69 Google Ads tools, including real write actions
This is not a read-only reporting bridge. Create Search, Performance Max, Demand Gen and App campaigns, build ad groups and responsive search ads, pause or enable anything — all from a chat message.
Search-terms mining into negative-keyword lists
Ask for wasted spend in the last 30 days and your assistant pulls the search-terms report, ranks the money-losing queries, and adds them as negatives at the right match type once you approve.
Bidding strategies and budgets under your control
Switch campaigns between Target CPA, Target ROAS, Maximize Conversions or manual bidding, and reset daily budgets across an account — with the exact before/after values shown before anything changes.
Performance Max asset management
Update PMax asset groups, swap headlines and descriptions, and upload new images without opening the Google Ads UI, so creative refreshes take minutes instead of an afternoon.
MCC-wide reporting across every client account
Agency accounts work natively via login-customer-id. Ask for spend, CPA and conversion trends across all managed accounts in one question and get a single ranked answer instead of ten browser tabs.
Keywords, extensions, audiences and conversion actions
Add or pause keywords, manage sitelinks, callouts and other extension assets, adjust campaign targeting and ad schedules, and configure conversion actions — the day-to-day work, done conversationally.

Start asking in plain English
Type a request like "show me last week's Google Ads performance by campaign" or "pause every ad group with zero conversions and over $200 spend." Reads run instantly; every write comes back as a dry-run preview you approve before it is applied.
Ask in plain English
›Show me Google Ads spend, conversions and CPA by campaign for the last 30 days versus the previous 30.
›Pull the search-terms report for my Search campaigns and add the top 20 irrelevant queries as phrase-match negatives.
›Which campaigns are over Target CPA this month? Cut their daily budgets by 20% and show me the change first.
›Refresh the Performance Max asset group for the Summer Sale campaign with these five new headlines and two descriptions.
›Across my whole MCC, rank client accounts by conversion volume and flag any account whose CPA rose more than 25% week over week.
›Create a new Search campaign for "enterprise CRM software" with a $150 daily budget, Maximize Conversions bidding, and three responsive search ads.
Frequently asked questions
MCP (Model Context Protocol) is the open standard AI assistants use to connect to external systems. A Google Ads MCP connector exposes Google Ads as a set of tools your assistant can call directly. Opus Growth is a hosted MCP connector with 69 Google Ads tools, so Claude or ChatGPT can read your account data and make changes inside it without any custom code.
It writes. Opus Growth can create Search, Performance Max, Demand Gen and App campaigns, build ad groups and responsive search ads, set budgets and bidding strategies, add and pause keywords, manage negative keywords, extensions, audiences, ad schedules and conversion actions. Reporting is included, but real write actions are the point — that is what separates it from read-only data connectors.
Nothing reaches Google Ads until you say yes. A write comes back to you first as a dry run — the campaign, the current value, the proposed value — and then stops and waits. That is what makes aggressive bulk changes safe to ask for: you always see the diff before it lands.
Yes. Opus Growth is MCC-safe: it supports login-customer-id so you can work across every managed account from one connection, with per-customer isolation and audit logging of actions taken. The Agency plan at $99.99/month adds unlimited actions and multi-account management for exactly this workflow.
Yes, and not only those two: Claude (claude.ai and Claude Desktop), ChatGPT (developer mode / connectors), Cursor, and any other MCP-compatible app. Because Opus Growth is a remote hosted connector, you add the same URL — https://mcp.opus-growth.com — everywhere, and your Google Ads authorization carries across apps.
No. Opus Growth handles the Google Ads API access for you. You sign in with your normal Google account through hosted OAuth and authorize the ad accounts you want to use. There are no developer tokens to apply for, no API keys to paste, no OAuth app to register and no server to run.
There is a 7-day free trial with 50 actions and no credit card required. Pro is $49.99/month for 5,000 actions across all live platforms, and Agency is $99.99/month for unlimited actions plus MCC and multi-account support. Yearly plans are $499.99 and $999.99. Billing is in USD through Lemon Squeezy as merchant of record, and you can cancel anytime.
Within a minute of connecting you can pull performance reports by campaign, ad group, keyword or device, run a search-terms audit and add negatives, adjust budgets and bidding strategies, refresh Performance Max and responsive search ad assets, and pause underperformers. Most teams start with a wasted-spend audit because it pays for the subscription immediately.
The same connection also covers Microsoft Advertising (30 tools), TikTok Ads (25) and LinkedIn Ads (18), plus Google Tag Manager (18), GA4 (10), Search Console (6) and YouTube (5) — part of a 221-tool catalog. Two integrations in that catalog are not switched on yet: Meta Ads (27 tools) is built and complete but in final platform review, and Business Profile (7 tools) is waiting on Google quota approval. Both appear in your account automatically once approval lands.
