aws-mcp-server and mcp-server-s3
These are complements: the AWS CLI server provides general command execution capability that can invoke S3 operations, while the S3-specific server offers optimized, direct S3 bucket management through MCP—users would choose based on whether they need broader AWS access or dedicated S3 functionality.
About aws-mcp-server
alexei-led/aws-mcp-server
A lightweight service that enables AI assistants to execute AWS CLI commands (in safe containerized environment) through the Model Context Protocol (MCP). Bridges Claude, Cursor, and other MCP-aware AI tools with AWS CLI for enhanced cloud infrastructure management.
Exposes AWS CLI through two dynamically-documented tools (`aws_cli_help` and `aws_cli_pipeline`) that let Claude discover and execute commands on-demand rather than wrapping individual APIs. Implements multiple transport protocols (stdio, streamable-http) with configurable sandboxing modes and strict output/timeout limits, relying on IAM policies as the primary security boundary. Supports Docker containerization for host isolation and credential passing via environment variables or AWS config files, with graceful shutdown and proper MCP error handling.
