Verified Safeby awslabs
Overview
This project provides a CDK pipeline to automate the deployment of Model Context Protocol (MCP) servers as AWS Lambda functions, offering client transports for Lambda invocation and SigV4 HTTP, and server adapters/handlers for various AWS Lambda event models.

Security Notes
The project uses standard AWS SDKs for Lambda invocation and SigV4 HTTP signing, which are generally secure. The `stdioServerAdapter` runs child processes per request; while this is a common pattern for certain types of servers, it introduces a potential risk vector if the `command` or `args` parameters are sourced from untrusted input or configured insecurely. However, within the context of this deployment pipeline, these parameters are expected to be defined by the developer for trusted MCP servers. No obvious 'eval' or obfuscation is present. Hardcoded secrets are avoided by using AWS Secrets Manager for examples like the Dog Facts API Key.
