S3
Connects Claude to AWS S3 using the standard credential chain from your environment or ~/.aws/credentials. Exposes seven tools: list_buckets, list_objects, get_object, put_object, delete_object, presigned_url, and bucket_info. You can ask Claude to browse bucket contents with prefix filters, download config files as text, upload content directly, or generate temporary sharing links with custom expiration. Requires standard S3 permissions like s3:ListBuckets and s3:GetObject. Reach for this when you're already managing S3 from the CLI and want to hand off bucket operations to your assistant instead of remembering aws s3 syntax and flags.
