Agent door only. The human door could not be measured on this scan. A Door Gap needs both doors, so this scan does not report one.
## What the machine actually did
The scanner recorded successful observations for 11 of 14 checks, but could not find a published agent interface. It came up empty on 2 other checks too. 1 checks 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 a published agent interface
- missing find an agent plugin manifest
- missing find out whether verified agents are recognised
- ok      read the homepage as data rather than as a page
- ok      find a machine readable API spec
- ok      read the developer documentation
- ok      read the prices without running JavaScript
- ok      find a comparison page worth citing
## Top issues
1. **No MCP manifest was identified at the 3 standard paths checked.** (agent_aware_instrumentation)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/supabase-eyb5ja
## Files generated from this scan
- **Pricing as Offer structured data** at `pricing page`, 20 minutes, developer. Verify: The next scan reads Offer structured data with a price and currency on the pricing page, and the pricing check credits it.
- **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.
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/supabase-eyb5ja
## The agent door
- **machine_discoverability** 100/100. Robots.txt names 4 AI crawlers and allows them. on its first visit, our browser read the homepage. no user agent rule refused the tested retrieval crawler names. prices on the checked pages are readable without running JavaScript.
- **programmatic_onboarding** 45/100. A machine readable API spec is published.
- **pricing_legibility** 85/100. 102 prices are readable without JavaScript, with no tier sent to sales.
- **agent_aware_instrumentation** 50/100. No MCP manifest was identified at the discovery paths checked. robots.txt names 4 AI crawlers and allows them. pricing.md publishes prices in a form an agent can read directly. a machine readable API spec is published.
- **machine_fetchable_trust** 85/100. Security.txt is published with a contact route. the homepage answers automated requests.
