This is how to set device bid adjustments in Microsoft Ads with AI: connect your Microsoft Ads account to PaidSync.ai, then ask Claude to set device bid adjustments for a campaign, as the complete set of three that Microsoft requires. All three percentages are required together, and the change previews first.
Device bids need all three rows or none. The tool reads the current set and then writes the whole set:
get_ms_campaign_segmented_performance shows results by device so the adjustment is based on data.set_ms_device_bid_adjustments sets the multipliers for computers, smartphones and tablets together, adding or updating as needed.get_ms_campaign_segmented_performance only reads your account. set_ms_device_bid_adjustments changes it. Claude calls these to set device bid adjustments.
| Tool | What it does |
|---|---|
| get_ms_campaign_segmented_performance | Shows results by device |
| set_ms_device_bid_adjustments | Applies the set after the preview |
Microsoft creates nothing if the three are not supplied together, so a partial request would silently do nothing. The tool therefore asks for all three percentages. Setting them at ad group level overrides the campaign for that ad group.
These steps use Claude to set device bid adjustments in Microsoft Ads. In the ChatGPT app PaidSync.ai is report-only for Microsoft Ads, so the change itself runs in Claude or another MCP client.
Sign up at paidsync.ai, then connect Microsoft Ads on Microsoft's own sign-in screen. Use a Microsoft login that can reach the account where you want to set device bid adjustments.
Install PaidSync.ai from Claude's connector directory and sign in. Ask "list my Microsoft Ads accounts" and select the account to set device bid adjustments in.
Ask for results by device over a range long enough to have volume.
Pick a percentage for computers, smartphones and tablets.
Read the dry run and confirm.
Re-run the device split after a few weeks and compare cost per conversion for each device.
