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

• s3_create_bucket

  Create a new S3 bucket. Bucket names must be globally unique (on real AWS) and follow S3 naming rules (lowercase, 3-63 chars, no underscores).

• s3_delete_bucketcan change or delete data

  Delete an S3 bucket. The bucket must be empty first (delete all objects with s3_delete_object, or s3_list_objects + loop). Irreversible.

• s3_delete_objectcan change or delete data

  Delete a single object from an S3 bucket. Irreversible unless the bucket has versioning enabled.

• s3_get_objectread-only

  Read an S3 object's content. Returns text directly if the object is valid UTF-8 text; otherwise (or if base64=true) returns base64-encoded content. Output is capped by max_bytes (default 200,000, hard cap 5,000,000) to avoid dumping huge objects — use s3_head_object first to check size.

• s3_head_objectread-only

  Get metadata for one S3 object (size, content type, last modified, ETag) without downloading its body.

• s3_list_bucketsread-only

  List S3 buckets visible to the configured credentials. Call this first to confirm AWS credentials and endpoint (real AWS or LocalStack) are working.

• s3_list_objectsread-only

  List objects in an S3 bucket, optionally filtered by key prefix. Paginated via continuation_token.

• s3_put_object

  Write an object to S3. Intended for small text/config/data objects (limit 5,000,000 bytes per call), not bulk file upload. Set base64=true to write binary content passed as base64 text.
