Email Verify speaks the Model Context Protocol (MCP) with standard OAuth 2.0 sign-in, so Claude, ChatGPT, Grok, Muse, and any MCP client can verify email addresses with your account and credits. No separate integration to build.
The same details work in every client that supports remote MCP servers.
https://email-verify.simplebusinesssuite.com/mcpverify_email - 1 credit per callhttps://email-verify.simplebusinesssuite.com/.well-known/oauth-protected-resource/oauth/registerverifyEmail Verify is live in the Claude Connectors Directory; other directory listings are rolling out, and the custom-connector path works everywhere today.
Live in the Claude Connectors Directory - add it from the directory and sign in with OAuth.
Or add it manually: Settings, then Connectors, then Add custom connector. Paste the MCP endpoint
(https://email-verify.simplebusinesssuite.com/mcp) and Claude walks you through the OAuth sign-in with your Email Verify account.
Settings, then Apps and connectors, then add a custom MCP server with the
MCP endpoint and OAuth. Sign in once and ChatGPT can call verify_email in chat.
Connectors, then New Connector, then Custom. Paste the MCP endpoint. If your Grok client does not offer OAuth, create an API key in your dashboard and use it as a Bearer token.
Ask Muse to add a custom connector for Email Verify and give it the MCP endpoint plus this page. Muse can store your API key in its Secure Credentials Store, or use OAuth.
Every plan includes API keys, and they work with the same MCP endpoint.
Sign in, open API keys, and create a key. Then configure your client with
header Authorization: Bearer evk_YOUR_KEY pointed at https://email-verify.simplebusinesssuite.com/mcp.
Keys draw from the same credit balance as your dashboard. Full REST details live in the API docs,
and agents can read llms.txt for a machine-readable brief.
