MCPEngine: Building Production-Ready MCP Servers on AWS Lambda
2025-04-23
MCPEngine is an open-source implementation of the Model Context Protocol (MCP), enabling Large Language Models (LLMs) to call external tools. This post demonstrates building three progressively more complex MCP servers on AWS Lambda: stateless, stateful, and with Google SSO authentication. MCPEngine supports streamable HTTP alongside SSE, offering first-class support for authentication, packaging, and other capabilities for building and deploying production-grade MCP servers. The post walks through building these servers, showcasing how to run MCP tools reliably and securely in serverless environments with detailed steps and code examples.
