30 sites in the index share the category programming languages and frameworks. 3 transactional sites share it.
How we grade
Three tiers. Every listing shows which one it has reached, and when. The rubric.
tier 1Declared
The site says agents are welcome in its robots.txt. A permission, not a capability.
tier 2Probe-verified
We fetched the site and tested each signal ourselves. Dated, repeatable, re-checked on a schedule.
tier 3Behaviourally verified
An agent completed the action end to end — booked, bought, submitted — and it worked.

2 checks did not pass when we last looked: API catalog, MCP endpoint answers tools/list. Each is a small, specific fix; the rubric says exactly what we look for.
Behavioural verification — an agent completing your key actions end to end, with the date published here — opens to a small founding cohort first. Leave an email to be in it.

How we found this site: probe discovery. This site didn’t declare agent access — we found it by checking the open web. Everything above was tested the same way, against the same rubric, on the date shown. How we choose what to check, and how to opt out →
