What it can do

Tool names and descriptions exactly as the server reported them on Nov 10, 2026. The maker wrote them, not us; we show them as plain text.

get_service_info
Read the Machine Inbox service instructions: pricing, payment rails, endpoints, and limits.
create_inbox
Request a new paid inbox. Buying requires an out-of-band payment (Stripe MPP or x402 USDC on Base); this tool returns the live HTTP 402 payment challenge plus exact instructions to complete the purchase. Standard inbox: $2.00.
get_inbox
Read an inbox: address, status, expiry, limits, and usage.
list_messages
List messages in an inbox, newest first. Pass after= to poll for only new mail.
get_message
Fetch one message with parsed text, HTML, and attachment download URLs.
get_verification_code
Extract the newest one-time verification code or confirmation link from inbound mail. Ideal for signup and login flows.
reply_to_message
Send an included plain-text reply to the authenticated sender of an inbound message.
set_webhook
Register or replace the inbox webhook: an HMAC-signed POST fires on every inbound message with metadata, extracted verification codes, and injection risk (never the body). Returns the signing secret.
get_webhook
Read the inbox webhook state: URL, delivery counters, and whether it is disabled. The secret is only returned by set_webhook.
delete_webhook
Remove the inbox webhook.
delete_inbox
Delete an inbox: revokes the token and erases stored mail.

Common questions

Is Machine Inbox safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).

What can I use instead?
