nutanix-mcp 1.0.0

Nutanix MCP — Model Context Protocol server for Nutanix Prism Element, Prism Central, and Move

Nutanix MCP

Ask GitHub Copilot questions about your Nutanix environment in plain English — VMs, hosts, storage, networking, alerts, tasks, protection domains, resource utilization, migration plans, and more — directly from VS Code.

Supports Prism Element (PE), Prism Central (PC), and Nutanix Move — with per-cluster, per-PC, and per-Move-appliance credentials stored securely in your OS keyring (Windows Credential Manager / macOS Keychain / Linux Secret Service).

Requirements

• Python 3.10+
• VS Code
• GitHub Copilot + Copilot Chat extensions

Quick start

# 1. Install
pip install nutanix-mcp

# 2. Create a folder for your inventory, navigate to it, and run the wizard
mkdir my-nutanix && cd my-nutanix
nutanix-mcp configure

The wizard will:

• Verify Python 3.10+ is active
• Install / update all dependencies
• Register your Prism Element cluster(s), Prism Central instance(s), and Move appliance(s) in inventory.yaml
• Store credentials securely in the OS keyring — no plain-text passwords anywhere
• Write .vscode/mcp.json pointing VS Code at the server (no credentials in this file)

# 3. Open the folder in VS Code
code .

In VS Code, open Copilot Chat, switch to Agent mode, and start asking questions.

Already set up? Re-run nutanix-mcp configure at any time to add new clusters, PC instances, or Move appliances, and to update credentials.

Configuration

Credential storage

Credentials are stored in the OS keyring under the service name nutanix-mcp. Key format:

Entity	Keyring key examples
PE cluster (default)	pe.default.username, pe.default.password
PE cluster (override)	pe.CLUSTER-NAME.username, pe.CLUSTER-NAME.password
Prism Central	pc.PC-NAME.api_key (preferred) or pc.PC-NAME.username / pc.PC-NAME.password
Move appliance	move.MOVE-NAME.username, move.MOVE-NAME.password

Lookup uses named keyring entries and PE default keyring fallback where applicable.

Cluster inventory — inventory.yaml

Register your instances here. Edit directly or re-run nutanix-mcp configure.

prism_central:
  - name: PROD-PC-1
    pc_host: 192.168.1.50

clusters:
  - name: PROD-CLUSTER-1
    pe_host: 192.168.1.100
  - name: PROD-CLUSTER-2
    pe_host: 192.168.1.200

move_instances:
  - name: PROD-MOVE-1
    move_host: 192.168.1.75

• name — label used in prompts and tool parameters (pc_name, cluster_name, move_name)
• Single entry → selected automatically; multiple entries → specify the name in your prompt

VS Code — .vscode/mcp.json

Generated by nutanix-mcp configure. Contains no credentials:

{
  "servers": {
    "nutanix-mcp": {
      "type": "stdio",
      "command": "nutanix-mcp",
      "env": {
        "NUTANIX_MCP_INVENTORY": "${workspaceFolder}/inventory.yaml"
      }
    }
  }
}

Usage

Switch Copilot Chat to Agent mode and ask in plain English:

List all VMs and their power state
How much free storage does the cluster have?
Show me any critical alerts
What tasks are currently running?
Show resource utilization for the cluster over the last hour
Get CPU and memory stats for VM <uuid>
Which hosts are in the cluster and what model are they?
List all protection domains
Show migration plans on the Move appliance
Which VMs are currently being seeded?

Target a specific cluster, PC instance, or Move appliance by name:

List all hosts from cluster PROD-CLUSTER-1
Show VMs on PROD-CLUSTER-2
List all VMs managed by PC PROD-PC-1
Show subnets across all clusters from PROD-PC-1
List migration plans on PROD-MOVE-1

Copilot calls list_inventory automatically when needed to discover available entries.

Notes

• All tools are read-only — no changes are made to your Nutanix environment
• PE tools use the Prism Element v2.0 REST API (per-cluster, port 9440)
• PC tools use the Prism Central v4.0 REST API (cross-cluster, port 9440); alert listing uses the v2.0 gateway at /PrismGateway/services/rest/v2.0/alerts
• Move tools use the Move v2 REST API (port 443)
• PC tools use extId as the entity identifier; use values from list_* calls as input to get_* calls
• Stats metrics are in ppm (parts per million); divide by 10,000 to convert to a percentage
• Transport is stdio — the server runs locally and is managed by VS Code
