For a PPC agency, the best MCP use case today is repeatable read-only reporting across client workspaces and role-bounded platform permissions. An agency user can discover active integrations reachable through current workspace memberships and role-bounded platform Read permissions, select a workspace/platform/account and period, collect comparable evidence from Google Ads and Meta Ads, and preserve provenance for review. The connection does not replace account permissions, client approval, or a human strategist—and Adstudio's public MCP cannot change campaigns.
An agency operator often has access to many brands, business managers, and ad accounts. A prompt such as “How are my ads doing?” is underspecified and unsafe: it can invite the wrong account, a blended total, or a conclusion that hides platform differences. MCP should make scope explicit before analysis begins.
Use an opening prompt like:
“Run list_accounts and discover active workspace integrations reachable through my current workspace memberships and enabled per-platform Read permissions. Return platform, client/workspace label, account ID, account name, and currency. Do not query performance until I select one client and one or more accounts.”
Then pin the scope in the next call:
“Use only Client North's Google Ads account 1234567890 and Meta Ads account act_123. Compare the last complete calendar month with the prior month. Keep results separated by platform and account, and state any unavailable fields.”
If the system cannot honor that boundary, stop. A polished report is not useful if its account scope cannot be demonstrated.
For example, a weekly collection prompt can be:
“For the selected client accounts, return separate campaign tables for the last complete week: spend, impressions, clicks, conversions, conversion value, and CPA where available. Include source, account ID, currency, timezone/date assumptions, and freshness. Then list three changes from the prior complete week with the underlying rows.”
An anomaly prompt can be:
“Find campaigns whose spend changed by at least the threshold I provide while conversions moved in the opposite direction. Show daily evidence and label each statement as observed, calculated, or hypothesis. Do not recommend a budget change yet.”
The value is a consistent evidence request that a strategist can check—not an unsupported promise of hours saved.
Ad platforms are not interchangeable ledgers. Google Ads and Meta Ads can have different conversion events, attribution windows, timezones, currencies, delivery delays, and entity hierarchies. If a report says “CPA rose,” the client should be able to see which platform, account, date range, and field produced that statement.
Ask the AI to preserve provenance explicitly:
“For every reported metric, include platform, account ID, period, currency, source field, and whether the value came directly from the API or was calculated. Keep incompatible definitions out of a single total.”
That makes disagreements diagnosable. If the client sees a different total in Ads Manager, the team can compare assumptions instead of arguing over a mysterious number.
Adstudio's public MCP is a hosted OAuth service: one personal connection reaches every workspace its user belongs to, with availability bounded by role and enabled per-platform Read permission. list_accounts discovers active integrations, and each later call explicitly selects workspace, platform, and account before using bounded read tools. It currently supports Google Ads and Meta Ads. Its horizontal role is to help an authorized AI discover reachable workspace integrations and compare evidence across those channels without manual cross-account collection. It is not a general provider gateway: do not attribute TikTok Ads, OpenAI Ads, DV360, or other Adstudio integrations to this MCP surface. Google's platform reference also documents an official read-only Google Ads MCP server, which is vertical rather than cross-channel.
Agencies should still maintain client-level permission records and reporting templates. MCP does not decide whether a client authorized a report, fix a naming convention, or make unlike metrics comparable. For security controls, read read-only versus write MCP and MCP security.
Do not let a read-only reporting connection silently become a write path. The public MCP cannot pause campaigns, edit budgets, modify keywords, or publish creative. Keep recommendations in a review queue and execute any approved action through a controlled workflow with the client and account context visible.
Do not ask for a cross-client aggregate unless the client has authorized it and the result is genuinely needed. A single agency login is not a reason to mix brands. Do not describe a missing account as zero performance, and do not hide platform definitions behind one blended ROAS.
For client setup, see connecting ChatGPT or connecting Claude. For platform-specific evaluation, compare the Google Ads guide and Meta Ads guide.
MCP gives agencies a useful pattern for scoped, repeatable evidence collection: discover active integrations, explicitly select workspace/platform/account, query bounded periods, retain provenance, and have a strategist review the conclusion. Adstudio's current public connection supports that pattern for Google Ads and Meta Ads in read-only mode. The agency remains responsible for client consent, metric definitions, and every action taken afterward.
