Why does agency tooling break on manager accounts?

Because a Google Ads manager account (MCC) needs the right login-customer-id on every request, and many tools send it once or not at all, which ends in "customer not found" on the third client. Opus Growth sends it on every call, so one connection at the manager level reaches every client you approved, alongside Meta, Microsoft, TikTok, LinkedIn and ChatGPT Ads, with every change previewed and logged.

add https://mcp.opus-growth.com/mcp in Claude and other MCP-compatible apps; in ChatGPT, open the published Opus Growth plugin at opus-growth.com/chatgpt, install it, approve the Opus Growth sign-in, then start a chat with @Opus Growth, sign in with Google, and your assistant can work across every client account you approve. Google Ads, Meta Ads, Microsoft Advertising, TikTok Ads, LinkedIn Ads and ChatGPT Ads, with login-customer-id handled correctly on every call, per-client isolation, audit logging, and a preview before anything is applied. The Agency plan is $99/month with unlimited credits and MCC support.

What it does for an agency

Each picture below is a real kind of request and the kind of answer Opus Growth gives inside ChatGPT or Claude.

MCC-safe: the right login-customer-id on every call

Manager account structures are where most agency tooling quietly breaks. Opus Growth sends the correct login-customer-id with every Google Ads request, so you connect once at the MCC level and reach every client account you approved, no separate OAuth per client, no "customer not found" on the third account, no re-authorizing halfway through a review. List your accounts, name a customer ID, keep working.

List the client accounts under my MCC.

Switch clients mid-conversation, across platforms

Ask about client A's Google Ads, then say "now client B's LinkedIn" and the thread carries on. One connection covers Google Ads, Meta Ads, Microsoft Advertising, TikTok Ads (including every advertiser under your Business Centers), LinkedIn Ads and ChatGPT Ads. A Monday portfolio review that used to mean fifteen logins becomes one conversation.

Now Juniper Home's Meta, then Alder Legal's LinkedIn: spend and leads this month.

Approval gates: nothing lands on a client account unseen

Every write is prepared as a preview first (the account, the entity, the current value and the proposed value) and it is sent to the platform only after you say yes. New campaigns and ad groups are created paused on multiple platforms and budget increases are capped, so even an approved bulk change cannot start spending a client's money on its own.

For my three clients over budget this month, cut daily budgets by 20%.

Audit logging and change history you can show a client

Applied actions are written to an audit log under per-client isolation, and Google Ads change history is available as its own tool. "What happened to this account on the 14th, and who did it?" becomes a question with an answer, whether the change came from your team, from the client, or from a platform auto-apply. On accounts you inherit from another agency, that is the first thing worth running.

Client reporting from paid, analytics and organic in one pass

Pull paid performance from Google Ads, Meta Ads, Microsoft Advertising, TikTok, LinkedIn and ChatGPT Ads, then add GA4, Search Console and YouTube for the organic picture, and use Google Tag Manager to verify the tracking behind the numbers. Reporting night turns into one prompt per client.

Unlimited credits on Agency, one flat $99/month

Roster work is bulk work: twenty search-terms audits, forty budget edits, a few hundred negatives. Pro at $49/month and 5,000 credits fits a business with one ad account per platform; the Agency plan at $99/month removes the ceiling entirely and adds MCC and multi-account access. Your cost stops scaling with how thorough you are.

Add Opus Growth

Prompts agencies run every week

Copy any of these into ChatGPT or Claude. The assistant reads your account and prepares the answer.

Across my MCC, rank every client account by spend, conversions and CPA for last week, and flag any account whose CPA rose more than 25%.

Switch to the Northwind account, pull the last 30 days of search terms, and prepare a phrase-match negative keyword list for my approval.

New client onboarding: run an account audit on customer ID 123-456-7890 and list every campaign with missing conversion tracking, no negatives, or a bidding strategy that does not match its goal.

Build the monthly report for Acme: Google Ads and Microsoft Advertising spend, conversions and CPA, GA4 sessions and conversions by channel, and the top Search Console queries.

Show me every change made in this client's Google Ads account over the last 14 days, who made it and when.

For my three clients over budget this month, cut daily budgets by 20% and show me the before and after values per account before applying anything.

Nothing reaches a client account without your yes.

Every change comes back as a preview first. If a request breaks a safety limit, the assistant says so and offers what is allowed.

  • Preview before every write

    You see the item, the current value and the new value before anything is applied.

  • Budget limits

    A budget can rise by at most 50% in one step and 100% within 24 hours, and a single cut cannot go deeper than 80%.

  • New campaigns start paused

    Campaigns and ad groups created from chat stay paused until you turn them on.

  • Every action is logged

    Applied changes are recorded with the account and the time.

Opus Growth for agencies: frequently asked questions

MCP (Model Context Protocol) is the open standard AI assistants use to call real tools. Opus Growth is a hosted, remote MCP connector: you paste https://mcp.opus-growth.com/mcp into ChatGPT or Claude once, and your assistant gains live platform tools across Google Ads, Meta Ads, Microsoft Advertising, TikTok Ads, LinkedIn Ads, ChatGPT Ads, Google Tag Manager, GA4, Search Console, YouTube and Google Business Profile. For an agency the practical effect is that the work you do per client, audits, negatives, budget edits, reporting, moves out of fifteen browser tabs and into one conversation. In ChatGPT, open the published Opus Growth plugin at opus-growth.com/chatgpt, install it, approve the Opus Growth sign-in, then start a chat with @Opus Growth.

Yes, natively. Opus Growth passes the correct login-customer-id on every Google Ads request, so a single connection at the manager level reaches the client accounts you authorized. You can list accounts, work in one customer ID, then move to the next without re-authorizing. MCC and multi-account access are included in the Agency plan.

Yes. Naming the client or the account ID is enough, the assistant targets that account for the next actions, then moves when you say so. The same conversation can cross platforms too: Google Ads for one client, LinkedIn for another, Microsoft Advertising for a third, without leaving the thread or reconnecting anything.

Approval gates. Every write action comes back as a preview first: the assistant shows the account, the object, the current value and the proposed value, and nothing is sent to the ad platform until you explicitly confirm. Reads run immediately. On top of that, new campaigns and ad groups are created paused on multiple platforms and budget increases are capped, so an approved change still cannot begin spending on its own.

Yes. Access is scoped to the accounts you authorized, data is isolated per customer, and applied actions are written to an audit log. Combined with the Google Ads change-history tool, you can reconstruct what changed in an account, when, and from where, which is what you need when a client asks why performance moved, or when you take over an account from a previous agency.

Agencies should take Agency at $99/month: unlimited credits plus MCC and multi-account support, which is the plan designed for roster work. Pro at $49/month includes 5,000 credits a month and suits a single business with one ad account per platform. Yearly billing is $490 and $990. Everyone starts on a free trial with 75 credits and no credit card. Billing is in USD through Paddle as merchant of record, and you can cancel anytime. There is also All-in-One at $149 a month, which adds an AI Server and 15,000 SEO credits every month, and Enterprise for teams, priced on request.

No. Opus Growth is hosted, including OAuth. There is no Google Ads developer token to apply for, no API keys to store, no OAuth app to register, no server to run and no ETL pipeline or data warehouse to maintain. The account manager who will use it can set it up themselves in about a minute: paste the URL, sign in with Google, pick the accounts.

Six ad networks are live today: Google Ads, Meta Ads (Facebook and Instagram), Microsoft Advertising, TikTok Ads, LinkedIn Ads and ChatGPT Ads. Google Tag Manager, GA4, Search Console, YouTube and Google Business Profile run on the same connection, so tracking, website traffic and local listings sit next to the ad numbers.
