What is MCP Lambda SAM?
MCP Lambda SAM is a serverless implementation of the Model Context Protocol (MCP) built on AWS Lambda and SAM. It provides a framework for managing and invoking Lambda-based tools through a defined protocol, enabling dynamic interaction between clients and serverless functions.
How to use MCP Lambda SAM?
Administrators can deploy the application using the AWS SAM CLI or the AWS Serverless Application Repository (SAR). They can then register MCP tools, resources, and prompts using the Registration API. Clients can establish SSE connections and send commands to invoke the registered Lambda tools. IAM permissions are required for both administrators and clients to access the relevant Function URLs.
