Python Server MCP - Cryptocurrency Price Service

This project implements an MCP (Model Context Protocol) server that provides cryptocurrency price information. The server is built using Python and the MCP framework to create an API that can be consumed by different clients.

Features

Real-time cryptocurrency price retrieval
Environment-based configuration (development, production, staging, local)
CoinMarketCap API integration
Docker container deployment

Requirements

Python 3.12+
uv (package and virtual environment manager)
Docker (optional, for container execution)

Installation

Using uv (recommended)

# Clone the repository
git clone <repository-url>
cd PythonServerMcp

Create and activate virtual environment with uv

uv venv
source .venv/bin/activate

Install dependencies

uv sync

Configuration

Create a .env file in the project root with the following variables:

ENVIRONMENT=DEV  # Options: LOCAL, DEV, STAGING, PROD
COINMARKETCAP_API_KEY=your_api_key_here

You can also create specific environment files for each environment:
- .dev.env - For development environment
- .staging.env - For staging environment
- .prod.env - For production environment

Usage

Local Execution

python main.py

This will start the MCP server that will listen for requests through standard input/output (stdio).

Using Docker

# Build the image
docker build -t test-mcp -f Dockerfile --platform linux/amd64 .

# Run the container
docker run -it test-mcp

Development

Adding New Tools to the MCP Server

To add a new tool to the MCP server, follow these steps:

Define the function in the src/__init__.py file
Register the tool in the main() function
Document the tool with docstrings

Example:

@server.add_tool
def my_new_tool(parameter1: str, parameter2: int) -> str:
    """
    Description of what the tool does.
    
    Args:
        parameter1: Description of parameter 1
        parameter2: Description of parameter 2
        
    Returns:
        Description of what is returned
    """
    # Tool implementation
    return result
