Best Opus Growth MCP alternatives in 2026
Opus Growth (opus-growth.com) is a hosted MCP connector: you paste one link into Claude or ChatGPT, sign in to your accounts once, and the assistant reads and changes your Google Ads, Meta, Microsoft Advertising, TikTok and LinkedIn ad accounts, alongside Google Analytics, Search Console, Tag Manager, Business Profile and YouTube. It launched on Product Hunt on 21 July 2026 as a Google Ads connector and has added the other networks since. Read on its own site on 12 October 2026: a free trial of 75 credits that never expire, no card; Pro at $49 a month for one ad account per platform; Agency at $99 a month with unlimited credits and client accounts through a manager account; Enterprise from $299 a month plus $49 per seat. Every change is shown as a preview with the old and new values and waits for your approval.
This page is about Opus Growth the ads connector, not the agency Opus Growth Partners or Anthropic's Claude Opus models. People look past it for one of four reasons: they do not work in Claude or ChatGPT all day, or do not want to pay for an assistant on top; they are not running ads yet, which Opus Growth itself says it is not for; they need Amazon or ChatGPT Ads, which it does not list; or they only want to read their numbers. If you already run ads on more than one network and spend your working day in Claude or ChatGPT, Opus Growth is built for exactly that, at a price few ads tools match. AgentCeres is the pick for the first two reasons: its own workspace, a website it builds and hosts, and SEO, social and ads agents, from $39 a month.

The shortlist
Adspirer
Top pickAn MCP server that puts an AI paid-media manager into ChatGPT, Claude, Cursor and other assistants, across Google, Meta, LinkedIn, TikTok, Amazon and ChatGPT Ads.
Pros- A free plan with 15 tasks a month and no card; Plus is $49 a month for 150 tasks, with larger plans at 600 and 3,000 tasks, or $40, $83 and $167 a month billed annually — the figures its page shows first (adspirer.com/pricing, read 2026-10-12)
- Amazon Ads and ChatGPT Ads are on its list; Opus Growth's are Google, Meta, Microsoft, TikTok and LinkedIn
- New campaigns are created paused and high-impact changes wait for your approval; it charges by task, never a percentage of ad spend
Cons- No Microsoft Advertising on its list of six networks
- A task is not a campaign: its own page says a full multi-platform launch costs more than one
- Running many clients means the top self-serve plan (5 active accounts per platform) or a custom Agencies & Enterprise deal
- Pricing:
- Free; from $49/mo ($40 yearly)
- Best for:
- Advertisers who also sell on Amazon or test ChatGPT Ads
GoMarble
AI agents for paid-media teams that analyze Meta, Google, TikTok, Microsoft Ads, GA4, Shopify and Klaviyo together, from its own app, Slack, or Claude and ChatGPT through MCP.
Pros- Reads store and email data beside the ads — Shopify and Klaviyo as well as GA4 — so a drop in sales can be traced past the ad account
- From Operator up, approvals and questions in Slack and an audit trail of every agent action
- A read-only Copilot plan for teams that want analysis, creative breakdowns and competitor research without any agent touching live campaigns
Cons- Copilot, the read-only plan, is $139 a month billed monthly; agents that launch and edit campaigns start on Operator at $399, and Scale is $799 (gomarble.ai/pricing, read 2026-10-12)
- Each plan is capped by monthly ad spend (up to $50K on Copilot, $500K on Operator) and by ad accounts and seats
- Unused AI credits do not roll over, and extra credits are $100 per 1,000
- Pricing:
- $139–$799/mo; 7-day trial
- Best for:
- Media teams spending tens of thousands a month across Meta and Google
AgentCeres
AgentCeres — the AI Growth Officer — is a managed team of AI marketing agents for SEO, GEO, social, ads, PR and community that also builds and hosts your website.
- Growth Officer
- Research agent
- SEO agent
- Social media agent
- Ads agent
- Influencer agent
- Launch & PR agent
- GEO agent
- Community agent
- Customer feedback agent
Pros- Its own workspace: no Claude or ChatGPT subscription to add, and no connector link to set up
- Builds, publishes and hosts your website and reports its visits and form submissions — useful before there is any ad account to manage
- A free plan and a 14-day trial with no card, then $39 or $99 a month flat for the account
Cons- Its ads agent works in Google Ads, Meta Ads, TikTok Ads, Apple Search Ads and ChatGPT Ads, not Microsoft or LinkedIn; in a connected ad account every change is a card you approve
- A defined list of Google Ads changes — campaigns, ad groups, keywords, locations, budgets and responsive search ads — rather than every campaign type a dedicated ads connector covers
- Not an MCP server you can plug into your own Claude or ChatGPT
- Pricing:
- Free plan; $39–$99/mo flat
- Best for:
- Founders who need the site and the marketing, not only the ad account
Google Ads MCP server
An open-source MCP server published on GitHub under Google's googleads organization that lets an AI assistant query a Google Ads account through the Google Ads API.
Pros- Free and open source; you run it yourself, so your data goes only to the assistant you connect
- Its search tool can pull anything the Google Ads API reports, with the API's own field and metric metadata available to the assistant
- Lives in the same GitHub organization as Google's Google Ads API client libraries, and its resources point the assistant at the API's current version and release notes
Cons- Read-only: its tools are search, resource metadata and a list of accessible accounts, so it cannot pause, edit or create anything
- Google Ads only
- Setup means Python, a Google Cloud project with the Google Ads API enabled, OAuth credentials and possibly a developer token — the steps Opus Growth exists to remove
- Pricing:
- Free (open source)
- Best for:
- Developers who only want to query their Google Ads data

Before you trust "nothing changes until you approve", look at one real preview. An approval is only as good as what the screen in front of you shows. In August 2026 one of our own approval cards asked a customer to authorize a public Instagram post while showing nothing but two ID numbers: the caption and the image had gone through an earlier step that never needed approval. We rebuilt it so that the post itself is what you approve. Opus Growth describes the right design — the old value and the new one, side by side — and so do the others here. Whichever you try, ask it to prepare one change on a small campaign first and read what the preview actually shows: for a budget, both numbers; for an ad, the words that will run.
Count the assistant in the price. Opus Growth and Adspirer run inside an assistant you pay for separately; Opus Growth's FAQ names the Claude Pro, Max, Team and Enterprise plans, plus ChatGPT, Cursor and Claude Code. Ad spend is paid to each ad network on top of every tool on this page, and websites are a separate Opus Growth product, the AI Server, from $29 a month.
How we checked. Read on 12 October 2026: opus-growth.com, its pricing page and FAQ, and its Product Hunt launch page; adspirer.com and adspirer.com/pricing, including the monthly prices in its pricing markup; gomarble.ai and gomarble.ai/pricing; and the README of the Google Ads MCP server on GitHub. For AI agents that run the ads themselves rather than through your assistant, see Sprites AI alternatives and Uplane alternatives; on our side, ads are the job of our Ads agent.

FAQ
- How much does Opus Growth cost?
- Read on opus-growth.com on 12 October 2026: the free trial is 75 credits that never expire, with no card and no automatic charge. Pro is $49 a month for 5,000 credits and one ad account per platform; Agency is $99 a month with unlimited credits and every client account through a manager account; Enterprise starts at $299 a month plus $49 per seat. Payments go through Paddle in US dollars. The pricing page has a yearly toggle, but the yearly figures were not in the page text we read. A paid Claude plan or ChatGPT, and your ad spend, are extra.
- Can Opus Growth change my ads without asking?
- Not according to its FAQ: every write is first shown as a preview, a dry run of exactly what will change, and nothing runs until you approve it. Budget increases are also capped at +50% per change, every change is written to an audit log, and the previous value is kept so a change can be undone. The Agency plan adds a 50% budget lock and a per-account audit log by default.
- Does Opus Growth build websites?
- Yes, as a separate product. Its AI Server builds and publishes sites you describe in Claude or ChatGPT on a server of your own, at $29, $39 or $79 a month for 10, 30 or 80 GB, with no per-site fee; a free trial runs on a subdomain and a custom domain needs an AI Server plan. For a WordPress site you already host, its plugin is $20, $50 or $100 a month for 1, 5 or 25 sites, and an AI Server plan includes one.
- Is there a free Google Ads MCP server?
- Yes. Google's googleads organization on GitHub publishes an open-source Google Ads MCP server. It is read-only — its tools search the account, describe API resources and list the accounts you can reach — and you set it up yourself with Python, a Google Cloud project with the Google Ads API enabled and OAuth credentials, plus a developer token if your setup needs one. It suits developers who want to ask questions of their data; for changes, you need a connector like Opus Growth or Adspirer, or an agent that runs the account.
