AI-assisted monitoring and capacity planning for VMware Aria Operations (vRealize Operations) via the Model Context Protocol (MCP).

## Overview

`vmware-aria` exposes 27 MCP tools for interacting with Aria Operations through natural language AI agents (Claude Code, Cursor, Goose, etc.):

| Category | Tools | Type |
|----------|-------|------|
| **Resources** | list, get, metrics, health badge, top consumers | Read-only (5) |
| **Alerts** | list, get, acknowledge, cancel, definitions | Read + 2 Write (5) |
| **Alert Definitions** | symptom definitions, create, enable/disable, delete | Read + 3 Write (4) |
| **Capacity** | overview, remaining, time-remaining, rightsizing | Read-only (4) |
| **Reports** | definitions, generate, list, get, delete | Read + 2 Write (5) |
| **Anomaly** | list anomalies, risk badge | Read-only (2) |
| **Health** | platform health, collector groups | Read-only (2) |

**Total**: 27 tools — 20 read-only, 7 write

## Quick Start

```bash
# Install
uv tool install vmware-aria

# Configure
mkdir -p ~/.vmware-aria
cat > ~/.vmware-aria/config.yaml << 'EOF'
targets:
  prod:
    host: aria-ops.example.com
    username: admin
    port: 443
    verify_ssl: true
    auth_source: LOCAL
default_target: prod
EOF

# Set password (never in config.yaml)
echo "VMWARE_ARIA_PROD_PASSWORD=your_password" > ~/.vmware-aria/.env
chmod 600 ~/.vmware-aria/.env

# Verify setup
vmware-aria doctor
```

## CLI Examples

```bash
# List top CPU consumers
vmware-aria resource top --metric cpu|usage_average --top 10

# Check active CRITICAL alerts
vmware-aria alert list --criticality CRITICAL

# Acknowledge an alert
vmware-aria alert acknowledge <alert-id>

# Fetch 4-hour CPU + memory metrics for a VM
vmware-aria resource metrics <vm-id> --metrics cpu|usage_average,mem|usage_average --hours 4

# Check cluster capacity
vmware-aria capacity remaining <cluster-id>
vmware-aria capacity time-remaining <cluster-id>

# Find rightsizing opportunities
vmware-aria capacity rightsizing

# Check Aria platform health
vmware-aria health status
vmware-aria health collectors
```

## MCP Setup (Claude Code)

After `uv tool install vmware-aria`, add to `~/.claude.json`:

```json
{
  "mcpServers": {
    "vmware-aria": {
      "command": "vmware-aria",
      "args": ["mcp"],
      "env": {
        "VMWARE_ARIA_CONFIG": "~/.vmware-aria/config.yaml"
      }
    }
  }
}
```

> **v1.5.15+** uses the single-command form `vmware-aria mcp`. The legacy
> `vmware-aria-mcp` console script is still kept for backward compatibility.
> If you must use `uvx --from vmware-aria vmware-aria mcp` (no install) and hit
> `invalid peer certificate: UnknownIssuer` behind a corporate TLS proxy, set
> `UV_NATIVE_TLS=true` or use the recommended `vmware-aria mcp` form above.

Then use natural language:
- *"Show me the top 10 CPU consumers right now"*
- *"List all CRITICAL alerts and acknowledge them"*
- *"How long until the prod cluster runs out of memory?"*
- *"Which VMs are over-provisioned? Show rightsizing recommendations"*
- *"Are there any anomalies on vm-web-01?"*

## Authentication

Aria Operations uses **vRealizeOpsToken** authentication:

```
POST /suite-api/api/auth/token/acquire
{"username": "admin", "password": "...", "authSource": "LOCAL"}
→ {"token": "abc123", "validity": 1765182896000}  # validity = expiry epoch ms

Subsequent requests: Authorization: vRealizeOpsToken abc123
```

Tokens have a 6-hour sliding validity (extended on each call, per the official spec); the client re-acquires automatically 60 seconds before expiry. The `validity` field is the expiry timestamp in epoch milliseconds, not a duration.

## Security

- Passwords loaded from env vars or `.env` file, never from `config.yaml`
- Write operations (alert acknowledge/cancel, alert definition management, report generate/delete) audit-logged to `~/.vmware/audit.db` (MCP, via vmware-policy) and `~/.vmware-aria/audit.log` (CLI)
- API responses sanitized (control chars stripped, 500-char limit) to prevent prompt injection
- Supports self-signed certificates (`verify_ssl: false`) for lab environments
