Math Operations MCP Server

A simple Model Context Protocol (MCP) server with HTTP SSE (Server-Sent Events) transport that performs basic math operations on two numbers.

Features

• 6 Math Operations: add, subtract, multiply, divide, power, modulo
• HTTP SSE Transport: Connect from anywhere via HTTP streaming
• Easy Deployment: Deploy to Railway, Render, Heroku, or any platform
• Claude Integration: Connect directly to Claude for AI-powered calculations

Available Operations

1. add - Add two numbers together
2. subtract - Subtract the second number from the first
3. multiply - Multiply two numbers together
4. divide - Divide the first number by the second
5. power - Raise the first number to the power of the second
6. modulo - Calculate the remainder when dividing

Quick Start

Local Development

1. Install dependencies:

pip install -r requirements.txt

2. Run the server:

python server.py

The server will start on http://localhost:3000

3. Test the server:

# Health check
curl http://localhost:3000/

# SSE endpoint (for MCP connection)
curl http://localhost:3000/sse

Deployment Options

Option 1: Railway (Recommended)

1. Install Railway CLI:

npm i -g @railway/cli

2. Login and deploy:

railway login
railway init
railway up

3. Get your deployment URL from Railway dashboard

Option 2: Render

1. Create account at render.com
2. Click "New +" → "Web Service"
3. Connect your GitHub repository
4. Render will auto-detect the render.yaml configuration
5. Click "Create Web Service"
6. Copy your deployment URL (e.g., https://your-app.onrender.com)

Option 3: Heroku

1. Install Heroku CLI and login:

heroku login

2. Create and deploy:

heroku create your-app-name
git push heroku main

3. Get your URL:

heroku open

Option 4: Docker

1. Build the image:

docker build -t math-mcp-server .

2. Run the container:

docker run -p 3000:3000 math-mcp-server

Connecting to Claude

Once deployed, you can connect this MCP server to Claude Desktop or Claude Code.

Claude Desktop Configuration

Edit your Claude Desktop config file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json

Add your server:

{
  "mcpServers": {
    "math-operations": {
      "url": "https://your-deployed-url.com/sse"
    }
  }
}

Replace https://your-deployed-url.com with your actual deployment URL.

Claude Code Configuration

Add to your mcp_config.json:

{
  "mcpServers": {
    "math-operations": {
      "url": "https://your-deployed-url.com/sse"
    }
  }
}

Testing the Connection

After connecting to Claude, try asking:

• "What's 25 + 17?"
• "Calculate 144 divided by 12"
• "What's 2 to the power of 10?"
• "What's 100 modulo 7?"

Claude will use your deployed MCP server to perform these calculations!

API Endpoints

• GET / - Health check and server info
• GET /sse - SSE endpoint for MCP connections
• POST /messages - Message handling endpoint

Environment Variables

• PORT - Server port (default: 3000)

Development

The server is built with:

• mcp - Model Context Protocol SDK
• starlette - Lightweight ASGI framework
• uvicorn - ASGI server

Troubleshooting

Connection Issues

1. Check server is running: Visit https://your-url.com/ to see the health check
2. Verify SSE endpoint: The SSE endpoint should be at /sse
3. Check logs: View deployment logs in your platform dashboard
4. CORS issues: The server accepts all origins for SSE connections

Claude Can't Connect

1. Verify the URL in your config is correct
2. Make sure it ends with /sse
3. Restart Claude Desktop/Code after config changes
4. Check that your deployment is publicly accessible
