MCP Starter KitClass-based MCP server starter

Build tools, resources, and prompts in TypeScript with decorators, Zod schemas, and dependency injection.

Class-based capabilities
One decorated class per tool, resource, or prompt. Metadata lives on the class, handlers stay plain TypeScript.
Scaffold generator
Generate a working tool, resource, prompt, or service with schemas, types, and tests. Preview with dry-run, never overwrite.
Type-safe contracts
Zod schemas validate every input and argument. TypeScript types derive from those schemas, so contracts and code stay in sync.
Dependency injection
Share business logic through injectable services with singleton, transient, and per-call factory lifetimes.
Inspectable registry
One explicit registration list owns what your server exposes. List it from the terminal without starting the server.
Stdio-first runtime
Build once, run over stdio, connect Cursor or the MCP Inspector. Logs go to stderr so stdout stays clean for protocol traffic.

Build your server in four steps

npx @im4all/create-mcp-starter-kit my-server
cd my-server
npm install
npm run build

Then generate your first capability, register it, and run the server.

npm run generate tool multiply --dry-run
npm run generate tool multiply
npm run list:capabilities
npm start
