🚀 Claude Desktop Setup (5 Minutes)

Step 1: Install mcp-connect

npm install -g @myatkyawthu/mcp-connect

Step 2: Create mcp.config.js

Step 2: Create Your MCP Server

# Navigate to your project directory
cd your-project

# Generate sample config
mcp-connect init

This creates mcp.config.js with example tools:

import { defineMCP } from "@myatkyawthu/mcp-connect";

export default defineMCP({
  name: "My MCP App",
  version: "1.0.0",
  tools: [
    ["hello", async ({ name = "World" }) => `Hello ${name}!`],
    ["echo", async ({ message }) => `Echo: ${message}`]
  ]
});

Step 3: Test Locally

Step 3: Configure Claude Desktop

Open Claude Desktop config file:

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

Add your MCP server:

{
  "mcpServers": {
    "my-app": {
      "command": "mcp-connect",
      "args": ["C:/full/path/to/your/mcp.config.js"]
    }
  }
}

Important: Use the full absolute path to your mcp.config.js file.

Step 4: Start & Test

1. Restart Claude Desktop completely
2. Test connection: Ask Claude "What tools do you have available?"
3. Use your tools: Try "Hello there!" or "Echo this message"

✅ Done! Your functions are now available to Claude Desktop.
