Common questions

Is BillionVerify safe?

It passed 4 of 5 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: BILLIONVERIFY_API_KEY

Does it run on my computer or in the cloud?

Either way works: install it on your computer or connect to the cloud version.

Is it still maintained?

The GitHub repo last changed 29 days ago, and the latest version (1.1.1) reached the registry 29 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

In the same category: Inbox Zero, Agent-Native Chat, draw.io

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.


Server URL	`https://mcp.billionverify.com/mcp`
Transport	Streamable HTTP
Authentication	OAuth 2.1 (sign in with your BillionVerify account)

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

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

ChatGPT (web)

Settings → Apps & Connectors → Advanced settings → turn on Developer mode.
Settings → Apps & Connectors → Create.
Name BillionVerify, MCP server URL https://mcp.billionverify.com/mcp, authentication OAuth → create.
Sign in to BillionVerify in the window that opens and approve access.
In a new chat, click + → Developer mode → enable BillionVerify.

Claude (claude.ai / Claude Desktop)

Customize → Connectors → + → Add custom connector.
Name BillionVerify, URL https://mcp.billionverify.com/mcp → Add (leave Advanced settings empty).
Click Connect, sign in to BillionVerify and approve access.
In a chat, click + → Connectors and make sure BillionVerify is on.

Team / Enterprise: an Owner adds the connector under Organization settings → Connectors, then each member clicks Connect.

Claude Code

claude mcp add --transport http billionverify https://mcp.billionverify.com/mcp

Then run /mcp inside Claude Code, select billionverify and finish the sign-in in your browser.

Cursor

Add to ~/.cursor/mcp.json (global) or .cursor/mcp.json (project), then click Connect next to the server in Settings → MCP:

"mcpServers": { "billionverify": { "url": "https://mcp.billionverify.com/mcp" } } }

Option 2 — Self-Hosted (TypeScript / Node.js)

Run your own MCP server using this TypeScript implementation.
