URL Safety Validator MCP

URL Safety Validator MCP

Stop your agent from fetching a dangerous URL before it's too late.

Agents that process emails, scrape pages, or consume API responses encounter URLs from untrusted sources constantly. This server gives your agent a single call to gate every URL before it proceeds — returning a SAFE/SUSPICIOUS/DANGEROUS verdict backed by Google Web Risk, Google Safe Browsing, and AI analysis.

What It Does

One tool: check_url. One call returns:

• Verdict: SAFE / SUSPICIOUS / DANGEROUS
• AI trust score: 0–100 (0 = definitely dangerous, 100 = definitely safe)
• Threat categories: phishing, malware, unwanted_software, typosquatting, newly_registered, suspicious_redirect, brand_impersonation
• SSL status: valid or not
• Domain age: registration date and age in days
• Redirect chain flag: detected from URL parameters
• Database signals: raw results from Google Web Risk and Google Safe Browsing
• AI reasoning: 2–3 sentence plain-English explanation
• AI confidence: HIGH / MEDIUM / LOW

AI-powered analysis — NOT a simple database lookup.

When to Call This Tool

Call check_url BEFORE your agent:

• Fetches content from a URL found in an email
• Visits a link extracted from a scraped page or document
• Passes a URL to a browser tool or web scraper
• Stores or forwards a URL from any untrusted source
• Approves any outbound link in a content pipeline

If the verdict is DANGEROUS — halt. If SUSPICIOUS — flag for review. If SAFE — proceed.
