BillionVerify 邮箱验证 MCP 服务器

BillionVerify MCP Server — TypeScript

Connect any AI assistant to BillionVerify email verification via the Model Context Protocol. Built with the official MCP TypeScript SDK.

Option 1 — Hosted Server (No Installation)

Use BillionVerify's hosted MCP server. There is nothing to install and no API key to paste: you sign in with your BillionVerify account over OAuth, and the connection is tied to that account.

The hosted server does not accept API keys (?api_key=, BV-API-KEY or Authorization: Bearer <api key> are all rejected). If you want to use an API key, use Option 2.

Detailed step-by-step guide: docs/connect-chatgpt-claude.md.
