Before you install
- Basic checks: 1 of 1 passed
- Runs on your computer with your user’s permissions (files, network, apps).
- You fill in yourself:
VERIFUX_API_URL
You need
- npmNode.js installed (for the npx command)
Which app do you use?
Pick your app above. We remember it, so next time the button says “Install in …”.
Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json
{
"mcpServers": {
"snapshot": {
"command": "npx",
"args": [
"-y",
"@verifux/mcp"
],
"env": {
"VERIFUX_API_URL": "your-value"
}
}
}
}Run this in your terminal
claude mcp add snapshot --env VERIFUX_API_URL=your-value -- npx -y @verifux/mcpFill in the empty values before running it.
Or copy the settings yourself
Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json
{

}
}
}
}Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Common questions
Is Snapshot 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?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.0.4) reached the registry 5 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.
What can I use instead?

Verifux · MCP server
Let your coding agent check whether an AI agent can use a site
One tool, run_snapshot. Point it at any URL and it reports what an agent actually finds when it arrives: a band, a pass rate, the top findings, and whether the page declares an agent surface at all.
Zero dependencies. No sign-up. No API key.
Add it
Claude Code
claude mcp add verifux -- npx -y @verifux/mcpAny MCP client (Claude Desktop, Cursor, and others)
{"mcpServers": { "verifux": { "command": "npx", "args": ["-y", "@verifux/mcp"] } } }
Then just ask: *"run a Verifux snapshot on example.com"*.
What comes back
A real run, pasted verbatim:
Verifux snapshot for example.comBand: Mixed - 13 of 16 automated checks passed Findings: 0 critical, 2 major, 1 minor
Top findings: [MAJOR] No Organization or FAQPage structured data for AI answer engines [MAJOR] No H1 heading on the page [MINOR] No meta description for search engines or AI summaries to quote
AI agent surface: none detected
That last line is the one almost nobody checks. `none detected` means nothing an agent looks for was found: no declared tools, no /.well-known/mcp.json, no /agents.md.
We got exactly that on our own site. The file existed. We were serving it at the wrong path, and
nothing anywhere warned us. One path, and the whole surface was invisible.
Agent readiness is the only part of a site that can break without anyone noticing. No error, no alert, nothing in a dashboard. Just traffic that never arrives.
The tool
| Name | run_snapshot |
| Takes | url, any publicly reachable URL. Nothing else |
| Returns | Band (Strong / Mixed / Weak / Poor), pass rate over named automated checks, top findings, and whether an agent surface is declared |
| Env | VERIFUX_API_URL to point at a different backend. Defaults to https://api.verifux.app |
It deliberately has no score out of 100. That belongs to the full 54-checkpoint audit, and two different numbers out of 100 would contradict each other.
Prefer a terminal?
The same check as a CLI, with a CI mode that fails the build when the band drops:
npx @verifux/cli your-site.com --ci --min-band mixed→ [Verifux/verifux-cli](https://github.com/Verifux/verifux-cli)
This is the free snapshot: a fast, deterministic read. The full audit lives at [verifux.app](https://verifux.app).
This repo is the client shim. The audit engine behind api.verifux.app is not open source.
