MinIO AIStor MCP Server
Official MinIO MCP server for AIStor — MinIO's AI-optimized object storage platform. Enables AI agents to interact with MinIO's S3-compatible object storage with AI-specific features: managing buckets and objects, accessing vector embeddings storage, integrating with AI/ML pipelines, and leveraging MinIO's high-performance object store for AI workloads including model storage and dataset management.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Self-hosted object storage. TLS + access key auth. IAM policy scoping available. Official MinIO MCP. Encryption at rest configurable. AGPL license for commercial deployments.
⚡ Reliability
Best When
A team running MinIO for AI/ML infrastructure wants agents to manage AI artifacts, datasets, and embeddings — official MCP from MinIO engineering with AIStor-specific feature support.
Avoid When
You use standard AWS S3 without MinIO — use AWS S3 MCP instead. MinIO AIStor is for self-hosted or MinIO-specific deployments.
Use Cases
- • Managing AI model artifacts and datasets in MinIO from MLOps agents
- • Storing and retrieving embeddings and vector data from RAG pipeline agents
- • Accessing S3-compatible object storage from data ingestion agents
- • Managing AI training data buckets and versioning from machine learning agents
- • Integrating object storage into AI inference pipelines from serving agents
Not For
- • Standard S3-only workflows without AI storage requirements (use AWS S3 MCP for basic S3)
- • Teams without MinIO deployed (requires MinIO cluster or AIStor subscription)
- • Traditional relational database storage (MinIO is object storage, not SQL)
Interface
Authentication
MinIO access key and secret key required. Set MINIO_ENDPOINT, MINIO_ACCESS_KEY, MINIO_SECRET_KEY. S3-compatible auth model. IAM policies can scope permissions.
Pricing
MinIO Community is free and open source (AGPL license). AIStor is MinIO's commercial offering for AI workloads. MCP server is free open source from MinIO.
Agent Metadata
Known Gotchas
- ⚠ AGPL license has commercial use implications — review license for your deployment model
- ⚠ MinIO must be running and accessible — configure endpoint correctly for network topology
- ⚠ Large file operations (model artifacts, datasets) benefit from multipart upload — check implementation
- ⚠ Official from MinIO engineering team — well-maintained with good S3 API coverage
