Google Connected Apps Platform: How to Integrate with Gemini

The Connected Apps Revolution: How to Integrate Your Services Directly Into Gemini and Search

If you are a developer or a product owner, you surely understand that the real battle for user attention is no longer happening only inside your application. Users are where they make decisions and perform actions – within AI tools like Gemini and search engines. Google recently launched the Connected Apps Platform, a game-changing platform that allows developers to make their capabilities accessible directly within these interfaces.

What is the Connected Apps Platform, really?

Instead of building complex, custom integrations for every platform, Google now offers a unified standard based on the Model Context Protocol (MCP). The idea is simple: you build an MCP server that exposes your tools and data, and Google takes care of making them accessible to users in Gemini and Google Search. Once the user approves the connection, they can perform actions in your service without leaving the chat or the search results page.

How does it work in practice?

The process is based on working with a remote MCP server. Here are the key steps you need to know:

•MCP Server Development: You set up a server that provides your Tools. The server must be accessible via HTTPS and capable of communicating in a standard JSON-RPC format.
•Local Testing: Before you rush to launch, Google provides the MCP Inspector, a tool that allows you to test your server locally, view payloads, and examine how your tools behave.
•Gemini Developer Mode: This is a critical step where you connect your server to a dedicated development environment within Gemini. Here, you can see in real-time how the model triggers your tools, check latency, and see how the interface looks to the end user.
•Registration and Approval: Through the Google Connected Console, you define your application details, verify domain ownership, and submit your application for Google's review.

Important points to keep in mind

It is important to understand that this is not an automatically "open door" for everyone. Google is rolling out access gradually (Preview), and even if you have a ready-made MCP server, it will not be available to all Google users until you pass the approval and publishing process in the console.

Additionally, you have full control over the user experience: you can choose whether your service will appear only in Gemini, only in Search, or in both. This allows you to tailor the integration to the specific value your service provides – whether it is quick information retrieval or performing complex actions.

Why is this important for you?

The ability to appear in Gemini is not just a matter of convenience, but of relevance. Users today expect their AI to be an "agent" that knows how to perform tasks. If your application is not there, you are losing your users to competitors who have already adopted this standard.

Developer Tip: Do not wait for the platform to open up to everyone. Start building your MCP server now, use the Developer Mode to fine-tune your tool schemas, and be ready the moment access expands.
