The enterprise-ready, type-safe TypeScript starter kit for building Model Context Protocol (MCP) servers.
Designed for Claude Desktop, Cursor, Antigravity, and autonomous AI agent architectures.
Most open-source MCP examples are toys: they demonstrate a simple add(a, b) function over local stdio, but fail when deployed to production.
MCP Production Kit solves the core engineering hurdles out of the box:
Dual Transport Architecture: Run locally on stdio (for Claude Desktop / Cursor) OR remotely over HTTP / Server-Sent Events (SSE) using a single codebase.
Zero-Leak Logging: In stdio mode, stdout is strictly reserved for JSON-RPC message framing. Our structured logger routes all diagnostics to stderr with automated secret redacting to prevent pipe corruption.
Hardened Security & SSRF Defense: The built-in HTTP fetch tool blocks loopback, private IPv4/IPv6 ranges, and cloud metadata endpoints (169.254.169.254).
In-Memory Agent Persistence: Includes an isolated, namespaced key-value state store with configurable TTL for multi-step agent reasoning.
Production Observability: Built-in OS telemetry, memory metrics, and /health monitoring.
