Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

Remote (streamable-http)
Claude Code 
claude mcp add --transport http simpleverifier 'https://simpleverifier.com/api/mcp' --header 'Authorization: <Optional. Bearer followed by your SimpleVerifier API key (sv_live_...) from https://simpleverifier.com/api-keys. Leave empty to sign in with OAuth 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 <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

ToolWhat it does
verify_emailOne address: valid, risky or invalid, with a reason. Syntax, domain, disposable and live mailbox (SMTP) checks.
verify_emailsUp to 100 addresses in one call, deduplicated. Returns every result, or a job_id for get_job_results.
get_job_resultsProgress and per-address results of a verify_emails job, paged.
check_phone_formatFormat, E.164 form, country and numbering-plan line type. A format check only: it never says whether a number is in service.
check_domainA domain's MX, SPF and DMARC records, disposable status, and an optional catch-all probe.
get_usageYour 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/:

ClientFileGoes in
Cursorcursor.mcp.json~/.cursor/mcp.json or .cursor/mcp.json
VS Codevscode.mcp.json.vscode/mcp.json (asks for the key once, stores it securely)
Claude Desktopclaude_desktop_config.jsonSettings > Developer > Edit config (uses mcp-remote, needs Node.js)
Windsurf / Devin Desktopwindsurf.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"}}}'
