Implementation Reference

tools/daemonset.py:27-56 (handler)

The main handler function for the 'daemonset_create' tool. It is decorated with @mcp.tool() which registers it as an MCP tool, @use_current_context for context management, and @check_readonly_permission for access control. The function creates a Kubernetes DaemonSet in the specified namespace using the provided parameters.
