Email verification inside Claude, ChatGPT and Cursor
The VeriMailX Model Context Protocol server lets any MCP-compatible AI assistant verify email addresses, clean lists and check your credits — acting as you, secured by OAuth.
Server URL
https://www.verimailx.com/mcpTools exposed
verify_email
Full SMTP-level verification of a single address, returning status, risk signals and provider details. Uses 1 credit.
verify_email_list
Verify up to 20 addresses in one call. Stops early and tells the assistant if credits run out.
check_disposable_domain
Free lookup against our 8,200+ domain disposable blocklist. No credits consumed.
get_credit_balance
Returns the signed-in account's plan, remaining credits and monthly usage.
list_validation_jobs
Recent bulk verification jobs with counts so the assistant can summarise past runs.
How to connect
- Create a VeriMailX account (1,000 free validations included) — the MCP server acts on that account.
- In your assistant, add a custom connector / remote MCP server and paste the URL above.
- Sign in when the OAuth consent screen appears and approve access. No API key needed.
- Ask your assistant to verify an address — it will call the tools automatically.

Secure by default
Every request is authenticated with OAuth 2.1 — the assistant never sees your password or API key, and tools only ever touch your own data. Revoke access any time from your dashboard.
