Overview

What is OceanBase Kubernetes Control Tool (okctl) MCP Server?

It is an MCP server implementation that exposes OceanBase cluster, tenant, and backup policy management tools via the MCP protocol by calling the underlying okctl command-line tool. It is intended for users who manage OceanBase clusters on Kubernetes.

How to use OceanBase Kubernetes Control Tool (okctl) MCP Server?

Requires Python 3.10+, the uv package manager, and a properly installed and configured okctl and Kubernetes environment. Configure the server in your MCP client JSON, setting the OB_CLUSTER_PASSWORD environment variable. Optional command-line arguments include --tools to enable specific modules, --use_sse for SSE transport, and --port to set the SSE port (default 8000).

Key features of OceanBase Kubernetes Control Tool (okctl) MCP Server

  • Cluster management: create, delete, view, scale, update, upgrade clusters
  • Tenant management: create, delete, view, scale, update, upgrade, change password, activate standby, replay logs, switchover
  • Backup policy management: create, delete, view, update, pause, resume policies
  • SQL operations: configure database connection and execute SQL queries
  • Component management: list, install, and update components

Use cases of OceanBase Kubernetes Control Tool (okctl) MCP Server

  • Automate OceanBase cluster lifecycle operations on Kubernetes
  • Manage tenants including primary/standby switchover and log replay
  • Configure and control backup policies for OceanBase clusters
  • Execute SQL queries against OceanBase databases programmatically
  • Install and update OceanBase-related components

Frequently asked questions

1

What are the runtime dependencies?

Python 3.10 or higher, uv, okctl (properly installed and configured), and a Kubernetes environment with access to OceanBase clusters.

2

Where does the server store data and how is authentication handled?

Data resides in the Kubernetes cluster where OceanBase is deployed. Authentication for SQL operations uses the environment variable `OB_CLUSTER_PASSWORD` or a password parameter in the connection configuration.

3

Which transports are supported?

By default it uses stdio transport. You can enable Server-Sent Events (SSE) transport with the `--use_sse` flag and optionally set a custom port.

4

Are there any known limits?

Some operations (e.g., deleting clusters, deleting tenants) may be irreversible; proceed with caution. SQL queries require precise prompts to avoid errors. It is recommended to perform backups before executing important operations.

5

What tools can be enabled selectively?

Use the `--tools` argument with a comma‑separated list from: `all`, `clusters`, `tenants`, `backup_policy`, `components`, `sql`. Default is all tools enabled.
