Bill for outcomes, not tool subscriptions — run client audits and changes from one chat
Opus Growth is a hosted MCP connector for the independent consultant who runs a handful of client accounts and gets paid for results, not for hours lost in dashboards.
Ask in plain English
›Run a full audit on this client's Google Ads account: missing conversion tracking, campaigns with no negatives, bidding strategies that don't match the goal, and budget sitting in underperformers.
›Build this month's report for my client: Google Ads and Microsoft spend, conversions and CPA, GA4 sessions and conversions by channel, and the top Search Console queries.
›Pull the last 60 days of search terms for this account, group the wasted spend by theme, and draft a negative keyword list for me to approve.
Paste one URL into Claude or ChatGPT, sign in with Google, and you can audit an account, pull a client report and make approved changes across Google Ads (69 tools), Microsoft Advertising (30), TikTok Ads (25) and LinkedIn Ads (20) — with GA4, Search Console and Google Tag Manager alongside for the measurement work. Every change runs as a dry-run preview you approve first, and every applied action lands in an audit log you can show a client. Pro at $49.99/month with 5,000 actions covers one or two clients comfortably; when the roster grows, Agency at $99.99/month adds unlimited actions and MCC multi-account support. Start free with 75 actions and no card.
What you can do
An account audit in minutes, not an afternoon
New-client discovery usually eats a day: combing the account for missing conversion tracking, no negatives, the wrong bidding strategy, budget stuck in the wrong campaigns. Ask for an audit instead and get the findings back in minutes — every campaign flagged with what is wrong and why. You spend your time on the recommendation and the pitch, not on the manual crawl, and you can run the same audit monthly to catch drift.
Client reports without the reporting-tool bill
Reporting is billable time you rarely get to bill for. Pull spend, conversions, CPA and week-over-week change per client across every live channel, add GA4 and Search Console for the organic side, and hand over a clean summary — without paying for a separate reporting platform per seat. Month-end turns into one prompt per client instead of an evening of copy-paste.
One connection instead of a stack of subscriptions
A freelancer's margin dies by a thousand subscriptions — one tool for reporting, another for audits, another to check tracking. One connector replaces that layer: Google Ads, Microsoft, TikTok and LinkedIn plus GA4, Search Console, Tag Manager and YouTube, from the Claude or ChatGPT you already pay for. No API keys, no data warehouse, no per-seat license creeping upward as you take on more work.
Make changes fast, with a record you can show the client
Client work has to move quickly and stay defensible. Describe a change — negatives, a budget trim, a bidding switch, a new campaign — and the assistant prepares it as a preview showing current and proposed values. Nothing reaches the account until you approve, new campaigns are created paused, and every applied action is written to an audit log. So when a client asks what you did last week, you have the record, not a reconstruction.
Start on Pro, move to Agency when the roster grows
Pro at $49.99/month with 5,000 actions comfortably covers one or two clients doing regular audits, reporting and optimization. When the roster grows, Agency at $99.99/month removes the ceiling and adds MCC and multi-account support, so a single connection reaches every client account you've been authorized for. Your tooling scales with the business instead of ahead of it. Yearly billing is $499.99 and $999.99.
Win the pitch with a real audit, not a generic deck
The fastest way to win a retainer is to show the prospect what they're leaving on the table. Run an audit on their account during the pitch — wasted search-terms spend, broken conversion tracking, campaigns with no negatives — and walk in with specifics. The free trial's 75 actions are enough to audit an account before you've signed anything, so the first value you deliver comes before the first invoice.

Sign in with Google and pick the client accounts
Hosted OAuth handles authorization. Sign in with Google, connect the platforms your clients run on, and select which accounts — including manager/MCC hierarchies once you're on Agency — the assistant may work with. Access stays scoped to exactly what you approve. Setup takes about 60 seconds.

Start asking in plain language
Ask for an account audit, a client report, or a batch of negatives. Reads return instantly; every write comes back as a preview you approve first, and applied actions land in the audit log. The free trial includes 75 actions and asks for no card — enough to audit an account before a client has signed.

Frequently asked questions
The agencies page is built for larger, multi-seat shops running big rosters on Agency. This is the solo consultant's angle: the same tools and the same safety guarantees, but the emphasis is doing audits, reports and changes fast for a few clients on Pro, and moving to Agency only when your roster outgrows it. There is no separate "freelancer plan" — you choose between Pro and Agency based on how many accounts you run and whether you need MCC.
Yes, and it is one of the strongest ways to use it. The free trial's 75 actions are enough to run an account audit — wasted search-terms spend, missing or broken conversion tracking, campaigns with no negatives, bidding that doesn't match the goal — so you can walk into the pitch with concrete findings instead of a generic deck. You need the prospect's authorization on the account; once you have it, the audit takes minutes.
Start on the free trial: 75 actions, no card. Pro at $49.99/month with 5,000 actions covers one or two clients doing regular audits, reporting and optimization. Move to Agency at $99.99/month when the roster grows — it removes the action ceiling and adds MCC and multi-account support, so one connection reaches every client account you're authorized for. Yearly billing is $499.99 and $999.99, in USD through Paddle, cancel anytime.
Yes. On Agency, a single connection at the manager (MCC) level reaches every client account you've authorized, with the correct login-customer-id sent on each Google Ads request — no separate sign-in per client. You name the client or account ID and the assistant works there, then moves when you say so. On Pro you connect the individual accounts directly, which is fine for a small roster.
Every applied action is written to an audit log: what changed, on which account, and when. On Google Ads the native change-history tool sits alongside it. So when a client asks what you did last week — or you need it for your own invoicing — you pull the record instead of reconstructing it from memory. It is the same trail that lets you take over an account from a previous consultant and see exactly what state it's in.
No — replacing the stack is the point. There is no API key to store, no Google Ads developer token to apply for, no OAuth app to register, no server to run and no data warehouse to maintain. You paste one URL into the Claude or ChatGPT you already use, sign in with Google, pick the accounts, and you're working in about a minute. Your authorization also carries across apps, including Cursor and other MCP-compatible clients.
Live today: Google Ads (69 tools), Microsoft Advertising (30), TikTok Ads (25) and LinkedIn Ads (20), plus Google Tag Manager (18), GA4 (10), Search Console (6) and YouTube (5) — 180+ live tools on one connection, out of a 200+ tool catalogue. Two integrations are finished but not live yet, and we won't imply otherwise: Meta Ads (27 tools) is in platform review and Google Business Profile (7 tools) is waiting on API access. Both open the moment approval lands.
