Disposable email checker: disposable, role, free-mail and look-alike flags. List-based, no MX.

VerifiedStreamable HTTPWeb executableCommunication & CollaborationSecurity & Monitoring

Overview

AI-generated overview

A remote MCP service that checks an email address or domain for disposable, role, free-webmail and look-alike flags using a public list.

What you can do
Check a full email address for disposable domains, role addresses, free webmail providers, look-alike domains, syntax problems and one-character typo suggestions for big webmail domains. Check a bare domain for disposable, free webmail, look-alike and typo flags when the part before the @ is not needed. Read service metadata such as version, disposable-list version, domain and allowlist counts, last refresh time, upstream source, licence and current limits.
When to use it
Useful when validating sign-ups, cleaning a contact list, or screening an address before sending mail, and you want quick list-based signals without DNS or MX lookups.
Requirements
A remote streamable HTTP endpoint; no local runtime or package. No account is required, but an optional Authorization header with a bearer key raises rate limits.
Before you install
Checks are list-based only, with no MX or deliverability verification, so results are signals rather than proof. The email address or domain you submit is sent to the remote service. The optional Authorization key is a secret and should be supplied through the header, not shared.

Installation

In SourceWeft

  1. Open BurnerCheck in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/dev.workers.mike-tusa.burnercheck%2Fburnercheck/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

Other MCP clients

Add this to your client's mcpServers config.

check_email

Check an email address (disposable, role, free provider)

Check one email address against the disposable-email-domains list (CC0): disposable (domain or a parent domain is listed), role address (info@, admin@ …), free webmail provider, look-alike (confusable) domain, practical syntax, and a one-character typo suggestion for big webmail domains. List-based and offline: no MX/DNS lookup, so a valid format does not mean the mailbox exists. The address is sent in a POST body and not stored or logged. Read-only. Same engine, keys and limits as POST /v1/check.

Parametersemailrequired

check_domain

Check a domain (disposable, free provider, look-alike)

Check a domain only (no local part; anything containing "@" is refused): disposable (the domain or a parent domain is on the disposable-email-domains list), free webmail provider, look-alike (confusable) domain and a typo suggestion. Use this when you do not need the part before the @. Read-only. Same engine, keys and limits as GET /v1/domain/{domain}.

Parametersdomainrequired

get_meta

List version, size, source and limits

Return the service version and build, the disposable-list version, domain and allowlist counts, the last refresh time, the upstream source and licence (CC0), and the current limits. Does not count as a check. Read-only. Same data as GET /v1/meta.

Takes no parameters.

72% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
