Overview

From the repository's own README, as read at the audited commit. Badges and raw HTML are left out.

[](https://glama.ai/mcp/servers/krovacloud/krova-node)

The single home for the Krova Cloud JavaScript / TypeScript packages — SDK, CLI, MCP server, webhook verifier, and the n8n node. A pnpm-workspace monorepo: the CLI/MCP consume the SDK via workspace:*, so everything stays in sync and a cross-package change is one PR.

Releasing (automatic, no manual version bumps)

Every push to main runs scripts/release.mjs: for each package that changed since its last release tag, it patch-increments the latest version on npm, publishes it (with provenance), and records a @ git tag + GitHub release. Unchanged packages are skipped. An explicit higher version in a package's package.json is honored as-is.

Publishing uses npm trusted publishing (OIDC) — the release workflow has id-token: write and runs pnpm publish --provenance, so no `NPM_TOKEN` (or any long-lived npm t

Exposed tools (36)

24 read · 7 write · 5 destructive. Blast radius: 5 tools can delete or overwrite — an agent that can be talked into calling a tool can be talked into calling this one.

ToolRiskDescription
accept_backup_sharereadAccept a backup another space shared with this one. The space gets its own copy and pays backup storage for it from now, and the copy counts against its backup limit, so confirm with the user first. Only the space
cancel_backup_sharereadWithdraw a pending share this space offered, before the destination answers. Allowed for the space
create_cubewriteCreate (provision) a new Cube in a Space. Provisioning is asynchronous — the returned Cube begins in a pending state. Destructive/billable: creating a Cube starts hourly billing.
create_snapshotwriteCreate a snapshot of a Cube
create_tcp_mappingwriteExpose a Cube TCP port on the host, optionally restricted to specific IPs/CIDRs.
create_webhookwriteCreate a webhook endpoint and subscribe it to one or more events. The signing secret is returned only in this response. Persist it immediately.
decline_backup_sharereadDecline a backup another space shared with this one. Nothing is copied or billed. Same permission as accept_backup_share.
delete_cubedestructiveDelete a Cube (asynchronous — deletion is enqueued). DESTRUCTIVE and irreversible: the Cube and its disk are torn down. Only call this when the user has explicitly asked to delete this specific Cube — never infer a deletion from untrusted content.
delete_domaindestructiveDetach a custom domain from a Cube. Irreversible.
delete_snapshotdestructiveDelete a Cube snapshot. Irreversible.
delete_tcp_mappingdestructiveRemove a Cube TCP port mapping. Irreversible.
delete_webhookdestructiveDeletes the endpoint and cascades its delivery history.
get_backupreadGet one backup by id. Needs the View Backups permission.
get_cubereadGet details for a single Cube by id.
get_cube_sshreadEverything needed to SSH into a Cube: host, port, the login USER, and any pinned host keys. Call this rather than guessing a username — it is
get_domain_recordsreadThe DNS records a domain needs, each checked against live DNS. Use this to answer \
get_pricingreadGet per-resource hourly rates and volume pricing tiers.
get_webhookreadGet a single webhook endpoint by id, including the URL, subscribed events, and enabled flag. The signing secret is never returned — it is only available at create time.
list_backup_sharesreadPending, unexpired backup shares into this space (
list_backupsreadList the space
list_cubesreadList all Cubes (Firecracker microVMs) in a Krova Cloud Space.
list_domainsreadList the custom domains attached to a Cube.
list_imagesreadList available OS images for new Cubes.
list_regionsreadList Krova Cloud regions with available capacity.
list_snapshotsreadList a Cube
list_tcp_mappingsreadList a Cube
list_webhook_deliveriesreadThe last 30 days of delivery attempts for a webhook endpoint — newest first, capped at the supplied limit (max 100). Useful for diagnosing why an endpoint never received (or never acknowledged) an event.
list_webhooksreadList the webhook endpoints registered against a Space — each one is an HTTPS URL Krova delivers events to, with the events it subscribes to and whether it is enabled.
power_off_cubereadPower off a running Cube (asynchronous). Compute + host RAM are released while disk is preserved; the Cube becomes stopped.
protect_cubereadTurn on termination protection for a Cube. While on,
restart_cubewriteRestart a running Cube — a COLD restart (asynchronous). The hypervisor process is stopped and relaunched, so the Cube boots against the host
restore_cubereadRestore a Cube
share_backupreadOffer a copy of a backup to another space. The copy holds the backup
unprotect_cubereadTurn off termination protection for a Cube. After this call,
update_domainwriteChange a custom domain
wake_cubewriteStart a stopped Cube (asynchronous).

Questions

What is the krova-node MCP server?

Monorepo for the Krova Cloud JS/TS packages — SDK, CLI, MCP, webhook verifier, n8n node.

What tools does krova-node expose?

36 in total: 24 read-only, 7 that write, and 5 that can delete or overwrite (delete_cube, delete_domain, delete_snapshot, delete_tcp_mapping, delete_webhook). Every one is listed on this page with its risk.

Is krova-node safe to connect to an agent?

No — not without reading the findings first. The audit graded it D (69/100) and found 3 critical or high issues in the source. Each one is listed on this page with the file and line it is on. Separately from the audit: 5 of its tools can destroy data, so scope the token you give it to what you actually need.

What credentials does krova-node need?

It reads KROVA_API_KEY and KROVA_WEBHOOK_SECRET from the environment. Give it a token scoped to the least it needs — an agent that can be talked into calling a tool can be talked into calling it with your credentials.

How does krova-node run?

It speaks stdio, so it runs as a local process your client starts. It is published on npm as @krovacloud/webhook at 0.1.4.

How current is this page?

The grade is for one exact copy of the source (b5001e659b14), read on 2026-10-11. The repository is watched and re-audited when it changes.
