Node.js MCP Server Boilerplate for Claude & Cursor (Docker + API Integrations)

Stop wrestling with broken MCP servers. Start shipping production-ready integrations in under 10 minutes.

You try to build an MCP server for Claude or Cursor and everything falls apart. The schema won’t validate. The tools won’t register. The IDE throws a vague “connection failed” error you can’t debug. You lose hours chasing problems that shouldn’t exist in the first place.

This boilerplate gives you a fully working Node.js MCP server with strict schemas, secure tool execution, and preconfigured Claude and Cursor integration files. It includes a production-grade Docker setup, a validated routing layer, and ready-to-use tools so you can focus on your actual product instead of fighting infrastructure.

What's Included:
- Complete Node.js MCP server with schema-enforced routing and strict request/response validation
- Preconfigured Claude and Cursor client integration files for instant IDE connection
- Production Dockerfile, docker-compose, and healthcheck scripts
- Secure SQL tool with parameterized query support and sandboxed connection handling
- FS sandbox tool with path‑whitelisting to prevent directory escapes
- HTTP wrapper tool with required safety guards and response parsing
- 6 environment templates for local, staging, and production setups
- Error‑safe logging and audit middleware
- Example tool tests so you can extend safely without regressions

Built from patterns used to deploy MCP servers that run in production environments handling real user data and strict security requirements. Every file comes from solving the exact integration failures developers hit when trying to make Claude or Cursor recognize and trust their tools.

Who This Is For:
- Developers who want Claude or Cursor tools working today, not after a weekend of debugging
- Teams adding AI‑driven automation to existing Node.js apps and need a safe MCP foundation
- Solo builders who don’t have time to figure out Docker, schemas, and integration quirks from scratch

Who This Is NOT For:
- Developers who want to hand‑roll every file from zero
- Anyone building in Python, Go, or Rust instead of Node.js

If this doesn’t save you at least 6 hours of setup and debugging, reach out for a full refund.
