Set Up Claude
For Meta? Now Do This

I used to work in advertising at Meta. Here’s what the Meta ads connector in Claude is actually good at, the 5 prompts I run on my own accounts and how to stay in control of your spend.

Meta built an official ads connector that lets Claude read and manage your ad account. It’s still in beta, and not every ad account has access yet. (Meta’s docs)

  1. Add it. In Claude, go to Customize (called Plugins on newer accounts), then Connectors. Click + Add, then Add custom connector, and paste https://mcp.facebook.com/ads.
  2. Sign in. Click Connect and log in with the Facebook account that manages your ads.
  3. Turn it on. In a new chat, click +, then Connectors, and switch it on. The Free plan allows one custom connector. On Team and Enterprise plans, an owner has to add it first.
What It’s Good At

01

Reporting in plain English

Ask for a breakdown of your last 30 days by campaign with spend, cost per purchase, ROAS and conversions. Claude pulls it live from your account in seconds. No more ten tabs in Ads Manager.

02

Spotting what looks off

This is where I think most people will get the most value. Ask "what looks off in my account this week" and Claude goes through your numbers for the things you’d miss: CPM spikes out of nowhere, frequency creeping up (the same people seeing your ad too often) or conversions quietly dropping. Meta also built an anomaly check into the connector, and prompt 2 tells Claude to run it.

03

Building campaigns, paused

It can create campaigns, ad sets and ads. Meta makes every new one start paused, and Claude asks you before turning anything on. Edits to ads that are already running are different: those change live ads, so approve them carefully.

The 5 Prompts I’m Running

Turn the connector on, paste a prompt and replace the [brackets] with your numbers.

1. Morning Brief
Using my Meta ad account, show me the last 7 days for every active campaign: spend, revenue, ROAS, cost per purchase, frequency and purchases. Then: 1. Flag any ad with frequency over 3.5, or cost per purchase more than 2x my target of [$XX]. 2. Show me the top 3 ads ready to scale: running 3+ days, ROAS above [3.0], frequency under 2.5. 3. Tell me one thing that looks off that I should check today. Keep it short. Don't change anything. Just give me the read.
2. Anomaly Scan
Look at my Meta ad account for the last 14 days and tell me what looks off. Start by running the connector's anomaly check, then also look for: - CPM more than 25% above my 30-day average - Any ad with frequency above 4 - Ads that were strong but dropped more than 30% in ROAS week over week - Click-through rate falling while CPM rises on the same audience - Campaigns where spend went up but purchases went down For each one, tell me what it is, when it started and the most likely cause. Don't change anything.
3. Creative Fatigue Check
Pull every active ad in my Meta account that has been running 21+ days. For each one, show me how the click-through rate, frequency and cost per purchase have changed over the last 21 days, and whether it's still under my [$XX] target. Sort them into three groups: - Refresh now: CTR falling, frequency over 3.5 and cost per purchase above target - Watch: one warning sign but still profitable - Keep running: still healthy
4. Paused Test Campaign
Build me a new test campaign in my Meta ad account and leave everything paused: - Objective: Sales, optimized for purchases - Daily budget: [$50] - Audience: [Advantage+ audience, excluding my past purchasers] - 1 ad set, because I'm testing creative, not audiences - Name it: [2026-11_Test_CreativeName] I'll add [3] ads myself. Before you create anything, show me the plan. After, show me what you built and confirm it's paused. Do not turn it on.
5. Budget Reallocation
Look at the last 14 days of spend across all my active Meta campaigns. Then: 1. Which campaigns are getting more money than their results justify? 2. Which are doing well but running out of budget? 3. Recommend how to move budget in dollars: where to take it from, where to add it and how much. 4. What would have to be true for this to be the wrong move? Put it in a table. Don't change anything. I'll make the changes myself.

Want the morning brief every day without asking? On a paid plan, tell Claude to make prompt 1 a scheduled task every weekday at 8am.

Before You Give It Write Access

01

Start read-only

For your first few days, only let Claude look. In Customize (or Plugins), then Connectors, click the Meta connector and set every tool that creates, edits or turns on ads to Needs approval or Blocked. Reporting still works. (How tool permissions work)

02

Set an account spending limit

In Meta, go to Billing & payments, then Payment settings, and set an Account spending limit. It’s a total cap: when you hit it, your ads pause until you raise or reset it. Set it low, because you can always raise it. (Meta’s instructions)

My Honest Take

It doesn’t replace the judgment of a good media buyer. But for the daily checking that used to eat 30 minutes of my morning, it’s a real win. Want an agent that does all of this every day? Here’s my Meta Media Buyer Agent.
