SimpleCalculator using Model Context Protocol (MCP) Server & Docker

A demonstration of custom Model Context Protocol (MCP) implementation for arithmetic operations, containerized with Docker for seamless deployment.

Features

• MCP Implementation: Custom protocol handling for mathematical operations

• Core Operations: Addition, Subtraction, Multiplication, Division

• Containerized Architecture: Docker-based deployment

• Dependency Management: Modern Python packaging with pyproject.toml and uv.lock

• Protocol Security: Basic communication security through container isolation

Getting Started

Prerequisites

• Docker

Installation

git clone https://github.com/DionBenFernandes-Dev/SimpleCalculator-using-MCP-Server---Docker.git
cd SimpleCalculator-using-MCP-Server---Docker

Deployment

docker compose up --build

Protocol Implementation

The MCP server handles calculations through a custom protocol implementation. Operations are processed using the following pattern:

1. Connection: Client establishes connection to MCP server

2. Request Format:

Available tools:
  - add: Add 2 numbers
  - sub: Subtract 2 numbers
  - mul: Multiply 2 numbers
  - div: Divide 2 numbers

Enter the tool you want to use: add

Enter 1st Number: 3
Enter 2nd Number: 4

3. Response Format:

Result:: 3 + 4 = 7

Configuration

Modify environment variables in compose.yaml to adjust:

• Server port binding

• Logging verbosity

• Protocol timeouts

Development

1. Local Setup:

pip install uv # recommended

uv venv

uv add -r requirements.txt

uv run ./src/server.py

2. Testing:

uv run .\src\client.py

3. Output:

Available tools:
  - add: Add 2 numbers
  - sub: Subtract 2 numbers
  - mul: Multiply 2 numbers
  - div: Divide 2 numbers

Enter the tool you want to use: add

Enter 1st Number: 3
Enter 2nd Number: 4

Result:: 3 + 4 = 7
