To connect Microsoft Ads (Bing Ads) to Gemini, add PaidSync from Gemini's connector directory, sign in, and ask Gemini to connect your Microsoft Advertising account. PaidSync is our pick because it gives Gemini 156 Microsoft Ads tools that read reports and make changes inside your existing campaigns, from pauses and budgets to new ad groups, keywords and ads, with no developer token or Azure app to set up. Microsoft's own MCP server is read-only (checked 30 Sep 2026).
PaidSync creates Microsoft Ads Search and Performance Max campaigns paused. Setup takes about 2 minutes, and it is free for 15 tasks with no credit card.
How to connect Microsoft Ads to Gemini with PaidSync
PaidSync joins Gemini as a custom app, or through Gemini CLI, Antigravity or Gemini Enterprise. No API key is needed, because Gemini connects with a PaidSync sign-in (OAuth).
Before you start
- Pick your Gemini surface in step 1. The Gemini app takes PaidSync as a custom app on a personal Google Account (18 or older, in the US, in English, with Keep Activity on). Gemini CLI, Antigravity and Gemini Enterprise cover work accounts and terminals.
- Signing in with Google? There is no separate sign-up. You pick Continue with Google in step 2, and your free PaidSync account (15 tasks, no credit card) is created when you press Approve.
- Prefer an email and password? Create the account at paidsync.ai/signup before you start. The sign-up link inside the sign-in window opens the website and does not bring you back to Gemini.
- Know which Microsoft account can open your Microsoft Advertising accounts. You use it in step 3. You need no Microsoft developer token and no Azure app.
Add PaidSync to Gemini
Gemini app, personal account. Open gemini.google.com, go to Settings, then Connected Apps (if you do not see it, open Personal Intelligence first), and under Custom apps choose Add a custom app. Paste the PaidSync server URL and click Next. PaidSync registers itself, so there is no API key to copy and nothing to fill in under Advanced features.
https://mcp.paidsync.ai/mcpAdd it on the web once and it works in the Gemini mobile app too. Google limits custom apps to personal Google accounts, age 18 and over, in the US, in English, with Keep Activity turned on. A work or school account cannot add them, so use Gemini Enterprise below instead.
Gemini CLI. Run the command, then type /mcp auth paidsync and sign in with your PaidSync login. Google replaced Gemini CLI with Antigravity CLI for unpaid-tier and Google One users on 18 June 2026, so those accounts use Antigravity below.
gemini mcp add --transport http paidsync https://mcp.paidsync.ai/mcpGemini Code Assist agent mode in VS Code reads the same settings file as Gemini CLI. Add this to ~/.gemini/settings.json:
{
"mcpServers": {
"paidsync": { "httpUrl": "https://mcp.paidsync.ai/mcp" }
}
}Antigravity uses a different key. Open the agent panel menu, choose MCP Servers, then Manage MCP Servers and View raw config, or edit ~/.gemini/config/mcp_config.json, and add the server with serverUrl. Antigravity signs in by dynamic client registration on its own:
{
"mcpServers": {
"paidsync": { "serverUrl": "https://mcp.paidsync.ai/mcp" }
}
}Gemini Enterprise, Business edition. A team admin adds PaidSync under Settings and help, then Manage team, then Connected apps, then Add MCP Server. PaidSync serves the Streamable HTTP transport Gemini requires and OAuth 2.0 at https://api.paidsync.ai/authorize and https://api.paidsync.ai/token. Email support@paidsync.ai for the client credentials that form asks for.
Sign in to PaidSync and press Approve
The PaidSync sign-in screen opens. Pick Continue with Google, or sign in with your PaidSync email and password. A PaidSync screen then asks whether to allow Gemini to manage your ad accounts via PaidSync. Press Approve and PaidSync is connected.
New to PaidSync and signing in with Google? Your free account (15 tasks, no credit card) is created when you press Approve. The screen also mentions ad accounts already connected inside PaidSync. On a new account that list is empty until you finish step 3.
Connect your Microsoft Ads account and ask Gemini
In any chat, ask: "Connect my Microsoft Ads." Gemini replies with a link that opens Microsoft's own sign-in and consent screen. Sign in with the Microsoft account that can open your Microsoft Advertising accounts and accept. A page that says Microsoft Ads Connected appears, so close it and come back. PaidSync never sees your Microsoft password.
Then ask: "List my Microsoft Ads accounts." Gemini uses list_ms_accounts to show them and set_active_microsoft_account to pick the one you name. Connecting accounts and picking one uses none of your tasks. Now try: "Show my Microsoft Ads campaign performance for the last 7 days."
What PaidSync can and cannot do on Microsoft Ads
PaidSync has 156 Microsoft Ads tools. They read reports and change existing campaigns, including new ad groups, keywords and ads. They also create Search and Performance Max campaigns, paused.
What PaidSync can do
- Read reports. Gemini pulls campaign, ad group, keyword, search term, conversion, location and audience performance, with spend, clicks, impressions, conversions, revenue, CTR, average CPC and ROAS.
- Pause, enable and re-budget campaigns. Gemini pauses and turns campaigns back on, and changes a campaign's budget, name and status.
- Tune what already runs. Ad group status, names and CPC bids, keyword bids, match types and status, and bid adjustments by location, device and audience.
- Build inside an existing campaign. New ad groups, keywords, responsive search ads and dynamic search ad targets. Each new ad group, keyword and ad starts paused unless you say otherwise.
- Clean up and track. Negative keywords and shared negative keyword lists, website exclusions, audiences, UET tags and conversion goals.
What PaidSync cannot do
- Create Shopping or Audience campaigns. Create those in Microsoft Advertising, or import them there from Google Ads. PaidSync then builds inside them.
- Change bid strategies or labels. PaidSync has no Microsoft Ads tools for them, so those stay in Microsoft Advertising.
- Make ad formats other than responsive search ads. Responsive search ads are the one ad type PaidSync creates or edits on Microsoft Ads.
- Delete ads, ad groups or keywords. PaidSync pauses them instead.
Microsoft Ads prompts to try in Gemini
Each prompt runs on the PaidSync tools named after it and uses one or more of your tasks. Budget, negative keyword, ad group, keyword and ad changes preview by default before anything is sent to Microsoft.
- "Show my Microsoft Ads campaigns for the last 30 days with spend, clicks, conversions and ROAS." Runs
get_ms_performance, which returns spend, clicks, impressions, conversions, revenue, CTR, average CPC and ROAS for each campaign. - "Which search terms spent money in the last 30 days with no conversions? Preview adding the worst five as exact match negatives to the Brand Search campaign." Runs
get_ms_search_query_performance, thenadd_ms_negative_keywords, which previews by default and sends nothing until you approve. - "Pause the Spring Sale campaign." Runs
pause_ms_campaign. Ask forenable_ms_campaignto turn it back on. - "Preview raising the daily budget on the Brand Search campaign to $80." Runs
update_ms_campaign_budget, which previews by default and, once applied, reads the new budget back from Microsoft to check it. - "Add an ad group called Trail Shoes to the Running campaign with five phrase match keywords and one responsive search ad." Runs
create_ms_adgroup,add_ms_keywordsandadd_ms_responsive_search_ad. Each one previews by default, and the new ad group, keywords and ad start paused.
Why use PaidSync for Microsoft Ads in Gemini
It makes changes, not just reports. 156 Microsoft Ads tools read your data and work inside your existing campaigns, from pauses and budgets to negative keywords and new ad groups, keywords and ads.
No developer token or Azure app. You sign in with PaidSync and approve access on Microsoft's own consent screen. PaidSync handles the Microsoft Advertising developer token on its side.
Changes wait for you. In the PaidSync workspace, by default, every change is an approval card. In Gemini, budget, keyword and ad changes preview by default, and new ad groups, keywords and ads start paused.
One connection, 14 platforms. Microsoft Ads sits next to Google Ads, Meta, LinkedIn, TikTok and 9 more platforms, 630+ tools through one endpoint, so Gemini can compare Microsoft and Google results in the same chat.
Other ways to connect Microsoft Ads to Gemini
- Microsoft's own MCP server. Microsoft Advertising says it is available with read-only access (Microsoft Advertising, August 2026), and its setup guide has you register an Azure app with the Azure CLI and add it as a custom connector (checked 30 Sep 2026).
- Zapier. Zapier's Microsoft Advertising MCP lists four actions, all for customer lists and offline conversions (checked 30 Sep 2026).
- Build your own. Microsoft's Bing Ads API guide asks for a developer token, valid user credentials and a registered OAuth app (checked 30 Sep 2026).
How do I connect Microsoft Ads to Gemini CLI?
This guide is for the Gemini app. In Gemini CLI the same PaidSync connection is one command:
gemini mcp add --transport http paidsync https://mcp.paidsync.ai/mcpStart a session, type /mcp auth paidsync, and sign in with your PaidSync login in the browser window that opens. Gemini CLI stores the OAuth token for you. No key is pasted anywhere. Google replaced Gemini CLI with Antigravity CLI for unpaid-tier and Google One users on 18 June 2026, so those accounts add PaidSync in Antigravity instead, as step 1 shows. Then connect your Microsoft Ads account as in step 3.
Troubleshooting Microsoft Ads in Gemini
- The sign-in fails. Sign in to PaidSync the way you signed up, with Continue with Google or with your PaidSync email and password. Email users without an account create one at paidsync.ai/signup, then add PaidSync in Gemini again. If Microsoft's own consent screen fails, ask Gemini "Connect my Microsoft Ads" again for a fresh link.
- Gemini picked the wrong account. Ask Gemini to list your Microsoft Ads accounts and switch to the one you mean, by name or ID. It runs
list_ms_accounts, thenset_active_microsoft_account, and every Microsoft Ads request after that goes to the account you picked. Switching uses none of your tasks. - An account is not listed. PaidSync lists the Microsoft Advertising accounts that the Microsoft login you used can open. Check in Microsoft Advertising that this login has access to the account, or ask the account's admin to add you, then ask Gemini to list your accounts again. Still missing? Email support@paidsync.ai.
- Gemini says it has no Microsoft Ads tool. PaidSync shows Gemini a short starter list of tools to keep the chat light. Ask Gemini to call
paidsync_contextwithinclude_tools:['microsoft_ads']. It returns your connected platforms and the Microsoft Ads tool names, and Gemini then runs them throughpaidsync_exec. If PaidSync is missing from Gemini altogether, check that it is listed under Settings, then Connected Apps.

Is there an official Microsoft Ads MCP server for Gemini?
Yes. Microsoft Advertising runs its own MCP server with read-only access, and its setup guide has you register an Azure app with the Azure CLI before you add it to Gemini as a custom connector (checked 30 Sep 2026). PaidSync adds from Gemini's connector directory with a PaidSync sign-in, and its 156 Microsoft Ads tools read reports and make changes inside your existing campaigns.
Can Gemini create Microsoft Ads campaigns with PaidSync?
Yes, Search and Performance Max campaigns. Gemini can create them, copy a campaign, and add ad groups, keywords, responsive search ads and dynamic search ad targets, and each new campaign, ad group, keyword and ad starts paused unless you say otherwise.
