MCP Integration: How Brave Search and Claude Desktop Enhance AI Agentic Assistant Capabilities

Introduction to MCP Agentic AI

The Model Context Protocol (MCP) has revolutionized how AI assistants interact with external data sources, offering smooth integration with tools, repositories, and local or cloud-based datasets. Introduced by Anthropic in late 2024, MCP enables AI to go beyond its traditional constraints, making it more proactive, contextual, and integrated into our workflows. This article focuses on setting up the Brave Search MCP plugin for Claude Desktop to strengthen your AI assistant with advanced web search capabilities. Whether you are a developer or a casual user, this guide will help you integrate this tool to use AI’s full potential. This is a continuation of the article that Rick recently wrote on Setting up Claude Filesystem MCP, but it is a standalone article. First, we’ll explore an in-depth discussion of MCP, followed by practical hands-on use case that show the Brave search connector with the Claude client.

Their latest project, Meeting Buddy, was giving them a bit of a headache.***Rick:**Sipping his coffee “You know, Chris, the file drop synchronization just is not working as expected. The UI is not updating when new files are added.”Chris:“Yeah, I noticed that. It is like the UI is oblivious to the new markdown files we generate during meetings.”Rick:“Exactly! We need a way to have the UI respond in real-time as files are added or removed from the directory.”**Chris:**Grinning “Sounds like a job for the watchdog library and a bit of Streamlit magic!”Rick:“Agreed. Let us break it down and build a simple prototype that listens to a directory and updates the UI accordingly.”

They clinked their coffee mugs together, ready to embark on another coding adventure.

What is Microservice Architecture

What is Microservice Architecture?

Rick HightowerEngineering Consultant focused on AI

November 27, 2015

Microservice architecture is a method of developing software systems. Its focus is building small, reusable, scalable services. Applying Microservices becomes very important when you have to create services for polyglot devices: wearables, Internet of Things (IOT), mobile, desktop, and web. The trend towards providing services for rich, native mobile application and web applications started the trend towards Microservices adoption. This is one reason why microservices lean heavily on web technologies like HTTP/REST/WebSocket with JSON,Message Pack, and their ilk. The web technologies provide a low barrier to entry and least common denominator to communication.

A Roundhouse Kick into Streamlit Form Validation

Amid the rhythmic thuds of gloves hitting pads, Rick and Chris were immersed in their kickboxing class. Between combos, they exchanged thoughts—not just on perfecting their strikes but also on coding challenges. As they caught their breath, the conversation shifted to Streamlit and the importance of form validation.

Rick: Panting “You know, Chris, it’s like the saying ‘garbage in, garbage out.’ If I don’t validate the data properly in my Streamlit app, I can’t expect good results. I need to guard the gate and make sure only clean data gets through.”
