MinIO Tool

Node catalog Artificial intelligence

On this page

Let an AI agent call MinIO object storage operations

Usage and specifics

Folders are object prefixes, not ordinary directories. Set bucket and key for the operation. delete_folder removes objects under the prefix; a presigned URL grants temporary access.

Technical type : ai_tool_minio. Runtime : nodulz.

Credentials and prerequisites

Create and configure the credential : minio

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the credentials guide for access and rotation.

Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
