Multi-Account & Agencies

Running several brands or a client roster through one connection: how accounts are addressed, how to avoid acting on the wrong one, and which tools exist for cross-account work.

How multiple accounts work

A connection reaches every account the authorised identity can already access. For Google Ads that includes everything under a manager (MCC); for Meta it is every ad account your Business Manager role covers.

One authorisation can expose many accounts — you do not connect each one separately
You name the account in the request, and the client passes it as a parameter
Accounts that do not appear are a permissions question on the platform side

Say which account you mean

The single most useful habit for agency work is naming the account in the first sentence. Ambiguity is where the wrong-account mistakes come from.

Tip

If you manage many accounts, start the conversation by asking which accounts are visible. It confirms the connection and gives the client the exact names to use.

Cross-account tools

Some tools are built to span accounts rather than run once per client, which is what makes a Monday-morning roster review practical.

Common questions

Do I need one MCP Ads account per client?

No. One account with the right connections reaches every ad account your identity can access, and you address them by name.

How do I stop it acting on the wrong client?

Name the account explicitly, and prefer read-only questions when working across many at once. Write tools take an account parameter, so an unnamed account is an ambiguity the client will usually ask you to resolve.

Does an MCC connection cover new accounts automatically?

Accounts added under the manager later are reachable by the same authorisation, because the grant follows the identity rather than a fixed list.

Can I give a team member access?

Team access is managed in your MCP Ads account rather than by sharing a connection. Platform-side roles still govern what any connection can reach.
