Scans web apps for security, SEO, and AI-visibility issues via MCP, with free scans and focused checks.

Scanned 8 days ago Due for re-check
A server can change after it's graded. Re-run the automated scan to refresh this report.
This grade is deterministic and reproducible: the same server surface always yields the same grade under a given algorithm version. It is a real automated assessment computed by the MCPGrade engine from what the probe actually observed — not a fabricated or opinion score. It is not a manual human pentest, so it can miss context-specific risks.
Every signal below was measured directly by the automated probe. The grade is derived only from evidence like this — nothing is assumed.
The simplyscan MCP server exposes 7 tools, focused primarily on filesystem, web, and communication capabilities. Its published description reads: "Scans web apps for security, SEO, and AI-visibility issues via MCP, with free scans and focused checks". It communicates over Streamable HTTP using the 2025-06-18 protocol revision, and does not require authorization to connect. MCPGrade currently rates simplyscan F — a critical issue was found and the server should not be connected as-is. Its most notable findings include "Data-exfiltration parameters" and "Data-exfiltration parameters". This report is a deterministic, reproducible automated assessment: the same observed surface always yields the same grade under a given algorithm version, and it is refreshed as new scans arrive and free to read — but it is not a substitute for a manual human security review. Always re-check simplyscan's advertised tools, transport security, and authorization posture before connecting an autonomous agent or sharing sensitive context with it.
Add simplyscan to an MCP client using the endpoint below. Review the grade and findings above before granting an autonomous agent access.

Run a free SimplyScan security & speed scan of a deployed web app URL. Returns a 0-100 score and findings (exposed secrets, missing Supabase RLS, frontend leaks, speed issues). Best for apps built wit
Grade a URL's HTTP security headers (CSP, HSTS, X-Frame-Options, Referrer-Policy, Permissions-Policy, COOP, COEP) A-F.
AEO check: whether AI answer engines (ChatGPT/GPTBot, Claude, Perplexity, Google-Extended, etc.) can crawl and cite the site, plus llms.txt and structured-data signals.
Sorted worst-first. Each finding shows its severity, what it means, its OWASP MCP Top-10 mapping, and a recommended fix — the check id links to the exact methodology row that produced it.
