Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
create_inbox Create a disposable email inbox ~106
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.
| Name | Type | Req | Description |
|---|---|---|---|
| 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. |
No output schema declared.
No examples provided.
delete_inbox Delete an inbox ~49
Delete an inbox and everything in it. Inboxes expire on their own, so this is only needed when the user wants it gone immediately.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The inbox address to delete. |
No output schema declared.
No examples provided.
get_verification_code Extract the verification code from an email ~98
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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The inbox address. |
| message_id | string | yes | Message id from wait_for_email or list_messages. |
No output schema declared.
No examples provided.
list_domains List available email domains ~35
List the domains inboxes can be created on. Only needed when the user wants a specific domain; create_inbox picks one automatically.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
list_messages List messages in an inbox ~45
List the messages currently in an inbox, newest first. Use this to see what has already arrived, rather than waiting for something new.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The inbox address. |
No output schema declared.
No examples provided.
read_message Read the full contents of a message ~71
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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The inbox address. |
| message_id | string | yes | Message id from wait_for_email or list_messages. |
No output schema declared.
No examples provided.
wait_for_email Wait for an email to arrive ~100
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.
| Name | Type | Req | Description |
|---|---|---|---|
| address | string | yes | The inbox address to watch. |
| timeout | integer | – | Seconds to wait. Defaults to 30, maximum 55. |
No output schema declared.
No examples provided.
