What is the Vulnerability MCP server?

A developer-centric security toolkit that unifies multiple scanning engines (including a custom, AST-based Python scanner and Semgrep) to find OWASP Top 10 vulnerabilities. Designed for seamless integration into development workflows and. The vulnerability mcp server wraps that behind the Model Context Protocol, so an assistant can use it rather than through you.

What it actually does

  • Unified Workflow — Integrates multiple scanning engines into a single, cohesive CLI interface
  • Dual-Engine Philosophy —
  • Custom Engine — A high-fidelity, Python-specific scanner built from the ground up to detect OWASP Top 10 vulnerabilities with low false positives. Uses AST parsing for deep code analysis and integrates pip-audit for dependency checking
  • Semgrep Engine — An integrated wrapper around the industry-standard Semgrep tool, providing broad, fast, multi-language scanning capabilities based on a vast community-driven ruleset
  • Developer-Centric — Designed for ease of use by developers, providing clear, actionable feedback
  • Educational — Each finding from the Custom Engine includes an explanation of the vulnerability, potential attack scenarios, and remediation guidance, making it a valuable learning tool

Adding it to your client

Installation goes through your MCP client rather than a global install: point it at vulnerability-scanner on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

When to reach for it

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call.

SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the vulnerability mcp server does with a few real requests.

How to install the Vulnerability MCP server

{
  "mcpServers": {
    "vulnerability-scanner": {
      "command": "uvx",
      "args": ["vulnerability-scanner"]
    }
  }
}

Add to claude_desktop_config.json, then restart Claude Desktop.
