KubeBlocks Cloud MCP Server

The KubeBlocks Cloud MCP Server is a Model Context Protocol (MCP) server that provides seamless integration with KubeBlocks Cloud APIs, enabling AI assistants to interact with KubeBlocks Cloud resources through a standardized tool-calling interface.

Use Cases

• Automating KubeBlocks Cloud resource management
• Retrieving and analyzing data from KubeBlocks Cloud environments
• Building AI-powered tools that interact with the KubeBlocks Cloud ecosystem
• Enabling AI assistants to provision and manage database instances

Features

• MCP-based API for accessing KubeBlocks Cloud resources
• Secure authentication via KubeBlocks Cloud API key and secret
• Support for common KubeBlocks Cloud resources:
  • Organizations
  • Environments
  • Instances
  • Backups
• Internationalization support via translation helpers
• Secure communication through StdioServer

Prerequisites

1. Go 1.20+ (compatible with the MCP-Go package)
2. KubeBlocks Cloud API credentials - you'll need an API key name and secret

Installation

Build from Source

git clone https://github.com/apecloud/kb-cloud-mcp-server.git
cd kb-cloud-mcp-server
go mod tidy
go build -o kb-cloud-mcp-server ./cmd/server

Usage with VS Code

Add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open User Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace to share the configuration with others.

Note that the mcp key is not needed in the .vscode/mcp.json file.
