Tool Explorer FAQ

How the directory, categories and Discoverability Score work.

Read the methodology
What is Tool Explorer?

Tool Explorer indexes the callable tool names and descriptions attached to public registry profiles. It is useful for seeing what agents can actually invoke, not just which profile exists.

How do category and verb filters work?

Category filters use the live registry category rollup. Verb filters use the public tool insights rollup, so the page stays backed by the same read models as the tracker charts.

Why do auth requirements matter?

Auth requirements show whether a tool is likely usable without account connection, requires authentication, is private, or is unknown in the current snapshot.
