How to Use the AbstractAPI MCP in Windsurf

Q: Can Windsurf use AbstractAPI to check if an email address is real?

Yes. Just ask Windsurf to check an email. It will use the validateemail tool from the AbstractAPI server to run deliverability checks, including an SMTP verification, to confirm the inbox actually exists.

Let Windsurf's Cascade agent use AbstractAPI to enrich data, validate contacts, and geolocate users automatically.

Perplexity

Validate Customer Data Instantly

This MCP Server gives Windsurf's Cascade agent a direct line to data validation tools. When you get a new lead, Cascade can grab their email and phone number, then run them through `validate_email` and `validate_phone` automatically. For B2B customers, it can even use `validate_vat` to check their tax ID. The result is a clean contact record without you doing any of the work. Imagine you only have a customer's domain. Cascade can use `enrich_company` to find their industry and employee count, then `website_screenshot` to grab a shot of their homepage for your dashboard. This all happens in the background while you focus on your code.

Build Location-Aware Features in Windsurf

Give your agent the tools to work with location data. When you're building an international app, Cascade can use `geolocate_ip` to identify a user's country and currency from their IP address. You don't have to hard-code country lists anymore. It can also pull timezone information with `get_timezone` or find a country's public holidays using `list_holidays`. Cascade chains these actions, so a single prompt like "set up my new user from this IP" gets you a complete, localized profile in seconds.

Personalize UI with Simple Avatars

Your agent can now generate simple, clean avatars on the fly. Give Cascade a name and the `generate_avatar` tool returns a URL for an initials-based image. It's perfect for placeholder UIs or internal tools where you just need something that looks right. You're not just getting an image. Cascade can combine this with other tools. For example, it could find a user's company name with `enrich_company`, then use their initials for an avatar, all as part of one automated workflow inside Windsurf.
