Building an Agentic Application for Real Estate Analytics

Introduction

Searching for your new house often requires an understanding of price trends in your desired neighborhood. Instead of navigating through complex charts and dropdowns, imagine a more intuitive approach: simply asking, "Show me the price evolution in Manchester for the last 10 years." This vision is becoming a reality with Agentic applications, which utilize Large Language Models (LLMs) to provide insightful, real-time analytics at your fingertips. In this blog post, we will guide you through creating a customizable analytics dashboard tailored to the UK real estate market using MCP Server and CopilotKit.

Components of the Agentic Application

At the foundation of any agentic application is the Large Language Model (LLM), which serves as the brain of the application. This model interprets user prompts, understands the context, generates appropriate responses, and decides which actions to take. To ensure a fluid and responsive experience, using a capable LLM with rapid performance and a sufficiently large context window is crucial. Given that agentic applications often handle intricate prompts and interact with various external tools, efficient processing of evolving context and data retrieval is essential for delivering a natural user experience. For our application, we utilize the Claude Sonnet 3.7 model from Anthropic, noted for its high performance in interaction scenarios and adherence to domain-specific rules.

Next, we integrate the MCP Server, which allows our agentic application to analyze UK real estate market data through custom dashboards. Although the data may be publicly available, it is vital to differentiate between what the LLM has learned during training and real-time data access for accuracy. The Model Context Protocol (MCP) server facilitates secure two-way connections between the application and data sources, ensuring that the LLM can accurately fetch and process live data. By employing MCP server, we provide our application the ability to execute SQL queries dynamically, enhancing its functionality and reliability.

Lastly, we incorporate CopilotKit, a user interface framework specifically designed to simplify the development of these intelligent applications. CopilotKit abstracts various complexities, offering built-in support for chat interfaces, easy connections to multiple LLMs, and automated management of tool calls based on user interactions. Together, these components create a cohesive, powerful agentic application.

Building the Agentic Application

To construct this agentic application, we will follow a step-by-step approach. The first step involves initializing a new React application integrated with the CopilotKit framework. By running the command and following the obtained prompts, our application will be set up to utilize MCP directly. We ensure that during this initialization, we select the MCP option to establish the correct infrastructure.

Once our application framework is established, we then focus on incorporating our desired LLM. While CopilotKit defaults to OpenAI's models, it allows for configuration changes. We will replace the current model with the Anthropic adapter tailored to use the Claude Sonnet 3.7 model. This configuration should be implemented in the designated API route file, ensuring that the environment is also equipped with the necessary API key for secure access.

Following this, we proceed to deploy the MCP Server to facilitate the querying process. This can be set up locally or remotely, depending on preferences. Utilizing a preconfigured repository allows us to establish connections to the database easily. After setting up the necessary environment variables for host, user, and security parameters, we initialize the MCP Server using command line tools that expose it to the application. This action positions the application for real-time data interaction.

Conclusion

In this blog post, we've outlined the development of an agentic application leveraging MCP Server and CopilotKit, showcasing how such applications can revolutionize user interactions with data. The combination of LLMs, dynamic querying, and intuitive UI frameworks enables users to gain deeper insights and enhance decision-making processes in real estate analysis. As more businesses adopt these technologies, the potential for interactive applications will continue to grow, paving the way for more intelligent and user-centered analytics solutions.
