Verify emails with ChatGPT before your AI SDR sends
ChatGPT supports remote MCP connectors, so there's nothing to install. Add RocketVerifier's hosted MCP endpoint with your API key, and ChatGPT can call every verification tool — from any device, including mobile.
Example, inside ChatGPT:
ChatGPT calls RocketVerifier's verification API for you and hands back a clean, classified result — no dashboard upload, no manual CSV round-trip.
Connect ChatGPT in 3 Steps
Takes about two minutes. 100 free credits included so you can try it before you pay for anything.
Get an API key
Sign up free and grab a key from the RocketVerifier dashboard — claim 100 free trial credits with a quick card check.
Add the remote connector
In ChatGPT’s connector settings, add the hosted MCP URL and your API key as the bearer token.
Ask ChatGPT to verify
Reference an email or list in the chat and ask ChatGPT to verify or clean it before you send.
Add as a remote MCP connector in ChatGPT settings:
URL: https://api.rocketverifier.com/mcp Auth: Bearer rv_live_your_api_key
Full setup guides are in the MCP documentation and API reference.
Confidence scores, not guesses
Every result comes back with a 0–100 score and evidence — SMTP response, provider detection, DNS records — so ChatGPT can make the send/skip call.
Idempotent by default
Every write request auto-generates an Idempotency-Key, so a retried or automated call can never double-charge credits or create duplicate jobs.
Never pay for a non-answer
Unknowns and duplicates are always free — unlike incumbents that charge for "risky" or "unknown" results your workflow can't act on.
Common Questions About ChatGPT + RocketVerifier
Do I need to install anything for ChatGPT?
No. The hosted endpoint runs entirely on RocketVerifier’s servers — you only need a URL and your API key, no local process to manage.
Is the hosted endpoint the same as the npm MCP server?
Yes, it exposes the exact same 10 tools. The hosted version is best for clients like ChatGPT that support remote connectors instead of local stdio servers.
Does using MCP tools cost credits?
Free tools (check_disposable, mx_lookup, check_domain_auth) never cost credits. Verification tools use the same credits as the API and dashboard.
