SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

SkillSync MCP solves the risk of installing untrusted Claude Code/AI coding assistant skills by forcing a full security scan of GitHub skill content before installation.

Core Features & Use Cases

  • Marketplace search: Find SkillsMP skills by keyword or AI-powered semantic search.
  • Security Scan & Risk Gating: Detect prompt injection, reverse shells, credential theft, supply chain attacks, and more using 60+ threat patterns, with critical threats permanently blocked.
  • Install/Uninstall & Deep Audit: Install safely into ~/.claude/skills/, remove skills cleanly, and re-audit installed skills on demand.
  • Startup verification & live sync: Hash and watch installed skills for changes to keep the local registry consistent.

Quick Start

Ask your AI assistant to install a skill by scanning its GitHub URL first, for example: Install the commit skill from https://github.com/user/repo/tree/main/skills/commit.

FAQPage Schema
How do I scan GitHub skills for prompt injection before installing them in Claude Code?

To safely install AI coding skills from GitHub, use a security-gated MCP workflow that scans content for prompt injection and supply chain attacks before copying files. This approach enforces URL allowlisting with SSRF prevention to ensure only verified skill content reaches your local directories.

What is security-gated skill installation for MCP clients?

Security-gated skill installation for MCP clients is a workflow that forces a full security scan of GitHub skill content before allowing installation. It uses risk-level gating to permanently block critical threats, ensuring untrusted AI coding assistant skills are verified before reaching your local environment.

How do I safely install Claude Code skills from a GitHub URL?

You can safely install Claude Code skills by providing the GitHub URL to a security-gated MCP client. The client scans the repository content for threats, applies risk-level gating, and then installs the verified skill into either your global ~/.claude/skills/ or project .claude/skills/ directory.

Can I search the SkillsMP marketplace and automatically scan results for security risks?

Yes, you can search the SkillsMP marketplace by keyword or semantic search and use a safe search mode that automatically scans the results. This mode detects prompt injection, reverse shells, and credential theft using 60+ threat patterns before any installation occurs.

Does installing MCP skills from GitHub require SSRF prevention measures?

Yes, installing MCP skills from GitHub requires SSRF prevention measures like URL allowlisting to block malicious internal network requests. A security-gated installation workflow enforces these protections alongside content hashing and prompt-output sanitization to keep the local registry safe.

How do I audit and monitor installed Claude Code skills for unauthorized changes?

To audit installed Claude Code skills, you can use an MCP tool to re-audit skills on demand and hash their content for startup verification. This enables live sync watching to detect unauthorized changes and keep the local skill registry consistent.
