## What the machine actually did
The scanner recorded successful observations for 9 of 14 checks, but could not find an MCP manifest at the standard paths checked. It came up empty on 4 other checks too. 1 check could not be measured; see the report limitations.
- ok      reach the site at all
- ok      find out whether machines are welcome
- ok      ask whether the door opens for requests carrying the AI crawlers' names
- ok      read the site's own guide for language models
- ok      find out what pages exist
- ok      find a contact route for machines
- missing find an MCP manifest at the standard paths checked
- missing find an agent plugin manifest
- missing find out whether verified agents are recognised
- missing read the homepage as data rather than as a page
- missing read the developer documentation
- ok      read the prices without running JavaScript

## What a visitor meets
1. **Entry observation** (observed). Primary entry is "Get started – free". 2 steps from the homepage. 1 field, 0 marked required in the visible form. 0 of 1 visible entry-form inputs carry validation attributes; submission was not tested.
## Files generated from this scan
- **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.
- **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/posthog-wtkeb2
## The agent door
- **machine_discoverability** 100/100. 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** 85/100. 3 prices are readable without JavaScript, with no tier sent to sales.
- **agent_aware_instrumentation** 18/100. No MCP manifest was identified at the discovery paths checked. Pricing.md publishes prices in a form an agent can read directly.
- **machine_fetchable_trust** 85/100. Security.txt is published with a contact route. The homepage answers automated requests.
- **commercial_rails** 75/100. Prices are published in raw HTML. A self-serve signup entry was observed from the homepage. Pricing.md is machine readable.
## 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.
