Tools: lookup is_vulnerable most_recent_not_vulnerable
lookup | Look up a package by name and (optionally) version number to find which versions are available and/or have vulnerabilities. params: cvss_filter, limit, name*, retain_passing |
is_vulnerable | Check if a specific package version has known vulnerabilities. Requires an exact version specifier (e.g., 'requests==2.31.0'). params: name* |
most_recent_not_vulnerable | Find the most recent version of a package that has no known vulnerabilities. params: name* |
Entries describe changes in tool definitions. They are not statements about a server, its quality or its author. The grade measures how the tool definitions fit model providers (token cost, schema compatibility, confusable names) as scored by the ToolFit engine at the time of the listing. JSON: append .json. Opt-out: how or hello@youraitools.co.
