What is MCP?
Model Context Protocol
MCP (Model Context Protocol) is an open protocol that enables artificial intelligence applications to connect to external data and tools in a standard way.
Definition and Word Origin
Instead of writing separate connections for each application, a single standard is used. The protocol is an open standard developed to increase the interoperability of the AI ecosystem. The socket analogy is apt: Just as every device works with the same plug, different data sources connect to AI in the same way.
How to Know and Use in Daily Life?
Assistants: The artificial intelligence application reads your calendar and files.
Development: Linking the code editor to the repository and documentation.
Reporting: Summary extraction from live database.
Technical Depth and Architecture
The architecture consists of three parts:
Shoo: AI application (e.g. desktop assistant or editor).
Client: Connection manager within the host.
Server: Small program that presents data or tool (file system, database, GitHub).
Servers offer three capabilities:
Tool: Function that the model can call (file search, query execution).
Resource: Data (document, schema) that the model can read.
Prompt: Ready task template.
A typical client setting is as follows:
{
"mcpServers": {
"dosya": {
"command": "npx",
"args": ["-y", "ornek-mcp-dosya"]
}
}
}Security rule: The server only accesses allowed folders and processes. Every request of the model must be able to pass user approval.
Frequently Mixed Things
Can be mixed with API. API is a single gate, while MCP is the rule set that ensures that the data passing through this gate is spoken in a standard language. API is server specific, MCP is common across servers.
Use in Different Disciplines
Electric: The socket standard that every device complies with.
Railway: Hook standard for connecting wagons.
Language: Common protocol language used in diplomacy.
Questions and answers
Why is MCP necessary?
Instead of writing a separate link for each application, the standard method is followed. This simplifies safety and maintenance.
Is MCP open source?
Yes. It is an open standard, different applications can write their own clients and servers.
Why use MCP instead of API?
API is specific to the server, each is learned separately. MCP offers a common language, the model connects to the new server ready.
Is it safe?
Its design is permission-based, but you need to keep the server's access scope narrow and require approval for writes.
