Common questions

Is URL Safety Validator MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: ANTHROPIC_API_KEY, GOOGLE_WEB_RISK_API_KEY, GOOGLE_SAFE_BROWSING_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.27) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

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.
