Did this report tell you something you did not know?

We sent a buying agent

Ten dimensions

Not measured is not zero.

The agent door

43 of 100

What a machine can do on your site with nobody watching.

Machine discoverability

Whether a retrieval system can find and read you at all.

96Strong

No AI crawler is blocked by robots.txt; the site explicitly allows gptbot, claudebot, perplexitybot and others. A real browser is served the page normally. The sitemap lists 75 URLs including product pages.

4 observations recorded.

Programmatic onboarding

Whether an agent can get working access without a human.

10Blocking

No API documentation is linked from the homepage. No OpenAPI spec exists at any of the 4 standard paths checked. The site publishes an MCP manifest but no API surface to call.

3 observations recorded.

Pricing legibility

Whether total cost can be computed from published numbers.

Not measured

Could not verify: this scan did not reach the pages that would show it.

2 observations recorded.

Agent-aware instrumentation

Whether you publish anything built for machine callers.

58Passable

An MCP manifest is published at /.well-known/mcp.json, signalling intent to work with agents. No Web Bot Auth signals are present, which is normal for a young convention.

4 observations recorded.

Machine-fetchable trust

Whether terms, security and status are readable as text.

40Weak

No security.txt file is published; the path returns a web page instead. The homepage serves structured data to automated requests. Trust signals are minimal and incomplete.

3 observations recorded.

Commercial rails

Whether a purchase can complete without a sales call.

10Blocking

No UCP manifest, no storefrontMCP, no payment processor detected on the homepage. No published route for an agent to complete a purchase. The site has no machine-readable checkout path.

4 observations recorded.
