You can absolutely work with several ad accounts when using HYPD inside Claude — here is the recommended setup.

Step 1: Make the accounts visible to Claude

In HYPD, select which accounts are accessible under Ad Platforms → Manage Google Ads accounts. Only toggled-on accounts are visible to Claude.

Step 2: Use Claude Projects with account IDs

Create a Project in Claude and put the ad account ID(s) in the project instructions. Claude matches accounts by account ID, not by name, so IDs are what count.

• To compare several accounts: list all their IDs in one project's instructions.

• To keep accounts separate: use one project per account so each account's chat history stays isolated.
