Validate user data instantly in Claude Desktop

The `validate_email` tool lets Claude Desktop check if a lead's inbox actually exists before you write an outreach sequence. Your agent runs SMTP checks and looks up MX records to filter out fake signups directly in your chat interface. You can also verify physical details with `validate_phone` and `validate_vat` to clean up your billing data. Claude Desktop handles the verification in the background, showing you the carrier type and company registration details immediately.

Run IP lookups using this MCP Server

This MCP Server exposes `geolocate_ip` so Claude Desktop can map incoming visitor IPs to exact coordinates, countries, and local service providers. Instead of opening a browser tab to trace an IP, you just paste the address into your chat. Pair that with `get_timezone` and `list_holidays` to let your agent schedule meetings or time-sensitive emails. You get exact local times and regional public holidays without looking up calendar rules manually.

Map domain data and take screenshots

The `enrich_company` tool extracts employee counts, industries, and LinkedIn profiles for Claude Desktop from a single domain name. Your agent builds complete target profiles while you chat about sales strategies. If you need visual confirmation, `website_screenshot` generates a permanent URL of any live site. Claude Desktop pulls the live render into your conversation so you can inspect layouts or verify active landing pages.
