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"
      }
    }
  }
}
