## What the machine actually did
The scanner recorded successful observations for 10 of 17 checks, but could not find an MCP manifest at the standard paths checked. It came up empty on 6 other checks too. 2 checks could not be measured; see the report limitations.

## What a visitor meets
1. **Entry observation** (observed). Primary entry is "Start Free Trial". 2 steps from the homepage. 3 fields, 0 marked required in the visible form. 1 sign in option: google. 2 of 3 visible entry-form inputs carry validation attributes; submission was not tested.
## Files generated from this scan
- **Prices in the HTML, not only after JavaScript** at `pricing page`, 1 hour, developer. Verify: The next scan reads the prices in the raw HTML of the pricing page, with none needing JavaScript to appear.
- **Agent checkout: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds a UCP manifest, a storefront MCP endpoint or another discovery file answering, and the checkout check passes.
- **Machine interfaces: where you stand** at `notes`, 10 minutes, no developer needed. Verify: The next scan finds the interface you published answering at its well-known path, and that check passes.
- **pricing.md** at `/pricing.md`, 20 minutes, no developer needed. Verify: The next scan fetches /pricing.md as text and records pricing as machine readable.
- **Organization structured data** at `homepage`, 15 minutes, developer. Verify: The next scan reads Organization and WebSite nodes in the homepage JSON-LD and the structured data check passes.
Each file is written from what this scan found on the site. The content is in the JSON once the evidence is opened: https://www.seconddoor.io/api/reports/mailchimp-6y58rs
## The agent door
- **machine_discoverability** 77/100. No restriction on the tested crawler names was found in robots.txt. On its first visit, our browser read the homepage. No user agent rule refused the tested retrieval crawler names.
- **programmatic_onboarding** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **pricing_legibility** 30/100. 3 prices appear only after JavaScript runs. A client that does not render pages sees no price at all.
- **agent_aware_instrumentation** 23/100. No MCP manifest was identified at the discovery paths checked. WooCommerce was detected; no checkout discovery interface was identified at the endpoints checked. Developer documentation describes an API, but only in prose.
- **machine_fetchable_trust** 85/100. Security.txt is published with a contact route. The homepage answers automated requests.
- **commercial_rails** 25/100. The pricing page includes a sales route and no prices were identified in its raw HTML. A self-serve signup entry was observed from the homepage.
## The human door
- **steps_to_first_value** 80/100. A signup form was reached in 2 steps from the homepage.
- **required_fields** not measured. Not measured: our scanner could not identify the required evidence on the pages checked.
- **verification_walls** not measured. Not measured: this read-only scan did not submit the form or perform the action needed to test this behavior.
- **error_recovery** not measured. Not measured: this read-only scan did not submit the form or perform the action needed to test this behavior.
