CVE Checking

The server uses the OSV (Open Source Vulnerabilities) API to check npm packages for known security vulnerabilities. This helps you make informed decisions before installing packages.

Usage Examples

Check a single package:

{
	"tool": "check_package_cves",
	"arguments": {
		"packageName": "express",
		"version": "4.17.1"
	}
}

Check multiple packages at once:

{
	"tool": "check_packages_bulk_cves",
	"arguments": {
		"packages": [
			{ "name": "express", "version": "4.17.1" },
			{ "name": "lodash", "version": "4.17.20" },
			{ "name": "axios" }
		]
	}
}

Building and Running

1. Install dependencies:

npm install

2. Build the project:

npm run build

3. Run the MCP server:

node build/index.js

Usage

Add to .vscode/mcp.json to configure the MCP server in your development environment.

{
	"servers": {
		"cve-checker-mcp": {
			"type": "stdio",
			"command": "node",
			"args": ["./build/index.js"]
		}
	},
	"inputs": []
}

Integration

This MCP server can be integrated with any MCP-compatible client to provide CVE checking capabilities before installing npm packages.
