First indexed and scored.

## MCP tools (8)

### `create_mailbox` (~119 tokens)

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 never expires;
call delete_mailbox when it is no longer needed. Then use wait_for_message to get the mail it receives.

Input parameters:

- `domain`: One of the account's own verified domains (see list_domains). Leave empty for a random shared domain.
- `name`: Local part before the @. Only allowed on the account's own domains. Leave empty for a random name.

Output parameters:

- `created_at`
- `domain` (string)
- `email` (string)
- `message_count`
- `own_domain` (boolean)

### `wait_for_message` (~305 tokens)

Wait for an email (OTP, verification link)

Return the newest UNREAD message matching the filters, or wait until one arrives.

The result includes `otp` (the one-time code found in the message, or null), `codes`, `links` 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).

Input parameters:

- `body_format` (string): Which body to return: "text" (plain text, default), "html" (the raw HTML exactly as received; falls back to text when the message has no HTML part) or "both".
- `email` (string, required): The email address, as returned by create_mailbox or list_mailboxes.
- `from_contains`: Only messages whose sender name or address contains this text.
- `max_chars` (integer): Maximum characters of message text to return (longer text is cut).
- `max_html_chars` (integer): Maximum characters of HTML to return when body_format is html or both (longer HTML is cut).
- `subject_contains`: Only messages whose subject contains this text.
- `timeout_seconds` (integer): How long to wait for a new message (hosted server mcp.tmailor.com: at most 60).

Output parameters:

- `email` (string)
- `hint` (string)
- `message`
- `message_id` (string)
- `status` (string)
- `waited_seconds` (integer)

### `list_messages` (~104 tokens)

List messages of an address

List the messages an address received in the last 24 hours, newest first (no body; use read_message).

Input parameters:

- `email` (string, required): The email address, as returned by create_mailbox or list_mailboxes.
- `from_contains`: Only messages whose sender contains this text.
- `limit` (integer): Maximum number of messages to return.
- `subject_contains`: Only messages whose subject contains this text.
- `unread_only` (boolean): Only messages not read yet.

Output parameters:

- `email` (string)
- `messages` (array)
- `total` (integer)
- `untrusted_content_notice` (string)

### `read_message` (~209 tokens)

Read one message

Read one message: `otp`, `codes`, `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.

Input parameters:

- `body_format` (string): Which body to return: "text" (plain text, default), "html" (the raw HTML exactly as received; falls back to text when the message has no HTML part) or "both".
- `email` (string, required): The email address, as returned by create_mailbox or list_mailboxes.
- `max_chars` (integer): Maximum characters of message text to return (longer text is cut).
- `max_html_chars` (integer): Maximum characters of HTML to return when body_format is html or both (longer HTML is cut).
- `message_id` (string, required): The message id from list_messages.

Output parameters:

- `email` (string)
- `message`

### `delete_mailbox` (~71 tokens)

Delete an address

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.

Input parameters:

- `email` (string, required): The email address, as returned by create_mailbox or list_mailboxes.

Output parameters:

- `deleted` (boolean)
- `email` (string)

### `list_mailboxes` (~36 tokens)

List addresses

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

Input parameters:

- `limit` (integer): Maximum number of addresses to return.

Output parameters:

- `mailboxes` (array)
- `more` (boolean)

### `list_domains` (~30 tokens)

List usable domains

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

Output parameters:

- `own_domains` (array)
- `shared_domains_available` (boolean)

### `account_status` (~28 tokens)

Account status and quota

Show the remaining mailbox quota, the active plans and the request rate of the Tmailor account.

Output parameters:

- `addresses` (integer)
- `client_ip` (string)
- `daily_request_cap`
- `ip_allowlist_enforced`
- `manage_url` (string)
- `plans` (array)
- `quota_remaining` (integer)
- `quota_total` (integer)
- `quota_used` (integer)
- `requests_per_minute` (integer)
