MCP is a standardized protocol launched by Anthropic in November 2024 and open-sourced to solve the problem of seamless integration between Large Language Models (LLMs) and external data sources and tools. Simply put, it’s like a “universal interface” that allows APIs to quickly access LLM AI applications, connecting more easily and securely to a variety of resources, and breaking down the limits of data silos.
MCP, this popular concept, is not only not difficult to understand but also very good for getting started. Its practicality is very strong. If you are starting to explore the concept of MCP, I strongly recommend you bookmark this article.
What is MCP? What Makes MCP Special?
On March 31, Google CEO Sundar Pichai threw out the phrase “To MCP or not to MCP,” which sparked a hot debate. Less than four days after Sundar Pichai solicited comments online, Philipp Schmid, Senior AI Relationships Engineer at Google DeepMind, announced on X that he had added the examples using MCP to the Gemini API documentation.
Four days later, Gemini updated its API documentation to announce its access to MCP officially. By now, AI giants such as OpenAI, Google, Anthropic, and others have all thrown themselves into the arms of the “Agent Protocol” MCP.
What is MCP?
The Model Context Protocol (MCP) is an open standard for connecting AI applications to external tools, data sources, and systems. MCP provides a common protocol for models to access contexts such as functions (tools), data sources (resources), or predefined prompts for AI models.
Models can be paired with MCP servers using the tool call feature.
The core goal of MCP is to provide a unified communication standard so that AI models or applications can easily access external data (e.g., local files, databases) and remote resources (e.g., APIs, cloud services), as well as call tools to perform tasks. It’s like the “USB-C” of the AI world: with a standardized protocol, developers don’t have to write separate interfaces for each data source or tool and can just “plug it in” and use it.
MCP adopts a client-server architecture:
- MCP Client: typically an AI application (e.g., programming tools like Claude Desktop, Cursor, etc.) that is responsible for initiating requests.
- MCP server: a lightweight program that connects to specific data sources or tools and provides services via the MCP protocol.
- Communication: based on JSON-RPC 2.0, supports local (stdio) and remote (HTTP+SSE) transfer mechanisms.
Practical Example Of MCP
- Programming Scenario: You are writing code with Cursor and want to check the table structure in a database. Previously, you had to switch to a different tool, but now, Cursor can access the database and return the results directly through the MCP server.
- Life Example: Suppose you ask the AI assistant to “check the report card in my computer, calculate the average score, and send an email to notify the students who failed the test.” MCP allows the AI to read the local file, calculate the score, and then call the email tool to send the result, which is a fully automated process.
What Makes MCP Special?
We can understand MCP with the help of the words of Kris Hansen of XNet, who says that MCP is now the equivalent of HTTP in 1993. “More products adopting this standard protocol will help everyone.”
Kris’s comparison of MCP to HTTP in 1993 makes more sense. The table below compares the two.
| Aspects | HTTP 0.9 (1993) | MCP (2025) |
| Version | 0.9, Early Release | The latest version is available in 2024 |
| Primary Functions | Transmit hypertext documents, support GET methods | Provide context for AI models, connect data sources and tools |
| Architecture | Client-server, based on TCP/IP | Client-server, standardized interfaces |
| Complexity | Very simple, no headers | Very simple; no headers |
| Adoption Stage | Early, just starting to roll out | Early, tools such as Zed and Replit started to integrate |
| Potential Impact | Becomes the foundation of the World Wide Web, leading to the Web revolution | Potentially changes the way AI data is integrated and enhances AI applications |
Both are foundational protocols in their fields, both are in early stages of development, and both have the potential to change the technology landscape.
Why is MCP So Hot?
There are several reasons for the popularity of MCP:
- Standardization: In the past, AIs wanting to use external data or tools had to develop separate docking solutions, which was time-consuming and laborious. MCP provides a common protocol, which reduces development costs.
- Flexibility: It supports everything from simple file reading to complex API calls and can adapt to a variety of scenarios, such as allowing AI to operate GitHub directly, query databases, and even generate code.
- Security: Data doesn’t have to be uploaded to the cloud, and MCP servers control resources locally, reducing privacy risks.
- Ecological momentum: Since Cursor, Claude Desktop, and other tools to support MCP, the community began to rapidly build a variety of MCP servers (such as connecting to Slack, Google Drive server), and the ecosystem is rapidly expanding.
As of today (April 8, 2025), MCP is still in a rapid development phase. In early 2025, support for tools like Cursor and Cline made it heat up, and the community is actively contributing code and server implementations. However, it is not yet fully mature; for example, the configuration interface is not user-friendly enough, and remote support is still being improved. In the future, it has the potential to become the de facto standard for how AI apps interact with the outside world, but that depends on the continued development of the ecosystem.
What are MCP Servers and Clients?
In the MCP architecture:
- MCP Servers: These lightweight programs expose external resources, tools, or data sources and act as a bridge between the AI model and the specific system. They provide functionality, such as access to local files, databases, or remote APIs, through standardized MCP protocols.
- MCP Clients: They are AI applications or agents responsible for establishing a one-to-one connection with MCP Servers to obtain data or invoke tools. Clients are typically integrated into the host application that the user interacts with, such as an IDE or AI assistant.
Choosing the “best” MCP Servers and Clients depends on your specific needs, such as development environment, type of data source, or workflow complexity. Below, I’ll list the best current options and detail their benefits and scenarios.

To MCP or Not to MCP?
“To MCP or not to MCP, that was the question.
But in 2025, when minds and models intertwine — to MCP is to thrive.”
Standardized protocols are critical to the building of the entire AI ecosystem. Just as the Internet needed the HTTP protocol to lay the foundation, the AI era also needs standards like MCP to facilitate interoperability and innovation.
Looking at the trend, the answer is clear: Yes, we should go to MCP.
But not blindly “on board”, but gradually MCP, just like the Internet from ‘browser’ to “super application”, we are moving from “AI model” to “AI system”. We are not blindly “getting on board” but gradually. MCP, just like the Internet from ‘browser’ to “super application”, is moving from an “AI model” to an “AI system”.
Why are the trends pointing to MCP?
AI is moving from “models” to “systems of capabilities.” GPT, Claude, and Gemini are no longer “single dialog tools” but intelligent modules with open interfaces.
Users are not satisfied with chatting; they want to:
- Read files → Extract data → Generate charts
- Call API → Write to database → Email notification
- Automatically take notes → Organize calendars → Report to the boss
MCP is the bridge to realize this “process automation + multi-model collaboration”. Not only that, big model vendors such as Anthropic, Open AI, Google DeepMind, and Meta have been betting on the MCP architecture; AI users are also moving from “tool people” to “AI orchestrators”, the future of high-level users, not “using an AI” but like commanders. AI users are also moving from “tool people” to “AI orchestrators”, and the future high-level users are not “using an AI” but acting like commanders, and the mission of MCP is to connect each component into an efficient system.
Our suggestion:
- If you are a developer/engineer, you should immediately lay out and use MCP Clients to connect to Claude/GPT + File Server;
- If you are a product manager or startup, you should design an MCP structure, plan AI componentized applications, and consider interfaces between models and the calling order.
- If you are an academic researcher, you are highly compatible with MCP. MCP is very suitable for intelligent body research, systematic knowledge graph experiments
- If you are an automation enthusiast, now is a good time to have a low-barrier experience. Try Claude Desktop + Filesystem Server + GitHub Server quickly!
- If you are a light AI user without many application scenarios, MCP is also difficult for you. However, you should also keep an eye on it. Just use Claude/ChatGPT Desktop for now and upgrade in the future!
