Is there a free ads MCP server?

Yes, several. Meta's official server is free during its open beta, Google's official server is free and read-only, and Muze has a permanently free tier of 25 read-only tool calls a month.

Does Muze charge for the AI model?

No. You bring your own AI client, so you are never billed by us for model tokens. You pay whatever ChatGPT, Claude or Cursor already costs you.

What counts as a tool call?

Each individual tool the assistant invokes against your accounts. One question in chat can trigger several calls, especially if it spans more than one platform.

Do I need a credit card for the free tier?

No. The free plan needs no card.

Does anyone in this category charge a percentage of ad spend?

Agencies commonly do. Muze does not, and we think no software in this category should. You pay a flat monthly fee and your ad budget goes to the platforms directly.

How much does an ads MCP server cost?

Short answer

Between nothing and about $100 a month for the server itself. Meta's and Google's official ad MCP servers are free. Muze is free for 25 read-only tool calls a month, $29 a month for 400 calls with confirm-gated writes, and $99 a month for 2,500 calls. On top of that you pay for the AI client you already use, and you keep paying the ad platforms directly. No ads MCP server should be taking a percentage of your ad spend.

Three separate costs, and only one of them is the server

The server subscription. This is the number people compare, and it is the smallest of the three.
Your AI client. ChatGPT, Claude, Cursor or whatever you already pay for. You bring your own model, so a well-built MCP server does not bill you again for tokens.
The ad spend. Paid to Meta, Google and Amazon on your own cards, exactly as it is now. Muze never holds or touches ad budget.

The unit that actually matters is the tool call

Plans are metered in tool calls, not questions, and one question is often several calls. "Summarize last week across all four platforms" is not one call. It is a handful of reads, and possibly a few more if the assistant decides to check something.

Read-heavy analysis burns an allowance faster than people expect, which is why a free tier is for evaluating rather than operating. Budget by workflow: a weekly cross-platform review costs a predictable number of calls, and a daily one costs roughly five times that.

Why percentage-of-spend pricing is a conflict of interest

Agencies and tools that take a cut of ad spend get paid more when you spend more. That is a straightforward misalignment, and it does not become acceptable because the percentage is small.

Muze charges a flat monthly subscription and never a share of spend. Your budget is yours. Full plan detail is on the pricing page.

Working out what you need

Evaluating, or reporting only: free, or one of the official first-party servers.
One operator running one or two platforms with real actions: the $29 tier.
An agency or a team across multiple accounts with frequent workflows: the $99 tier.
