1Add it to your app

In Claude on the web or desktop, open Settings → Connectors and choose Add custom connector.
Name it verified.fyi and paste https://verified.fyi/mcp as the URL. Leave the OAuth fields empty.
In a chat, check verified.fyi is switched on in the tools menu, then ask about any site.

Run this in your terminal. Add --scope user after add to use it in every project.

TERMINAL

claude mcp add --transport http verified-fyi https://verified.fyi/mcp

Open Settings → Apps → Advanced settings and turn on Developer mode. It's available on paid plans.
Back in Apps, choose Create. Name it verified.fyi, paste https://verified.fyi/mcp as the server URL and set authentication to No authentication.
In a chat, add verified.fyi from the + menu, then ask about any site.

Add to Cursor

Or add this to ~/.cursor/mcp.json, or .cursor/mcp.json in a project.

MCP.JSON

{
  "mcpServers": {
    "verified-fyi": {
      "url": "https://verified.fyi/mcp"
    }
  }
}

Install in VS Code

Or add this to .vscode/mcp.json, then use it from Copilot Chat in agent mode.

MCP.JSON

{
  "servers": {
    "verified-fyi": {
      "type": "http",
      "url": "https://verified.fyi/mcp"
    }
  }
}

Run this in your terminal.

TERMINAL

gemini mcp add --transport http verified-fyi https://verified.fyi/mcp

Any app that connects to remote MCP servers over Streamable HTTP only needs the URL. There's no authentication. Apps that can only run local servers can reach it through mcp-remote:

MCP CONFIG

{
  "mcpServers": {
    "verified-fyi": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://verified.fyi/mcp"]
    }
  }
}

2Ask about a site

“Is this shop legit? I'm about to pay.”

“Check the hotel's booking site before you enter my card details.”

“Is the domain this email came from a scam?”

“Find this cheaper somewhere else, and check each shop on verified.fyi first.”

Tools and endpoints

Two tools, both read-only. They return structured JSON as well as text.

check_website

The trust report for a domain or any URL on it: verdict, 0–100 score, a plain-English summary and up to five red flags, worst first. Sites we've already checked come back instantly. A new site is scanned on the spot, which usually takes under a minute. If it isn't ready after about 25 seconds, the agent is told to call again shortly.

verdictscoresummaryred_flagschecked_atreport_url

list_research

Our published research on scam and phishing sites. Each story comes with its headline number, a short description, a link and its JSON dataset, for when you want figures to cite.

titleheadline_staturldata_url

JSON API

Building your own agent? GET /api/review/{domain} returns the full report, including every signal and the score for each category. No key, and CORS is open.

llms.txt

/llms.txt explains the site, the API and the MCP server to language models. /llms-full.txt adds the full scoring method and response fields.

Good to know

Before you connect

Fair limits

Lookups of sites we've already checked are never rate limited. Brand-new scans share the website's limits, so an agent checking hundreds of unknown sites at once will be asked to wait.

Reports are public

When your agent checks a site for the first time, its report is published here, just like a check from the homepage. Only the site is published, never who asked. See our privacy policy.

Credit and a link

Every result links to the full report. If your app shows our data, please name verified.fyi and keep that link.

A score is a guide

It sums up the risk signals our checks found, and it can be wrong. Nobody can pay for a better score. Your agent gets the same verdict anyone sees on the site, with a link to the evidence behind it.

Rather check a site yourself?

Paste any address on the homepage. You'll get the same report your agent reads.
