OpenAI Ads (ChatGPT ads) in Claude and ChatGPT: read and manage every ad account with one connector

Fezola connects your OpenAI Ads (ChatGPT ads) accounts to Claude and ChatGPT: you paste each account's API key into Fezola once, add Fezola as a single connector, and the assistant can read and manage every ad account. Changes are simulated first, and new campaigns start paused. Nothing to install. ChatGPT accepts custom MCP servers on Business and Enterprise/Edu plans (Pro read-only), so Claude is the easiest way in. The short version is on the OpenAI Ads connector page.

What the assistant can do

Read, from Fezola's tools:

• openai_ads_list_accounts: the accounts you connected, with name, status (an account under review does not serve), currency and time zone.
• openai_ads_campaigns, openai_ads_ad_groups, openai_ads_ads: campaigns, ad groups and ads of an account.
• openai_ads_insights: daily spend, impressions and clicks per campaign, ad group or ad, over up to 90 days.
• openai_ads_conversions_insights: the conversions OpenAI Ads actually counted and attributed.
• openai_ads_conversion_event_settings, openai_ads_pixels and openai_ads_geo_lookup: conversion events, pixels and target locations.

Change:

• openai_ads_create_campaign: create a campaign. The plan lists what cannot be changed after creation: the budget is a lifetime spend limit, not a daily budget, and the bidding type is fixed.
• openai_ads_update_campaign: change the name, description, end time, linked conversion events or lifetime budget.
• openai_ads_set_campaign_status: set a campaign to active, paused or archived. Archiving cannot be undone, and OpenAI Ads has no deletion.

Ad groups and ads can be read through Fezola. Creating or editing them is not offered yet.

What you can ask

• "Compare spend, impressions and clicks of my campaigns over the last 14 days, account by account."
• "Which campaigns got counted conversions this week?"
• "Create a paused campaign called Spring launch with a 500 lifetime budget, targeting Lyon. Show me the plan first."
• "Pause the campaign with the highest spend and no conversions."

Safeguards, and their limits

• Simulate first. Each writing tool takes dryRun, true by default: it returns the plan or the changes and applies nothing. The irreversible field of a campaign plan lists the choices that cannot be changed later, and warnings lists what is missing, such as conversion events.
• New campaigns start paused unless you ask for active, because active campaigns spend real money. The tool description tells the assistant to do so.
• Marked destructive. The writing tools carry the MCP destructive hint, so assistants that ask for approval before such actions will ask. Keep those approvals on.
• Encrypted keys. Each Advertiser API key is stored encrypted, with only the last four characters kept for display.
• No spending cap on Fezola's side. If you let an assistant activate a campaign or raise a budget, OpenAI bills what it spends. Start with the simulation.

Setup

1. Create a free Fezola account. In Sources, Add source, OpenAI Ads, paste the Advertiser API key of an ad account. You create it on the Settings page of OpenAI's Ads Manager, and one key belongs to one ad account. Repeat for each account.
2. Add Fezola to Claude with https://api.fezola.com/mcp: see how to add a custom connector to Claude.
3. Ask. You can also tell Claude "connect my OpenAI Ads" once Fezola is added.

Ads Manager availability depends on OpenAI and on your market: check OpenAI's Ads documentation before you connect.

One connector for the rest of your advertising

The same Fezola connector also reads and manages Google Ads accounts, alongside mail, Google Chat, Telegram, Google Calendar and Notion. Connect everything once in Fezola, then add only Fezola to each Claude or ChatGPT account.

What's next

Fezola's direction is simple: if a tool only has an API, we build the connector. Others are being prepared and have no release date.

Three ad platforms, one connector

Fezola also reads and manages Google Ads and Microsoft Advertising accounts. Google Ads, Microsoft Advertising and OpenAI Ads, every account, one connector.
