Introduction To FAQs

Question 1

What is the MCP Inspector and how does it affect server execution?

Accepted Answer

The MCP Inspector is a development tool that proxies your server. When using `mcp dev server.py`, you are connecting to the Inspector's proxy (port 6277), not directly to your server's specified port (8050). To run your server on its defined port (8050), use `python server.py`.

Question 2

What transports does Introduction To use?

Accepted Answer

It utilizes both SSE (Server-Sent Events) and stdio transports to communicate between the client and server. This showcases different communication methods within MCP.

Question 3

How do I run the MCP server?

Accepted Answer

You can run the server using `python server.py` for normal execution. For development with hot-reloading and the MCP Inspector, use `mcp dev server.py`.  Remember to connect your client to port 6277 when using the MCP Inspector.

Question 4

What is Introduction To?

Accepted Answer

Introduction To is a minimal MCP server and client example designed to illustrate basic calculator operations using SSE and stdio transports. It's a great starting point for learning Model Context Protocol.

Question 5

How do I run the clients?

Accepted Answer

To run the stdio client, use `python client_stdio.py`. To run the SSE client, use `python client_sse.py`. Each client demonstrates a different transport method.
