WhyUser
Test a B2B landing page, ad or email before you launch it. A page test fields 50 simulated buyer agents and an ad or email test fields up to 300, up to 60 per role, scored as a chain of handoffs rather than an average. Get what is working, what is broken and what to fix in about 30 minutes from a URL. Every finding traces back to its source evidence.

Use the remote MCP URL on this page in your MCP client (Claude, Cursor, VS Code, and more). Copy the endpoint if your client needs a manual entry, then complete provider sign-in when your client connects — tools appear after authentication.
This endpoint requires provider sign-in, so MCPBundles could not list tools anonymously during the last probe. After you connect and authenticate in your MCP client, your session should receive the live tool list from the provider.
WhyUser may require signing in to the provider before tools can run. Connect through MCPBundles or your MCP client and complete any provider login when prompted.

This server appears in the MCPBundles directory. Verify you operate it to take over the listing — name, description, logo, contact email, and skill content. We email a 6-digit code to a maintainer address your server publishes in /.well-known/security.txt or /.well-known/mcpbundles.json. Free, takes about a minute.
MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms · Request removal
