Kolbo AI MCP Server - Generate images, videos, music, speech, and sound effects from Claude Code
Claude Skills are markdown + scripts loaded into Claude Code; scanned with the same pipeline.
We found this by crawling public sources and nobody has attested to it. That is how most of the registry gets here, and it is not a mark against the artifact — it only means no authenticated act of publication is on record. An artifact can be the vendor's own and still appear here.
18 critical findings reported by cisco-skill-scanner, agent-audit-kit. The composite score alone does not reflect this — read the per-scanner reports below.
This artifact ships from 2 sources and their verdicts differ. The worst is github (Flagged). Installing from a cleaner source does not mean the others are safe — check the source you actually install from.
github: https://github.com/zoharvan12/kolbo-mcp, 315 findings
Claude Skills install to a single target, no runtime picker.
nerlo install -- @kolbo/mcp
Manual alternative: copy the skill folder into ~/.claude/skills/ so Claude Code loads it on next launch.
cp -r -- @kolbo/mcp ~/.claude/skills/
Install respects the composite badge: Clean proceeds, Caution prompts for confirmation, and Flagged is refused. Write operations require an API token.
6 of 11 scanners examined this package. The rest do not apply to it — language, ecosystem and packaging decide which analyzers can say anything, and a scanner that cannot examine an artifact reports nothing rather than passing it.

Findings in files this artifact installs stand as reported; a model re-read the rest and said which ones it believes are false positives. This is a second opinion published beside the evidence, not a correction to it: the per-scanner reports above are unchanged, every dismissed finding is still listed there at its original severity, and the score and the Flagged badge are computed from those raw severities alone. Nothing below moved them.
Out of 161 findings across every scanner that examined this package. None of the 18 findings rated critical by their scanner were dismissed.
Two keys had to turn. The model had to name a reason from a fixed list of six, and a deterministic check of ours — over which files this artifact actually installs — had to independently agree. Anything it could not corroborate is in “not reviewed” above, at full severity.
8 Agent instruction file — The match is in a file that instructs an AI coding agent — a CLAUDE.md or similar. It is documentation of intent, and our own check confirmed it is not part of what gets installed.
Rules: secrets-claude-md-env-43028, agents-encoded-payload-51, AAK-AGENT-003 and 5 more · Files: CLAUDE.md · reported by agentshield, agent-audit-kit
4 Documentation or example — The match is in documentation or sample code, confirmed by our own check to be outside the installed artifact.

These findings are in files this artifact installs and are not placeholder values. No false-positive basis can be corroborated for such a finding, so this review never dismisses one; they were not sent to the model and stand at their scanner's severity.

Artifact has critical command injection and network access vulnerabilities.
The artifact contains multiple critical command injection vulnerabilities that allow shell execution in `/repo/scripts/check-install.js`, `/repo/scripts/smoke.js`, `/repo/src/auth.js`, and `/repo/scripts/check-widget-render.js`. It also exhibits critical Server-Side Request Forgery (SSRF) in `scripts/smoke.js`, `src/apps/index.js`, and `src/index.js`, enabling network egress and potential access to internal resources. Further critical findings indicate potential credential access or broad platform permissions via `plugins/kolbo/.mcp.json` and `scripts/check-skill-tools.js`. High severity findings also point to extensive file system access and network egress capabilities.
Concern level assessed by the review: Critical. This is the review's scale, not the registry badge.
Reviewed by gemini-2.5-flash. The model sees the findings, not your code, and cannot change a score.
