Implementation Reference

src/minio_mcp/client.py:326-358 (handler)

The actual implementation of copy_object method in MinioClient class. Uses MinIO's copy_object API with CopySource to copy objects between buckets/locations.

def copy_object(
    self,
    source_bucket: str,
    source_object: str,
    dest_bucket: str,
    dest_object: str,
) -> dict:
    """Copy an object to another location.

    Args:
        source_bucket: Source bucket name
        source_object: Source object name
        dest_bucket: Destination bucket name
        dest_object: Destination object name

    Returns:
        Copy result
    """
    from minio.commonconfig import CopySource

    result = self._client.copy_object(
        dest_bucket,
        dest_object,
        CopySource(source_bucket, source_object),
    )

    return {
        "success": True,
        "source": f"{source_bucket}/{source_object}",
        "destination": f"{dest_bucket}/{dest_object}",
        "etag": result.etag,
        "version_id": result.version_id,
    }

src/minio_mcp/server.py:390-396 (registration)

Handler routing in call_tool function that routes minio_copy_object requests to the client.copy_object method.

elif name == "minio_copy_object":
    result = client.copy_object(
