What marketing MCPs cost: plans, API units and pay-as-you-go

The server is rarely the expense. The subscription it needs, or the units it spends per question, usually is.

Costs people miss

Several calls per question: assistants often discover, then query, then refine.
Ad spend: a server that can edit campaigns, like Meta’s, can change what you spend.
Your assistant’s own plan: some connector features require a paid assistant plan.
Time: local servers that need Google Cloud setup cost an afternoon the first time.

How to keep it under control

Ahrefs lets admins set a monthly unit limit per MCP key. DataForSEO’s account panel has budget limits. Semrush shows your unit balance under Subscription info. Dance shows the price in the conversation and only continues with the amount you approved.

Prices change. We link each vendor’s pricing source from its profile and show the date we last checked.
