LoomaScale vs Adspirer: Which AI Agent Should Run Your Google Ads?

LoomaScale and Adspirer are the same kind of product. Both are MCP servers: they hand ChatGPT or Claude real access to your ad accounts, so the assistant reads yesterday's spend and makes changes instead of giving advice about a screenshot you pasted. Both connect over OAuth, both create campaigns paused, and LoomaScale starts cheaper, but the sticker price is not what decides this.

Two things do. What you are metered on, and how far the Google Ads coverage actually goes.

What the two have in common

Worth saying plainly before the differences, because the overlap is real. Both are Google Ads AI agents in the sense this guide defines: a model with tools on a live account, not a chatbot or a rule.

• OAuth, never a password. You grant access from Google's own screen and revoke it there.
• Everything is created paused. Nothing either product builds starts spending on its own.
• Both work in ChatGPT and in Claude. Neither locks you to one assistant.
• Both are free to start and neither takes a percentage of your ad spend.

If you are choosing between them, you are not choosing between safe and unsafe. You are choosing between two designs.

What you are metered on

This is the difference you will feel every month.

Adspirer meters tool calls. Their own documentation puts it plainly: each tool invocation counts as 1 call, whatever the platform or the client.

LoomaScale meters neither calls nor messages. A plan covers a number of different ad accounts in a billing month — two on Starter, five on Business, twenty on Portfolio — and inside those accounts you ask as much as you like. An account counts once, the first time we read its data or change something in it, however often you come back to it that month. The same definition is written into our terms and our refund policy, not just the marketing page.

That sounds like an accounting detail until you watch an agent work. A single question — where am I wasting money — makes it list campaigns, pull insights, pull the search terms report, and then propose negatives. Four calls before you get a sentence back.

The follow-up costs the same again. So does the one after that, and the follow-up is where the real work happens: no, exclude the branded ones; now show me the same thing for last quarter.

Per-call metering quietly asks you to ration the agent's curiosity — to tell it to look at less so the audit stays cheap. That is exactly backwards. The thing worth pricing is how many accounts you are responsible for, which is the one number that does not change because you asked a better question.

Six platforms, or two done deep

Adspirer covers six ad platforms — Google, Meta, LinkedIn, TikTok, Amazon and ChatGPT Ads. LoomaScale covers two: Google Ads and Meta Ads. The Meta side is the newer and the smaller of them — 14 tools against 47 — and what it does for a wedding photographer is the honest measure of it.

If your spend is genuinely spread across three or more networks, breadth is the thing to buy, and this comparison ends here. Go buy breadth.

The rest of this is for the reader whose Google Ads account is the account that matters. There, 48 tools go somewhere specific:

• Sitelinks as a full set of operations. List, create, update and remove. Update rewrites the text or the destination in place, so the sitelink keeps its id and its performance history. Products that only add and unlink make you delete and rebuild, which throws the history away for a typo fix.
• Performance Max split into four tools. Asset group text, images and logos and YouTube video, search themes, and campaign-level brand assets are separate calls — so the agent can rewrite a headline without touching your creative.
• Conversion actions you can actually inspect. Counting type, attribution model, primary flag, click-through and view-through windows, all readable and most of them writable. With the honest caveat: conversions imported from GA4 are immutable through the Google Ads API. That setting lives in GA4 and no connector can change it. A tool that pretends otherwise fails at the moment you need it.
• The boring diagnostics that answer "why is nothing serving". A billing check that looks at account status, billing setup approval and exhausted account budgets, and a pacing check that finds enabled campaigns delivering nothing today.
• Insights broken out by geography and by audience, plus keyword research with monthly volume, competition and top-of-page bid estimates.

Breadth and depth are a real trade, not a marketing one. Six platforms is six API surfaces to keep current; two is a smaller promise kept closer to the metal.

The guardrails are tools, not promises

Guardrails written in a landing page are worth nothing. These are in the tool definitions:

• Everything created — Search campaigns, Performance Max campaigns, ad groups, ads — lands paused.
• Activating or resuming anything re-checks the campaign budget against your own daily cap first.
• The budget tool refuses budgets shared across several campaigns rather than moving money you did not mean to move.
• The account-level budget tool will raise a spending limit but will not set it to unlimited.
• Read and write are separate OAuth scopes. You can connect read-only, let the assistant audit and diagnose for a month, and grant write access when you have decided you trust it. More on vetting an MCP server, and the wider field of seven if two is too few to compare — or the Meta shortlist if Meta is the account in question.

The checks are written down before they run

Here is the part nobody else publishes. LoomaScale ships a library of standing checks — the recurring loop of a real account rather than one-off questions. Stop waste weekly. Check pacing daily. Move budget to winners weekly. Keep automation healthy. Find growth. Confirm last week's changes did not cost anything.

Two things make it more than a list of prompts.

Each check states its own cadence. Not one frequency picked for everything: pacing is a daily glance, reallocation is a weekly decision, and the card says which.

Each check names the tools it will call before you run it. You can read exactly what the agent is about to touch — which reads, which writes — instead of finding out afterwards. And the waste check carries a dollar threshold you set per account, because twenty dollars is generous at an $8 CPA and meaningless at $300.

The daily one, in full:

LoomaScale does not schedule these checks itself. For a scheduled review in ChatGPT or Claude, first verify that the scheduled run can access LoomaScale and return fresh account data. Follow the recurring-review guidance; otherwise, use a calendar reminder and run the saved prompt manually.

The free trial is an audit, not a countdown

Both are free to start. On LoomaScale every new account gets 14 days with unlimited ad accounts, and the clock starts with your first review rather than at signup — so connecting the account and reading the setup guide cost you nothing. There is no question budget to beat: inside those accounts you ask as much as the fortnight allows.

And the free path has a deliverable at the start of it rather than a timer to beat: connect Google Ads and the assistant reports the three findings costing you the most. If you want to run that yourself first, the full 30-minute audit is seven checkpoints with the prompts and the thresholds.

We run our own ads through it

Every Google Ads campaign LoomaScale runs was created from ChatGPT through the same connector you would be buying — three campaigns, one per language, from a single prompt, with the numbers published. The case study is here, including the four things the create tool deliberately leaves for a human.

Which one to pick

• Spend across three or more networks? Buy breadth. Adspirer covers more platforms than we do and says so accurately.
• Google Ads is the account that decides your quarter? Depth wins: in-place edits that keep their history, Performance Max broken into the pieces you actually change, and diagnostics for the days nothing serves.
• Do you ask follow-up questions? Then what you are metered on matters more than the sticker price, and pricing by ad account is the only version of it that does not punish you for digging.

Connecting takes a few clicks either way — ChatGPT or Claude — and the first audit costs you nothing.
