Why MCP Production Kit?

Most open-source MCP examples are proof-of-concepts: they demonstrate a toy tool over local stdio, but fail when faced with real-world deployments.

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 protocol framing. Diagnostics are piped to stderr with automated secret redacting to prevent pipe corruption.

• Hardened Security & SSRF Defense: The built-in HTTP fetch tool blocks loopback addresses, 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 endpoint.

Quickstart

1. Installation

git clone https://github.com/A7mdMe/mcp-production-kit.git
cd mcp-production-kit
npm install
npm run build

2. Run Verification Tests

npm test

3. Connect to Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "production-kit": {
      "command": "node",
      "args": [
        "/path/to/mcp-production-kit/dist/index.js",
        "--transport=stdio"
      ]
    }
  }
}

4. Run as Remote HTTP/SSE Server

npm run start:sse
# Listening on http://localhost:3000
# Healthcheck: http://localhost:3000/health
# SSE Stream: http://localhost:3000/sse

5. Run via Docker

docker build -t mcp-production-kit .
docker run -p 3000:3000 -e TRANSPORT=sse mcp-production-kit
