## MCP tools (7)

### `create_inbox` (~106 tokens)

Create a disposable email inbox

Create a temporary email address that can receive mail. Use this when the user needs an email address for a signup, a trial, or anything they do not want to give a real address to. Returns the address and when it expires.

Input parameters:

- `domain` (string): Optional domain from list_domains. Random if omitted.
- `username` (string): Optional local part, for example 'my-test'. Lowercase letters, digits, dot, underscore and hyphen only. Random if omitted.

### `wait_for_email` (~100 tokens)

Wait for an email to arrive

Wait for the next email to arrive at an inbox, up to 55 seconds. Use this straight after triggering a signup or password reset. Returns the message summary, or reports that nothing arrived. Nothing arriving is not an error: the mail may simply be slow, and calling this again continues waiting.

Input parameters:

- `address` (string, required): The inbox address to watch.
- `timeout` (integer): Seconds to wait. Defaults to 30, maximum 55.

### `get_verification_code` (~98 tokens)

Extract the verification code from an email

Pull the verification or one-time code out of a message. Use this after wait_for_email when the user needs a code to complete a signup or login. Requires a paid API key. If no code is found with confidence, that is reported rather than guessed, because a wrong code is worse than none.

Input parameters:

- `address` (string, required): The inbox address.
- `message_id` (string, required): Message id from wait_for_email or list_messages.

### `list_messages` (~45 tokens)

List messages in an inbox

List the messages currently in an inbox, newest first. Use this to see what has already arrived, rather than waiting for something new.

Input parameters:

- `address` (string, required): The inbox address.

### `read_message` (~71 tokens)

Read the full contents of a message

Read a message's full body and attachment list. Use this when the user wants to see what an email actually says, or when get_verification_code could not find a code.

Input parameters:

- `address` (string, required): The inbox address.
- `message_id` (string, required): Message id from wait_for_email or list_messages.

### `list_domains` (~35 tokens)

List available email domains

List the domains inboxes can be created on. Only needed when the user wants a specific domain; create_inbox picks one automatically.

### `delete_inbox` (~49 tokens)

Delete an inbox

Delete an inbox and everything in it. Inboxes expire on their own, so this is only needed when the user wants it gone immediately.

Input parameters:

- `address` (string, required): The inbox address to delete.
