-in decides which ad accounts ChatGPT sees. Use the Google or Facebook identity that already has access to them; picking another one is the most common reason an account is missing.
The honest limits
Developer mode is needed until the plugin is listed in the ChatGPT directory, and some Business workspaces have it switched off by an admin. A Custom GPT cannot use connectors at all and uses the OpenAPI Action instead.
Questions
Which URL do I add in ChatGPT?
https://mcp-ads.com/mcp-slim. It exposes one tool per platform that takes an action name, so it loads fast and ChatGPT discovers the rest as it needs them.
Do I need an API key?
No. The connector signs in through the browser (OAuth). There is no key to copy or paste into ChatGPT.
Which ChatGPT plans can use it?
Any plan where Developer mode and custom connectors are available to you. In a Business or Enterprise workspace, an admin may need to allow them.
Can ChatGPT change my campaigns?
Only when you ask, and only on accounts you connected. New campaigns are created paused, and you see the change before it goes live.
Which platforms does it cover?
Google Ads, Meta Ads, Microsoft Advertising, LinkedIn Ads, TikTok Ads, Snapchat Ads, X Ads, GA4, Search Console, Google Tag Manager, Merchant Center, WordPress and organic posting to Facebook, Instagram, LinkedIn, TikTok and Threads.
