Overview

This server provides tools to interact with the OCI Object Storage resources. It includes tools to help with managing object storage configurations.

Running the server

STDIO transport mode

uvx oracle.oci-object-storage-mcp-server

HTTP streaming transport mode

ORACLE_MCP_HOST=<bind_host> \
ORACLE_MCP_PORT=<port> \
ORACLE_MCP_BASE_URL=<public_base_url> \
OCI_REGION=<region> \
IDCS_DOMAIN=<idcs_domain> \
IDCS_CLIENT_ID=<client_id> \
IDCS_CLIENT_SECRET=<client_secret> \
IDCS_AUDIENCE=<audience> \
uvx oracle.oci-object-storage-mcp-server

Register ${ORACLE_MCP_BASE_URL}/auth/callback in the OCI IAM confidential application. If IDCS_REQUIRED_SCOPES is unset, the default is openid profile email oci_mcp.object_storage.invoke.

Tools

Tool Name	Description
get_namespace	Get the object storage namespace for the tenancy
list_buckets	List object storage buckets in a given compartment
get_bucket_details	Get details for a specific object storage bucket
