oracle.oci-object-storage-mcp-server
An MCP server that exposes Oracle Cloud Infrastructure (OCI) Object Storage service APIs, enabling AI agents to create and manage buckets, upload and download objects, configure lifecycle policies, manage access policies, set up pre-authenticated requests, and interact with OCI's S3-compatible object storage at scale.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Object storage can contain sensitive data at scale. Bucket public access should be disabled by default. Pre-authenticated requests bypass IAM and must have minimal scope and short expiry. Customer Secret Keys for S3 compatibility are long-lived credentials requiring secure storage.
⚡ Reliability
Best When
You need to automate unstructured data storage, archival, and retrieval on OCI — particularly for AI/ML artifacts, backups, data lake layers, or distributing large files securely.
Avoid When
You need file system semantics, block storage for databases, or require sub-millisecond latency for small object operations.
Use Cases
- • Automating bucket creation and lifecycle policy configuration for data pipelines
- • Uploading AI-generated artifacts, reports, and outputs to object storage
- • Managing data retention and tiering policies programmatically
- • Generating pre-authenticated request URLs for secure temporary file sharing
- • Integrating OCI Object Storage into data lake and archival workflows
Not For
- • Block storage volumes for compute instances (use OCI Block Volume)
- • File system mounts requiring POSIX semantics (use OCI File Storage)
- • Non-OCI cloud storage migration (use OCI Storage Gateway)
- • Real-time streaming data ingestion (use OCI Streaming)
Interface
Authentication
Supports both OCI native auth and S3-compatible auth (Customer Secret Keys). Bucket policies and IAM policies work together. Pre-authenticated requests enable unauthenticated access to specific objects.
Pricing
Archive tier offers lowest storage cost with retrieval delay; Infrequent Access tier balances cost and retrieval speed
Agent Metadata
Known Gotchas
- ⚠ Namespace is tenancy-scoped and must be obtained before any API calls
- ⚠ Multipart upload required for objects over 100 MB — agents must handle multi-step upload
- ⚠ Object versioning must be enabled on bucket before version history is available
- ⚠ S3-compatible endpoint uses different URL format and auth than OCI native endpoint
- ⚠ Pre-authenticated requests have expiry times that must be managed carefully
