The AWS S3 MCP Server provides a standardized and secure way to interact with Amazon S3 buckets and objects through the Model Context Protocol (MCP). It enables AI agents and other MCP clients, such as Claude Desktop or VS Code, to list buckets, browse objects, and generate presigned URLs for both downloading and optionally uploading files. Designed with security in mind, it's safe by default with write operations explicitly requiring enablement, and features robust input validation and structured logging for reliable integration.
