Short answer
If you advertise on one platform, use that platform’s official MCP server. Meta’s is free with read and write, Google’s is free and read-only. Beyond one platform it depends on your channel mix: PaidSync for LinkedIn, Adspirer for TikTok, Pipeboard for social-first Meta and Google, GoMarble if you want to self-host. Muze is the pick when your spend is Meta, Google and Amazon and you sell on Shopify, because it reaches all four through one OAuth connection, previews every write before it runs, and creates new campaigns paused.
What we compare on
Five things change the decision: how many platforms one connection reaches, whether the server can write as well as read, how much setup stands between you and the first useful answer, what happens before a write executes, and whether pricing and capability are published clearly enough to compare. Tool count is on every page because vendors publish it, but it is not a ranking. More endpoints means more calls an assistant can make, not better judgement about which one to make.
Every figure comes from the vendor’s own site or repository and was last verified on 2026-07-24. Where a vendor does not publish a number, the pages say so rather than estimating one.
Meta, Google, Amazon and Shopify in one connection
Muze runs from ChatGPT or Claude through a single OAuth login. Every write previews first and new campaigns are created paused.
