About MCP

What is MCP: Seamless Model Interactions, Developer-Friendly Power?

MCP (Model Context Protocol) is a standardized framework developed by Anthropic to enable Large Language Models (LLMs) to seamlessly interact with external tools, functions, and data sources. By providing a unified interface, MCP allows models to dynamically request real-time information, execute actions in connected systems, access specialized knowledge bases, and integrate with diverse APIs and services. This protocol acts as a "universal hub" for model interactions, ensuring compatibility across different platforms and services.

How to Use MCP: Seamless Model Interactions, Developer-Friendly Power?

To leverage MCP, developers first set up an MCP server using official SDKs (e.g., Python or TypeScript). Here's a simplified workflow:

Create a project directory and install the MCP SDK via package managers like npm.
Define tools, resources (e.g., databases, files), and prompts in your server configuration.
Configure the MCP server in your development environment (e.g., Cursor IDE) by specifying the server path and command.
Test interactions by invoking tools through standardized API calls, either locally via STDIO or remotely via Server-Sent Events (SSE).

MCP Features

Key Features of MCP: Seamless Model Interactions, Developer-Friendly Power?

Standardized Integration: Reduces API fragmentation by enforcing consistent communication patterns.
Modular Components: Separates tools, resources, and prompts for flexible, reusable workflows.
Transport Flexibility: Supports both local STDIO and remote SSE for scalable deployments.
Vendor-Neutral Ecosystem: Each company maintains its own MCP server, ensuring stability and reducing dependency risks.

Use Cases of MCP: Seamless Model Interactions, Developer-Friendly Power?

Common applications include:

Real-time data fetching for dynamic model responses.
Multi-model collaboration across different service providers.
Automated file processing and analysis pipelines.
Secure integration with proprietary or third-party APIs.

MCP FAQ

FAQ: Seamless Model Interactions, Developer-Friendly Power?

Is MCP compatible with all LLMs?: Yes, as long as models can communicate via the protocol's defined interfaces.
How does remote communication work?: Uses Server-Sent Events (SSE) for bidirectional data streaming between servers and clients.
Can I extend MCP with custom tools?: Yes—developers define tools using the SDK, enabling tailored functionality without modifying core protocol logic.
What happens if a tool fails?: Error handling is managed at the server level, with status codes and logging provided for debugging.
Where can I find community support?: Explore documentation and resources at MCP Official Docs and developer forums.

MCP (Model Context Protocol)

by Gaurav Kabra

The Model Context Protocol (MCP) is a standardized way, introduced by Anthropic, for LLMs to interact with external tools and functions and injecting context in LLMs. It allows models to:

Request real-time information
Execute actions in external systems
Access specialized knowledge
Interact with APIs and services

→ Agents → MCP The 2nd figure is like this:

So we improve and get to the 3rd figure, which is similar to: The MCP is similar to USB hub in above picture. Due to it being a standard, changes become in a standard way. So less chances of API breaking since each MCP server is now being maintained by individual companies (Yahoo or Google etc.) and we just integrate with them.

An MCP server will expose 3 things:

Tool: Resource: includes knowledge base, DB, files etc. Prompt:

You can refer this for above images.

Setup From Scratch

mkdir mcpserver
npm init
npm install @modelcontextprotocol/sdk

See this for official documentation.

Now in Cursor IDE, click on Settings cog -> MCP. Create the file mcp.json and put below code:

{
    "mcpServers": {
        "Gaurav Kabra's MCP Server": {
        "command": "node",
        "args": ["/Users/gauravkabra/Desktop/MCPServer/index.js"]
        }
    }
}

Replace args with absolute path (full path) of index.js on your local.

And now it should show the add tool available:

You can find documentation here.

Do CMD + I and ask to add two numbers and you should see a response which we coded in index.js.

STDIO (Standard Input-Output) is ideal on local but for remote we use SSE transport (Server Sent Event). See this to know more.
