ScamCheck MCP Server

Scan suspicious messages, URLs, and text for scams inside any AI assistant that supports MCP (Claude Desktop, Claude Code, Cursor, and more). No signup or API key needed — works out of the box on the free anonymous tier.

Quick start (no API key)

Add to your Claude Desktop / Cursor config:

{
  "mcpServers": {
    "scamcheck": {
      "command": "npx",
      "args": ["scamcheck-mcp-server"]
    }
  }
}

That's it. Ask your assistant "is this message a scam?" and paste the message.

Higher limits (optional API key)

The anonymous tier is rate-limited per IP. For higher limits, grab a free key at scamcheck.tech/dashboard/developer and add it:

{
  "mcpServers": {
    "scamcheck": {
      "command": "npx",
      "args": ["scamcheck-mcp-server"],
      "env": {
        "SCAMCHECK_API_KEY": "sk-live-your-key-here"
      }
    }
  }
}

Tool: scan_message

Privacy Policy

Full policy: scamcheck.tech/privacy

  • What is collected: only the text or URL you ask the scan_message tool to check, plus the optional API key you configure. The extension reads nothing else from your computer or your conversations.
  • How it is used: the content is sent over HTTPS to the ScamCheck API (scamcheck.tech) and analysed to produce the verdict. Anonymous requests are rate-limited by IP address.
  • Storage and retention: scans may be stored to generate a shareable result link and to improve detection. Retention is described in the full policy linked above.
  • Third parties: ScamCheck uses an AI model provider to analyse scans. Your data is not sold or used for advertising.
  • Contact: privacy questions or deletion requests go to support via scamcheck.tech or the GitHub issues.
