OCI OpenSearch MCP Server
Overview
This server provides MCP tools for interacting with the Oracle Cloud Infrastructure (OCI) OpenSearch control plane.
It exposes a focused, SDK-backed set of OpenSearch cluster lifecycle operations and work-request tracking tools for use by MCP clients.
Authentication
The server uses standard OCI configuration and signer behavior. Configure OCI credentials with an OCI config file and profile before starting the server. The active OCI identity's IAM permissions determine which OpenSearch operations are allowed.
Running the server
STDIO transport mode
uvx oracle.oci-opensearch-mcp-server
Local development from source
From this project directory, use one of these commands:
uv run oracle.oci-opensearch-mcp-server
uvx --from . oracle.oci-opensearch-mcp-server

Request body guidance
Mutation tools use OCI Python SDK-style request bodies with snake_case field names.
For detailed payload conventions and examples, read the bundled
resource://oci-opensearch-api-guide resource from your MCP client.
update_opensearch_cluster accepts a non-empty partial update_details body.
display_name is optional and only needed when renaming a cluster.
To discover existing clusters, use list_opensearch_clusters rather than create_opensearch_cluster.
Most mutating operations are asynchronous and return an opc_work_request_id. Use
get_work_request and list_work_requests to inspect status. MCP agents should not
poll continuously by default: after an async response, they may call get_work_request
once for an immediate status snapshot, then ask the user before repeated checks.
For create, resize, and backup operations, MCP sends an opc_retry_token; callers may
provide one explicitly, otherwise MCP generates and returns a deterministic token for the
same logical request.
An empty list_work_requests match is explicit: {"items": [], "count": 0}.
Notes
⚠️ NOTE: All actions are performed with the permissions of the configured OCI profile. Use least-privilege IAM policies, secure credential handling, and safe operational practices.
