About MCP Server Demo
A Python demo project showing basic MCP server operation over stdio and SSE. It is suited to local testing and exploring basic server-client interaction.
Key features
- 01Demonstrates stdio and SSE transports
- 02Local testing with MCP Inspector
- 03Direct Python server execution
- 04Example SSE client
Use cases
- 01Testing a server with MCP Inspector
- 02Running a Python MCP server
- 03Trying an SSE client connection
MCP support
Demonstrates running an MCP server over stdio and SSE, and provides a way to test its tools and resources through MCP Inspector.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

Running the Server
There are several ways to run MCP server:
1. Development Mode with MCP Inspector
The easiest way to test server is using the MCP Inspector:
mcp dev server.py
This runs server locally and connects it to the MCP Inspector, a web-based tool that lets you interact with server's tools and resources directly. This is great for testing.
2. Direct Execution (only needed or SSE)
Run the server directly:
# Method 1: Running as a Python script
python server.py
# Method 2: Using UV (recommended)
uv run server.py
Finally run clients:
# Running as a Python script
python client-sse.py

From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
