Transport: Streamable HTTP
Category: Chat & email
You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http simpleverifier https://simpleverifier.com/api/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "simpleverifier": {
      "url": "https://simpleverifier.com/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "simpleverifier": {
      "type": "http",
      "url": "https://simpleverifier.com/api/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Optional. Bearer followed by your SimpleVerifier API key (sv_live_...) from https://simpleverifier.com/api-keys. Leave empty to sign in with OAuth instead. API and MCP access come with the Pro, Busin…

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

The server asks you to sign in before it lists its tools.

Common questions

Is SimpleVerifier safe?

It passed 3 of 3 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: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 13 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 in developer mode.

What can I use instead?

SimpleVerifier MCP server

A remote Model Context Protocol server that gives ChatGPT, Claude, Cursor, VS Code and other MCP clients email and phone checks as tools.

Endpoint: https://simpleverifier.com/api/mcp (Streamable HTTP)
Auth: OAuth sign-in (ChatGPT, claude.ai, Claude Code) or Authorization: Bearer
Plan: MCP and API access need a SimpleVerifier Pro, Business or Agency plan. Tool calls count against the plan's monthly API calls. Pricing
Docs: https://simpleverifier.com/docs/mcp

This repo holds the registry manifest (server.json) and ready-to-copy client configs. The server itself is hosted; there is nothing to install or run.

Tools

Tool	What it does
`verify_email`	One address: `valid`, `risky` or `invalid`, with a reason. Syntax, domain, disposable and live mailbox (SMTP) checks.
`verify_emails`	Up to 100 addresses in one call, deduplicated. Returns every result, or a `job_id` for `get_job_results`.
`get_job_results`	Progress and per-address results of a `verify_emails` job, paged.
`check_phone_format`	Format, E.164 form, country and numbering-plan line type. A format check only: it never says whether a number is in service.
`check_domain`	A domain's MX, SPF and DMARC records, disposable status, and an optional catch-all probe.
`get_usage`	Your plan, what it includes, this month's usage and the rate limit.

Only valid means the mail server confirmed the mailbox. Anything unconfirmed (catch-all domains, providers that hide mailbox status, servers that don't answer) comes back risky.

Connect

Claude Code

claude mcp add --transport http simpleverifier https://simpleverifier.com/api/mcp

then run /mcp inside a session to sign in, or pass a key:

claude mcp add --transport http simpleverifier https://simpleverifier.com/api/mcp --header "Authorization: Bearer YOUR_API_KEY"

ChatGPT and claude.ai: add a custom connector with the URL https://simpleverifier.com/api/mcp, choose OAuth, then sign in on the SimpleVerifier screen. Step-by-step: https://simpleverifier.com/docs/mcp

Cursor, VS Code, Claude Desktop, Windsurf: copy the matching file from configs/:

Client	File	Goes in
Cursor	`cursor.mcp.json`	`~/.cursor/mcp.json` or `.cursor/mcp.json`
VS Code	`vscode.mcp.json`	`.vscode/mcp.json` (asks for the key once, stores it securely)
Claude Desktop	`claude_desktop_config.json`	Settings > Developer > Edit config (uses `mcp-remote`, needs Node.js)
Windsurf / Devin Desktop	`windsurf.mcp_config.json`	`~/.config/devin/mcp_config.json` (older builds: `~/.codeium/windsurf/mcp_config.json`)

Create an API key at https://simpleverifier.com/api-keys. Keys start with sv_live_. Keep them out of shared config files and repositories.

Try it with curl

curl https://simpleverifier.com/api/mcp \

-H "Authorization: Bearer $SIMPLEVERIFIER_KEY" \ -H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"verify_email","arguments":{"email":"jane@company.com"}}}'
