Frequently asked questions

1

What is the `complete_signup_flow` tool?

It runs the full signup workflow in one call: creates an inbox, waits for the verification email, extracts the verification link and OTP, and returns them together.

2

What authentication is required?

A `UCT_API_KEY` environment variable is required for production workloads. Get your API key at [uncorreotemporal.com](https://uncorreotemporal.com).

3

What transport modes are supported?

The default transport is `stdio`. It also supports `streamable-http` and `sse` via the `UCT_MCP_TRANSPORT` environment variable.

4

How do inbox IDs work?

Each `inbox_id` is the same as the temporary email address (e.g., `agent42@uncorreotemporal.com`).

5

What are the timeout and polling defaults?

The default HTTP timeout is 20 seconds (`UCT_HTTP_TIMEOUT_SECONDS`). Polling intervals and timeouts for email waiting are configurable per tool call.
