To connect Microsoft Ads (Bing Ads) to Claude, add PaidSync from Claude's connector directory, sign in, and ask Claude to connect your Microsoft Advertising account. PaidSync is our pick because it gives Claude 133 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 does not create Microsoft Ads campaigns. Setup takes about 2 minutes, and it is free for 15 tasks with no credit card.
This is the route through Claude's connector directory. No API key is needed, because Claude connects with a PaidSync sign-in (OAuth).
Before you start
Open PaidSync in the Claude connector directory and click Connect. Or, in claude.ai or the Claude Desktop app, open Customize, then Connectors, click + next to Connectors, search PaidSync, and click Connect.
Sign in with your PaidSync login. That OAuth sign-in is what lets Claude apply changes. Connectors work on every Claude plan, including Free.
Using Claude Code instead? Run claude mcp add --transport http paidsync https://mcp.paidsync.ai/mcp, then type /mcp inside a session to sign in.
On a client with no directory, add PaidSync as a custom connector with the server URL instead (on a Team or Enterprise plan, only an Owner can add one):
https://mcp.paidsync.ai/mcpSave it, then sign in with your PaidSync login when Claude asks.
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 Claude to manage your ad accounts via PaidSync. Press Approve and Claude shows PaidSync as 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.
In any chat, ask: "Connect my Microsoft Ads." Claude 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." Claude 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."
PaidSync has 133 Microsoft Ads tools. They read reports and change existing campaigns, including new ad groups, keywords and ads. They do not create campaigns.
What PaidSync can do
What PaidSync cannot do
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.
get_ms_performance, which returns spend, clicks, impressions, conversions, revenue, CTR, average CPC and ROAS for each campaign.get_ms_search_query_performance, then add_ms_negative_keywords, which previews by default and sends nothing until you approve.pause_ms_campaign. Ask for enable_ms_campaign to turn it back on.update_ms_campaign_budget, which previews by default and, once applied, reads the new budget back from Microsoft to check it.create_ms_adgroup, add_ms_keywords and add_ms_responsive_search_ad. Each one previews by default, and the new ad group, keywords and ad start paused.It makes changes, not just reports. 133 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 Claude, 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, 610+ tools through one endpoint, so Claude can compare Microsoft and Google results in the same chat.
This guide is for the Claude app. In Claude Code the same PaidSync connection is one command:
claude mcp add --transport http paidsync https://mcp.paidsync.ai/mcpStart a session, type /mcp, pick paidsync, and sign in with your PaidSync login in the browser window that opens. Claude Code stores the OAuth token for you. No key is pasted anywhere. The Claude Code setup page covers the shared .mcp.json for teams and a headless audit run.
list_ms_accounts, then set_active_microsoft_account, and every Microsoft Ads request after that goes to the account you picked. Switching uses none of your tasks.paidsync_context with include_tools:['microsoft_ads']. It returns your connected platforms and the Microsoft Ads tool names, and Claude then runs them through paidsync_exec. If PaidSync is missing from Claude altogether, check that it shows as connected under Customize, then Connectors.Add PaidSync from Claude's connector directory and click Connect, or in Claude open Customize, then Connectors, search PaidSync and click Connect. Sign in to PaidSync and press Approve, then ask Claude to connect your Microsoft Ads account and list your accounts. You need no API key and no Microsoft developer token. Full steps are above.
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 Claude as a custom connector (checked 30 Sep 2026). PaidSync adds from Claude's connector directory with a PaidSync sign-in, and its 133 Microsoft Ads tools read reports and make changes inside your existing campaigns.
No. PaidSync works inside campaigns that already exist. Claude can add ad groups, keywords, responsive search ads and dynamic search ad targets to them, and each new ad group, keyword and ad starts paused unless you say otherwise. Create the campaign itself in Microsoft Advertising, or import it there from Google Ads.
Campaign performance with spend, clicks, impressions, conversions, revenue, CTR, average CPC and ROAS, plus ad group, keyword, search term, conversion, location and audience reports. Claude can also list your campaigns, ad groups, ads, keywords and negative keywords.
No. PaidSync connects through Microsoft's own sign-in and consent screen and supplies the developer token on its side, so you never register an Azure app or paste a key.
Free for 15 tasks with no credit card. Pro is from $99 a month for 600 tasks, Team is from $249 a month for 5 seats and 6,000 tasks, and Done For You is custom. See pricing.
Yes. PaidSync is one endpoint, https://mcp.paidsync.ai/mcp, with OAuth sign-in, and the same login works in Claude, ChatGPT and Claude Code. Three Microsoft tools, the two offline conversion uploads and the UET tag key read, run in Claude but are withheld in ChatGPT, because they carry hashed customer data or an access key.
