What is quickstart-python MCP?
quickstart-python provides a minimal template for building Model Context Protocol servers using the official Python SDK and stdio transport.
Summary generated from the project's README
About quickstart-python MCP server
Building custom Model Context Protocol servers using Python becomes straightforward with this minimal template. It provides a foundational structure for developers who want to implement the official Python SDK and utilize stdio transport for communication. The template includes a single typed tool to demonstrate how functionality is exposed to an AI client.
Setting up the environment requires Python 3.10 or higher and the installation of dependencies via pip. Users can verify the implementation by running a client script that initiates the MCP handshake, lists available tools, and executes the hello_world command. Because the server communicates through stdout, developers must direct all diagnostic messages to stderr to avoid interfering with protocol traffic.
This project serves as a starting point rather than a production-ready service. It does not include built-in authentication, network services, or persistent state management. For those maintaining code quality, the repository includes requirements for linting, type checking, and testing.
What you can do with it
- 1Initialize a new MCP serverA developer can use this template to quickly scaffold a new server implementation using the official Python SDK.
- 2Test tool execution via stdioYou can verify that your tool definitions and handshake logic work correctly by running the provided client script.
- 3Verify code quality and typesDevelopers can run linting and type checks to ensure their server implementation follows standard Python practices.

View on GitHubMCP Quickstart (Python)
A minimal Model Context Protocol server built with the official Python SDK. It uses the standard stdio transport and exposes one typed tool.
Setup
- Ensure Python 3.10+ is installed.
- Install dependencies:
python -m pip install -r requirements.txt. - Run
python client.py; it starts the server over stdio, performs the MCP handshake, lists the tool and callshello_world.
The server writes protocol traffic to stdout through the SDK. Do not print
diagnostics there; use stderr for diagnostics. This example has no network
service, authentication or persistent state. Run python -m pip install -r requirements-dev.txt for lint, type and test checks.
quickstart-python MCP questions
What version of Python is required?
You must have Python 3.10 or higher installed to use this template.
Does this server require authentication or a network service?
No, this example does not include a network service, authentication, or any persistent state.
How should I handle diagnostic messages?
You should use stderr for diagnostics instead of stdout to avoid interfering with protocol traffic.
