## MCP tools (3)

### `generate_inbox` (~91 tokens)

Generate a disposable email inbox for testing signups, OTP verification, magic links, and password resets. Instant and local — no network request. Use the returned address wherever an email is required, then call wait_for_email to read what arrives. Free tier: 30-minute retention, no signup needed.

Input parameters:

- `prefix` (string): Optional prefix for the inbox name, e.g. your app or test name

### `wait_for_email` (~171 tokens)

Wait for an email to arrive in a ZeroDrop inbox and return it with the OTP and magic link already extracted — no parsing needed. Blocks until an email matching the filters arrives or the timeout is reached. Use after triggering a signup, login, or password-reset flow.

Input parameters:

- `require_otp` (boolean): Only match emails with an extracted OTP code
- `subject_contains` (string): Only match emails whose subject contains this text
- `timeout_seconds` (number): How long to wait before giving up (default 30, max 120)

### `check_inbox` (~62 tokens)

Check a ZeroDrop inbox right now without waiting. Returns the most recent emails with OTPs and magic links already extracted, or an empty list if nothing has arrived yet.

Input parameters:

- `inbox` (string, required): The inbox address (or name) returned by generate_inbox
