How agencies use Marketer MCP across client accounts

Agency media buyers juggle 5, 10, or 20 client budgets simultaneously. Each has different channel mixes, pacing requirements, and reporting expectations. Doing this in spreadsheets is how budgets get missed and client trust erodes.

One connection, every client

Marketer MCP is a single endpoint. Your team connects once and can run Budget Buddy (and future tools) for any client by passing different budget and spend data per request. No per-client setup. No additional logins.

Namespaced isolation

Every tool execution is namespaced. Client A's spend data never crosses into Client B's request. Auth tokens can be scoped per team or per client, giving you control over who accesses what.

Real-time pacing across the book

Instead of checking each platform for each client, agencies can automate pacing checks through their AI workflow. Ask your assistant "which clients are over-pacing this week?" and it calls Budget Buddy for each account, returning a consolidated view of risk.

Scaling QA without scaling headcount

As the tool registry grows — Attribution QA, Creative QA, Campaign Flighting — agencies get operational leverage. The same team can QA more campaigns, catch more UTM errors, and validate more creatives without adding heads. That is margin improvement through better tooling.
