Three read-only MCP abilities, category lh-buddypress-group-taxonomies. All are gated to BuddyPress’s bp_moderate capability (matching this plugin’s own capability model for taxonomy management), not install_plugins — term data isn’t developer/admin tooling here. They only ever operate against taxonomies registered on LH_BP_Group_Taxonomies_Taxonomy::$taxonomies (i.e. those added via the lh_bp_group_taxonomies_taxonomies filter), never arbitrary caller-supplied taxonomy names.

AbilityNotes
list-group-taxonomiesLists the taxonomies this plugin currently manages, with each taxonomy’s label, hierarchical flag, and term count. May return an empty list if no companion plugin has hooked in.
list-termsLists the terms for a single managed taxonomy, with each term’s group count. Takes taxonomy (required) and hide_empty (default false).
get-groups-by-taxonomyFinds groups matching one or more taxonomy terms, returning each matching group with its own term assignments across every managed taxonomy. Accepts either a simple taxonomy + terms (+ optional field/operator) shape, or an advanced tax_query — a WP_Tax_Query-shaped array of clauses, optionally with a top-level relation key for multi-taxonomy AND/OR combinations. Supports optional status filtering and pagination (per_page/page).

See also LH MCP BuddyPress Queries (lh-mcp-buddypress-queries) for the sibling plugin’s non-taxonomy-scoped group/membership/activity/directory query abilities.
