About Simple MCP Feature Sample
Simple MCP Feature Sample is a small example project for learning to build MCP servers and try them with Claude Desktop or its sample clients. It demonstrates text-processing tools and a data-server feature through single- and multi-client demos.
Key features
- 01Basic MCP server setup
- 02Text reversal and uppercase tools
- 03Data server example
- 04Single-client demo script
- 05Multi-client demo script
Use cases
- 01Learn the basics of MCP server implementation
- 02Try text-processing tools with an AI client
- 03Run demos with one or multiple clients
MCP support
Demonstrates a basic MCP server and example tools for MCP clients, including Claude Desktop and the project's sample clients.
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.
Details
From the project READMESimple MCP Feature Sample
This project includes several example implementations of MCP features.
The server script demonstrates how to set up a basic MCP server that integrates with Claude Desktop.
These server scripts also work with the simple MCP clients I developed.
How to Verify Functionality
There are two shell scripts for launching demos: one for a single client and one for multiple clients.
Launch the single client demo
Run single-client-launch-demo.sh.
$ ./single-client-launch-demo.sh
and then the console shows like below.
Connecting to the MCP server...
Command is python
Connected to the server 'simple_server'!
Waiting for server to initialize...
Server initialized!
Connected to the server with tools: ['reverse-text', 'uppercase']
MCP client started!
Type your queries or 'quit' to exit.
Query:
Please type something that you want to ask AI or quit to exit.
When you send a request containing reverse text or upper text, the AI will use the simple MCP server’s text-processing features.
Launch the multi client demo
Run multi-client-launch-demo.sh.
$ ./multi-client-launch-demo.sh
and then the console shows like below.
Connecting to the MCP server...
Command is python
Connected to the server 'simple_server'!
Waiting for server to initialize...
Server initialized!
Connected to the server with tools: ['reverse-text', 'uppercase']
Connecting to the MCP server...
Command is python
Connected to the server 'profile_data_server'!
Waiting for server to initialize...
Server initialized!
Connected to the server with tools: ['profile-data']
MultiMCP client started!
Type your queries or 'quit' to exit.
Query:
Please type something that you want to ask AI or quit to exit.
If you include Who am I? in your query, the AI will use the data MCP server feature to answer your question.
Installation for Claude Desktop
Add the following settings to your Claude Desktop configuration file:
"mcpServers": {
"simple-mcp-sample": {
"command": "python",
"args": [
"/path/to/simple-mcp-sample/server/simple_server.py"
]
}
}
"mcpServers": {
"simple-mcp-sample": {
"command": "python",
"args": [
"/path/to/simple-mcp-sample/server/data_server.py"
]
}
}
Note
If you receive a
command not founderror when launching the server, specify the full path to your Python executable.

New to MCP?
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.
