We benchmark all the GTM APIs and we put the results on our website. Our MCP server is open to anyone, with no key. list_apis lists the GTM APIs on it, and search_plans finds their plans by API, provider or price.

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Datacircle to help me.

We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
