MCP Server Scaffolding

Use this skill when you need to create a new MCP server from scratch. Generates a production-ready project with TypeScript, Vitest tests, GitHub Actions CI, and error handling patterns.

Usage

npx create-mcp-server-pro my-server

Non-Interactive (Agent-Friendly)

npx create-mcp-server-pro my-server \
  --name mcp-server-weather \
  --description "Weather forecasts for AI assistants" \
  --auth \
  --author "Your Name"

What Gets Generated

• TypeScript with strict mode and MCP SDK v2
• Vitest test setup with a sample tool test
• GitHub Actions CI pipeline
• Error handling patterns (MCP-compliant error responses)
• Agent-friendly README with tool table, quick start, and examples
• ESLint 9 + Prettier config
• Optional auth boilerplate (API token validation)

Key Patterns

• Pass --auth for servers that need an API token; --no-auth for zero-config servers
• The generated src/index.ts has a working example tool — replace it with your real tools
• Tests use @modelcontextprotocol/sdk/test utilities for MCP protocol-level testing
• The official MCP scaffolder was archived — this is the maintained replacement
