Installation
To install the Kubernetes MCP server, run:
go install github.com/cautiousseash/kai/cmd/kai
Integration with Claude for Desktop
code ~/Library/Application\ Support/Claude/claude_desktop_config.json
Add the server to your Claude for Desktop configuration by editing claude_desktop_config.json:
{
"mcpServers": {
"kubernetes": {
"command": "/path/to/kubernetes-mcp-server-binary"
}
}
}
