We sent a buying agent

15 requests, in order

The agent got through 9 of 15 requests, but could not find a published agent interface. It came up empty on 5 other checks too. That is enough missing for a machine to give up before it reaches a purchase.

Deep scans need an account. Accounts are free.

A deep scan walks the site with two agents, records cited evidence and screenshots, and keeps a mission timeline. It comes with the paid plans. Making an account costs nothing and gives you one basic scan a month.

The agent door

38 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.

89Strong

No AI crawler is blocked by robots.txt, a real browser is served the page normally, and llms.txt is published with a declared intent for assistants. A sitemap lists 1194 URLs and the homepage carries 9 schema.org types.

4 observations recorded.

Programmatic onboarding

Whether an agent can get working access without a human.

16Blocking

The API documentation at developers.hubspot.com shows endpoint examples but no machine readable specification. A client must be written by hand from prose.

3 observations recorded.

Pricing legibility

Whether total cost can be computed from published numbers.

30Weak

16 prices are rendered on the pricing page but only after JavaScript executes. The raw HTML contains zero prices. A client that does not render pages sees no pricing at all, making cost evaluation impossible without a browser.

1 observation recorded.

Agent-aware instrumentation

Whether you publish anything built for machine callers.

8Blocking

No MCP manifest is published at any of the 3 standard paths checked. No ai-plugin.json is present. The site does not expose machine readable integration points for agents to discover and use its capabilities.

4 observations recorded.

Machine-fetchable trust

Whether terms, security and status are readable as text.

85Strong

security.txt is published at /.well-known/security.txt with a contact route for machines. The homepage responds to automated requests with HTTP 200 and serves structured data.

2 observations recorded.

Commercial rails

Whether a purchase can complete without a sales call.

0Blocking

The pricing page routes to sales without publishing any prices in the raw HTML. Prices appear only after JavaScript renders, and the page is gated to sales for custom quotes. An agent cannot compute total cost from published tiers.

2 observations recorded.

The human door

80 of 100

What a first time visitor meets between landing and first value.

Steps to first value

How far a new visitor travels before something useful happens.

80Strong

The signup page at app.hubspot.com is 2 steps from the homepage. However, robots.txt at app.hubspot.com contains 'Disallow: /' which closes the signup form to automated visitors honouring the standard.

1 observation recorded.

Required fields

How much you ask for before you give anything back.

Not measured
