list_categories
shallowcom.openshopgraph/mcp · Verify this server
Enumerate the shop category taxonomy: every category slug currently carried by at least one public shop, together with how many public shops carry it. Call this BEFORE passing `category` to find_shop — the taxonomy is flat (no parent/child hierarchy, e.g. "fashion" and "womens-clothing" are siblings, not nested) and its slugs come from observed data, not a fixed enum baked into this tool, so a slug cannot be reliably guessed. `find_shop(category: <slug>)` only accepts a slug returned here; giving it anything else fails with an error instead of silently returning no results. Coverage measured 2026-09-03: 171 slugs across 3036 of 3100 active shops (97.9%) — a shop can carry more than one category, so counts do not sum to the total shop count.
