Google opens Connected Apps to developers for Search and Gemini

Developers can connect an app through a cloud-hosted MCP server or through Android MCP using the AppFunctions APIs.[1] The cloud-hosted route reaches Search and Gemini users on web, Android and iOS, according to The Keyword.[2] The Android MCP route uses AppFunctions but is limited to Gemini on Android.[2] Teams deciding between the routes should weigh which Google surfaces and devices they want to support; the two options do not offer the same reach.[2] Google says developers can track traffic, latency and error rates after an app goes live.[1]

Google reviews and tests every app before publication.[3] Developers must list at least three tasks their app can perform for users.[2] If an app requires sign-in, developers must provide Google with test accounts containing sample data; apps Google cannot fully test may be rejected.[3] Google’s policy bars third-party advertising and promotional material in Connected Apps, while allowing an app’s own brand elements, and requires each app to offer standalone value without advertising.[2] Policy violations can lead to rejection, suspension or removal of an app, or suspension or termination of its developer’s account.[2]

Google says it has launched more than 50 Connected Apps across Search and Gemini, covering areas including productivity, event ticketing, health and fitness.[1] Adobe, Experian, Localiza and Peloton integrations are live in Gemini, with Google planning to bring them to Search in the coming weeks.[1] Google says a new Calm integration will be available across Search and Gemini.[1] In Search, Connected Apps are currently available in AI Mode in the United States and in English.[4] Users can name an app in an AI Mode request or select one from a list, and Google may default to the last app used for a particular task.[4]
