Meta has plugged Stripe into Muse, so payments can run through a developer's product inside the agent. That comes with Muse Connectors, a platform where developers and businesses submit their own integrations; Notion, Granola and others are listed as available.
The pitch to developers is short: "Reach new customers and give existing ones more ways to use your product." Muse, the agent Meta gave its own file system, terminal and browser, also opened in Canada.
Meta didn't say how submitted Connectors get reviewed, or what a developer pays to sit on the platform.
