Production‑Grade MCP Server Blueprint (200+ Line index.ts + Full System)

This blueprint delivers a complete, production‑grade MCP server that can be deployed without the usual trial‑and‑error. All routing, error isolation, metrics, authentication guards, and logging are already implemented, so you can focus on business logic instead of plumbing. The codebase is over 200 lines of real implementation with explanatory comments that describe why each piece exists, removing guesswork and reducing onboarding time.

What You Get

• mcp-server/index.ts – entry point that wires together router, middleware, and server start‑up.
• mcp-server/router.ts – request routing with type‑safe definitions.
• mcp-server/tool-registry.ts – central registry for reusable tools and services.
• mcp-server/errors.ts – structured error classes and a global error handler.
• mcp-server/metrics.ts – Prometheus‑compatible metrics collection.
• mcp-server/validators.ts – input validation utilities.
• mcp-server/auth-guards.ts – authentication and authorization guards.
• mcp-server/logger.ts – configurable logger with request tracing.
• SETUP-GUIDE.md – step‑by‑step instructions for installing dependencies, configuring environment variables, and starting the server.
• TROUBLESHOOTING.md – list of more than ten common issues and their resolutions.

How to Use

Clone the repository, run npm install (or yarn) to pull dependencies, then copy the .env.example to .env and fill in your configuration values. Execute npm run build to compile TypeScript, and start the server with npm start. The server will expose health endpoints, metrics at /metrics, and any routes you add to router.ts. To add new functionality, create additional modules that register with tool-registry.ts and reference them in the router. All error handling, logging, and metric collection work automatically because they are wired into the core bootstrap code.

Who This Is For

Developers who need a ready‑to‑deploy MCP server – you can integrate it into an existing project or use it as a starting point for a new service without spending hours on boilerplate.

Teams that require built‑in security and observability – authentication guards, structured errors, and metrics are already present, satisfying typical compliance checklists.

Solo engineers who cannot afford extensive debugging – the code is complete, commented, and free of placeholder TODOs, so you can move from clone to production in a single workday.
