27 Nov Traditional API Approach vs MCP
To understand the traditional API and MCP, here, we will see a diagram. The diagram captures a key conceptual shift from traditional API.
It captures the general idea behind the MCP server’s role compared to the traditional approach, and illustrates the standardization and abstraction MCP aims to deliver.

It captures the general idea behind the MCP (Model Communication Protocol) server’s role compared to the traditional approach, and illustrates the standardization and abstraction MCP aims to deliver.
Traditional API Model
- Each model (Cursor, ChatGPT, Claude AI, etc.) is accessed individually, often requiring custom API integrations for each use case.
- Developers must write unique code and handle diverse request/response formats for every model.
- Scalability and maintainability are limited due to this fragmentation.
MCP Server Approach
- All models (Cursor, ChatGPT, Claude AI, etc.) become accessible through a standardized MCP protocol.
- The MCP Server acts as an abstraction layer, allowing developers to send requests using a unified interface, regardless of the underlying model or vendor.
- This reduces integration work, enables interoperability, and simplifies switching or combining models within the same application.
Diagram Summary
The diagram correctly shows:
- In the traditional approach, every interaction requires direct and potentially unique API communication, resulting in multiple separate integrations.
- With the MCP approach, all models interface through a standardized MCP layer, and MCP Servers handle the details, leading to improved interoperability and system coherence.
This conceptualization is accurate and reflects how MCP servers facilitate smoother multi-model or multi-vendor AI orchestration.
