Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

• copy_object

  Copy an object within S3 (same bucket or across buckets). Copies an object from one location to another. Can be used to rename objects or move them between buckets. Example response: { "success": true, "message": "Object copied from s3://source-bucket/file.txt to s3://dest-bucket/file.txt", "etag": "\"abc123\"", "lastModified": "2024-03-01T10:00:00Z" } Use cases: - Create backups of files - Move files between buckets - Rename objects (copy then delete original) - Organize files into different paths

• create_bucket

  Create a new S3 bucket. Creates an empty bucket with the specified name in the given region. Example response: { "success": true, "message": "Bucket created: my-new-bucket", "bucket": "my-new-bucket" } Bucket naming rules: - Must be globally unique across all AWS accounts - 3-63 characters long - Only lowercase letters, numbers, and hyphens - Must start and end with a letter or number - Cannot be formatted as an IP address Use cases: - Set up storage for a new project - Create buckets for different environments - Provision storage infrastructure

• delete_bucket

  Delete an S3 bucket. Permanently removes the specified bucket. The bucket must be empty before deletion. Example response: { "success": true, "message": "Bucket deleted: my-old-bucket" } Use cases: - Clean up unused buckets - Remove test/temporary buckets - Decommission old storage Note: The bucket must be completely empty (no objects, no delete markers) before it can be deleted.

• delete_object

  Delete an object from S3. Permanently removes the specified object from the bucket. Example response: { "success": true, "message": "Object deleted: s3://my-bucket/path/to/file.txt" } Use cases: - Remove outdated files - Clean up temporary data - Delete processed files - Remove incorrect uploads Note: This operation is irreversible. For versioned buckets, this creates a delete marker.

• get_object

  Get the contents of an object from S3. Returns the object content as text along with metadata. Example response: { "content": "{\"name\": \"example\", \"value\": 123}", "contentType": "application/json", "contentLength": 35, "lastModified": "2024-03-01T10:00:00Z", "etag": "\"abc123\"", "metadata": {"custom-key": "custom-value"} } Use cases: - Read configuration files - Retrieve JSON data - Download text files - Access log files Note: This tool reads objects as UTF-8 text. Binary files may not display correctly.

• head_bucket

  Check if an S3 bucket exists and is accessible. Returns whether the bucket exists and the caller has permission to access it. Example response: { "exists": true, "bucket": "my-bucket" } Use cases: - Verify bucket exists before operations - Check bucket accessibility - Validate bucket names

• list_buckets

  List all S3 buckets in the AWS account. Returns a list of bucket names and their creation dates. Example response: { "buckets": [ {"name": "my-app-data", "creationDate": "2024-01-15T10:30:00Z"}, {"name": "logs-archive", "creationDate": "2024-02-20T14:45:00Z"} ] } Use cases: - Discover available buckets in the account - Audit bucket inventory - Find bucket names for subsequent operations

• list_objects

  List objects in an S3 bucket with optional prefix filtering and pagination. Example response: { "objects": [ {"key": "data/file1.json", "size": 1234, "lastModified": "2024-03-01T10:00:00Z"}, {"key": "data/file2.json", "size": 5678, "lastModified": "2024-03-02T11:00:00Z"} ], "commonPrefixes": ["data/subdir/"], "isTruncated": false } Use cases: - Browse bucket contents - Find files matching a prefix pattern - List "folders" using delimiter - Paginate through large buckets

• put_object

  Upload or update an object in S3. Creates a new object or overwrites an existing one with the provided content. Example response: { "etag": "\"abc123def456\"", "versionId": "v1.0" } Use cases: - Store configuration files - Upload JSON data - Create text files - Save generated content Note: This tool handles text content. For binary files, use base64 encoding or a different approach.
