Security Report

5.2
Moderate5.2Moderate Risk

This is a well-designed MCP server with strong security practices. Authentication via API key is properly implemented, input validation is strict with type-safe argument parsing, and the code has no dangerous patterns like hardcoded credentials or arbitrary code execution. The server appropriately restricts functionality to user-owned domains via the backend API's verification mechanism. Minor code quality improvements around error handling could further enhance robustness. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

Eleion Scanner — MCP server

Drive the Eleion security scanner from an AI agent: register one of your own domains, prove ownership, queue a security scan (headers, TLS, DNS, ports, tech-fingerprint, plus AI-specific checks), and read the findings — severity, CVE, title, priority. Wraps the hosted Eleion Scanner API (https://scanner-api.eleion.io).

Tools

ToolWhat it does
scanner_register_target(target_url)Register one of your domains; returns the DNS TXT / well-known record to publish for ownership proof.
scanner_verify_target(target_id)Verify the ownership record you published.
scanner_start_scan(target_id, scan_profile?)Queue a scan (basic/full/deep) over a verified target.
scanner_get_scan_status(scan_id)Poll a scan's status and finding count.
scanner_get_findings(scan_id)List the findings (severity, CVE, template, title, priority).

Setup

{
  "mcpServers": {
    "eleion-scanner": {
      "command": "npx",
      "args": ["-y", "eleion-scanner-mcp"],
      "env": { "SCANNER_API_KEY": "your_tenant_key" }
    }
  }
}

Get a tenant key at https://scan.eleion.io. You can only scan domains you have registered and verified ownership of — this is not an arbitrary-target scanner.

The scan worker runs the analysis server-side; large scans take time, so poll scanner_get_scan_status until completed. Your registered domains and findings are processed by the hosted API. MIT licensed.
