create-mcpserver

Scaffold a new MCP (Model Context Protocol) server in seconds.

The official @modelcontextprotocol/create-server is deprecated. This is its modern replacement — fast, interactive, and built for the MCP SDK v1.27+.

npx create-mcpserver

Features

• Interactive CLI — Beautiful prompts powered by @clack/prompts
• 4 Templates — Basic, Tools, Resources, Full (kitchen sink)
• Transport Choice — stdio (Claude Desktop & Claude Code) or Streamable HTTP
• Testing Setup — Optional Vitest configuration out of the box
• Modern API — Uses registerTool / registerResource / registerPrompt (not deprecated server.tool())
• MCP SDK v1.27+ — Latest SDK with McpServer class, Zod validation, and more
• Fast — Embedded templates, no git clone. Scaffolds in <1 second
• Package Manager Detection — Works with npm, pnpm, yarn, and bun

Quick Start

# Interactive mode
npx create-mcpserver

# With project name
npx create-mcpserver my-weather-server

# Accept all defaults
npx create-mcpserver my-server --yes

  ✔ Created my-weather-server/
  ✔ Dependencies installed

  Next steps:
    cd my-weather-server
    npm run dev          # Start with hot reload
    npm run build        # Build for production
    npm run inspect      # Test with MCP Inspector

Templates

Basic

Minimal MCP server with a single example tool. Perfect for getting started.

Tools (Recommended)

Multiple tools with Zod input validation:

• hello — Greet a user
• calculate — Math operations (add, subtract, multiply, divide)
• get-timestamp — Current time in ISO, Unix, or human-readable format
• generate-uuid — Generate a random UUID v4

Resources

Static and dynamic resource examples:

• info://server — Server information (static)
• greeting://{name} — Dynamic greeting by name
• config://default — Default configuration (static)
• env://{key} — Environment variable lookup (dynamic)

Full (Kitchen Sink)

Everything — tools, resources, and prompts:

• All tools from the Tools template
• All resources from the Resources template
• summarize — Prompt to summarize text
• code-review — Prompt to review code
• explain — Prompt to explain a topic at different levels

Transport Options

stdio (Default)

Works with Claude Desktop and Claude Code. The server communicates over standard input/output.

{
  "mcpServers": {
    "my-server": {
      "command": "node",
      "args": ["path/to/my-server/dist/index.js"]
    }
  }
}

Streamable HTTP

For web deployment. The server runs as an Express HTTP server.

PORT=3000 npm start

{
  "mcpServers": {
    "my-server": {
      "url": "http://localhost:3000/mcp"
    }
  }
}

CLI Options

Development

After scaffolding, your project includes:

npm run dev          # Start with hot reload (tsx watch)
npm run build        # Build TypeScript to dist/
npm run inspect      # Open MCP Inspector for testing
npm start            # Run the built server
npm test             # Run tests (if testing enabled)

Why This Exists

The MCP ecosystem has exploded — the reference repo has 79k+ stars and there are 17,000+ MCP servers. But the official scaffolding tool (@modelcontextprotocol/create-server) was deprecated at v0.3.1.

create-mcpserver fills that gap with:

• Modern interactive UX (not just boring prompts)
• Up-to-date MCP SDK support (v1.27+ with latest registerTool API)
• Transport choice (stdio + HTTP)
• Testing setup out of the box
• Sub-second scaffolding (embedded templates, no git clone)
