I attempted to run an MCP server serverlessly on AWS Lambda using FastAPI, FastMCP, and the Lambda Web Adapter. While it technically worked, the developer experience was rough—cold starts were slow, observability was limited, and testing was clunky. Compared to my experience building with Bedrock agents, this felt like a step backward. MCP is promising, but today, running it on Lambda isn’t production-ready. Here’s my full breakdown and thoughts.

In this post, you'll learn how to use AWS Lambda functions as both data sources and event handlers for publish and subscribe actions in AWS AppSync Events. We’ll walk through setting up a namespace, wiring direct Lambda integrations using CDK, and handling real-time events with Powertools for AWS Lambda. This approach gives you full control, observability, and flexibility—all while keeping your WebSocket architecture serverless and scalable.

This post walks through building a stateless Model Context Protocol (MCP) server on AWS Lambda using Streamable HTTP—no custom bridges or transports. It explores MCP internals, tool/resource definitions, deployment with API Gateway, and local testing with stdio. Learn how Agentic AI Assistants leverage MCP to execute actions with real-time context, and how this protocol simplifies integration across diverse systems.
