VirtFusion MCP Server

A Model Context Protocol (MCP) server that wraps the VirtFusion virtualization control panel API. This enables AI assistants like Claude to manage VirtFusion infrastructure through natural language.

Features

• 84 tools covering the entire VirtFusion Admin API
• Server lifecycle management (create, build, delete, suspend, unsuspend)
• Power control (boot, shutdown, restart, poweroff)
• Network management (IPv4, whitelist, firewall, traffic)
• User management with external relation ID support
• Self-service operations (credit, resource packs, hourly profiles)
• Infrastructure management (hypervisors, IP blocks, packages, DNS)
• Backup and media management
• SSH key management
• Automatic API endpoint drift detection

Prerequisites

• Node.js 22 or later
• VirtFusion panel with Admin API access
• An API token generated from your VirtFusion admin panel

API Endpoint Sync

This project includes tooling to detect when VirtFusion adds new API endpoints:

# Extract endpoints from the current OpenAPI spec
npm run extract-endpoints > endpoint-manifest.json

# Check for drift between spec and manifest
npm run check-endpoint-drift

The endpoint-sync workflow runs weekly and on any changes to openapi.yaml, creating an issue if drift is detected.

Adding new tools when VirtFusion updates their API

1. Download the updated openapi.yaml from VirtFusion docs
2. Run npm run check-endpoint-drift to see what changed
3. Implement new tools in the appropriate src/tools/*.ts module
4. Update the manifest: npm run extract-endpoints > endpoint-manifest.json
5. Commit everything together
