Creating a custom Model Context Protocol (MCP) client using Gemini 2.5 Pro provides an opportunity to design a highly adaptable and efficient communication solution. By combining a robust backend, a modern frontend, and advanced features such as contextual memory and voice response, you can develop a client tailored to your specific needs. This guide by All About AI outlines the essential steps, technologies, and best practices required to build a scalable and user-friendly MCP client.
Building an MCP Client
TL;DR Key Takeaways :
- Building a custom MCP client with Gemini 2.5 Pro enables a highly flexible and tailored communication solution, using modern technologies like Node.js for the backend and React with TypeScript for the frontend.
- Backend development focuses on establishing server connections, handling requests, and implementing APIs, while the frontend prioritizes creating an intuitive and responsive user interface with contextual memory integration.
- Contextual memory allows the client to store and recall conversation history, enhancing user experience by allowing follow-up queries without repeating prior context.
- Voice response functionality, powered by OpenAI’s text-to-speech model, improves accessibility and usability, especially for hands-free applications or users with accessibility needs.
- Custom features like email integration, advanced database support, and local deployment provide enhanced flexibility, scalability, and control over the client’s functionality and costs.
Getting Started: Laying the Foundation for Your MCP Client
The first step in building your MCP client is to establish a solid project foundation. This involves setting up both backend and frontend environments to ensure seamless integration and scalability. For a modern development approach, consider using the following technologies:
- Node.js: A powerful runtime environment for backend development, allowing efficient server-side logic and communication.
- React with TypeScript (TSX): A versatile framework for frontend development, offering type safety and a dynamic user interface (UI).
Begin by installing the necessary dependencies and configuring your development environment. Ensure that the client can communicate effectively with MCP servers by implementing appropriate protocols and tools. Proper setup at this stage will streamline the development process and minimize potential issues later.
Backend Development: Building the Core Infrastructure
The backend serves as the backbone of your MCP client, managing server-side logic and facilitating communication with MCP servers. To build a reliable backend, focus on the following tasks:
- Establishing server connections: Configure secure and efficient connections to MCP servers to handle data exchange.
- Developing server scripts: Write scripts to process incoming requests, generate responses, and manage server-side operations.
- Creating APIs: Design APIs to enable smooth communication between the backend and frontend components.
Troubleshooting is a critical aspect of backend development. Address connectivity issues, debug errors, and ensure consistent data flow to maintain the reliability of your client. Regular testing and monitoring will help identify and resolve potential bottlenecks.

Frontend Development: Crafting a User-Centric Interface
The frontend is the user-facing component of your MCP client, where interaction takes place. By using React and TypeScript, you can create a responsive and intuitive UI that enhances the user experience. Key areas to focus on include:
- Designing an adaptable UI: Ensure the interface is user-friendly and optimized for both web and mobile platforms.
- Integrating contextual memory: Enable the client to recall previous interactions, allowing users to ask follow-up questions seamlessly.
- Facilitating frontend-backend communication: Implement efficient data exchange mechanisms to ensure smooth interaction between components.
A well-designed frontend not only improves usability but also ensures that users can navigate and interact with the client effortlessly. Prioritize accessibility and responsiveness to cater to a diverse user base.
Enhancing Functionality with Advanced Features
To make your MCP client more versatile and user-friendly, consider integrating advanced features such as contextual memory and voice response. These enhancements can significantly improve the client’s functionality and user experience.
Contextual Memory:
This feature allows the client to store and recall conversation history, allowing users to continue discussions without repeating prior context. To implement contextual memory:
- Modify the backend to store conversation logs using a database or in-memory storage solutions.
- Update the frontend to retrieve and display relevant context during interactions, making sure coherent responses.
Voice Response:
Adding voice response functionality makes the client more accessible and convenient, particularly for hands-free applications. OpenAI’s text-to-speech (TTS) model is a reliable option for this purpose. To integrate voice response:
- Incorporate the TTS model into the backend to convert text responses into natural-sounding speech.
- Optimize responses for voice playback by summarizing lengthy outputs and adjusting tone for clarity.
These features not only enhance usability but also broaden the client’s appeal to a wider audience, including users with accessibility needs.
Customizing Your MCP Client for Specific Needs
One of the key advantages of building a custom MCP client is the ability to tailor it to your unique requirements. By incorporating additional features, you can expand the client’s capabilities and adapt it to evolving demands. Examples of custom features include:
- Email Integration: Enable the client to fetch, summarize, and send emails directly, streamlining communication tasks.
- Database Support: Add advanced memory handling and data management capabilities for more robust functionality.
- Local Deployment: Run the client locally to gain greater control over costs, security, and customization.
These enhancements allow you to create a solution that aligns closely with your goals, offering greater flexibility and control over communication processes.
Iterative Development and Continuous Improvement
Developing an MCP client is an iterative process that requires ongoing refinement to meet user expectations and technical demands. Common challenges include:
- Debugging server connections: Resolve connectivity issues to ensure reliable communication between components.
- Enhancing UI responsiveness: Optimize the frontend for a smoother and more intuitive user experience.
- Incorporating user feedback: Regularly gather and implement feedback to improve functionality and address user needs.
By adopting a cycle of testing, feedback, and iteration, you can ensure that your MCP client evolves into a robust and efficient solution. This approach allows you to address challenges proactively and adapt to changing requirements.
Final Thoughts
Building a custom MCP client with Gemini 2.5 Pro offers unparalleled flexibility and control over communication tasks. By integrating advanced features like contextual memory and voice response, you can create a powerful and user-friendly solution. Custom enhancements, such as email handling and database integration, further expand the client’s capabilities. Through careful planning, development, and iterative improvement, you can design a scalable, efficient, and tailored communication client that meets your specific needs.
