Receive-only temporary email addresses for AI agents: create an inbox, wait for an email, read it.
Tmailor gives an assistant real, receive-only temporary email addresses: create an inbox, wait for a message, read it and follow its links.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
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/io.github.tmailor-com%2Ftmailor-mcp/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.Add this to your client's mcpServers config. The client completes OAuth sign-in on first connect.

}MCP server for the Tmailor Open API. It gives AI agents (Claude, Cursor, VS Code Copilot and any other MCP client) real, receive-only temporary email addresses: sign up somewhere, wait for the email, read it and follow its link.
Billing counts mailboxes, not requests: creating an address uses 1 unit of quota, while waiting for and reading mail is free. Addresses never expire.
With a paid plan you can skip this package and connect to the hosted server https://mcp.tmailor.com/mcp
(Streamable HTTP, sign-in with OAuth). In Claude it is listed in the Connectors Directory as Tmailor Temp Mail;
other clients that support remote MCP servers take the URL directly. Setup for each client:
https://platform.tmailor.com/docs (section "Use with AI agents (MCP)").
The local server below works on every plan, including Free.

tmailor-mcp is listed in the MCP Registry as

body_format on wait_for_message and read_message: text (plain text, default, cut to max_chars), html

message has an HTML part; html on a message without one returns the text instead.

Tools take and return email addresses only. The address tokens of the API stay inside the server process, so they never end up in the conversation.

not committed to a repository. Revoke a leaked key at https://platform.tmailor.com/keys.wait_for_message never returns the same message twice within one server process. Two MCP servers waiting on the
same address at the same time (for example two agents sharing one key) can both receive the same message.tmailor-sdkMIT

Create a temporary email address
Create a new temporary email address that can receive mail right away. Uses 1 unit of the account's mailbox quota (checking and reading mail is free). The address is receive-only and never expires; wait_for_message returns the mail it receives and delete_mailbox removes it.
namedomainWait for an email
Return the newest UNREAD message matching the filters, or wait until one arrives. The result includes the sender, the subject, the `links` found in the message and the body chosen by `body_format` (plain text by default; "html" or "both" for the raw HTML). Returning a message marks it as read, so the next call waits for the next one. If nothing arrives in time, `status` is "timeout": call again if the email may still come (for example the sign-up was just submitted).

Read one message: sender, subject, `links` and the body. Marks the message as read. `body_format` picks the body: "text" (plain text, default), "html" (the raw HTML exactly as received) or "both". `has_html` says whether the message has an HTML part.

Delete an address for good (like Delete on tmailor.com): it stops receiving and cannot be restored. Used quota is not returned. Only call this when the user's task no longer needs the address.

List the account's addresses, newest first, with their message counts.

List the account's own domains (custom names are allowed on verified ones) and whether shared domains are available.

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.
