GitHub MCP Custom (Cross-Platform NPX Wrapper)

A custom-packaged version of the GitHub MCP Server that runs seamlessly on Windows, Linux, and macOS via npx. This wraps the Go binary in a Node.js launcher so developers using Claude Desktop can use GitHub MCP capabilities with no Docker or manual compilation required.

📦 Why This Exists

The official GitHub MCP Server requires:

• Docker or
• Manual Go compilation.

These options work well on Linux/macOS, but break or complicate Windows usage.

This package makes the server available via npx, eliminating the need for:

• Docker
• Go installation
• Custom PATH setups

🧠 What This Package Does

• Provides a cross-platform github-mcp-custom command
• Executes the prebuilt Go binary via Node.js wrapper
• Fully NPX-compatible on all OSes
• Works out-of-the-box with Claude Desktop or other MCP-compatible tools
• Protocol version compatible with Claude Desktop

🚀 Installation & Usage

🔹 Option 1: Run with NPX (Recommended)

npx -y github-mcp-custom@1.0.20 stdio

First-time use will download the package and run it automatically.

🔹 Option 2: Install Globally

npm install -g github-mcp-custom@1.0.20
github-mcp-custom stdio

🔹 Option 3: Direct Executable (Windows Fallback)

If NPX has issues on Windows, use the direct path:

{
  "mcpServers": {
    "github": {
      "command": "C:\\Users\\[USERNAME]\\AppData\\Roaming\\npm\\node_modules\\github-mcp-custom\\dist\\github-mcp-server.exe",
      "args": ["stdio"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "your_token_here"
      }
    }
  }
}

Replace [USERNAME] with your actual Windows username.

Note: Use @1.0.20 or later for optimal Claude Desktop compatibility.

🛠️ Prerequisites

• Node.js v14 or later must be installed
• An active GitHub Personal Access Token with proper scopes:
  • repo (for repository access)
  • read:org (for organization access)
  • user (for user information)

🔐 Creating a GitHub Personal Access Token

1. Go to GitHub Settings > Developer Settings > Personal Access Tokens
2. Click "Generate new token (classic)"
3. Select these scopes:
   • ✅ repo - Full control of private repositories
   • ✅ read:org - Read org and team membership
   • ✅ user - Update user data
4. Copy the generated token

🔧 Troubleshooting

Common Issues

❌ "Server disconnected" in Claude Desktop

• Ensure you're using version 1.0.20 or later
• Check that your GitHub token is valid and has proper scopes
• Verify the JSON configuration is valid (no trailing commas)

❌ "Command not found"

• Make sure Node.js is installed and in your PATH
• Try running npm --version to verify npm is working

❌ "Authentication failed"

• Verify your GitHub Personal Access Token is correct
• Check that the token has the required scopes (repo, read:org, user)
• Make sure the token hasn't expired

❌ "Method not found" errors

• Update to the latest version: npm install -g github-mcp-custom@latest

3. Compiled Go binaries for all platforms:

   GOOS=linux GOARCH=amd64 go build -o dist/github-mcp-server-linux ./cmd/github-mcp-server
   GOOS=darwin GOARCH=amd64 go build -o dist/github-mcp-server-macos ./cmd/github-mcp-server  
   GOOS=windows GOARCH=amd64 go build -o dist/github-mcp-server.exe ./cmd/github-mcp-server
   

4. Created a Node.js wrapper script (bin/index.js) for cross-platform execution.
5. Set up NPM-compatible package.json with proper bin configuration.
6. Published the package with protocol compatibility fixes.
