URL Safety Validator MCP checks a URL supplied by an AI assistant and returns a risk verdict with related details. It connects URL checks to Google Web Risk and Google Safe Browsing, with AI analysis, according to its homepage. An assistant can use the result as a pre-fetch signal when it encounters a link from an untrusted source. The verdict can inform whether the assistant should pause, flag the link for review, or continue; it is informational rather than an independent navigation control.
The service is centered on one URL-checking tool. It reports a verdict and supporting signals that can help an assistant assess a link before fetching it. The repository cautions that results are risk signals, not guarantees that a URL is safe or dangerous.
What can URL Safety Validator MCP do?
The check_url tool accepts a supplied URL and returns a classification alongside details about the check. The homepage says checks cross-check Google Web Risk and Google Safe Browsing with AI analysis. The output is intended to inform an agent's decision before it fetches or otherwise proceeds with an untrusted link.
- Return a SAFE, SUSPICIOUS, or DANGEROUS verdict.
- Provide an AI trust score and threat categories.
- Report SSL status and domain age.
- Flag whether a redirect chain was detected.
The repository describes a verdict as a risk signal, not a guarantee. The homepage positions the server as a pre-fetch gate, but does not claim it independently blocks navigation or forces the calling assistant to act on a result.
How URL Safety Validator MCP connects and authenticates
The homepage provides a hosted Streamable HTTP MCP endpoint, while the repository documents a local stdio mode. The repository lists integrations for Claude Code, Claude Desktop, LangChain, OpenAI Agents SDK, and LangGraph; the verified material does not confirm whether those integrations remain supported. The opened official page does not specify authentication requirements. It also does not precisely say what URL data is transmitted to third-party services, so those details should be confirmed with the vendor before relying on them.
Who is URL Safety Validator MCP best for?
This server may suit people building AI workflows that encounter links from untrusted sources and want a risk signal before fetching them. The homepage frames it as a pre-fetch check, including situations where an assistant processes URLs from sources it does not trust. The homepage lists a free plan with 10 calls per month and paid Pro and Enterprise plans. It does not specify whether an account or key is required for the free tier, or what usage and other entitlements the paid plans include; confirm those requirements with the vendor.
What URL Safety Validator MCP can access and change
The documented tool checks a URL supplied to it and returns verdict and risk details. The verified facts do not establish precisely what URL data is sent to Google Web Risk, Google Safe Browsing, or any other third party. They also do not document tools that change a website, account, or URL. A check itself is described as informational; consequential follow-up, such as fetching or blocking a link, is not enforced by this server according to the homepage. Its key limitation is that its verdict is not a guarantee and does not independently prevent navigation.
Alternatives to URL Safety Validator MCP
If the task is broader than assessing a supplied link, other directory listings may be worth comparing: DuckDuckGo MCP Server is a search-oriented option by its name, while Brave Search MCP is another search-named listing. For browser interaction rather than a stated URL risk verdict, compare Playwright MCP. These are alternatives to investigate, not equivalent safety checkers; their specific capabilities are not established by the facts verified for this listing.
