MCP Learning Series - Part 3

-

 


In this blog, lets see how to add news MCP server and add it to the AI Client like Claude Desktop.

Refer to the code base for the new MCP server using Google News.

Start the MCP server is debug mode as $ mcp dev <news_server.py>


Click on the URL to open the MCP Inspector and look at the "Tools" section.


We added 2 tools:

1) Search News

2) Get Top Headlines



Now that the news MCP Server tool is working as expected. Lets add to Claude Desktop.

Open Claude Desktop and Settings

Click on "Developer"


Click on "Edit Config"


This open the "claude_desktop_config.json" file

claude_desktop_config is a configuration file used by Claude Desktop (the local desktop app from Anthropic). It controls how the desktop client behaves, including:

  • which model it uses

  • how it connects to the Claude API

  • what tools or plugins are enabled

  • local preferences for the desktop environment

  • developer‑specific overrides (for Claude Code, tool access, etc.)

It is a JSON file and we create a key value pair "mcpServers"

"mcpServers": {
    "news-server":{
     
    }

"mcpServers": {
    "news-server":{
      "command": "",
      "args": ""
    },


Command refers to how do you want to start the MCP Server program. 
Either using $ python <server.py> or $ uv run <server.py>

Final declaration:

"mcpServers": {
    "news-server":{
      "command": "uv.exe",
      "args": [
        "--directory",
        "C:\\news-server",
        "run",
        "main.py"
      ]
    }

Save the file and Restart the "Claude Desktop"

Now, we can see the "news-server" is running.


Let's test with the prompt to see if our Claude uses our new tools or not?



That's it. Simple right :)

                                                                      In this blog we will see how to build a simple agent without using any LLM model. Simple flow of an agent: Agent takes input -> Based on the input, it decides which tool to use -> Performs operation and send the output back to the user. An AI agent framework is  a set of tools, libraries, and structures that simplifies building, deploying, and managing autonomous AI agents. But, here we are going to build an agent without using any framework and LLM's. Agent functionality is to perform "Addition" and "Subtraction". Agent uses 2 python functions (Tools) to perform addition and subtraction operations. Finally, it send the output to the user. We are going to implement the above discussed functionality vi...

                                                                   In this blog, will how to create a simple agent using AI framework like Langchain with a simple LLM model  gpt-4o-mini. from langchain_openai import ChatOpenAI from langchain_core . tools import tool import os # Creating a tool @ tool def add_numbers ( x : int , y : int ) -> int :     "Add two numbers"     return x + y @tool is a decorator to define a tool. This is a simple tool to add 2 numbers. The below line creates a Langchain LLM wrapper around on the OpenAI chat mode 'gpt-4o-mini' # Binding the tool to a model llm = ChatOpenAI( model = "gpt-4o-mini" ).bind_tools([add_numbers]) response = llm .invoke( "What is 5 + 7?" ) When we print response, is the expected outcome? Is it 12. NO...

S3 - Directory Bucket

  Directory buckets organize data hierarchically into directories as opposed to the flat storage structure of general purpose buckets. There aren't prefix limits for directory buckets, and individual directories can scale horizontally. Directory buckets support bucket creation in the following bucket location types : Availability Zone or Local Zone. For low latency use cases, you can create a directory bucket in a single Availability Zone to store data. Amazon S3 Express One Zone is a high-performance, single-zone Amazon S3 storage class that is purpose-built to deliver consistent, single-digit millisecond data access for your most latency-sensitive applications.  S3 Express One Zone is the lowest latency cloud-object storage class available today, with data access speeds up to 10x faster and with request costs 50 percent lower than S3 Standard. With S3 Express One Zone, your data is redundantly stored on multiple devices within a single Availability Zone.   You can ac...
