Common questions

Is SkillsSafe Security Scanner safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Spec Driven Development, Remote Desktop Commander, Safe Fetch

SkillsSafe — AI Skill Security Scanner

Free, no-signup security scanner for AI agent skills. Scan any SKILL.md, MCP config, or system_prompt for threats before installing.

🌐 [skillssafe.com](https://skillssafe.com)

What Is SkillsSafe?

As AI agents become more powerful, malicious skills can steal credentials, exfiltrate data, or hijack your agent's behavior. SkillsSafe scans skill files before you install them — the same way an antivirus scans software before you run it.

Supported platforms: OpenClaw · Claude Code · Cursor · Codex · any MCP-compatible agent

Features

🔍 Security Scanner

Paste content, enter a URL, or upload a file to scan for:

Threat	Description
Credential Theft	Attempts to access API keys, tokens, or passwords
Data Exfiltration	Skills that send your data to external servers
Prompt Injection	Hidden instructions that hijack agent behavior
Shell Injection	Reverse shell or arbitrary command execution
Zero-Width Characters	Invisible Unicode characters hiding malicious instructions
Scope Creep	Skills requesting permissions beyond their stated purpose
Memory Poisoning	Attempts to corrupt agent memory or context
Privacy Risk	Unnecessary access to personal or sensitive data

Each scan returns a risk score, severity rating (SAFE / CAUTION / DANGER / CRITICAL), and a shareable report link.

👁️ Zero-Width Character Detector

Visualize invisible Unicode characters (U+200B, U+200C, U+200D, U+FEFF, etc.) hidden inside text. Attackers embed these to create prompts that look safe to humans but carry hidden instructions for AI agents.

🔌 MCP Server Integration

Native Model Context Protocol support — let your agent automatically check skill safety before installation. No API key required.

# OpenClaw (one-line setup)

openclaw mcp add https://skillssafe.com/api/mcp

Available MCP tools:

scan_url — Scan a skill by URL
scan_content — Scan skill content directly
get_report — Retrieve a full scan report

📡 REST API

Works with any agent, script, or CI/CD pipeline.
