What is MCP according to Anthropic? (Model Context Protocol)

Author: Adarsh ​​Menon

Originally published in the direction of artificial intelligence.

during learning Fr. MCPInitially, I was embarrassed in relation to its functionality; My confusion deepened during architecture.

When I say “architecture is quite complicated”, I mean:-

Anthropic motivation: “The models are as good as the context provided to them”

So this blog tries to simplify complex structures for everyone interested in getting to know them. McP has recently developed in X, so I wanted to study it. On this blog we will find out about it and how to implement it.

This blog will explain:
a.) What is MCP?
b.) How does MCP work and its necessity?
c.) MCP architecture?
d.) Basic MCP implementation?
e.) What are the advantages and disadvantages of MCP?
f.) What are potential future changes and evolution?

a.) What is MCP?

The Context Protocol is an open standard that allows programmers to build safe, two -way connections between their data sources and AI powered tools. Architecture is simple: programmers can either reveal their data via MCP servers or build AI applications (MCP clients) that connect to these servers. (Definition according to anthropics)

Anthropic defines MCP as Connecting customers with a medium server that connects other API interfaces and reveals tools, resources and hints. Revealing funds Displaying existing functions or surnames to users. The Context Protocol is currently Open Sourcewhich means that everyone can build own MCP server or use one of Existing MCP servers We will discuss. The contextual protocol of the model enables applications offer a context for LLM in a consistent wayisolation concerns about the provision of context from the actual interaction of LLM.

MCP is an open protocol of standardization of the way applications provide the context to LLM. Think MCP as a USB-C port Down AI applications. MCP provides Standardized ways of connecting AI models with many data sources and toolsLike USB-C for connecting devices to ports and accessories.

. Context Protocol (MCP) allows you to build servers that reveal data and functionality for LLM applications in a normalized manner. Think about how about the interface of the Internet, but specially designed for LLM interaction. MCP servers can:

• Disclose Data via resources (Think about this kind of obtaining end points; they are used to charge information to the LLM context)
• Provide Functionality through tools (something like end points; they are used to perform code or otherwise producing a side effect)
• Define Interaction patterns through hints (Multiple use templates for LLM interaction)

b.) How does MCP work and its necessity?

McP can serve as a basic framework for agencies. Consider an AI agent, whose task is to send messages via Slack or access to the database; Configuring the API interface can be burdensome. However MCP serverIN You can access many applications In Standardized way.

This is a simple explanation of how MCP works, offering Unified APITurning on LLM Selecting tools and execution of instructions. It resembles Electricity functioning as a client/host, with a server supporting a server that contains the necessary tools, resources (potentially user manual)and so on. This is mine Interpretation or perspective of the functioning of MCP.

c.) MCP architecture?

At the baseIN MCP follows the architecture of a server customer in which the Host application can connect to many servers.

These are parts of architecture:-

MCP hosts: Applications such as Claude DesktopANDNtegrated programming environments (IDES) or artificial intelligence tools seeking access to data via MCP.

MCP clients: Protocol customers who maintain One to one to one with servers.

MCP servers: Efficient applications that each Provide separate functions By Standardized contextual protocol of the model .

Regional data repositories: FILS, databases and services on your computer that MCP servers can safely access.

Remote services: External services Available online (e.g. via API interfaces), to which MCP servers can connect.

Basic concepts:

1. ) Server: The fastmcp server is yours Basic interface down MCP protocol. Supports Connection management, compliance of the protocol and routing messages.

2.) Resources: Resources are the way you expose data to LLM. They are similar to obtain end points in the API REST interface – they provide data, but should not perform significant calculations or side effects.

3.) Tools: Let LLM tools Activities through your server. Unlike resources, The tools are expected to perform calculations and have side effects.

4.) The hints are Reusable templates that help in LLM interaction with the server effectively.

5.) context: Contextual object provides its tools and resources, access to MCP functions.

The Context Protocol (MCP) model is constructed on a versatile, expanding frame that facilitates uninterrupted communication in applications and LLM integration. This document applies to basic architectural elements and principles.

MCP observes customer-server architecture, in which:
Blue hosts These are LLM software (such as Claude Desktop or integrated programming environments) that create connections.
Clients Maintain one to one to one with servers in the Host application.
Servers Providing the background, tools and hints to customers.

d.) Basic MCP implementation?

We have developed the basic version of the MCP, including a tool that provides or returns Your nameindicating its addition. This serves as a demonstration, basically “Hello World” MCP. Use of MCP, one can save and download memory, call API interfaces and perform more functions. We provided our URL Github address for the project; You can review it. To conduct tests, we use the tool called MCP inspectorWhich checks that tools, resources or hints are exposed AND done. It is primarily expected to test it with Claude Desktop or Cursor IDEAlthough you can also Use the inspector mode.

e.) What are the advantages and disadvantages of MCP?

-> Advantages:-

• Strengthens Contextual understanding in large language models by Structural context management.
• Reduces the context window Restrictions through effective organization of information.
• Better facilitates Information search from the history of conversation.

-> Disadvantages:-

• Is currently compatible with Cursor IDE, Windsurf IDE AND CLAUDE Desktop How clients.
• The use of MCP servers from external organizations may cause problems related to Safety and safety of work flow or software.
• Still relatively newWith The evolving best practices and standards.
• Power require specialist knowledge Down effectively.

f.) What are potential future changes and evolution?

I think it is relatively new, published by Anthropic in November, doing it 3.5 months When I write it. It may be a changing game in the future because it is equipped Intelligent systems with unusual tools that improve the overall workflow and facilitate full autonomy. This protocol can contribute to this purpose, so we must remain patient for about 4-5 months to observe its development. A very developed version will probably be released, resulting from the existing MCP. This is technology It also affects the current AI landscape.
