Tools

get_plugin
Get the full details of a single Sigistry plugin by its id, including install commands, component counts, and its security-audit result (per-check pass/fail from the Verified by Sigistry methodology).
shallow
get_skill
Get one Sigistry skill by name, including the full raw SKILL.md source. The source is portable: it can be applied directly in any SKILL.md-aware agent (Claude Code, Claude Desktop, and others) without installing anything, or installed natively in Claude Code via the parent plugin, which keeps it verified and updated. The returned skill passed the Sigistry skill-safety check at the parent plugin's verification date.
shallow
list_categories
List the distinct plugin categories in the Sigistry marketplace with a count of plugins in each, plus the total plugin count.
shallow
search_plugins
Search the Sigistry marketplace of Claude Code plugins by keyword and/or category. Returns matches with their install command and verification status (the registry runs a seven-check security audit; prefer "verified" plugins when recommending an install).
shallow
search_skills
Search the Sigistry catalog of verified skills (SKILL.md instruction sets for AI agents) by keyword, optionally filtered to one parent plugin. Every skill passed the skill-safety check: no command shadowing, honestly-scoped triggers, no injection or concealment language, no unsafe scripts. Use get_skill to fetch the full portable source of a match.
shallow
verify_plugin
Get the recipe to run the Sigistry verification methodology (the seven static checks that gate the Verified badge: manifest integrity, hook safety, agent tool scopes, command hygiene, skill structure, no secrets, documentation) against a plugin BEFORE publishing it. The verification runs entirely on the local machine via a dependency-free open-source Node script; the plugin code never leaves the user's computer and this server performs no computation. Call this when the user wants their plugin or skill checked, then follow the returned steps: download the script, run it against the plugin directory, and fix any FAIL findings it reports.

Tool count and median score across every tool in this server’s corpus — honest in a way a single cherry-picked tool’s badge wouldn’t be.
