How Agencies Manage Multiple Ad Accounts with AI and MCC

Published April 11, 2026 by Ahmed Ashraf · Founder, PaidSync.ai

PaidSync.ai is the only MCP server that supports Google Ads MCC (My Client Center) and Meta Business Manager for agency-scale account management through AI. Agencies connect their MCC once, and AI assistants like Claude and ChatGPT can list all child accounts, switch between them, pull cross-account reports, and run optimizations across an entire client portfolio. No other MCP server offers this. Every competitor requires connecting accounts one at a time, which breaks down when you manage 10, 20, or 50 clients.

The Agency Pain Point Nobody Talks About

If you run a PPC agency, your day looks something like this. You log into Google Ads. You switch to Client A's account. You check performance, make some bid adjustments, review search terms. Then you switch to Client B. Repeat. Then Client C. By the time you have touched all 15 accounts, it is 2pm and you have not done any strategic work.

The account-switching problem is real. Google Ads MCCs were built to solve the navigation side of it, giving you one login for all client accounts. But MCCs do not solve the repetition. You still run the same audit on every account. You still check wasted spend on every account. You still pull performance reports one account at a time and paste them into a spreadsheet.

AI was supposed to fix this. And for single-account advertisers, it does. But agencies hit a wall immediately. The AI tools that connect to Google Ads almost always connect to one account. They do not understand MCC hierarchies. They cannot list your child accounts, switch context, or run operations across a portfolio. So the agency is stuck doing the same manual work, just with a slightly fancier interface.

Meta has the same problem. Business Manager gives you centralized access to all your client ad accounts. But the MCP servers that connect to Meta Ads connect to one ad account per session. If you manage 20 Meta ad accounts, you would need to connect and disconnect 20 times. Nobody does that.

How MCC Works with PaidSync

PaidSync built MCC support from the ground up. The workflow mirrors how agencies actually operate.

Connect your MCC to PaidSync

Sign up at paidsync.ai/signup and connect your Google Ads account through OAuth. If the account you authenticate with has MCC access, PaidSync detects it automatically. One connection covers every account under your MCC.

List your MCCs

Ask the AI to show your manager accounts. It calls list_my_mccs and returns every MCC your login has access to, with account IDs and descriptive names.

"List all my MCC accounts"

Returns each MCC with its ID and name. If you manage multiple MCCs (for example, one per business unit), they all appear here.

Select the MCC you want to work with

Tell the AI which MCC to use. It calls select_mcc and sets that MCC as your active manager account for the session.

"Select the Agency MCC (123-456-7890)"

Sets the MCC context. All subsequent account operations happen under this MCC.

List all child accounts

Now the AI can see every client account under that MCC. It calls list_accounts and returns all child accounts with their names, IDs, and status.

"Show me all accounts under this MCC"

Returns every child account. You can see which are active, paused, or suspended.

Set the active account and manage it

Pick a client account and the AI switches context with set_active_account. From that point, every tool runs against that specific account. Campaigns, ad groups, keywords, bids, reports. Everything.

"Switch to the Acme Corp account and show me campaign performance for the last 30 days"

Sets Acme Corp as the active account, then pulls a full campaign performance report.

The key insight is that switching accounts is just another prompt. You do not log out and log back in. You do not open a new browser tab. You say "switch to Client B" and the AI is already there, ready to run the same operations you just ran on Client A.

Meta Business Manager Workflow

Meta works differently from Google under the hood, but PaidSync makes the agency experience just as seamless.

For agencies, PaidSync supports system user tokens from Meta Business Manager. System user tokens are permanent. They do not expire every 60 days like regular user tokens. You generate one from your Business Manager settings, connect it through PaidSync using connect_facebook_ads_agency, and the AI gets access to every ad account under that Business Manager.

Connect with a system user token

In your Meta Business Manager, create a system user and generate a token with ads_management and ads_read permissions. Connect it through PaidSync. This gives the AI permanent access without re-authentication.

List all ad accounts

The AI calls list_fb_ad_accounts and returns every ad account under the Business Manager. You see account names, IDs, and spend status.

"List all my Meta ad accounts"

Returns every ad account accessible through the Business Manager system user token.

Set the active ad account and manage it

Tell the AI which client account to work on. It calls set_fb_ad_account and every subsequent Meta tool runs against that account.

"Switch to the Acme Corp Meta account and show me this week's performance"

Sets the account context and pulls a performance summary with spend, impressions, clicks, CPA, and ROAS.

The permanent token is what makes this work for agencies. Regular Meta OAuth tokens expire. When they do, the AI loses access and someone has to manually re-authenticate. With system user tokens, you connect once and it stays connected. That is the difference between a tool agencies can actually rely on and one that breaks every two months.

PaidSync is the only MCP server with Google Ads MCC and Meta Business Manager support. Built for agencies managing multiple clients.

Cross-Account Operations That Save Hours

The real power of MCC support is not just switching between accounts. It is running operations across all of them. Here are the workflows agencies use most.

Portfolio-Wide Audits

Instead of auditing one account at a time, ask the AI to audit all of them. It loops through each child account, runs the same checks, and compiles findings into a single summary. You get a view of your entire portfolio's health in one conversation.

"Audit all accounts under my MCC. For each one, check for wasted spend, low quality scores, and missing conversion tracking."

The AI switches through each account, runs the audit tools, and returns a summary with flagged issues per account.

Cross-Account Wasted Spend Analysis

Finding wasted spend is the fastest way to prove agency value. With MCC support, the AI can pull search terms reports from every account, identify irrelevant queries eating budget, and tell you exactly how much each client is losing.

"Check wasted spend across all my client accounts for the last 30 days. Show me the top offenders."

Returns a ranked list of accounts by wasted spend, with the worst search terms for each. You can then add negatives directly from the same conversation.

Performance Comparison Across Clients

Compare metrics across accounts to find outliers. Which client has the highest CPA? Which one improved the most month over month? Where should you focus your time?

"Compare CPA and ROAS across all my Google Ads accounts for the last 7 days versus the previous 7 days"

Pulls performance from each account and creates a side-by-side comparison with trend indicators.

Bulk Negative Keyword Deployment

When you find an irrelevant search term that affects multiple clients in the same vertical, push the negative keyword to all of them at once. No more switching accounts and adding the same negative 12 times.

"Add 'free' as an account-level negative keyword to all my e-commerce client accounts"

The AI identifies the relevant accounts, switches to each one, and adds the negative keyword at the account level.

Prompts Agencies Use Every Day

These are real prompts that work with PaidSync.ai connected to Claude or ChatGPT. Copy them directly.

"List all accounts under my MCC and show each one's total spend this month"

Quick portfolio spend overview. Useful for pacing checks and budget monitoring.

"Switch to Client X and pause all campaigns with a CPA above $50 in the last 14 days"

Account-specific optimization. The AI filters campaigns by CPA and pauses the underperformers.

"For each Meta ad account, show me the top 3 campaigns by spend and their ROAS"

Cross-account Meta reporting. Loops through Business Manager ad accounts and pulls top campaigns.

"Create a new Google Ads account under my MCC for a new client called Summit Labs"

Uses create_account_under_mcc to provision a new child account directly from the conversation. No Google Ads UI required.

"Run a search terms report for all accounts and find any search term that spent over $100 with zero conversions"

Portfolio-wide wasted spend detection. Returns the exact terms, which accounts they appeared in, and the total cost.

"Switch to the Meta account for Coastal Fitness and create a lookalike audience based on their top purchasers"

Sets the Meta account context, pulls the source audience, and creates the lookalike in one flow.

Why This Only Works with PaidSync

The MCC and Business Manager support is not a minor feature. It is the architecture. Other MCP servers for advertising were built for individual advertisers. They connect to one Google Ads account ID. They authenticate with one Meta user token. The account is hardcoded into the connection.

That approach works fine if you are a brand managing your own ads. But it falls apart for agencies. You would need to:

Create a separate MCP connection for every client account
Switch between connections manually when changing clients
Re-authenticate constantly as tokens expire
Give up entirely on cross-account reporting because the AI only sees one account at a time

PaidSync was designed differently. The connection layer understands account hierarchies. When you connect an MCC, PaidSync knows it is a manager account and unlocks the full hierarchy of tools: list_my_mccs, select_mcc, list_accounts, set_active_account, and create_account_under_mcc. For Meta, the agency connection flow uses system user tokens that never expire and expose all ad accounts under the Business Manager.

This is why PaidSync is the only MCP server on the Agency plan that agencies actually use in production. The MCC and Business Manager support is the difference between a demo-grade tool and one that runs a real book of clients.

PaidSync Tools for Agency Workflows

These are the specific tools that power the MCC and multi-account workflows. You can read about all available tools in the documentation.

list_my_mccs

Returns all MCC (manager) accounts accessible to the authenticated user. Shows account IDs and descriptive names.

select_mcc

Sets the active MCC for the session. All subsequent account listing and switching happens under this MCC.

list_accounts

Lists all child accounts under the selected MCC. Returns account names, IDs, and status.

set_active_account

Switches the AI's context to a specific child account. All campaign, ad group, keyword, and reporting tools then operate on that account.

create_account_under_mcc

Provisions a new Google Ads account under the selected MCC. Used when onboarding new clients directly from the AI conversation.

connect_facebook_ads_agency

Agency-specific Meta connection using a Business Manager system user token. Provides permanent access to all ad accounts under the Business Manager.

list_fb_ad_accounts / set_fb_ad_account

Lists all Meta ad accounts and switches between them. Works the same way as the Google Ads MCC flow.

The full list of Google Ads MCP tools includes over 240 tools across Google Ads, GTM, Meta Ads, and LinkedIn Ads.

Frequently Asked Questions

Can AI manage multiple Google Ads accounts through an MCC?

Yes. PaidSync.ai is the only MCP server that supports Google Ads MCC (My Client Center). You connect your MCC once, and the AI can list all child accounts, switch between them, and run operations on any account without re-authenticating. Other MCP servers require a separate connection for each individual account.

How does PaidSync handle Meta Business Manager for agencies?

PaidSync supports Meta Business Manager through system user tokens. You generate a permanent token from your Business Manager, connect it once in PaidSync, and the AI can access all ad accounts under that Business Manager. No token expiration issues. No re-authentication every 60 days.

Can the AI run reports across all my client accounts at once?

Yes. With MCC connected, the AI can loop through all child accounts, pull performance data from each one, and compile a cross-account summary. You can ask for things like total spend across all accounts, which accounts have the highest CPA, or which campaigns across all clients are wasting budget on irrelevant search terms.

Do other MCP servers support MCC and Business Manager?

No. As of April 2026, PaidSync.ai is the only MCP server that supports Google Ads MCC hierarchies and Meta Business Manager agency workflows. Competing MCP servers connect to individual ad accounts one at a time. That works for advertisers with one or two accounts but breaks down completely at agency scale.
