Tool Coverage80
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 30% of tool parameters carry a description.Partial
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

check_for_callbacks ~85
See if SSRF, XSS, or canary callbacks arrived in the last N minutes. Use after generate_ssrf_payload / generate_xss_callback / generate_canary_token. For a website verification email, use wait_for_email.
| Name | Type | Req | Description |
|---|---|---|---|
| identifier | – | – | – |
| since_minutes | integer | – | – |
| webhook_token | string | yes | Webhook UUID returned by create_webhook |
Structured output declared, but exposes no named fields.
No examples provided.
create_webhook ~105
Create a disposable inbox to sign up on a website: HTTP URL, temp email, DNS. Use this first when the user wants to sign up, receive a verification / magic-link / password-reset email, catch a webhook callback, or get a one-off URL. Returns token, url, email ({token}@email.webhook.site), and dns. Next: give the email or URL to the site, then wait_for_email, then follow_email_link or use the OTP.
Input schema present but exposes no named parameters.
Structured output declared, but exposes no named fields.
No examples provided.
create_webhook_with_config ~110
Create a webhook that returns a custom status, body, timeout, CORS, or alias. Use when the user wants the endpoint to pretend to be an API (404, delay, JSON body) instead of a default 200. For a normal sign-up inbox, use create_webhook.
