"description": "Search the CoreLoop business directory. Start here: every other tool on this endpoint needs a business, and each result carries the `business_id` and `slug` you pass to them as the `business` argument. `business_id` is a PUBLIC, OPAQUE, STABLE routing identifier: it is safe to store and re-use across sessions, it stays the same when a business renames itself or changes its slug, and it carries no sensitive information. Treat it as a token — do not parse it, do not derive meaning from its format, and do not construct one. Pass back exactly the value you were given. A result with `asserts_no_physical_location: true` has stated that it has no premises (consultants, trades, online-only) — it is intentionally absent from city search rather than missing data. `false` means no such statement was made; it does NOT imply premises. Results are returned in your requested language when the business has published a translation: send `?locale=<code>` on the endpoint URL (takes precedence) or an Accept-Language header. Each result reports the language it is written in (`locale`), the business's original language (`content_locale`), and every language it is available in (`available_locales`). `mcp_url`, `a2a_url` and `page_url` — and every URL inside `protocol_urls` — are null when that surface is currently switched off for the business: a null is intentional (do not construct the URL yourself), and the business remains reachable through its non-null surfaces. `data_source: \"directory\"` marks these rows as the search projection; call get_business_info for the live profile. PAGING: one call returns at most `limit` results. Read `has_more` — a short page is not proof of the end — and pass `next_cursor` back as `cursor` for the next page. The cursor is opaque and bound to the filters and sort it was issued for: change any of them and it is rejected, so start a new search instead. `limit` may change between pages.",
