Test the connection
Ask Gemini: "Show my Meta ad performance last week"
Gemini returns spend, impressions, clicks, CTR, and ROAS broken down by campaign. The connection is live.
PaidSync vs Meta's Own MCP Server
Meta launched their own MCP server at mcp.facebook.com in April 2025. It gives AI assistants direct access to Meta platforms only.
PaidSync connects Meta Ads alongside Google Ads, LinkedIn Ads, TikTok Ads, GA4, Google Search Console, GTM, and Merchant Center. If you run ads on more than one platform, PaidSync is the practical choice: one API key, one MCP endpoint, all 630+ tools. The two servers are complementary rather than competing.
What Gemini Can Do with Meta Ads
Once connected, Gemini has live access to your Meta Ads data and can take action on it in the same conversation.
- Pull weekly performance. Gemini returns spend, impressions, CPM, CTR, and ROAS for any date range you specify across all your ad accounts.
- Identify top creatives. Gemini ranks your ads by ROAS or CTR and tells you which creatives to scale and which to cut.
- Adjust budgets. "Shift $500 from the awareness campaign to the retargeting campaign" runs as a real change after your approval.
- Duplicate winning ad sets. Gemini copies your best-performing ad sets to new audiences without manual setup in Ads Manager.
- Cross-platform view. Ask Gemini "compare my Meta and Google spend last month" and it pulls both from a single query.
Note on Meta permissions. PaidSync uses the ads_management permission which requires your Meta app to have Standard Access for write operations. PaidSync's app is approved for Standard Access. You do not need to apply separately.
Meta Ads prompts to try in Gemini
Each prompt runs on the PaidSync tools named after it and uses one or more of your tasks. Prompts 4 and 5 preview a change before anything applies.
- "Review my Meta campaigns from the last 30 days and rank the five biggest problems by spend." Runs
get_fb_performanceandget_fb_adset_performance. - "How much did I spend on Meta this week and what was my ROAS?" Runs
get_fb_performance. - "Find ad sets with a frequency above 3 and a higher CPM than last week." Gemini runs
get_fb_adset_performancefor both weeks. It returns frequency, and CPM comes from spend and impressions. - "Pause ad sets with a CPA above $40 in the last 14 days." Runs
get_fb_adset_performance, thenpause_fb_adsetas a preview first. - "Build a 1% lookalike audience from my existing Purchasers custom audience." Runs
create_fb_lookalike_audience, which previews first.
Why run Meta Ads from Gemini
If you already work in Gmail, Docs, Sheets and Google Ads, running Meta Ads from Gemini keeps the work in one place. Through PaidSync, Gemini reads your numbers from Meta's API instead of from text you paste into the chat, with 83 Meta tools for reporting and changes.
Frequently Asked Questions
How do I connect Meta Ads to Gemini?
Sign up at paidsync.ai, connect Meta Ads via Facebook OAuth, then add PaidSync to Gemini CLI with gemini mcp add --transport http, or have your Gemini Enterprise admin add it under Connected apps. The whole process takes 2 minutes.
Is PaidSync free to use with Meta Ads and Gemini?
Yes. PaidSync has a free plan with 15 tasks per month at $0. Paid plans start at $99/month for Pro. No credit card required to start.
What is Meta's own MCP server and how does it differ from PaidSync?
Meta launched their own MCP server at mcp.facebook.com in April 2025. It covers Meta platforms only. PaidSync connects Meta Ads alongside Google Ads, LinkedIn Ads, TikTok Ads, Snapchat Ads, Reddit Ads, Pinterest Ads, Microsoft Ads, GA4, and 5 other platforms in one connection. If you run cross-platform campaigns, PaidSync is the better choice.
Can Gemini make changes to my Meta Ads campaigns?
Yes. Gemini can create campaigns, adjust budgets, pause ad sets, update audiences, and duplicate top-performing ads. Gemini's own confirmation prompt is the human check before a change runs.
What Meta Ads permissions does PaidSync request?
PaidSync requests ads_read and ads_management permissions via Facebook OAuth. This gives read and write access to campaigns, ad sets, ads, audiences, and performance data for the connected ad account.
Does PaidSync work with Gemini Pro?
Yes. PaidSync works with Gemini at gemini.google.com, Gemini Pro, and Gemini Apps. The MCP endpoint is https://mcp.paidsync.ai/mcp. Sign in with your PaidSync login when Gemini prompts.
Can I also connect Google Ads to Gemini through PaidSync?
Yes. The same PaidSync sign-in connects all 14 platforms to Gemini. See the Connect Google Ads to Gemini page at paidsync.ai/connect/google-ads-to-gemini for platform-specific setup details.
Will Gemini make changes to my Meta Ads account without asking?
Not by default. New campaigns and ads start paused or as drafts, budget edits run as a preview first, and live pauses, enables and removals need an explicit confirmation flag. These are defaults, not locks, and Gemini's own confirmation prompt is a second check.
