How to Connect Reddit Ads to ChatGPT

One thing to keep apart first: this guide is about managing your own Reddit Ads account from ChatGPT. It has nothing to do with ads shown inside ChatGPT.

Custom MCP servers are added through ChatGPT's Developer mode. OpenAI's Developer mode guide lists it as available to Pro, Plus, Business, Enterprise, and Education accounts, on the web only, and describes it as full MCP support for read and write tools, with write actions asking for your confirmation by default.

OpenAI's help centre is more cautious. Its MCP apps article says write actions are for Business, Enterprise, and Edu, and that Pro accounts connect custom servers with read and fetch tools. The two pages do not agree, so on Plus and Pro treat reporting as the safe expectation and test one small change before you rely on more.

From a new AdPlug account to ChatGPT answering questions about your Reddit Ads data takes about five minutes. You'll need a Reddit account that's a member of your Reddit Ads business, with access to the ad accounts you want ChatGPT to work on.

1. 1

   Create your AdPlug account

   Go to adplug.app/signup, sign in with Google or email, and follow the short onboarding. It ends on your AdPlug dashboard.

   

2. 2

   Connect Reddit Ads to AdPlug

   On the dashboard, click Connect Reddit Ads (or open the Connections page). AdPlug sends you to Reddit's own sign-in. Use the Reddit account that's a member of your Reddit Ads business and has access to the ad accounts you want ChatGPT to work on.

   

   Reddit then asks you to let AdPlug:

   • read advertising data through your account
   • edit advertising data on your behalf
   • post conversion events through your account
   • keep this access until you revoke it

   Click Allow and you're back in AdPlug with Reddit Ads connected. Every ad account your Reddit account can reach comes through the one connection.

   No developer app needed

   AdPlug uses its own access to Reddit's Ads API, so there's nothing to set up in Reddit's developer portal and no keys to copy.

3. 3

   Turn on Developer mode in ChatGPT

   In ChatGPT on the web, open Settings. Developer mode sits in one of two places, depending on which layout your account has: Apps → Advanced settings (shown below), or Security and login on the newer layout, where Apps has become Plugins. Switch it on. The Elevated risk label belongs to Developer mode itself: it lets you add connectors OpenAI has not verified. The toggle's own note also says Memory is disabled while it is on.

   

   

   If your menus look different

   OpenAI is moving Apps to Plugins and the labels are changing with it. Its Developer mode guide has the current ones.

4. 4

   Add AdPlug to ChatGPT

   Go back to Settings → Apps and click Create app. On the newer layout, open Plugins and use the plus button. Either way, fill in:

   • Name: AdPlug - Reddit Ads
   • MCP Server URL: the address below
   • Authentication: leave as OAuth
   • Tick I understand and want to continue, then click Create

   On Business, Enterprise, and Edu workspaces the form also has a Scan Tools button. Click it, approve the AdPlug sign-in when it opens, and let the scan finish before you click Create.

   Copy

   

   ChatGPT then opens AdPlug's sign-in. Use the same email as your AdPlug account and click Approve.

   

   The app now appears under Enabled apps with a Dev label. If you would rather copy than type, your AdPlug dashboard shows the same name and address with copy buttons.

   

5. 5

   Test the connection

   Start a new chat, open the + menu in the composer, and select the AdPlug app (on some accounts it sits under Developer mode in that menu). Then ask:

   “Show my Reddit ad accounts.”

   ChatGPT calls the reddit_ads_list_accounts tool and returns the Reddit Ads businesses and ad accounts your Reddit login can reach, with each account's currency and approval state. If your accounts are listed, the connection works end to end.

   

These work as soon as the account is connected. Swap in your own site, budget, and communities.

AdPlug gives ChatGPT two tools for campaign changes. A preview tool returns the exact change (with a before and after for edits, and a warning when a budget or bid at least doubles) without sending any change to Reddit. An execute tool applies it. Ask for the preview first. ChatGPT treats the execute tool as a write action and asks you to confirm before running it.

ChatGPT also has a permission setting for connected apps, with options such as Always ask, Allow read actions, and Allow low-risk actions. For an ad account, keep it on Always ask or Allow read actions, so every change waits for you.

New campaigns, ad groups, and ads are created paused unless you ask otherwise, so nothing spends until you switch it on. The free plan is view only; creating and editing campaigns needs a paid AdPlug plan. Report calls and executed changes are recorded in your AdPlug Usage and Audit Log.
