VCF Agentic AI Hub (Code Assist) MCP Server Fling

by // 1 Comment

Creating scripts to help automate repetitive tasks or generate reports is a common need for every VMware administrator, and with Agentic coding tools like Claude Code, Codex, and Cursor, to name a few, the barrier to entry has been significantly lowered. In fact, when I spoke with attendees at VMware Explore Las Vegas 2026 about their use of coding agents, I saw a dramatic shift compared to the previous year, from maybe 20% to now over 80%!

However, one key challenge you may have experienced when using AI models (LLMs) is that they can still hallucinate and make up a non-existent REST API endpoint or PowerCLI cmdlet. LLMs are designed to always provide an answer, even when that answer may be wrong.

To help address this challenge and provide modern LLMs with the required VCF context for developing scripts and automation, a new Fling has just been released called VCF Agentic AI Hub (VCF-AI), which is delivered as a standalone virtual appliance. VCF-AI includes a VCF Code Assist MCP Server that currently supports code generation for the following VCF SDKs:

  • VCF PowerCLI
    • vCenter Server
    • vSAN
    • VCF Operations
    • SDDC Manager
    • NSX
    • vSphere Supervisor
    • HCX
    • SRM
  • VCF Python SDK
    • vCenter Server
    • vSAN
    • vSAN Data Protection
    • VCF Operations
    • VCF Installer
    • SDDC Manager
    • NSX
    • vSphere Supervisor
    • VCF Operations for Networks
    • Log Management
    • VCF Fleet and SDDC LCM

VCF-AI includes all the OpenAPI specifications and documentation for the two SDKs, which cover a number of VCF components along with skill files that have been created by VCF Engineering to allow users to easily create automation using their favorite Agentic coding agent.

Automate Inventory of vSphere Supervisor Clusters & vSphere Kubernetes Service (VKS) Guest Clusters

by // Leave a Comment

As customers begin planning their upgrade to VMware Cloud Foundation (VCF) 9.1, vSphere Supervisor and vSphere Kubernetes Service (VKS) have been coming up more frequently in upgrade discussions.

Before you can determine the applicable upgrade path, it is important to understand what has been deployed. Depending on your environment, you may have multiple vSphere Supervisor Clusters running different Supervisor versions, VKS Service versions, and VKS Guest Cluster versions, which can make gathering a complete inventory challenging.

To help simplify the collection of information, I have created a small PowerCLI script called Get-vSphereSupervisorAndVKSInventory.ps1 (I actually had to create the initial base with me verifying specific cmdlets to provide to AI because it went on wild tangent when asked to create me such a script) which will automatically inventory your vSphere Supervisor and VKS deployments. At first, I was hoping AI could

VCF 9.1.1 - OCuLink External Graphics (eGPU) Dock with integrated PSU for GPU Passthrough with VKS

by // 2 Comments

For those who have been following my VCF Private AI Services (PAIS) exploration with deploying my own AI models and using them with Coding Agents running on VCF, I have found that these AI workloads can really push the thermals on my NVIDIA RTX 4000 running inside my Minisforum MS-A2, eventually causing the GPU to start throttling.

Earlier this year, I had shared a solution from a colleague who wanted to leverage a more capable GPU with vSphere Kubernetes Service (VKS) and was able to externalize the GPU using an OCuLink-based eGPU dock that is also compatible with the MS-A2.

I was initially going to use the same eGPU solution, which would have also required purchasing a separate PSU to power the GPU. While looking at my options, I came across another OCuLink eGPU dock (AG01) from Aoostar that had an integrated PSU (up to 800W), was plug-and-play ready, and certainly had a much cleaner aesthetic design.
