Quick Start

Install

pip install ovirt-engine-mcp-server

Or from source:

git clone https://github.com/imjoey/ovirt-engine-mcp-server.git
cd ovirt-engine-mcp-server
pip install -e .

Configure

Environment variables (recommended):

export OVIRT_ENGINE_URL="https://ovirt-engine.example.com"
export OVIRT_ENGINE_USER="admin@internal"
export OVIRT_ENGINE_PASSWORD="your-password"

Or create a config.yaml:

OVIRT_ENGINE_URL: https://ovirt-engine.example.com
OVIRT_ENGINE_USER: admin@internal
# OVIRT_ENGINE_PASSWORD should be set via environment variable

Run

ovirt-engine-mcp

Error Handling

All errors return structured JSON with error code, message, and retry guidance:

Retry strategy: Only retry on retryable: true errors. Use exponential backoff (1s → 2s → 4s). NOT_FOUND and PERMISSION_DENIED require user intervention.

Available Tools

186 tools across 27 categories. Each reference file is self-contained with its own index:

Quick Category Reference

Common Workflows

Create VM from Template

1. template_list → find template ID
2. cluster_list → find cluster ID
3. template_vm_create(name, template, cluster, ...)
4. vm_start(name_or_id)

Migrate VM

1. vm_list(status="up") → find running VM
2. host_list() → find target host
3. vm_migrate(name_or_id, target_host)

Create Snapshot & Restore

1. snapshot_create(name_or_id, description="before-patch")
2. ... perform changes ...
3. snapshot_restore(name_or_id, snapshot_id)  # if needed

Storage Health Check

1. storage_list → list all domains
2. storage_stats(name_or_id) → check each domain
3. event_errors → check for storage-related errors

RBAC Audit

1. permission_list(resource_type="cluster", resource_id="...") → list perms
2. user_list → list users
3. tag_list → list tags
