What the record holds for one MCP server, skill or plugin: versions on record, the tools read from the pinned version, how many releases changed the small print and the worst grade, and the advisories that name it. Use it first, when nothing about the entry is known yet, or to confirm an entry exists before the other tools; use changes_since for the diffs and advisories_for for advisory detail. Not for private or unpublished servers, which have no page. Read-only: one HTTPS GET to smallprint.dev per call, no account, no key, nothing about the caller sent, and the server or skill asked about is never run or contacted. Rate limited to one entry per request; a 429 answer says to wait a minute. A name not in the catalog returns a plain error, not a guess.

The releases of one entry whose tool descriptions, schemas or instructions changed, each with its diff, its grade and the rule that graded it (rules at https://smallprint.dev/how-we-grade). Use it to read what actually changed, after lookup_entry or changed_since_approval said something did; use changed_since_approval instead when the question is only whether anything changed since an approved version. Filters: since keeps releases published on or after a date; min_severity drops changes below a grade (default low, so plain version bumps and identical releases are never listed). Returns at most 12 releases in text; the structured result carries all of them. Read-only: one HTTPS GET to smallprint.dev per call, no account, no key, nothing about the caller sent, and the server or skill asked about is never run or contacted.

Every public security advisory on record that names one entry, each attributed to the database or report that published it, with its severity criterion and the affected version range. Use it when deciding whether a specific version is inside a known advisory, or after lookup_entry reported advisories; it adds nothing for an entry with none. Small Print attributes and never judges: the severity is the source's or a printed CVSS band.

Yes or no, before using a server or skill: has its small print changed since the version, content hash or date that was reviewed? The answer opens with UNCHANGED, CHANGED or UNKNOWN, then the releases that changed it since and their worst grade, then whether the review can stand. Use it on every run when an approval is on file, instead of re-reading the tools; use lookup_entry when nothing was approved yet and changes_since to read the diffs after a CHANGED answer. UNKNOWN means the approved version is not on record or its small print was never read, so nothing is compared; treat it as no answer, not as safe.
