Events and webhooks
Test inboxes tools for assistants (MCP)
The 1 tool an assistant can call for Test inboxes over MCP: what each one does, the scopes it needs, its arguments and an example call.
Addresses that keep what is posted to them for a day, to try webhooks without a server of your own. Create a test inbox, point an endpoint at its address, and read each request it received with its headers, its body and whether the signature matched. An assistant calls these tools over MCP; the same operations over HTTP are in the Test inboxes API. Tools for assistants lists every product, and MCP shows how to connect an assistant.
events_list_inboxes
List inboxes. The account's test inbox, when it has one that has not expired: an address that receives webhooks without a server of your own.
