GrabMail disposable email is a remote MCP server that gives an AI agent 6 tools, among them create_inbox, delete_message, list_domains. It answers at https://grabmail.io/mcp over streamable HTTP, and it listed its tools to an anonymous client, so no sign-in was needed for that. Our probes reached it 4 of 4 times since 23 September 2026; the last check, on 7 November 2026, succeeded.
Disposable email for agents: create an inbox, wait for the message, read the code. No key needed.
Description as the publisher wrote it.
| Tool | What it does |
|---|---|
create_inbox | Invent a fresh, unused disposable email address you can give out immediately. Nothing is created or reserved server-side — an address exists as soon as mail arrives at it — so this never fails and needs no account. Public domains: grabmail. Inputs: domain, prefix |
delete_message | Remove a message now rather than waiting for it to expire. Idempotent. Inputs: address, id |
list_domains | The public domains anyone may use. A domain of your own needs no account or key either — just an MX record pointing here. These public domains are on disposable-mail blocklists; if a form rejects them, see the premium pool noted in the resu |
list_messages | Everything waiting at an address, newest first. Returns immediately, including when the mailbox is empty — use wait_for_message if you are expecting something that has not arrived yet. Inputs: address, limit, before |
read_message | The full message: sender, subject, plain text, HTML and any attachments. This is where a confirmation code or a sign-in link will be. Read `text`: when the sender shipped HTML only, as most transactional mail does, it holds a plain-text ren Inputs: address, id |
wait_for_message | Blocks until a new message arrives at the address, then returns it in full — the tool to use after submitting a sign-up form. Waits at most 25 seconds and then returns with timed_out set to true; call it again to keep waiting. Optionally wa Inputs: address, timeout_seconds, from_contains, subject_contains, since_id |

Yes. It is published by grabmail.io and served from grabmail.io, the vendor's own domain: https://grabmail.io/mcp.

Put the server under mcpServers in ~/.cursor/mcp.json with the URL https://grabmail.io/mcp. The exact JSON is above, with the same setup for Claude Code, Claude Desktop, VS Code, Windsurf, Zed, Gemini CLI and the rest.
It listed its tools to an anonymous client, so reading the tool list needs no key. Individual tools can still ask for credentials in their own inputs.

First indexed 22 September 2026. The tools are exactly what the server returned; nothing on this page
is inferred from its name. Ranking in Neuronto search is never for sale.
