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 agent got through 8 of 14 requests, but could not find a contact route for machines. It came up empty on 5 other checks too. That is enough missing for a machine to give up before it reaches a purchase.
- 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
- missing 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
- missing read the homepage as data rather than as a page
- missing find a machine readable API spec
- ok      read the prices without running JavaScript
- ok      read the product catalogue as data
- ok      read a product page as data
## Top issues
1. **No MCP manifest was found at the 3 standard paths checked, so an agent has no published machine door to this site.** (agent_aware_instrumentation)
2. **No OpenAPI specification was found at the 6 standard paths checked, so a client must be written from prose instead of generated.** (programmatic_onboarding)
3. **The product feed lacks GTINs, which are required for syndication to most retail networks.** (commercial_rails)
The evidence and the recommended fix for each are on the report page: https://www.seconddoor.io/r/brooklinen-7v6p6e
## Files generated from this scan
- **robots.txt rules for AI crawlers** at `/robots.txt`, 10 minutes, no developer needed. Verify: The next scan reads robots.txt and finds every search and agent crawler allowed, none of them kept off product or pricing paths.
- **Variants missing a GTIN or a brand** at `catalog-identifiers.csv`, 5 minutes, no developer needed. Verify: The next scan reads the catalogue feed and finds a valid GTIN on at least nine in ten variants and a brand on at least nine in ten products.
- **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.
- **security.txt** at `/.well-known/security.txt`, 10 minutes, no developer needed. Verify: The next scan fetches /.well-known/security.txt as text and the security.txt 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.
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/brooklinen-7v6p6e
## The agent door
- **machine_discoverability** 99/100. No AI crawler is blocked by robots.txt or user agent rules; llms.txt is published; the sitemap lists 256 URLs including products; the catalogue answers as JSON at /products.json with brand data on each item; a real browser is served the.
- **programmatic_onboarding** 10/100. No API surface, MCP manifest, or OpenAPI spec was found at any of the 9 standard paths checked. The store is a Shopify instance with a public product feed, but no documented programmatic entry point exists for agents to act without.
- **pricing_legibility** 45/100. Prices are in the raw HTML of the 3 product pages read, 25 prices on the homepage itself, no Product structured data within the first 1.2 MB read of each product page.
- **agent_aware_instrumentation** 14/100. The catalogue answers as data at /products.json, which is agent-aware. No MCP manifest exists at any of the 3 standard paths checked. No other instrumentation for agent coordination was found.
- **machine_fetchable_trust** 40/100. No security.txt file exists at /.well-known/security.txt. The homepage answers automated requests with HTTP 200 and serves a real browser normally. Trust signals are minimal.
- **commercial_rails** 19/100. The catalogue feed at /products.json is open and readable, with brand data on each of 12 products. Shopify stores can syndicate to feeds, but the feed does not publish GTINs, which are required for most product syndication networks.
