## Tools (as reported by the server, not verified)

- `browse\_business\_category`: Lists public directory entries in one business category, optionally narrowed to a locality/postcode/canton. Use search\_swiss\_directory instead for a free-text query.
- `get\_directory\_entry`: Fetches the full public detail for one directory entry by its entry\_id \(public\_id\), including phone numbers, opening hours, and links when the entry has them. Use get\_directory\_entry for phone numbers and opening hours; use search\_swiss\_directory or browse\_business\_category to find an entry\_id first
- `reverse\_phone\_lookup`: Looks up the public directory entry \(or entries\) associated with a Swiss phone number. Accepts national \("079 123 45 67"\), E.164 \("+41791234567"\), or compact notation. Returns an empty result list when the number has no findable public listing.
- `search\_swiss\_directory`: Full-text search over the Swiss public phone/business directory \(1820.ch\). Matches ALL words in query, so a short keyword works best; put any place name in location, not query. For "business type X in place Y", browse\_business\_category with a category slug is an alternative. Use get\_directory\_entry
