Claude Fable 5 for Google Ads and Meta Ads.
Google Ads runs on keyword auctions. Meta Ads runs on audience and creative fatigue. Fable 5 is the first Claude model that runs both from one chair — here are the workflows, prompts, and the guardrails that make it safe to let it act.

Running Google Ads well and running Meta Ads well have always meant switching seats — different data model, different levers, different failure modes.
Google Ads is a keyword auction: you win on intent, measured in GAQL against search terms and quality score. Meta Ads is an audience auction: you win on relevance, measured in ad-set frequency and creative fatigue. Fable 5 is the first Claude model reliable enough to hold both data models at once — pull live performance from each, diagnose the highest-value fix, apply it within guardrails you set, and repeat on a schedule.
The four-stage Fable 5 workflow
Diagnose — wasted-spend and account-health audit across both platforms
Optimize — bid, budget, and creative-fatigue fixes as ready-to-run prompts
Automate — guardrails and approval workflow so Claude can act safely
Track — weekly performance across both platforms vs your targets
This doesn’t replace a media buyer — it removes the repetitive half of the job. Diagnosing wasted spend and drafting the weekly report are exactly what a scheduled model should be doing; strategy and creative direction still need a person. Connect the Ryze MCP once so Fable 5 reads both live accounts, then run the four stages below.
- Stage 1: Diagnose — where spend is wasted on each platform, and why
- Stage 2: Optimize — the specific bid, budget, and creative fixes
- Stage 3: Automate — guardrails so Claude can apply fixes safely
- Stage 4: Track — both platforms’ performance on one weekly report
Google Ads vs Meta Ads: what actually differs
Same goal — spend efficiently — completely different mechanics. Google rewards intent-matching and quality score. Meta rewards audience relevance and fresh creative. Here’s the same job, two platforms.
| Google Ads | Meta Ads | |
|---|---|---|
| The win | Winning the auction on intent | Winning attention with the right audience |
| Measured by | Quality score, CPC, search terms | Frequency, CTR, creative fatigue |
| What breaks | Wasted spend on low-intent keywords | Ad fatigue as frequency climbs past 4 |
| Data model | GAQL against keywords + auctions | Ad sets, audiences, and catalog |
| Key asset | Negative keywords + bid strategy | Fresh creative + audience overlap control |
| The Fable 5 job | Find wasted spend, fix bids | Catch fatigue, rotate creative, cap frequency |
For the individual per-platform workflow libraries, see using Claude for PPC management and 9 Claude workflows for Google and Meta Ads. This guide runs both from the same Fable 5 chair on a schedule.
The prerequisite: live account access
None of the workflows below work without Claude actually seeing your live account data. Google Ads and Meta Ads both shipped official MCP servers in April 2026 — but they took very different approaches, so start here before Stage 1.
Google Ads — official MCP is read-only
Requires a developer token, a Google Cloud project, and OAuth credentials. Three tools, no write access. Good for reporting; not built for autonomous fixes on its own.
Meta Ads — official MCP is hosted
One Meta Business OAuth click, no developer app. 29 tools, including write access — campaigns you create start paused for safety.
Ryze MCP — both platforms, one URL
Connects Google Ads and Meta Ads with standard OAuth on both sides — no developer token — and adds read AND write access plus the guardrail layer Stage 3 below builds on.
Either way: verify before you automate
Run every workflow below read-only for two weeks first. Confirm the diagnosis is right before you let Claude apply anything.

1 · Diagnose — wasted spend + account health
You can’t fix what you haven’t measured. One workflow finds where Google Ads spend leaks to low-intent search terms; the other finds where Meta ad sets have gone stale. Run both before touching anything.
01 · Google Ads Wasted-Spend Audit
Fable 5Where is Google Ads spend leaking?
Pulls search terms with spend and zero or near-zero conversions, flags missing negative keywords, and ranks the fixes by dollars recovered.
02 · Meta Ads Fatigue Audit
Which ad sets have gone stale?
Flags ad sets with frequency above 4 and rising CPM — the classic fatigue signature — before performance visibly drops.
2 · Optimize — bid, budget, and creative fixes
Diagnosis becomes a fix list. These two prompts turn Stage 1’s findings into the exact changes to make on each platform — still draft-only until Stage 3 gives Claude permission to apply them.
03 · Google Ads Bid & Budget Fixer
Fable 5Reallocate budget to what's working
Compares CPA against target by campaign, then proposes specific bid and budget moves — cut here, raise there — with the expected impact.
04 · Meta Ads Creative Refresh Planner
Which creative to swap, and with what
Pairs fatigued ad sets from Stage 1 with the account's best-performing creative angles, so the refresh is informed, not a guess.

3 · Automate — guardrails and approval
This is the stage that makes it safe to let Claude apply changes instead of only drafting them. Three minimums: a hard spend cap, a pre-approved action list, and a change log you can audit afterward.
05 · Guardrail Definition
Set the limits before granting write access
Turns a plain-English limit into an explicit rule set Claude checks before applying anything — the single most important prompt on this page.
06 · Guardrailed Auto-Fix
Fable 5Apply the pre-approved fixes, log the rest
Runs Stage 1's diagnosis and Stage 2's fix list, applies only what's pre-approved under the guardrails, and surfaces everything else for a yes/no.
Ryze AI is the autonomous platform that executes Google Ads and Meta Ads changes 24/7 within guardrails you set — not just recommends them. Start read-only for two weeks, confirm the diagnosis was right, then turn on write access for the narrowest, highest-confidence action first.
4 · Track — one weekly report, both platforms
A dashboard you have to log into never gets checked often enough. One scheduled prompt pulls both accounts, compares to target and last week, and tells you where to look before you've opened your laptop.
07 · Cross-Platform Performance Report
Spend, CPA, and ROAS vs target, every Monday
Reads this week's spend, CPA, and ROAS from both platforms, compares each to target and to last week, and names the 3 accounts or campaigns furthest off track.
Setup: connect your accounts in 30 seconds
Every workflow above needs live data from both platforms. One MCP URL gives Fable 5 Google Ads and Meta Ads access together — paste it into Claude once and every scheduled prompt runs against fresh numbers.

Frequently asked questions
What is the difference between managing Google Ads and Meta Ads with Claude?
Google Ads is intent-based — you bid on what someone is actively searching for, measured with GAQL against a keyword-and-auction data model. Meta Ads is interest and behavior-based — you target who someone is, measured through ad-set frequency, creative fatigue, and audience overlap. The prompts and guardrails differ because the underlying decisions differ.
Why use Claude Fable 5 specifically for ad management?
Ad-ops is a multi-step reasoning job across two account structures: pull live data, diagnose the highest-value fix, apply it within guardrails, repeat weekly without drifting off the rules. Fable 5 is the first Claude model reliable enough to run that loop unattended. Earlier models could draft a report; Fable 5 can operate within limits you set.
Can Claude actually pause campaigns and change budgets, or just recommend it?
Both, depending on the MCP you connect. Read-only access gets you ranked fix lists and draft reports. A write-capable connector lets Claude apply changes directly — but only within the guardrails you define first: spend caps, pre-approved actions, and a change log.
What guardrails should I set before letting Claude manage ad spend?
Three minimums: a hard daily or per-change spend cap, a list of pre-approved actions versus actions that always need a human, and a running log of every change so you can audit it. Start read-only for two weeks, confirm the recommendations were right, then turn on write access for the narrowest action first.
How do I get a weekly performance report without building a dashboard?
Connect Claude to both ad accounts via MCP and run one scheduled prompt that pulls spend, CPA, and ROAS from each platform, compares to targets and the prior week, and flags what's drifting. That replaces a manual dashboard pull with one Monday-morning prompt.
Does Fable 5 replace a media buyer?
No — it removes the repetitive half of the job. Diagnosing wasted spend, drafting the report, and applying pre-approved fixes are exactly what a scheduled model should run. Strategy and creative direction still need a person.
Where do I schedule these prompts?
In Claude Cowork → Scheduled: paste the prompt, name it, pick a frequency, save. Each card above lists its suggested cadence — Diagnose and Track weekly on Mondays, Optimize on Tuesdays, Automate's guardrails set once and reviewed monthly.
Does this only work if I use Ryze?
No — every prompt above works with any MCP that gives Claude read access to Google Ads and Meta Ads, including the official Google and Meta MCP servers. Ryze adds write access without a developer token and the guardrail layer Stage 3 is built on, but the workflows themselves are portable.
