Free, no account needed. The checkers tell you what is broken. The generators help you publish what agents and other software need in order to read your site properly.
Checkers
Generators
UCP profile generator
Answer a few questions about how agents can buy from you and get a valid
/.well-known/ucp profile, plus the server rule to serve it.
llms.txt generator
Produce an llms.txt describing your site's important pages in a form built for machine readers.
llms-ctx generator
Produce the expanded context file, with the content inlined rather than linked.
JSON-LD generator
Structured data for products, articles, FAQs, how-tos, events and local businesses.
Crawler and agent directories
Look up what is visiting your site, what it publishes, and whether you can verify it.
Want this to run itself?
Monitoring runs these checks daily and emails you when a deploy breaks something, so a regression is caught the morning it ships instead of when a customer mentions it.
