Reviews ## What our customers say Questions ## MailboxValidator, answered ### ### Is there a MailboxValidator MCP server? APIANT's MCP server at https://mcp.apiant.ai works with MailboxValidator. Add that address to any AI client that takes a remote MCP server and sign in once in your browser. Your client can then run MailboxValidator actions on demand, or have APIANT build, test and run automations that use MailboxValidator. Nothing to install. ### ### What can your agent do in MailboxValidator? Any of MailboxValidator's 3 actions, including Check disposable email, Check free email and Validate Email. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can I use MailboxValidator directly from Claude, ChatGPT or Cursor? Yes. Connect your AI client to APIANT once and it works with MailboxValidator two ways. Ask it to do something in MailboxValidator once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running on its own. A one-off action uses your plan's tasks the same way an automation step does. ### ### Do I need to write code against the MailboxValidator API? No. APIANT connects to the MailboxValidator API for you, with your MailboxValidator API key. Describe what you want in plain language and your agent builds it on the MailboxValidator triggers and actions in the catalog. If you need an endpoint that is not there yet, your agent reads the MailboxValidator API documentation and adds it. ### ### Which apps can MailboxValidator connect to? Any app in the catalog; the list on this page pairs MailboxValidator with each of them. If the other app is missing, point your agent at its API documentation and it builds the connector. ### ### What happens when something fails? Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships. ### ### Is there a free plan? Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
