Virtualbox MCP Server (usemanusai/Virtualbox-mcp-server) is an MCP server listed on the M8ven Trust Index. It scores 54 out of 100, grade D. It declares 92 tools. No publisher has claimed this listing.
A Model Context Protocol server for managing Virtualbox and Vagrant virtual machines via a TypeScript interface. It enables users to programmatically create new VMs and monitor their status through simple JSON-RPC tools.
Caution. Specific findings reduced this grade. They are listed on the page. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

The grade above is for the source repository. Registries can serve a different version, so we mark the ones we were not able to read.
These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.
create_vmCreate a new Vagrant VM
get_vm_statusGet the status of a specific Vagrant VM
list_vmsList all managed VMs and their statuses
destroy_vmDestroy a Vagrant VM (force)
exec_commandExecute a shell command inside a VM
upload_fileUpload a file from host to VM
search_filesSearch for files inside the VM (using grep)
configure_syncConfigure file synchronization and watchers
sync_statusGet the current alignment status of the sync engine
resolve_conflictResolve a file sync conflict
create_dev_vmCreate and configure a development VM with Vagrant (advanced)
ensure_dev_vmEnsure development VM is running, create if it doesn't exist
exec_with_syncExecute a command in the VM with file synchronization before and after
run_background_taskRun a command in the VM as a background task
setup_dev_environmentInstall language runtimes, tools, and dependencies in the VM
install_dev_toolsInstall specific development tools in the VM
configure_shellConfigure shell environment in the VM
sync_to_vmSync files from host to VM
sync_from_vmSync files from VM to host
tail_vm_logReads the last N lines of a specific file inside the VM (e.g., /var/log/syslog, /var/log/nginx/error.log). Essential for debugging service failures.
get_task_outputRetrieves the stdout and stderr buffers of a specific background task started via run_background_task. Essential for monitoring long-running jobs.
grep_log_streamSearches within a log file for a specific pattern. Locates events within active log streams.
snapshot_saveCreates a lightweight Vagrant snapshot. Use before risky operations to enable rollback if something breaks.
snapshot_restoreReverts the VM to a specific named snapshot. Enables rapid recovery without destroying and rebuilding the VM.
snapshot_listLists all available snapshots for a VM.
snapshot_deleteDeletes a specific snapshot from a VM.
list_processesReturns a structured list of running processes in the VM (like ps aux). Use to verify service health and resource usage.
kill_processSends a signal (SIGTERM/SIGKILL) to a specific process in the VM. Required to stop runaway tasks or stuck servers.
check_vm_portVerifies if a port is listening in the VM and optionally accessible from the host. Differentiates 'App failed' from 'Port forwarding failed'.
get_vm_dashboardReturns a comprehensive dashboard with VM status, resource usage (CPU/RAM/Disk), active background tasks, and recent logs.
start_downloadStarts a tracked file download operation. Returns an operation_id that MUST be used with `wait_for_operation`.
get_operation_progressGets real-time progress of a specific operation (bytes downloaded, percentage, ETA).
wait_for_operationBlocks execution until an operation completes OR times out. CRITICAL: Use this after starting any long-running task.
cancel_operationCancels a running operation.
list_active_operationsLists all currently running operations.
scan_system_healthChecks system health (disk space, memory) and identifies potential 'Zombie' VMs. Can optionally perform a security scan on a specific VM.
cleanup_zombiesSafely cleans up identified Zombie VMs. REQUIRES explicit list of VM names to avoid accidents.
sequentialthinkingA detailed tool for dynamic and reflective problem-solving. MUST be used between steps to analyze state. Features: Checks resources (RAM/Disk) before VM creation, verifies hypothesis, allows branching/backtracking. Parameters: - thought: The current thinking step. MUST include technical checks (e.…
set_display_modeControls Headless vs GUI state of a VM.
atomic_transaction_execExecutes a command with auto-snapshot safety. Reverts on failure if rollback_on_fail is true.
sentinel_awaitWait until a specific condition is met in the VM (port, file, log, or service).
forensic_blackbox_captureAggregates a diagnostic bundle (logs, processes, system state) for failure analysis.
resize_vm_resourcesModifies VM CPU/RAM/GUI settings. Triggers a reboot if the VM is running.
package_boxExports the VM to a portable .box file using `vagrant package`.
inject_secretsSecurely injects environment variables into the VM's .profile. Parameters are redacted from MCP logs.
audit_securityScans the VM for common security issues (open ports, weak ssh config).
Disclosed vulnerabilities in this server's declared npm dependencies (via OSV). Whether each is reachable depends on the installed versions.

LOG_LEVEL"": "info",Tool annotations
No tools have read-only/destructive annotations
Add readOnlyHint or destructiveHint annotations to every tool so hosts can warn users before invoking.
All four hints declared on every tool
92/92 tools missing one or more hints — create_vm (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); get_vm_status (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); list_vms (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +89 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
