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 <API key>
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":"[email protected]"}}}'
