PatchPilot MCP
Security scanner for vibe coders. Checks npm packages for known vulnerabilities before you install them.
What it does
PatchPilot is an MCP server that integrates with Claude Code, Cursor, and other AI coding tools. When you're about to install a package, you can ask Claude to check if it's safe first.
Example: `` You: "Check if lodash@4.17.0 is safe to use" Claude: 🚨 lodash@4.17.0 has 4 known vulnerabilities! ... 💡 Recommendation: Update to lodash@4.17.21 or later ``
Installation
Prerequisites
- Node.js 18+
- Claude Code or another MCP-compatible client
Setup
- Clone this repository:
git clone https://github.com/YOUR_USERNAME/patchpilot-mcp.git
cd patchpilot-mcp
- Install dependencies:
npm install
- Build:
npm run build
Add to Claude Code
Add to your Claude Code config (~/.claude/settings.json):
{
"mcpServers": {
"patchpilot": {
"command": "node",
"args": ["/path/to/patchpilot-mcp/dist/index.js"]
}
}
}
Or for development (without building):
{
"mcpServers": {
"patchpilot": {
"command": "npx",
"args": ["tsx", "/path/to/patchpilot-mcp/src/index.ts"]
}
}
}
Restart Claude Code after adding the config.
Usage
Once installed, ask Claude to check packages:
- "Check if express@4.17.0 is safe"
- "Is next@14.1.0 secure?"
- "Check lodash 4.17.0 for vulnerabilities"
How it works
PatchPilot uses the OSV API (Google's Open Source Vulnerabilities database) to check packages. The API is:
- Free (no API key needed)
- Fast
- Comprehensive (aggregates data from npm, GitHub, NVD, and more)
Available Tools
check_package
Check a single npm package for known vulnerabilities.
Input:
name: Package name (e.g., "lodash")version: Package version (e.g., "4.17.0")
Output:
- Vulnerability count and severity breakdown
- Details of each vulnerability
- Recommended fix version
