What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

verify_email
Full check of one address: RFC syntax and normalisation, domain existence and MX records (incl. null-MX and implicit-MX), disposable-provider list (10k+ domains), role account, free-mail provider, typo suggestion; optional SMTP RCPT probe with catch-all detection and optional SPF

Same checks as verify_email for a list, run in parallel with per-domain DNS caching; returns per-address results, a summary by status, and `clean` (the deliverable ones). Charged per unique address. Example: emails ['a@x.com','b@y.org'], smtp_check false. Response: result with st
domain_check
Does the domain accept mail, which MX hosts, is it a disposable or free-mail provider, does it publish SPF and DMARC (and the DMARC policy)? Use before trusting a sender domain or when onboarding a company. Example: domain 'noahsarch.tech'. Response: result with status (deliverab
extract_emails
Find every address in a block of text or HTML (deduped by default). Free. Pair with verify_emails. Response: result with status (deliverable | risky | undeliverable | invalid | unknown), reason, score 0–100, the checks run, plus data_confidence, estimated_items[], sources[], data
suggest_fix
Fix common typos: gmial.com, hotmail.con, yaho.com, stray spaces/dots. Returns the suggestion (or null) and which fixes applied. Free. Example: email 'sara@gmial.con'. Response: result with status (deliverable | risky | undeliverable | invalid | unknown), reason, score 0–100, the

Common questions

Is Email Verifier safe?

It passed 2 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: X-API-Key

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 (0.1.1) reached the registry 10 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 Business and above.

What can I use instead?

In the same category: Inbox Zero, Agent-Native Chat, draw.io
