236 servers have graduated to an indexed fact sheet.

These listings are unreviewed. They were collected from the registry and from public repositories, or sent in by the community, and they do not yet have enough checked install detail or test data for an indexed page. When a maintainer adds that data, the server graduates. The page at its own URL, when it already has one, stays in place either way.

A server is indexed only when it has a pinned install and a score of at least 40. A pinned install is a package with a version, an OCI image tag other than latest, a remote URL, or a reference install command. The score adds 16 points for a unique description of at least 60 characters (plus 6 at 100 characters and 4 at 140). Harvest text that says “official registry” or “Declared transport” scores zero for description. Install is 18 points, plus 4 when two install forms are present, plus 4 when a secret or required header, environment variable, or argument is declared. Vendor is 8 points and reference is 10. GitHub stars add 4 at 50, 8 at 200, 16 at 1,000, and 22 at 5,000. A verified initialize and tools/list probe is 16 points. Any other recorded probe is 6. Repository, license, last commit, and website add 1 each. One substance signal is also required: the unique description, at least 1,000 GitHub stars, a verified probe, or reference-server status. At most 300 servers are indexed. Past that line, the highest scores stay, with ties broken by GitHub stars, then description length, then slug. Payment, Featured, and Sponsored are not part of this score and do not add points. A paid server that does not clear the score stays in the vault. Paid listings (Sponsored, then Featured) are still displayed first on every list that includes them, marked Advertisement. Organic listings follow, sorted by GitHub stars. Paying doesn't change a server's GitHub stars, third-party ratings, Verified status, or listing data.

Email the install docs or the test data to [email protected]. There is no account. That message verifies ownership or updates the listing. Paying doesn't change a server's GitHub stars, third-party ratings, Verified status, or listing data.
